The foregoing and other features, aspects and advantages of the disclosed embodiments will become more apparent from the following detailed description and accompanying drawings.
In the following, preferred embodiments of the storage container according to the disclosure and the storage and dispensing station according to the disclosure are described with reference to the accompanying drawing, in which:
The detailed description set forth below describes various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. Accordingly, dimensions are provided in regard to certain aspects as non-limiting examples. However, it will be apparent to those skilled in the art that the subject technology may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology.
It is to be understood that the present disclosure includes examples of the subject technology and does not limit the scope of the appended claims. Various aspects of the subject technology will now be disclosed according to particular but non-limiting examples. Various embodiments described in the present disclosure may be carried out in different ways and variations, and in accordance with a desired application or implementation.
Modern blister machines, as disclosed, for example, in WO 2013/034504 A1, comprise several hundred storage and dispensing stations, depending on the level of expansion of the blister machine. A plurality of separable small piece goods are stored in each of these, and individual small piece goods can be dispensed on demand. The small piece goods are regularly drug portions and food supplement portions.
With blister machines, for example, drug portions stored in the storage and dispensing stations can be combined and blistered individually for each patient according to the medically prescribed intake times. To put together a plurality of drug portions, appropriate storage and dispensing stations for dispensing one or more drug portions are controlled by means of a control device of the blister machine. In order to dispense a drug portion, a drug portion stored in a storage container is separated with a separating device of the storage and dispensing station and transferred via a dispensing opening to a guide device of the blister machine. With the aid of the guide device, the dispensed drug portion, optionally by interposing a collecting device, is fed to a packaging device, which blisters individual or a plurality of drug portions.
For the separation of the drug portions stored in a storage container of a storage and dispensing station, the separating device comprises a plurality of channels, which are usually arranged on the outer circumference of a base body of the separating device. The channels are adjusted to the respective drug portions to be separated with regard to their dimensions such that the drug portions can only be arranged one above the other, but not adjacent to one another, in a channel. The channels may, for example, be dimensioned in such a way that only one drug portion may be received in one channel.
To dispense a drug portion from a channel, a channel is moved over the dispensing opening in the bottom surface of the housing of the storage container, and the drug portion arranged in the channel (at the lowest point) slides or falls due to gravitational force into the dispensing opening. In order to prevent additional drug portions stored in or above the channel from also being dispensed, i.e., an unknown number of drug portions from being dispensed, in the region above the dispensing opening a retaining portion of a retaining means or separator is guided or arranged at least in or above the channel that is aligned with the dispensing opening. The retaining portion is arranged in or above the channel with respect to the height of the channel in such a way that only one drug portion may be arranged under the retaining portion. If the retaining portion is guided into the channel to separate the lowermost drug portion from those arranged above it, individual channel-separating projections have a slot which receives the retaining portion. If the retaining portion is arranged or guided over the channels, it is guided routinely only slightly over the upper ends of the projections to avoid additional drug portions from entering the channel when the drug portion is dispensed.
When separating or dispensing drug portions, the separating device is rotated as described above. Thereby the drug portions stored in the receiving space are constantly moved, which leads to friction between the drug portions and on the housing. This friction with one another and on the housing leads to the drug portions being charged by frictional electricity, which means that the drug portions are electrostatically charged. This electrostatic charge leads to the drug portions partially “sticking” to the inner wall of the housing or to portions of the separating device. On the one hand, this leads to the fact that not the number of drug portions that are filled into the storage container is actually available for separation (because the drug portions “stick” somewhere inside) or that the drug portions are not correctly dispensed, both of which cases lead to incorrect drug combinations.
It is therefore the object of the present disclosure to provide a storage container for a storage and dispensing station for a blister machine, with which an electrostatic charge of small piece goods can be reduced during the separation thereof
The storage container according to the disclosure for a storage and dispensing station for a blister machine, comprises a housing enclosing a receiving space having an inside circular-cylindrical portion and having a bottom surface having a dispensing opening, a separating device arranged in the inside circular-cylindrical portion of the housing and having a surface facing the receiving space and having a plurality of channels extending vertically through the separating device having a channel width for receiving at least one small piece good to be separated, and a retaining means having a retaining portion which is arranged above the dispensing opening in the circular-cylindrical housing.
According to the disclosure, it is provided that the separating device comprises an electrically dischargeable discharging device, the discharging device having at least one discharging projection extending from the surface of the separating device into the receiving space as well as a discharging contact means coupled in an electrically dischargeable manner to the at least one discharging projection for electrically coupling the discharging device to an electrically dischargeable component of a dispensing station which is assigned to the storage container and has a drive.
With the discharging device reaching into the receiving space, the electrostatic charge of the small piece goods caused by the friction is discharged via the discharging contact means into the dispensing station, the electrostatic charge of the small piece goods is reduced or even (largely) minimized or discharged, whereby the above-mentioned effects are avoided—the small piece goods do not adhere to the inner wall or parts of the separating device, incorrect combinations are avoided. The discharging device is continuously electrically dischargeable from the discharging projection to the discharging contact, although this does not have to mean that the entire discharging device as such has to be made of electrically dischargeable material—portions can, for example, be sheathed or otherwise surrounded by non-electrically dischargeable material. An electrically dischargeable material is considered to be one whose discharge resistance (surface resistance) is less than 1 TΩ (1012 Ω).
The fact that the discharging device has at least one discharging projection that extends into the receiving space ensures that the electrostatic charge is reduced in the small piece goods arranged “further up” so that sticking to the inner wall can be prevented. This ensures that all of the small piece goods filled into the receiving space are also available for separation and dispensing. The electrical discharge in the upper region of the receiving space also ensures that the small piece goods entering the channels have a reduced electrostatic charge.
The precise structural design of the discharging device, and in particular the electrically dischargeable connection between discharging projection and the discharging contact means, depends on the precise design of the separating device. In the case of a structurally very simple (and thus cost-effective form), it is provided that the discharging projection and the discharging contact means are designed as a discharging rod having a central connecting portion.
As described above, it is substantial for the disclosure that the discharging contact means of the discharging device is electrically couplable to an electrically conductive component of a dispensing station which is assigned to the storage container and has a drive. In one or more embodiments of the storage container according to the disclosure, it is provided that the discharging contact means is formed coaxially to (and preferably on) the axis of rotation of the separating device. With a corresponding design of the discharging contact means, it can be electrically coupled to a component of the drive of the dispensing station; the discharging contact means virtually “sits” on the component of the drive (in which case this component must of course be electrically dischargeable and the charges must be able to be diverted via the dispensing station).
In particular, when the discharging contact means is formed coaxially to the axis of rotation of the separating device, it is further advantageous if the discharging contact means is designed as a discharging pin which has a contact pin pretensioned by a spring. Since the contact pin is pretensioned by means of a spring, the contact between the discharging device and the dispensing station is particularly supported.
The discharging projection of the discharging device protrudes into the receiving space, so that in particular the electrostatic charge of those small piece goods that are arranged above the surface of the separating device is reduced. In order to ensure or strengthen the discharge of any electrostatic charge that may still be present or that has built up again from small piece goods arranged “further down,” it is provided in one or more embodiments of the storage container according to the disclosure that the discharging device has at least one discharging means coupled in an electrically dischargeable manner to the discharging contact means which discharging means forms a surface region of the separating device which comes into contact with small piece goods.
As explained above, the electrostatic charging of small piece goods can also cause them to get stuck in a channel (on the channel wall). The discharging projection already reduces the charging of the small piece goods, but to further reduce the charge directly before small piece goods enter a channel, one or more embodiments provides that the at least one discharging means forms at least one portion of a surface of a web formed between two channels. A corresponding embodiment is particularly advantageous for very light small piece goods (since these tend to stick or “adhere” even when they are only slightly charged).
The disclosure also relates to a storage and dispensing station for a blister machine, comprising a storage container according to the disclosure and a dispensing station having a drive for moving the separating device and having a dispensing station contact means which is designed to be electrically couplable to the discharging contact means of the discharging device of the storage container and is coupled to a conduction device in an electrically dischargeable manner via which electrical charges can be diverted from the storage and dispensing station. In one or more embodiments, it is provided that the dispensing station contact means is designed as a coupling means of the drive.
As may be seen in
As already explained above, the channels 32 are adjusted to the shape of the drug portions to be separated so that only a defined number can be arranged in a channel 32 or in a channel portion. As can be seen from
In the sectional views of
At the other end of the discharging device 50, the discharging device 50 includes a discharging contactor 53, which may be rod-shaped. The discharging contactor 53 is connected to the discharging projection 51 in an electrically dischargeable manner, wherein, in the simplest case as shown here, the discharging projection 51 and the discharging contactor 53 are designed as a one-piece rod that is formed coaxially with or on the axis of rotation of the separating device 30. The discharging device 50 may be made of stainless steel, or in general, any dischargeable material (see above for definition) is suitable as long as there is a dissipative connection between the discharging projection 51 and the discharging contactor 53.
In aspects of the disclosure, it is conceivable that the retaining portion 41 is guided in a slot (not shown) of the webs 33 between the channels 32, wherein the slot or retaining portion 41 separates a channel 32 into an upper and a lower channel portion (not shown). Which type of channel 32 is used depends on the drug portions to be separated and has no effect on the present disclosure.
In aspects of the disclosure, the dispensing station 100 is part of a network of five dispensing stations 100. In aspects of the disclosure, the dispensing stations 100 can be designed separately from one another. The components mentioned in the following description of the dispensing station 100 are present in each dispensing station 100, regardless of whether they are configured as a composite (as in
Each dispensing station 100 includes a lower portion 130 and an upper portion 120. The upper portion 120 includes a projection 121 on which a storage container 1 can be placed. For this purpose, a lower housing portion of the storage container 1 is adjusted to the geometry of the projection 121. The projection 121 includes an opening 123 which, when the storage container 1 is attached, is aligned with the dispensing opening 22 in the bottom surface 20 of the housing 10. In the event of separation, a drug portion falls from a channel 32 via the dispensing opening 22—into the opening 123.
In the case of an end face 122, 132 formed from a housing part of the upper portion 120 and the lower portion 130, the dispensing station 100 can be attached to a blister machine (not shown). In the aforementioned end face 122, 132, an opening 140 is shown, which extends through the dispensing station 100 and ends in the opening 123, a chute (not shown) for drug portions being insertable into these openings 140, via which separated drug portions from a storage and dispensing station 101 are passed to a guide device within the blister machine. The chute extends through the dispensing station 100 up to the projection 121 in which the opening 123 for receiving a drug portion is formed.
In the aforementioned end face 122, 132 of the dispensing station 100 (only in
In aspects of the disclosure, a dispensing station contact, which is substantial to the disclosure, is designed as a coupler 152 of the drive 150. Said coupler 152 is coupled to the conduction device 124 (not shown in
In aspects of the disclosure, the discharging device 50 is coupled to the conduction device 124 via the axis of rotation 151 of the drive 150, via which the charge is ultimately transferred from the storage and dispensing station 101 to the blister machine. In aspects of the disclosure, many other couplings between the storage container 1 and the dispensing station 100 are conceivable. The illustrated case is, however, structurally simple and there is the possibility of simply retrofitting existing dispensing stations 100.
In aspects of the disclosure, the discharging device 50 further includes two discharging members 55, which are connected in an electrically dischargeable manner to the central discharging rod 56, specifically via connecting portions 54. The discharging device 50 is therefore constructed quite simply and can subsequently be introduced into already existing separating devices 30 without considerable effort.
