Description

Technical Field

[0001] The present invention relates to a tablet arranging and supplying device for arranging and transferring tablets for inspecting the quality of tablets or packaging tablets on a tablet production line such as tablets or capsule drugs, and more particularly to a tablet arranging and supplying device that can prevent tablets placed in the arranging grooves of rollers from detaching from the arranging grooves and stably transfer them. Background Art

[0002] The types of drugs manufactured by pharmaceutical companies are diverse, and according to the dosage form of the drugs, they can generally be classified into aqueous solutions, granules, tablets, or capsule (soft capsule) drugs.

[0003] At this time, for tablets such as tablets or capsules, individual inspections are carried out in real time during each production process, so that defective tablets are recovered in real time during the production process and re-produced or discarded. In addition, good-quality tablets are packaged.

[0004] The tablet arranging and supplying device inspects and packages tablets by arranging and transferring the tablets.

[0005] In the registered patent No. 10-2310235 "Visual inspection device for tablets", the tablets are arranged and transferred by placing the tablets in the placement part of the circulating rollers.

[0006] In the registered patent No. 10-2310235 "Visual inspection device for tablets", there is no component for guiding the tablets input onto the rollers to be placed in the placement part, so there may be tablets transferred to a position other than the placement part, an idle placement part without tablets placed, and tablets overlapping and placed on one placement part. When the above situations occur, it will lead to a decrease in the accuracy of the inspection of good-quality tablets and a reduction in the speed of the inspection or packaging of good-quality drugs.

[0032] Next, the tablet arranging and supplying device according to the present invention will be described in more detail with reference to the accompanying drawings.

[0033] As shown in the figure, the tablet arranging and supplying device according to the present invention includes a plurality of rollers 10, a circulation component 20, a supply hopper 30, brushes 41, 42, and a reverse rotation assembly 51, 52.

[0034] A plurality of the rollers 10 are continuously arranged and circulated for transfer.

[0035] Refer to Figure 3 , shaft projections 11 rotatably coupled to the circulation component 20 are formed at both ends of the roller 10, a placement groove 13 for placing the tablet 1 is formed at the central portion, and a pressing part 15 pressed by the pressing plate 51 of the reverse rotation assembly 51, 52 or the circulation pressing belt 52 is formed at the edge.

[0036] The tablet 1 is placed in the placement groove 13 between two rollers 10 for transfer. In addition, the roller 10 can rotate about the shaft projection 11 during the circulation transfer, so that the tablet 1 placed in the placement groove 13 rotates 360 degrees. Thereby, the overall surface quality of the tablet 1 can be inspected. For reference, the quality inspection of the tablet 1 inspects for bubbles, shape, size, characters, and foreign matters, etc.

[0037] The circulation component 20 circulates and transfers the rollers 10.

[0038] The circulation component 20 may be composed of a chain 21 or a timing belt, a gear 23 meshing with both sides of the chain 21 or the timing belt, and an electric motor for rotating the gear 23.

[0039] The supply hopper 30 supplies the tablets 1 to the upper part of the rollers 10 that are circulated for transfer.

[0040] Connected to the supply hopper 30 is a discharge port 31 for discharging the tablets 1 to the upper part of the rollers 10, and a regulator for adjusting the number of the discharged tablets 1 may be provided at the lower part of the supply hopper 30.

[0041] The brushes 41 and 42 are provided at the upper part of the rollers 10 that are circularly transferred, so as to guide the tablets 1 to be placed in the placement grooves 13 of the rollers 10 and remove the tablets other than one of the tablets 1 that are overlapped and placed in the placement grooves 13.

[0042] The brushes 41 and 42 may be composed of a first brush 41 arranged at the front side of the rollers 10 that are circularly transferred and a second brush 42 arranged at the rear side.

[0043] The first brush 41 and the second brush 42 are combined into a rectangular frame 45 that is open at the upper and lower parts.

[0044] The first brush 41 and the second brush 42 may be fixedly combined into the rectangular frame 45 or may be combined in a rotatable manner.

[0045] When the first brush 41 and the second brush 42 are combined with the rectangular frame 45 in a rotatable manner, it is advisable to rotate them in a direction opposite to the circular transfer direction of the rollers 10 by means of a motor.

[0046] The end of the first brush 41 is separated from the surface of the roller 10 by a first gap.

[0047] Among them, the first gap is a spacing smaller than the thickness of the tablet 1.

[0048] The tablets 1 placed on the surface of the roller 10 rather than in the placement grooves 13 will be blocked by the first brush 41 and cannot pass through, and the tablets 1 blocked by the first brush 41 will move to the side and be placed in the placement grooves 13 of the roller 10.

[0049] The end of the second brush 42 contacts the surface of the roller 10 or is separated from the surface by a second gap.

[0050] Among them, the second gap is a spacing smaller than the first gap.

[0051] When two or more tablets 1 are placed in one placement groove 13, a part of another tablet 1 (overlapping tablet) will overlap above the tablet 1 (central tablet) placed deep in the center of the placement groove 13 between the two rollers 10, so that the overlapping tablet is higher and more convex than the central tablet.

[0052] The second brush 42 can separate and remove the higher and more convex overlapping tablet by blocking it from the placement groove 13.

[0053] The reverse rotation components 51 and 52 can cause the rollers in the arrangement area where the brushes 41 and 42 are located to rotate in the direction opposite to the circulation transfer direction, thereby preventing the tablets 1 from detaching from the placement grooves 13. In particular, it is possible to prevent the central tablet 1 from detaching from the placement groove 13 during the process of the second brush 42 removing the central tablet 1.

[0054] Since the overlapping tablets 1 are in contact with the central tablet 1, the impact generated during the process of removing the overlapping tablets 1 from the placement groove 13 by the second brush 42 may be transmitted to the central tablet 1, causing the central tablet to separate and detach from the placement groove 13.

[0055] By causing the rollers 10 to rotate in the direction opposite to the circulation transfer direction, the two rollers 10 can more powerfully restrain the tablets 1 placed in the placement grooves 13, thereby preventing them from separating and detaching from the placement grooves 13.

[0056] As the reverse rotation components 51 and 52, a pressure plate 51 or a circulating tight belt 52 can be used.

[0057] The pressure plate 51 is provided at the lower part of the rectangular frame 45 to press the surface of the pressing portion 15 formed at the edge of the roller 10.

[0058] Refer to Figure 5 , when the pressure plate 51 presses the upper surface of the roller 10, the roller 10 will rotate in the direction opposite to the circulation transfer direction.

[0059] The circulating tight belt 52 is provided inside the rollers 10 that are circulated and transferred, and circulates and transfers in a state of being in close contact with the surface of the pressing portion 15 formed at the edge of the roller 10.

[0060] Refer to Figure 6 , the circulating tight belt 52 circulates and transfers in the same direction as the circulation transfer direction of the roller 10, and since the circulation transfer speed of the circulating tight belt 52 is relatively faster than the circulation transfer speed of the roller 10, the roller 10 with its lower surface in close contact will rotate in the direction opposite to the circulation transfer direction.

[0061] In the above process of explaining the present invention, a tablet arrangement and supply device with a specific shape and structure has been described with reference to the drawings. However, the present invention can be variously deformed and changed by relevant practitioners, and the above-described deformations and changes should all be interpreted as being included within the protection scope of the present invention.
