Description

Technical Field

[0001] The utility model belongs to the technical field of capsule filling equipment, and in particular relates to a station turntable assembly for automatic capsule filling. Background Art

[0002] A capsule filling machine is a specialized device used to prepare medication capsules. Its principle is to use a series of mechanical devices and control systems to fill empty capsule shells with drug powder or liquid for patient administration. The capsule filling machine can complete the processes of capsule dispensing, drug filling, sealing, rejecting, and discharge. Its operating principle is that a rotating turntable is equipped with stations corresponding to each production step. Each station is equipped with a mold on the outer side of the turntable. The molds are generally divided into upper and lower molds, which are fully aligned with their internal mold holes. The molds rotate to the corresponding station, and the equipment at that station completes the corresponding operation.

[0003] When the mold moves to the drug filling station, the upper and lower molds are offset, and the lower mold carries the capsule body to the bottom of the drug filling equipment, completing the capsule filling operation. The upper and lower molds are then fully aligned to complete the next step of resealing the capsule cap and capsule body. The lower mold is controlled by the drive assembly to move it away from or align with the upper mold. However, if the drive assembly fails, causing the lower mold to move out of position, the upper and lower molds may not align completely. If the incomplete alignment of the upper and lower molds is not discovered and corrected in time, the capsule cap and capsule body will also not align completely. This will harden the seal between the capsule body and the capsule cap, causing the capsule to be scrapped. Utility Model Content

DETAILED DESCRIPTION

[0058] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0059] Example 1

[0060] A turntable assembly for automatic capsule filling, comprising: a supporting plate 1, a turntable 2, a turntable drive assembly, an upper mold 1501, a lower mold 1502, a lower mold drive assembly, and a mold alignment monitoring assembly;

[0061] like Figure 1 As shown, the support plate 1 serves as a supporting structure for the turntable 2. The entire turntable 2 is located above the support plate 1 and can rotate relative to the support plate 1. The turntable 2 is controlled to rotate by a turntable drive assembly, which includes: a motor, a rotating shaft, a rotating shaft channel 102, and a rotating shaft slot 201.

[0062] The motor is arranged below the supporting plate 1, and a rotating shaft is connected to the rotor of the motor, and the rotating shaft can rotate along with the motor;

[0063] The shaft channel 102 is opened at the center position of the support plate 1; the shaft can pass through the shaft channel 102; a shaft groove 201 is set at the center position of the turntable 2, the entire shaft groove 201 is located in the turntable 2, and the upper end of the shaft groove 201 is closed, and the lower end opening of the shaft groove 201 is set on the bottom surface of the turntable 2; after the shaft passes through the shaft channel 102, the shaft is fixedly connected to the shaft groove 201; the motor drives the shaft to rotate, and the shaft drives the turntable 2 to rotate.

[0064] The turntable 2 rotates on the supporting plate 1, and the lower surface of the turntable 2 will inevitably contact with the upper surface of the supporting plate 1, generating friction. The friction between the two will affect the smoothness of the rotation of the turntable 2. In order to minimize the friction resistance of the turntable 2 when rotating on the supporting plate 1, as shown in FIG. Figure 3 As shown, an annular ball chute is provided on the upper surface of the support plate 1, into which a plurality of balls 101 are movably embedded, allowing the balls 101 to roll freely. The balls 101 are not completely embedded in the chute, but are partially exposed. An annular upper ball chute 202 is provided on the lower bottom surface of the turntable 2, directly opposite the chute. When the turntable 2 is placed above the support plate 1, the portion of the balls exposed from the chute just movably fits into the upper ball chute 202. In this way, when the turntable 2 rotates relative to the support plate 1, the frictional force experienced by the turntable 2 can be reduced under the action of the balls 101, making the turntable 2 rotate more smoothly.

[0065] In the capsule filling equipment, the turntable 2 serves as a transfer device. The capsule placing device, filling device, and waste rejection device are arranged on the outer periphery of the turntable 2. Several workstations are set on the outer wall of the turntable. Different processing operations are performed at different workstations. The mold rotates to the corresponding workstation, and the device at the corresponding workstation performs the corresponding operation.

[0066] like Figure 1As shown, twelve workstations are set at equal intervals on the outer wall of the turntable 2, and a group of molds 15 are set at each workstation. A group of molds 15 includes an equal upper mold 1501 and a lower mold 1502. A number of mold holes 1503 are opened inside each group of molds 1, and the mold holes 1503 pass through the upper and lower surfaces of the upper mold 1501 and the lower mold 1502. The mold holes 1503 in the upper and lower molds can correspond to each other one by one; the mold 15 can rotate with the turntable 2. When the mold 15 rotates to the corresponding workstation position, the equipment will perform corresponding processing; the capsule sowing device sows the empty capsule shells into the mold holes 1503 at the capsule sowing station, and always keeps the capsule cap facing upward. At this time, the capsule cap is partially located in the mold hole 1503 of the upper mold 1501 The mold 15 then rotates. Before reaching the drug filling station, the capsule cap and the capsule body of the capsule shell need to be separated. A vacuum will be generated on the lower bottom surface of the lower mold 1502. The capsule body will be separated from the capsule cap through vacuum adsorption, and the capsule cap will be stuck in the mold hole 1503 of the upper mold 1501. When arriving at the drug filling station, the lower mold 1502 is separated and staggered from the upper mold 1501 by moving. The lower mold 1502 carries the capsule part in the mold hole 1503 to the bottom of the drug filling device, and the drug is filled into the capsule. Then the lower mold 1502 moves again to completely align with the upper mold 1501, and the capsule cap and the capsule body filled with the drug are sealed by the sealing device, thus completing the production of a capsule drug.

[0067] Therefore, the lower mold 1502 needs to be movable relative to the upper mold 1501, that is, it can be translated in the direction away from the upper mold 1501 to achieve separation and staggering of the two; it can also be translated in the direction close to the upper mold 1501 to achieve complete alignment of the two; the lower mold 1502 is controlled by the lower mold driving assembly; Figure 2 As shown, the above-mentioned lower mold driving assembly includes: a cylinder 16 and a telescopic rod 17;

[0068] The cylinder 16 is provided inside the turntable 2; one end of a telescopic rod 17 is movably provided on the cylinder 16, and the other end of the telescopic rod 17 passes through the side wall of the turntable 2 and is provided on the lower mold 15;

[0069] The cylinder 16 drives the telescopic rod 17 to extend or retract, thereby controlling the lower mold 1502 to move away from or close to the upper mold 1501, thereby achieving misalignment of the lower mold 1502 and the upper mold 1501 or achieving complete alignment of the lower mold 1502 and the upper mold 1501.

[0070] The cylinder 16 and the telescopic rod 17 controlled by the cylinder 16 belong to the prior art, and the detailed structure and working principle thereof will not be described in detail here.

[0071] The lower mold 1502 is separated from the upper mold 1501 and staggered. After the capsule in the lower mold 1502 is filled with the medicine, the lower mold 1502 needs to be fully aligned with the upper mold 1501 again. However, in actual production, the cylinder 16 may malfunction, causing the telescopic rod 17 to not move into place, resulting in incomplete alignment of the lower mold 1502 and the upper mold 1501. If the lower mold 1502 and the upper mold 1501 are not fully aligned, it means that the upper capsule cap and the capsule body cannot be fully aligned. When the two are sealed, misalignment occurs, resulting in the capsule being scrapped. Therefore, timely detection of incomplete alignment between the lower mold 1502 and the upper mold 1501 and timely correction can reduce the capsule scrap rate.

[0072] In this embodiment, a mold alignment monitoring component is provided on the upper mold 1501 and the lower mold 1502 to monitor whether the upper and lower molds are aligned completely;

[0073] like Figure 5 As shown, the mold alignment monitoring assembly includes: an embedded column 1504, a semicircular embedded groove 1505 and a patch pressure sensor 1506;

[0074] The embedded column 1504 is set on one side of the lower mold 1502, and the lower bottom surface of the embedded column 1504 is flush with the lower bottom surface of the lower mold 1502; when the upper and lower molds are completely matched, the upper surface of the embedded column 1504 is flush with the upper surface of the upper mold 1501; a semicircular embedded groove 1505 is set on the same side of the upper mold 1501, and after the embedded column 1504 is placed in the semicircular embedded groove 1505, the outer wall of the embedded column 1504 can be completely fitted on the inner wall of the semicircular embedded groove 1505, and the inner wall of the semicircular embedded groove 1505 is set A patch pressure sensor 1506 is provided, and the patch pressure sensor 1506 is communicatively connected to the PLC. When the upper mold 1501 and the lower mold 1502 are completely aligned, the embedded column 1504 can be fully fitted into the semicircular embedded groove 1505 and exert pressure on the inner wall thereof. At this time, the patch pressure sensor 1506 will collect a pressure value that meets the requirements and feed it into the PLC. The PLC determines that the upper mold 1501 and the lower mold 1502 are completely aligned based on the pressure information of the embedded column 1504 on the semicircular embedded groove 1505.

[0075] If the upper mold 1501 and the lower mold 1502 are not completely aligned, the embedded column 1504 is not completely fitted in the semicircular embedded groove 1505, and the pressure generated is too small; or even the embedded column 1504 does not touch the inner wall of the semicircular embedded groove 1505 at all, and the pressure value cannot be collected at this time; it means that the upper mold 1501 and the lower mold 1502 are not completely aligned. The PLC determines which workstation mold is not completely aligned based on the pressure signal source and issues an alarm prompt so that the staff can deal with it in time.

[0076] Example 2

[0077] Based on Example 1, in this embodiment, the alignment monitoring components provided include: an infrared light source 1507 and an infrared signal receiver 1508;

[0078] The infrared light source 1507 is centrally arranged on the lower bottom surface of the upper mold 1501, and the infrared light source 1507 is flush with the lower bottom surface of the upper mold 1501; the infrared signal receiver 1508 is arranged on the upper surface of the lower mold 1502, and the infrared signal receiver 1508 is flush with the upper surface of the lower mold 1502; when the upper mold 1501 and the lower mold 1502 are completely aligned, the infrared light source 1507 is facing the infrared signal receiver 1508; the infrared signal receiver 1508 is connected to the PLC for communication.

[0079] When the upper mold 1501 and the lower mold 1502 are fully aligned, the infrared signal receiver 1508 can normally receive the infrared signal emitted by the infrared light source 1507. After receiving the light signal, the infrared signal receiver 1508 will feed the received signal to the PLC, and the PLC will then determine that the lower mold 1501 and the upper mold 1502 are fully aligned. Conversely, if the infrared signal receiver 1508 cannot receive the infrared light signal emitted by the infrared light source 1507, it means that the lower mold 1502 and the upper mold 1501 are not fully aligned. The PLC will determine which infrared signal receiver 1508 at which station is not receiving the signal and issue an alarm prompt so that the staff can deal with it in time.

[0080] Example 3

[0081] Based on Example 1, the capsule cap and capsule body are separated by generating a vacuum under the lower mold 1502, which creates a vacuum suction effect on the capsule body, thereby separating the capsule body and the cap. During the separation process, the capsule cap is stuck in the upper mold 1501. However, in actual production, a small amount of the capsule cap may not be stuck in the upper mold 1501 and move with the capsule body, resulting in the capsule cap and capsule body being unable to be separated smoothly.

[0082] So, if Figure 7 As shown, in this embodiment, an elastic bag 1509 is provided on the side wall of the mold hole opened in the upper mold 1501; the elastic bag 1509 and the side wall of the mold hole 1503 in the upper mold 1501 form a cavity. When the cavity is not inflated, the elastic bag 1509 is attached to the side wall of the mold hole 1503 in the upper mold 1501;

[0083] Each cavity is connected to one end of a branch channel disposed within upper mold 1501. The other ends of the branch channels converge into a main ventilation tube 1511 disposed on the sidewall of upper mold 1501. Air is inflated through main ventilation tube 1511 into the branch channels, and the air flows through the branch channels into the corresponding cavities, inflating elastic bladder 1509. The inflated elastic bladder 1509 clamps the bladder cap, allowing for smooth separation of the bladder body and cap.

[0084] Example 4

[0085] Based on Example 3, in Example 3, the elastic bag 1509 is propped up by inflating the cavity, thereby clamping the bag cap; however, the amount of gas filled is difficult to control; if too little is filled, the elastic bag 1509 is not fully propped up, and the clamping effect on the bag cap is insufficient; and if too much is filled, the clamping force is too large, which may cause the bag cap to deform.

[0086] like Figure 8 As shown, in this embodiment, the interior of the upper mold 1501 is configured as a hollow structure; a plurality of through holes 1510 are evenly distributed on the side walls of the mold hole opened in the upper mold 1501; the through holes 1510 are connected to the hollow structure inside the upper mold 1501; a ventilation trunk pipe 1511 is provided on the side wall of the upper mold 1501; one end of the ventilation trunk pipe 1511 is connected to the hollow structure inside the upper mold 1501. The ventilation trunk pipe 1511 is connected to a vacuum pump; the vacuum pump creates a vacuum environment in the hollow structure inside the upper mold 1501, and the capsule cap is adsorbed on the side wall of the mold hole 1503 in the upper mold 1501 through the through holes 1510, thereby achieving the function of fixing the capsule cap;

[0087] The even distribution of the through holes 1510 on the side wall of the die hole can ensure that the vacuum adsorption effect on the outer wall of the capsule cap is evenly distributed, so that the outer wall of the capsule cap can be evenly adsorbed and fit on the side wall of the die hole 1503.
