Description

Technical Field

[0001] The present invention relates to the technical field of capsule production devices, and in particular to a capsule filling sorting device and a use method thereof. Background Art

[0002] The capsule filling machine is used to add powder to hard capsules. Its typical structure includes the following six processes: capsule placement, capsule separation, powder addition, waste rejection, locking, and capsule removal. Capsule separation is as follows: Under the vacuum suction of the hard capsule filling machine, the capsule caps are separated (at this time, the body caps are put together by the pre-locking point, and the tightness is small), and placed in the corresponding modules of the body caps of the capsule filling machine. Locking is as follows: After the capsule is filled with powder, the body cap returns to the station to be fitted again, and the body cap is locked by the filling machine's mechanical ejector and fitting baffle. In this way, a complete hard capsule filled with medicine completes the filling process.

[0003] However, before filling the capsules, the capsules must be sorted first. Existing capsule sorting devices usually arrange the capsules one by one, and have a high error rate. They are not suitable for sorting a large number of capsules, which seriously restricts the efficiency of subsequent capsule processing. Summary of the invention

[0004] In order to solve the above problems in the prior art, a capsule filling sorting device and a method of using the same are provided.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] The present invention proposes a sorting device for capsule filling, comprising a tray, wherein the tray is provided with a plurality of drop-out openings, and the upper surface of the tray is provided with a plurality of evenly distributed pits, the number of the pits is the same as the number of the drop-out openings, the pits are arranged directly above the drop-out openings, and the pits are communicated with the drop-out openings; the tray is also slidably connected to a support rod arranged in a horizontal direction, one end of the support rod is arranged in the pit, a lifting rod is also arranged in the pit, the lifting rod is also connected to a driving mechanism, and the tray is also connected to a vibrator.

[0007] Preferably, the cross section of the lifting rod is an isosceles triangle, the lower surface of the lifting rod is parallel to the upper surface of the tray, and in an initial state, the upper surface of the lifting rod is lower than the upper surface of the support rod.

[0008] Preferably, the driving mechanism comprises an electric push rod arranged in a vertical direction, the lower end of the electric push rod is connected to the lifting rod through a connecting rod, and the electric push rod and the connecting rod are symmetrically arranged on both sides of the tray.

[0009] Preferably, the tray is also provided with a main airway and bronchi, and the bronchi are arranged on both sides of the main airway, and the main airway and the bronchi are communicated with each other; a secondary piston is slidably connected in the bronchus, and one end of the secondary piston close to the pit is fixedly connected to the support rod, and one end of the support rod passes through the bronchus and is slidably set in the pit.

[0010] Preferably, the main air pipe is slidably connected to a main piston, the upper end of the main piston is fixedly connected to a pressure rod, and the pressure rod is arranged directly below the lifting rod.

[0011] Preferably, a pressure block is fixedly connected to the pressure rod, a spring is sleeved on the pressure rod, the upper end of the spring is connected to the lower end of the pressure block, and the lower end of the spring is connected to the tray.

[0012] Preferably, in the initial state, when the spring is in a compressed state, the support rod is slidably disposed in the recess to provide support for the capsule, and the upper surface of the support rod is adapted to the capsule.

[0013] Preferably, the pit is connected to the drop opening via an inclined platform, the width of the drop opening is adapted to the width of the capsule, and the width of the pit is adapted to the length of the capsule.

[0014] Preferably, the tray is also fixedly connected to a plurality of baffles, which are interconnected to form a space for placing capsules.

[0015] The present invention also proposes a method for using a capsule filling sorting device, which uses the above-mentioned capsule filling sorting device and includes the following steps:

[0016] S1: In the initial state, the upper ends of the lifting rod and the pressure rod are in contact, and the spring is in a compressed state, so that one end of the support rod is located in the pit, and the upper surface of the lifting rod is lower than the upper surface of the tray;

[0017] S2: placing the capsule on the tray and starting the vibrator, which drives the tray to vibrate, so that the capsule enters the pit, and the capsule is supported by the support rod;

[0018] S3: Start the electric push rod, which drives the lifting rod to move upward through the connecting rod. The lifting rod drives the capsule to rotate, so that the heavy end of the capsule moves downward. Under the action of the spring, the pressure rod rises, driving the main piston to move upward, so that the secondary piston in the bronchus moves away from the pit;

[0019] S4: As the secondary piston moves, the support rod no longer supports the capsule, and the capsule slides to the drop port via the inclined platform, and then falls from the drop port to the corresponding collection device.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention is provided with a pit for placing capsules. When the vibrator vibrates, the capsule can be driven to fall into the pit. At this time, the support rod is also located in the pit, thereby supporting the capsule. When the lifting rod rises, the capsule will be tilted. Since the big end of the capsule is heavier, the big end of the capsule will be driven to fall downward. The capsule falls into the collecting device through the drop port, thereby completing the sorting of several capsules with high sorting efficiency. By setting a sufficient number of pits, it can be applied to the sorting of large quantities of capsules, and the sorting efficiency is high and the error rate is low, which is beneficial to the subsequent capsule processing.

[0022] 2. The present invention is also provided with a pressure rod. In the initial state, the lifting rod presses the pressure rod downward, driving the main piston to descend, thereby driving the support rod to extend into the pit through the secondary piston, thereby supporting the capsule. When the lifting rod no longer presses the pressure rod, the pressure rod moves upward under the action of the spring, driving the main piston to rise, and the secondary piston drives the support rod to move, so that the support rod no longer supports the capsule. The capsule slides to the drop port via the inclined platform, and falls from the drop port to the corresponding collection device, thereby realizing the automatic dropping of the capsule after sorting.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Reference Figure 1-3 The present embodiment proposes a sorting device for capsule filling, including a tray 4, the tray 4 is provided with a plurality of drop openings 15, the upper surface of the tray 4 is provided with a plurality of evenly distributed pits 18, the number of the pits 18 is the same as the number of the drop openings 15, the pits 18 are arranged directly above the drop openings 15, and the pits 18 and the drop openings 15 are connected.

[0031] Each pit 18 has a corresponding drop opening 15, and the pit 18 is connected to the drop opening 15 through the inclined platform 17. The width of the drop opening 15 is adapted to the width of the capsule 6, and the width of the pit 18 is adapted to the length of the capsule 6. A collecting device is provided below the drop opening to collect the dropped capsules, so as to facilitate the subsequent processing of the capsules.

[0032] Specifically, the pit 18 is slightly wider than the length of the capsule 6 , and the drop opening 15 is slightly wider than the width of the capsule 6 . The ramp 17 facilitates the dropping of the capsule 6 , and the capsule 6 in the pit 18 can drop into the drop opening 15 through the ramp 17 .

[0033] The tray 4 is also slidably connected to a support rod 8 arranged in a horizontal direction, one end of the support rod 8 is arranged in a pit 18, a lifting rod 3 is also arranged in the pit 18, the lifting rod 3 is also connected to a driving mechanism, and the tray 4 is also connected to a vibrator 7.

[0034] Each pit 18 is correspondingly provided with two support rods 8, and the two support rods 8 are symmetrically arranged along the center line of the pit 18. The upper surface of the support rod 8 is an inclined surface and is adapted to the capsule 6, so as to better fix the capsule 6 and reduce the shaking of the capsule 6.

[0035] The cross section of the lifting rod 3 is an isosceles triangle, and the lower surface of the lifting rod 3 is parallel to the upper surface of the tray 4. In the initial state, the upper surface of the lifting rod 3 is lower than the upper surface of the support rod 8 to prevent the lifting rod 3 from affecting the placement of the capsule 6. In this example, one tray 4 corresponds to two lifting rods 3, and both ends of the lifting rod 3 pass through the tray 4, so that the capsule 6 can move on the tray 4. Under the action of the vibrator 7, the capsule 6 can fall into the pit 18.

[0036] The driving mechanism includes an electric push rod 1 arranged in a vertical direction, the lower end of which is connected to a lifting rod 3 through a connecting rod 2. The electric push rod 1 and the connecting rod 2 are symmetrically arranged on both sides of the tray 4 to prevent the connecting rod 2 from affecting the movement of the capsule 6.

[0037] The tray 4 is also provided with a main air pipe 13 and a bronchial pipe 10, which are arranged on both sides of the main air pipe 13 and are connected to each other; a secondary piston 9 is slidably connected inside the bronchial pipe 10, and one end of the secondary piston 9 close to the pit 18 is fixedly connected to the support rod 8.

[0038] The main air pipe 13 is slidably connected to a main piston 14 , and the upper end of the main piston 14 is fixedly connected to a pressure rod 11 , which is arranged just below the lifting rod 3 .

[0039] One pit 18 corresponds to one main airway 13 and two bronchi 10. The two bronchi 10 are symmetrically arranged on both sides of the main airway 13. When the main piston 14 moves upward, it can drive the two secondary pistons 9 to move toward the pit 18, so that the support rod 8 moves into the pit 18, thereby providing sufficient support for the capsule 6.

[0040] A pressing block 12 is fixedly connected to the pressing rod 11 . A spring 16 is sleeved on the pressing rod 11 . The upper end of the spring 16 is connected to the lower end of the pressing block 12 , and the lower end of the spring 16 is connected to the tray 4 .

[0041] In the initial state, when the spring 16 is in a compressed state, the support rod 8 is slidably disposed in the recess 18 , thereby providing support for the capsule 6 , and the upper surface of the support rod 8 is adapted to the capsule 6 .

[0042] The spring 16 plays a resetting role for the movement of the pressure rod 11. The spring 16 is arranged on the outside of the main airway 13. One end of the support rod 8 is inserted into the bronchus 10 and is slidably connected to the bronchus 10. The other end of the support rod 8 passes through the bronchus 10 and is slidably set in the pit 18.

[0043] In the initial state, the upper surface of the lifting rod 3 is lower than the upper surface of the support rod 8, and the lifting rod 3 presses the pressing rod 11 downward, thereby compressing the spring 16, and then driving the support rod 8 to move into the pit 18 through the secondary piston 9, thereby providing sufficient support for the capsule 6.

[0044] The tray 4 is also fixedly connected with a plurality of baffles 5, which are connected to each other to form a space for placing the capsule 6. Both ends of the baffle 5 are provided with a slide groove, and both ends of the lifting rod 3 are slidably arranged in the slide groove, and the connecting rod 2 can be vertically arranged in the slide groove, and the width of the connecting rod 2 is adapted to the slide groove, so as to prevent the capsule 6 from sliding out through the slide groove.

[0045] The present invention also proposes a method for using a capsule filling sorting device, which uses the capsule filling sorting device described in this embodiment, including the following steps:

[0046] S1: In the initial state, the lifting rod 3 is in contact with the upper end of the pressing rod 11, and the spring 16 is in a compressed state, so that one end of the supporting rod 8 is located in the pit 18, and the upper surface of the lifting rod 3 is lower than the upper surface of the tray 4;

[0047] S2: placing the capsule 6 on the tray 4 and starting the vibrator 7, which drives the tray 4 to vibrate, so that the capsule 6 enters the pit 18, and the capsule 6 is supported by the support rod 8;

[0048] S3: The electric push rod 1 is started, and the electric push rod 1 drives the lifting rod 3 to move upward through the connecting rod 2. The lifting rod 3 drives the capsule 6 to rotate, so that the heavy end of the capsule 6 moves downward. Under the action of the spring 16, the pressure rod 11 rises, driving the main piston 14 to move upward, so that the secondary piston 9 in the bronchus 10 moves away from the pit 18;

[0049] S4: With the movement of the secondary piston 9, the support rod 8 no longer supports the capsule 6, and the capsule 6 slides to the drop opening 15 via the inclined platform 17, and falls from the drop opening 15 to the corresponding collection device.

[0050] In addition, when the vibrator 7 vibrates, it can drive the capsule 6 to fall into the pit 18. At this time, the support rod 8 is also located in the pit 18, thereby supporting the capsule 6. When the lifting rod 3 rises, it will drive the capsule 6 to tilt. Since the big end of the capsule 6 is heavier, it will drive the capsule 6 to fall with the big end facing down. The capsule 6 falls into the collecting device through the drop port 15, thereby completing the sorting of several capsules 6 with high sorting efficiency. By setting a sufficient number of pits 18, it can be suitable for the sorting of large quantities of capsules 6, and the sorting efficiency is high and the error rate is low, which is beneficial to the subsequent capsule processing.

[0051] In addition, in the initial state, the lifting rod 3 presses the pressure rod 11 downward, driving the main piston 14 to descend, thereby driving the support rod 8 to extend into the pit 18 through the secondary piston 9, thereby supporting the capsule 6. When the lifting rod 3 no longer presses the pressure rod 11, under the action of the spring 16, the pressure rod 11 moves upward, driving the main piston 14 to rise, and the secondary piston 9 drives the support rod 8 to move, so that the support rod 8 no longer supports the capsule 6. The capsule 6 slides to the drop port 15 via the inclined platform 17, and falls from the drop port 15 to the corresponding collection device, thereby realizing the automatic dropping of the capsule 6 after sorting.

[0052] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
