Definitions

  • the present invention relates to a device for the gentle vertical transport of mechanically sensitive small pieces such as tablets, film tablets, coated tablets or capsules.
  • DE-PS 40 41 706 it is proposed to produce an air flow directed from the bottom upwards when the tablets are conveyed via conveyor tubes from a higher location to lower-lying transport containers in the conveyor tubes, so that the tablets sink slowly against the resistance of the air flow.
  • a disadvantage of this method is the difficult control and adaptation of the air flow to the material to be conveyed and the mechanical load on the material to be observed, particularly in the event of turbulence.
  • the applicant's patent application EP-A-96 102 157 proposes a device for conveying mechanically sensitive small-sized goods over a closed pipe running obliquely downwards, the pipe being moved back and forth inside the pipe between the two ends of the pipe. has the plug substantially filling the inner cross-section of the tube; the plug is moved back and forth by a thread connected to a cable winch or by compressed air in the tube, which enables the small-sized goods to be transported in a manner which is gentle on the quality.
  • the object of the present invention is therefore to provide a device with which vertical transport of small-sized goods to a lower level is made possible. Quality-friendly transport of the goods must be ensured in such a way that there is no significant abrasion or breakage. Furthermore, different level differences must be manageable with the system, and it must be usable for different types of goods, such as the tablets, film tablets, coated tablets or capsules mentioned above.
  • the object is achieved by a hollow body which has tabs which protrude inwards and which are attached to one another on the inside and which yield under the weight of the item and thus pass it on downward.
  • the object of the invention is therefore a device for the vertical conveyance of finely divided goods to a lower level with a hollow body, which has on one inside one another, inwardly projecting tabs, which give way under the weight of the goods and thus pass them downward.
  • a suitable dosage form which, depending on the area of use, can be, for example, a tablet, a film tablet, a dragee or a capsule.
  • a suitable dosage form which, depending on the area of use, can be, for example, a tablet, a film tablet, a dragee or a capsule.
  • the resulting good often has to be placed in containers which are located below the machine. In the simplest case, the container is on the floor of the room in which the tablet or capsule filling machine is also located.
  • the hollow body according to the invention can consist of the usual materials known to a person skilled in the art.
  • Plastics such as polyethylene, polypropylene, polyethylene, polypropylene copolymers, polystyrene, polycarbonates are suitable.
  • Metals such as stainless steel or aluminum are also suitable.
  • the hollow body according to the invention can have any suitable inner profile. It can be a tube, but also a square profile. Of course, hollow bodies with many different inner profiles are suitable for carrying out the invention, for example triangular hollow bodies.
  • the hollow body is open on one side and this opening is then closed with a corresponding profile as a cover or cover. This makes it easy, for example, to attach the inwardly projecting tabs; they are inserted on the open side and fastened there. It is particularly advantageous if devices are attached to the open side with which the tabs can be fixed. Recesses can be used for this purpose, in which the inwardly projecting tabs are hung. By subsequently attaching the cover profile the rags are then fixed. Due to the removable profile, the hollow body can then be easily cleaned in the event of contamination, and any damaged rags can also be easily replaced.
  • the tabs are attached to the inner wall of the hollow body only on one side.
  • the flaps can be dimensioned so that they protrude rigidly into the interior, but also so that they already bend due to their own weight. They can be of a length such that they overlap one another, lie against the opposite inner wall or form a narrow, narrow passage or gap in the hollow body.
  • the inwardly projecting lobes can advantageously be applied over the entire length of the hollow body or even only approximately in the lower region, shortly before the outlet, in order to brake the material.
  • Suitable materials for the rags are the elastomeric plastics known to a person skilled in the art, such as silicone, known synthetic rubbers, such as styrene-butadiene rubber or butyl rubber, or natural rubber.
  • the flaps can also be provided on the surface with a material such as Teflon, which enables the material to slide easily.
  • the device according to the invention advantageously has a product task, such as a filling shoe or a filling plug.
  • the throughput through the hollow body is regulated not only by the structural features but also by the amount of the material supplied and the material removed below after it emerges.
  • the vertical transport of the small-sized goods is advantageously carried out in a continuous form with the device according to the invention.
  • the lobes protruding inwards in the hollow body act as a brake in their entirety on the "flow" of the small-sized goods.
  • the device according to the present invention can be equipped with sensors for monitoring the control of the throughput, such as light barriers.
  • sensors for monitoring the control of the throughput such as light barriers.
  • the device can also be moved up manually or automatically (sensor-controlled).
  • FIG. 1 is a representation of a hollow body according to the invention, which has flexible tabs on an inside.
  • FIG. 2 shows a continuous tablet flow in the device according to the invention according to FIG. 1.
  • Fig. 1 shows the embodiment of a hollow body (1) according to the invention, which has tabs (2) on its inside in an oblique installation position in a ceiling (5).
  • the hollow body (1) can be slidably mounted on rollers in the ceiling (5) in a correspondingly inclined casing.
  • a product task (3) is also drawn.
  • the tabs (2) are only attached on one side and are dimensioned so that they extend to the opposite inner wall.
  • the dimensions of the tabs (2) are preferably selected so that they bend due to their own weight and rest on the opposite wall.
  • the cloth (2) is lifted off the wall by the material fed from above through the product feed (3), as a result of which the material is braked and gently transported downwards.
  • the tabs (2) can also be manufactured in such a way that they do not sag, but rather extend straight into the interior and extend to the opposite wall. This can increase the braking effect, for example, when heavier goods are conveyed through the hollow body (1).
  • the embodiment described with bending flaps is preferably suitable for transportation with an obliquely attached hollow body (1).
  • a lateral offset is made possible in addition to overcoming the height difference.
  • a vertical attachment of the hollow body (1) is also possible, possibly with a change in the dimensioning and the material of the tabs (2) up to the embodiment described with straight tabs. It is easily possible for a person skilled in the art to select the suitable material and the suitable dimensions for producing the device according to the invention, depending on the type of goods to be transported, and to determine the suitable installation position.
  • the angle at which the lobes protrude into the interior of the hollow body (1) is highly variable and depends on the strength and bending strength of the lobes and the angle of attack of the hollow body (1).
  • the rags (2) can be replaced with brushes.
  • FIG. 2 shows a continuous stream of tablets (4) in the embodiment according to the invention of a hollow body (1) with lobes (2) lifted off.
  • the material to be conveyed can pass through the device according to the invention without any appreciable formation of jams.
  • a hollow body of the embodiment according to FIG. 1 with sagging lobes is used as the hollow body for conveying the small-piece goods.
  • the hollow profile consists of a 3 m long slotted stainless steel box profile with the dimensions 75 x 75 mm.
  • holders for silicone tabs are hung at a distance of 100 mm.
  • These holders consist of 1.5 mm thick stainless steel sheet and are angled by approximately 30 ° towards the inside of the box.
  • the length of the angled part is approximately 8 mm; the end of the angled part is bent upwards to accommodate the silicone tabs.
  • the silicone flap which has a material thickness of 2 to 3 mm and dimensions of 200 x 73 mm, is hung in the holder.
  • the box profile for fixing the holder is closed with a cover, which in the present case is a sliding snap lock.
  • the lumpy good is entered into the hollow body.
  • a height difference of 2,600 mm with a lateral offset of 1,500 mm can be overcome.
  • the material to be conveyed emerges from the tablet chute without any significant dust formation.
  • the installation position should not be less than 30 ° from the vertical, since otherwise the braking effect of the tabs is no longer guaranteed. Furthermore, 45 ° should not be exceeded, since from such an angle the material is braked too much by the friction with the inner wall of the hollow body and no longer slips accordingly.
  • the conveyor can be easily dismantled and cleaned.
