Description

The invention relates to a weighing device for a capsule, which is held in a capsule segment arranged on a turntable of a capsule filling machine, and a capsule filling machine with such a weighing device.

Pharmaceutical products, products from the field of food supplements or the like are often administered as a unit dose in a push-fit capsule, for example made of hard gelatine. Such push-fit capsules are delivered empty and filled with the desired content on capsule filling machines. For this purpose, capsule filling machines are used, which are widely designed as rotary machines with a rotary table. So-called capsule segments are arranged on the turntable, each of which has several capsule receptacles arranged in a row for one capsule each. The turntable can be moved step by step in a plane of rotation in such a way that the capsule segments sequentially pass through different processing stations. Typical steps that are carried out at the individual processing stations are the opening of the empty, initially still closed capsules, the filling and closing of the same, testing, ejection of bad capsules and finally the ejection of the capsules classified as properly.

In the case of sensitive products, so-called AMV sensors (Advanced Mass Verification) are increasingly being used, by means of which the individual masses of the filling quantities are checked in a capacitive manner. A precise and verifiable calibration of the MV sensors is required for reliable MV mass determination. This is done using weighing cells in which individual capsules are weighed when empty (tare) and when filled (gross). The mass of the filling can be determined from the difference between the gross and tare results, which can then be used as a reference value for the MV calibration.

For weighing the empty or full capsules, load cells with only a single weighing receptacle for a single capsule have proven to be effective, as these provide more accurate results compared to weighing several capsules at the same time. For weighing, the capsules must be removed from the capsule segments and transported to the weighing cell.

For this, the DE 10 2018 200 068 A1 a device in which a transport segment called a capsule pick-up takes the capsules from the capsule segment of the turntable and then feeds them individually to the weighing pick-up. The capsule segments of the turntable each have two rows of capsule receptacles. Correspondingly, the transport segment is also equipped with two rows of transport receptacles for one capsule each.

In order to now deposit the taken capsules individually in the weighing receptacle of the weighing cell, the transport receptacles of the transport segment must each be brought into overlap with the weighing receptacle. This is done by a sequence of movements in a transport plane parallel to the plane of rotation of the turntable, namely in two combined degrees of freedom of movement. The desired positioning of the transport receptacles in overlap with the weighing cell can be brought about by combined pivoting and / or linear movements. This requires a high degree of positioning accuracy with a corresponding effort. In addition, the effort and coordination of the two degrees of freedom of movement place considerable demands on the mechanical and control-related design.

The invention is based on the object of developing a generic weighing device in such a way that the transfer of a capsule from the capsule segment of the capsule filling machine to the weighing cell and back is simplified and accelerated.

This object is achieved by a weighing device with the features of claim 1.

The invention is based on the object of specifying a capsule filling machine in which a calibration of an existing MV sensor and / or an ongoing in-process control can be carried out quickly and with little effort.

This object is achieved by a capsule filling machine with the features of claim 8.

According to the invention, a weighing device is provided in which a funnel element is arranged above the weighing receptacle of the weighing cell. The funnel element has a lower dispensing opening corresponding to the weighing receptacle, an upper catching opening that is larger in comparison to the dispensing opening, and a centering channel extending from the catching opening to the dispensing opening. The transport segment can be moved in the transport plane with only a single degree of freedom of movement in such a way that the transport receptacles of the transport segment can be brought into the catchment area of the catch opening of the funnel element. Since the funnel element is a passive element without its own movement, and since the transport segment only has to be moved in a single degree of freedom, the control effort is low. There is no need for coordination with other degrees of freedom of movement. Because of the only one It is true that the degree of freedom of movement cannot overlap with the weighing receptacle of the load cell for all transport receptacles. However, this is deliberately avoided. The lack of such an overlap is compensated for by the funnel element. The requirements placed on the positioning accuracy are only minor, since the funnel element can compensate for positional tolerances. In any case, an individual capsule can easily be transferred from the capsule segment of the capsule filling machine to the weighing cell and back.

The only degree of freedom of movement can be one-dimensional linear movement. Preferably, however, the transport segment is pivotable about a pivot axis in the transport plane as the sole degree of freedom of movement. With little constructive and technical control effort, a stiff, fast and repeatable movable design can be realized.

It can be useful to mold the funnel element onto the weighing receptacle. However, the funnel element is preferably designed separately from the weighing receptacle. As a result, the weighing receptacle can be kept small and light, which benefits the weighing accuracy.

In an advantageous development of the invention, the transport receptacles of the transport segment have a funnel section that widens downwards. This not only facilitates the transfer of the capsule from the transport segment to the weighing receptacle, but also helps the capsule to thread itself into the transport receptacle during the return transport from the weighing receptacle. A lower transfer opening of the funnel section preferably corresponds in shape and size to the upper catch opening of the funnel element and is also positioned on the transport segment in such a way that it can be brought into overlap with the upper catch opening of the funnel element. As a result, there are no protrusions, edges or the like on which the capsule could get caught. A clean and quick capsule handover is ensured in both handover directions.

For holding the capsule in the transport receptacles of the transport segment, various, for example form-fitting or pneumatic means come into consideration. The transport receptacles are preferably designed as clamping receptacles with a clamping element for the capsule. In particular, the clamping element is designed in the form of a brush. As a result, the capsule can on the one hand be securely held with the simplest means and on the other hand be pushed in or out without considerable effort and without the risk of damage.

1 shows in a plan view the central part of a capsule filling machine designed according to the invention 20th for filling capsules 1 ( 3 ) with a product. The filling material can be provided in the form of a powder, granules, tablets or the like. This can be a pharmaceutical preparation, a food supplement or the like. The capsules 1 consist of a lower capsule part and an upper capsule part attached to it, both of which are made from hard gelatine, for example.

The capsule filling machine 20th after 1 includes a turntable 21 that is rotating around a vertical axis of rotation 24 according to an arrow 25th can be driven in clocked steps. On a peripheral area of the turntable 21 is a number of capsule segments at regular angular intervals 22nd arranged. In the exemplary embodiment shown, there are a total of ten capsule segments 22nd intended. However, a different number can also be expedient. In the preferred embodiment shown, the capsule segments contain 22nd one Number of capsule receptacles 23 for taking the capsules 1 which are each arranged in a linear, straight line. In the present case, each capsule segment has 22nd a series of five capsule shots 23 , but a different number may also be appropriate.

From the 1 it becomes clear that each capsular segment 22nd of one fixed to the circumference of the turntable 21 attached lower segment part 28 as well as a segment upper part which can be swiveled relative thereto 29 consists. Around the turntable 21 around there are several stationary ones, so not with the turntable 21 rotating processing stations 31 until 40 positioned, which are only shown schematically and not in detail.

The number of processing stations 31 until 40 corresponds to the number of capsule segments 22nd so that in every rotary position of the turntable that is incremented in angular steps 21 each capsule segment 22nd one of the processing stations in the access area 31 until 40 comes to rest.

According to the preferred embodiment shown, starting with the first processing station 31 initially temporarily assembled empty capsules consisting of the lower part and the upper part of the capsule in the row of capsule receptacles 23 used, with a separation of the attached capsule upper part from the capsule lower part then also in normal operation. The next processing station is a separation station 32 . At the transition from the insertion and separation station 31 to the separation station 32 becomes the segment top 29 with the capsule upper parts held therein opposite the segment lower part 28 pivoted with the capsule lower parts held therein. Defective, unseparated empty capsules are returned to the separation station 32 eliminated.

To the exit station 32 a total of three filling stations follow here 33 , 34 , 35 in which the in the segment subdivide 28 The lower parts of the capsule held are filled with the intended filling material. It can also be sufficient to provide only one or two filling stations.

After passing through the last filling station 35 takes place in a swiveling station 36 a pivoting of the segment upper part 29 back into the aligned position relative to the segment lower part 28 . In the subsequent closing station 37 are the capsules 1 closed by pushing the previously removed or separated upper capsule parts back onto the filled lower capsule parts and locking them into place. To the closing station 37 closes a control station 38 at. In the control station 38 are tested and found to be bad capsules 1 ejected. In a subsequent ejection station 40 the remaining capsules found to be good 1 ejected by means of not shown plungers or other ejection means.

In terms of an in-process control (IPK), the weight of the capsules or their filling is determined. The filling stations 33 , 34 , 35 be equipped with so-called MV sensors, by means of which the mass of the individual fillings is capacitively determined and controlled. The structure in this regard and the corresponding method belong to the known prior art and are therefore not shown here in more detail for the sake of simplicity.

According to the invention, a weighing device is additionally provided for calibrating the MV sensors or for an independent in-process control (IPK) 2 for the capsules 1 ( 2 until 7th ) intended. It is an example of a weighing station here 39 between the control station 38 for bad ejection and the ejection station 40 for the good capsules 1 positioned. The weighing device 2 includes a load cell 3 as well as a transfer device 5 for transferring at least one capsule 1 from the capsular segment 22nd to the load cell 3 and back. The load cell 3 only has a single weighing record 4th for a single capsule 1 on. Structure and function of the weighing device according to the invention 2 result from the description of the 2 until 7th :

2 shows the weighing device in an enlarged schematic plan view 2 after 1 with further structural, geometric and kinematic details. The transfer device 5 includes a transport segment 6th with several transport receptacles arranged in a straight line 7th for one capsule each 1 . Distance and number of transport recordings 7th correspond to those of the capsule recordings 23 of the capsule segments 22nd ( 1 ). From the synopsis of the 1 and 2 it also shows that the transport segment 6th in one to the plane of rotation of the turntable 21 parallel transport plane E and movable with its transport receptacles 7th in overlap with the capsule receptacles 23 of the assigned capsule segment 22nd ( 1 ) can be brought. The transport level E corresponds to 1 and 2 the drawing plane. The transport segment 6th can be moved in said transport plane E with only a single degree of freedom of movement, a pivoting movement about a vertical pivoting axis being preferred here 12th according to an arrow 16 is chosen. However, this single degree of freedom of movement in plane E does not include any movement perpendicular thereto, for example a lifting movement parallel to the pivot axis 12th the end. The pivot mechanism can be designed so that one or two of the transport receptacles 7th exactly about the only one Weighing recording 4th be driven. the end 2 however, it becomes clear that due to their straight-line arrangement, a pivoting movement of the individual transport receptacles 7th takes place on different radii in a range between a smallest radius R ₁ and a largest radius R ₂ with a radius difference of ΔR. The alignment of the pivot mechanism in connection with its only degree of freedom of pivoting movement can therefore not take place in a way in which all transport receptacles 7th in overlap with the only weighing receptacle 4th are bringable.

• 3 zeigt in einer vergrößerten Längsschnittdarstellung das über einem Kapselsegment 22 positionierte Transportsegment 6 mit einer in einer Kapselaufnahme 23 gehaltenen Kapsel 1. In der gezeigten Schnittdarstellung sind nur eine einzelne Kapselaufnahme 23 mit einer Kapsel 1 und eine einzelne Transportaufnahme 7 dargestellt. Diese und die übrigen Transportaufnahmen 7 bzw. Kapselaufnahmen 23 liegen in Überdeckung miteinander. Aus der Zusammenschau mit 4 ergibt sich die Übergabe der Kapsel 1 vom Kapselsegment 22 an das Transportsegment 6 wie folgt:
  • Durch jeweils einen unteren Stößel 26 lässt sich die Kapsel 1 von unten aus der Kapselaufnahme 23 des Kapselsegments 22 heraus nach oben in die Transportaufnahme 7 des Transportsegmentes 6 drücken. Ein oberer Stößel 27 dient hier zunächst als Stopper für die Kapsel 1, sodass diese in der gewünschten axialen Position in der Transportaufnahme 7 zu liegen kommt. Die in axialer Richtung durchgehenden Transportaufnahmen 7 sind als Klemmaufnahmen für die Kapsel 1 ausgebildet und weisen dazu in ihrem oberen Bereich einen Klemmabschnitt 17 mit einem Klemmelement auf. Als Klemmelement ist hier eine angedeutete Bürste 15 gewählt, welche die Kapsel elastisch federnd in radial eine prismatische Aufnahme des Klemmabschnitts 17 drückt. Die solchermaßen in den Klemmabschnitt 17 übergebenen und dort gehaltenen Kapseln 1 lassen sich nun durch die in den 1 bis 2 dargestellte Schwenkbewegung des Transportsegmentes 6 in den Bereich der Wiegezelle 3 verschwenken, was in den 2 und 5 bis 7 gezeigt ist.

To compensate for this fact, according to the representation according to the 5 until 7th above the weighing receptacle 4th the load cell 3 a funnel element 8th arranged, the function of which is described below. But first let's focus on the transport segment 6th with his transport recordings 7th in interaction with the capsule segments 22nd detailed:

• 3 shows in an enlarged longitudinal sectional view that above a capsule segment 22nd positioned transport segment 6th with one in a capsule holder 23 held capsule 1 . Only a single capsule holder is shown in the sectional illustration shown 23 with a capsule 1 and a single transport recording 7th shown. These and the other transport recordings 7th or capsule receptacles 23 are in overlap with each other. From the synopsis with 4th results in the transfer of the capsule 1 from the capsular segment 22nd to the transport segment 6th as follows:
  • With a lower pestle each 26th lets the capsule 1 from below from the capsule holder 23 of the capsule segment 22nd out upwards into the transport receptacle 7th of the transport segment 6th to press. An upper ram 27 serves here initially as a stopper for the capsule 1 so that they are in the desired axial position in the transport receptacle 7th comes to rest. The transport receptacles that go through in the axial direction 7th are as clamp mountings for the capsule 1 and have a clamping portion in their upper area 17th with a clamping element. A brush is indicated here as the clamping element 15th selected, which the capsule is elastically resilient in a radially prismatic receptacle of the clamping portion 17th presses. In such a way in the clamping section 17th capsules handed over and held there 1 can now be accessed through the 1 until 2 illustrated pivoting movement of the transport segment 6th in the area of the load cell 3 pivot what is in the 2 and 5 until 7th is shown.

5 shows in an enlarged longitudinal sectional view that above the weighing receptacle 4th positioned transport segment 6th with the interposition of said funnel element 8th at the beginning of the capsule transfer to the weighing cell 3 . The funnel element 8th is above the weighing receptacle 4th the load cell 3 positioned. It has a lower dispensing opening 10 corresponding to the weighing recording 4th , an upper one compared to the dispensing opening 10 larger opening 9 and one from the trap opening 9 to the dispensing opening 10 extending centering channel 11 on. The trap opening 9 is designed in shape and size in such a way that all transport receptacles 7th of the transport segment 6th with their lower openings in spite of the related 2 explained difference in radii .DELTA.R in the catchment area of the catchment opening 9 are bringable.

In addition it shows 5 nor that the transport shots 7th of the transport segment 6th below the already mentioned clamping section 17th each a downward widening funnel section 13th have, the funnel portion 13th down in a transfer opening 14th ends. The lower transfer openings 14th of the transport segment 6th correspond in shape and size to the upper trap opening 9 of the funnel element 8th . You are like that on the transport segment 6th positioned, and the transport segment is so to the load cell 3 with the funnel element 8th aligned that all transfer openings 14th by means of the pivoting movement of the transfer device explained above 5 despite the difference in radius ΔR in overlap with the upper trap opening 9 of the funnel element 8th are bringable. This coverage is in the 5 until 7th shown.

As soon as a certain desired transport recording 7th of the transport segment 6th into the catchment area of the catchment opening 9 of the funnel element 8th is brought, now follows the capsule transfer from the transport segment 6th to the load cell 3 through the funnel element 8th through. 6th shows the arrangement after 5 during the mentioned capsule transfer. The capsule 1 was moved downwards out of the transport receptacle by a movement element (not shown) such as a plunger 7th ejected and is now in the funnel element 8th . It can be seen that the funnel element 8th the difference in radius ΔR is overcome by passing it through the correspondingly large opening 9 which do not overlap with the weighing recording 4th located capsule 1 captures and relative to the weighing recording 4th centered. For the process of centering there is one lower dispensing opening 10 of the funnel element 8th centrically above the weighing receptacle 4th .

7th finally shows the arrangement according to the 5 and 6th after the capsule handover has been completed. The capsule 1 is located in the Weighing recording 4th after going through the lower dispensing opening 10 of the funnel element 8th fell in there. The capsule 1 is now weighed. It can be seen that the funnel element 8th separate from the weighing recording 4th is trained and is therefore not included in the weight. Nonetheless, the funnel element is 8th Fixed in a fixed position to the load cell, so it is not installed together with the transport segment 6th pivoted.

After the in the weighing recording 4th lying capsule 1 was weighed individually, it is then taken from the weighing recording 4th pushed out. For this purpose, too, a movement element (not shown) such as, for example, a plunger is provided which the capsule 1 the reverse of the sequence described above from below through the funnel element 8th through ( 6th ) back into the associated transport receptacle 7th of the transport segment 6th ( 5 ) where it pushes again through the clamping element in the form of the brush 15th is held. When transferring from the funnel element 8th to the transport segment 6th becomes the radius difference ΔR through the funnel section 13th the transport recording 7th overcome.

Now after the capsule 1 back to its position in the transport receptacle assigned to it 7th corresponding 5 has taken, more can also be found in the transport segment 6th held capsules are weighed. The transport segment 6th sequentially pivoted in such a way that sequentially all or only a selected part of the transport receptacles 7th in the catchment area of the catchment opening 9 of the funnel element 8th lie. The previously described procedure of capsule transfer from the transport segment then takes place in each case 6th for weighing 4th and back, with the respective capsule weighed in between 1 .

After weighing the desired number of capsules 1 becomes the transport segment 6th from in to 2 and 5 until 7th shown weighing position back to the original position after the 1 , 3 and 4th panned. Conversely to the above in connection with the 3 , 4th The procedure described is the capsules 1 from the transport recordings 7th of the transport segment 6th out by means of the upper ram 27 back into the capsule receptacles 23 of the capsular segment 22nd pressed. The capsules weighed and returned in this way 1 can now by means of the above in connection with 1 described clocked movement of the turntable 21 be fed to the next processing station.

One application in practice is the calibration of the MV sensors (not shown) of the filling stations, which was already mentioned at the beginning 33 , 34 , 35 by means of a gross tare weighing. For this purpose, empty capsules of the capsule filling machine 20th ( 1 ) in the first processing station 31 supplied, but not opened. When closed, they become a weighing station 39 driven and weighed there empty (net). After weighing the empty capsule 1 and returning them to the capsular segment 22nd it becomes an inserting and separating station again 31 proceed and this time separately. The capsule is now filled and pre-closed at the corresponding processing stations 1 which then again, but this time filled (gross) at the weighing station 39 is weighed. After returning to the capsule segment 22nd This is followed by a good / bad sorting and an ejection of the capsule 1 . The difference between the results of the gross and net weighing results in the mass of the filling actually contained in the capsule. The value of this mass is now used as a reference value for the calibration of the MV sensors mentioned. The capsule is responsible for the process mentioned 1 two to three revolutions on the turntable 1 the end.

Alternatively, the embodiment according to the invention can also be used for an independent in-process control (IPK). For this purpose, it can be useful to use the weighing device 2 deviating from the illustration according to 1 between the closing station 37 and the control station 38 to arrange. The capsules 1 are delivered as usual, into the capsular segment 22nd inserted, filled, and sealed. In just one revolution of the turntable 21 can single capsules 1 randomly or all capsules 1 as a 100% control then in the weighing device 2 be weighed. After return to the capsular segment 22nd then become the capsules 1 Sorted according to good or bad and ejected at the appropriate stations.
