Description

Technical Field

[0001] The utility model relates to food and medicine production equipment, in particular to a capsule carrier. Background Art

[0002] Capsules have many advantages and are widely used in the pharmaceutical industry. Capsules contain a fixed amount of drugs with accurate dosages. For some powders or granules that are irritating to the esophagus and gastric mucosa, or drugs that are radioactive, have a bad taste, are easy to volatilize, are easily decomposed by saliva in the mouth, and are easily inhaled into the trachea, capsules can be used to wrap them, which not only protects the medicinal properties of the drugs from being destroyed, but also protects the digestive organs and respiratory tract, ensuring the efficacy of the drugs while preventing drug waste. At present, in the process of capsule pharmaceutical production, semi-automatic mechanisms are usually used to first load the upper and lower capsules of the capsule into the upper and lower plates of the capsule respectively, and then manually fill the drugs and then manually close the capsules to finally produce the finished capsules. Manual operation is inefficient, labor-intensive, and has a high risk of contamination, especially for some radioactive drugs, which pose a greater safety risk to operators.

[0026] Figures 1 to 4An embodiment of a capsule carrier of the utility model is shown. The capsule carrier of this embodiment includes an upper nest plate 91, a middle nest plate 92 and a lower nest plate 93. An opening and closing guide structure is provided between the upper nest plate 91, the middle nest plate 92 and the lower nest plate 93. The upper nest plate 91 is provided with a limiting portion 912 for limiting the upper capsule, the middle nest plate 92 is provided with a positioning hole 921 for positioning the upper capsule, the lower nest plate 93 is provided with a positioning groove 932 for positioning the lower capsule, and a through hole 933 is provided below the positioning groove 932.

[0027] The capsule carrier of the present embodiment includes an upper nest plate 91, a middle nest plate 92 and a lower nest plate 93. The positioning hole 921 on the middle nest plate 92 and the positioning groove 932 on the lower nest plate 93 are respectively used to position the upper capsule and the lower capsule so that the upper capsule is aligned with the lower capsule up and down. The through hole 933 below the positioning groove 932 facilitates the capsule closing push rod 311 to extend into and lift the lower capsule upward. The limiting part 912 on the upper nest plate 91 is used to limit the upper capsule to prevent the lower capsule from lifting upward and excessively shifting upward when the upper capsule is closed with the upper capsule. The overall structure is simple and low in cost, which is conducive to avoiding dead corners for cleaning and sterilization. The opening and closing process only needs to drive the upper nest plate 91 and the middle nest plate 92 to rise and fall, which is conducive to simplifying the action process and improving production efficiency. By setting an opening and closing guide structure, a guiding effect is provided for the lifting process of the middle nest plate 92 and the upper nest plate 91 to avoid deviation.

[0028] Furthermore, in this embodiment, the upper nest board 91 is provided with an avoidance portion 911 for the middle nest board grabber 34 to pass through, and the middle nest board grabber 34 can directly pass through the avoidance portion 911 to grab the middle nest board 92, and the structure is simple and effective. Preferably, the upper nest board grabber 33 and the middle nest board grabber 34 use suction cups, which can easily grab and release the upper nest board 91 and the middle nest board 92. Of course, in other embodiments, the upper nest board grabber 33 and the middle nest board grabber 34 can also be mechanisms such as clamps; the upper nest board grabber 33 and the middle nest board grabber 34 share the first lifting drive member 32, which can achieve synchronous lifting and simplifying the structure. Of course, in other embodiments, the upper nest board grabber 33 and the middle nest board grabber 34 can also be respectively arranged on a first lifting drive member 32. Among them, the first lifting drive member 32 can be, for example, a cylinder, an electric cylinder, a lifting slide, etc.

[0029] Furthermore, in this embodiment, the opening and closing guide structure includes a guide column 94 provided on the lower nest plate 93 and a guide hole 95 provided on the upper nest plate 91 and the middle nest plate 92. The cooperation between the guide column 94 and the guide hole 95 is conducive to aligning the middle nest plate 92, the upper nest plate 91 and the lower nest plate 93 up and down, and at the same time provides a guiding effect for the lifting process of the middle nest plate 92 and the upper nest plate 91 to avoid deviation.

[0030] As a preferred embodiment, two guide posts 94 are provided and arranged along the diagonal line of the lower nesting plate 93, which can effectively prevent the middle nesting plate 92 and the upper nesting plate 91 from deflecting during the lifting process.

[0031] Furthermore, in this embodiment, the capsule carrier also includes a mobile platform 2, and a lower nest plate positioning portion 21 is provided on the mobile platform 2. The lower nest plate 93 can be placed on the lower nest plate positioning portion 21, and then the capsule carrier 9 can be driven by the mobile platform 2 to move between the opening and closing mechanism 3, the filling device 4 and other components, so that the opening and closing mechanism 3, the filling device 4 and other components only need to move up and down, and do not need to move horizontally, which is conducive to simplifying the structure and further reducing costs.

[0032] As a preferred embodiment, convex parts 22 are provided on opposite sides of the lower nest plate positioning part 21, and slide grooves 931 for cooperating with the convex parts 22 are provided on opposite sides of the lower nest plate 93. Through the cooperation between the slide grooves 931 and the convex parts 22, it is convenient to accurately insert the capsule carrier 9 into the positioning part 21, and prevent the lower nest plate 93 from being lifted upward during the process of opening and closing the capsule, and the structure is simple and effective.

[0033] As a preferred embodiment, a guiding inclined surface 23 is provided on one side of the lower nest plate positioning portion 21 to facilitate the lower nest plate 93 to be inserted into the lower nest plate positioning portion 21 along the guiding inclined surface 23 .

[0034] Furthermore, in this embodiment, the lower nest plate positioning part 21 is provided with a passage (not shown in the figure) for the capsule closing push rod 311 to pass through. After the filling is completed, the mobile platform 2 drives the lower nest plate 93 to return to the opening and closing mechanism 3, and the opening and closing mechanism 3 drives the upper nest plate 91 and the middle nest plate 92 to descend to their positions, and then the second lifting drive member 312 drives the capsule closing push rod 311 to rise, and after the capsule closing fixed rod 311 passes through the through hole 933, the positioning groove 932 and the passage of the lower nest plate positioning part 21, the lower capsule is lifted upward and combined with the upper capsule as a whole, and the limiting part 912 of the upper nest plate 91 can limit the upper capsule to prevent the upper capsule from excessively shifting upward when the lower capsule is lifted upward and closed with the upper capsule, and the structure is simple, effective and efficient. Among them, the second lifting drive member 312 can be, for example, a cylinder, an electric cylinder, a lifting slide or a screw nut mechanism.

[0035] Furthermore, in this embodiment, a first step portion for preventing the upper capsule from falling is provided in the positioning hole 921, and a second step portion for preventing the lower capsule from falling is formed between the positioning groove 932 and the through hole 933. That is, the first positioning hole 921 is a stepped hole structure with a large upper section and a small lower end, and the diameter of the through hole 933 is smaller than the diameter of the positioning groove 932, which is conducive to preventing the upper and lower capsules from shifting and falling, and the overall structure is simple and effective.

[0036] The method for preparing a capsule using the capsule carrier comprises the following steps:

[0037] S1, loading: the capsule carrier 9 is transferred to the lower nest plate positioning portion 21 on the mobile platform 2 (specifically, the lower nest plate 93 in the capsule carrier 9 is moved to the lower nest plate positioning portion 21), which can be referred to Figure 4 (a);

[0038] S2, filling: the upper nest plate grabbing member 33 and the middle nest plate grabbing member 34 descend to grab the upper nest plate 91 and the middle nest plate 92 respectively, and then rise to separate the upper capsule from the lower capsule, and the mobile platform 2 drives the lower nest plate 93 to move to the bottom of the filling device 4 (for example, it can be a pipette or a filling needle, etc.), and the lower capsule moves with the lower nest plate 93 to the bottom of the filling device 4, and the filling device 4 descends to fill the medicine into the lower capsule, as shown in the following figure. Figure 4 (b) and Figure 4 (c)

[0039] S3, closing the bag: the mobile platform 2 drives the lower nesting plate 93 to return to the opening and closing mechanism 3, the upper nesting plate grabbing member 33 and the middle nesting plate grabbing member 34 are lowered, and the closing bag top rod 311 rises to make the lower bag rise and combine with the upper bag. Figure 4 (d) and Figure 4 (e) as shown.

[0040] The capsule preparation method has a high degree of automation, a simple preparation process and high production efficiency.
