Description

Technical Field

[0001] This utility model relates to the technical field of bottling production line equipment in the pharmaceutical industry, specifically an automatic bagging machine for solid dosage forms. Background Technology

[0002] The pharmaceutical industry currently faces a technological bottleneck in the production of special packaging for solid dosage forms: domestic pharmaceutical companies generally lack automated solutions for the unique process of inner-wall bagging. Limited by existing technology, production lines still rely on traditional manual bagging methods, which have multiple limitations: First, they cannot be integrated with modern pharmaceutical equipment for continuous online production, severely restricting production efficiency; second, manual operation is slow, resulting in low output per workstation; third, to ensure production capacity, a large number of operators must be deployed, increasing labor costs and making it difficult to guarantee process consistency. Most notably, this outdated manual operation method is completely incompatible with the production requirements of modern pharmaceutical production lines, becoming a key bottleneck restricting capacity expansion and process standardization. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an automatic bagging machine for solid dosage forms.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An automatic bagging machine for solid dosage forms includes a frame, on which a bag suction device, a bag placement device, a bag support device, and a turntable are mounted. The bag suction device includes two vacuum suction heads, and the bag placement device is located between the two vacuum suction heads. The bag placement device can move up and down relative to the frame. The bag placement device includes a plurality of support rods evenly distributed in a ring. The lower part of the support rods is configured with a D-shaped structure, and the upper part of the plurality of support rods is connected to the bag support device. The bag support device can drive the plurality of support rods to move closer or further apart synchronously. The turntable is located below the two vacuum suction heads and has a plurality of bottle feeding stations.

[0005] In the above structure, the two vacuum suction heads of the bag suction device can suck up the bag and open the top opening of the bag. The turntable transports the bottle to the bottom of the bag. The multiple support rods of the bag placement device enter the bag through the bag opening and then push the bag into the bottle through the top opening. The bag supporting device drives the multiple support rods to move away from each other synchronously, thereby opening the bag. In addition, the D-shaped structure at the bottom of the support rods can make the bag fit closer to the inner wall of the bottle.

[0006] The bag-laying device includes a support plate, on which a bag-supporting device is mounted. The bag-supporting device includes a fixed plate, which is fixedly mounted on the lower part of the support plate by multiple L-shaped plates. A first drive motor is fixedly mounted on the upper part of the support plate, and the output end of the first drive motor is connected to a drive plate. The drive plate is located on the lower part of the support plate and the upper part of the fixed plate. The drive plate has multiple spiral guide grooves, and the distance between the spiral guide grooves and the center point of the drive plate gradually increases. The fixed plate has multiple strip-shaped sliding holes evenly distributed along the diameter direction of the fixed plate. A support rod corresponds to each strip-shaped sliding hole. A slider is fixedly connected to the support rod and slides through the slider and the strip-shaped sliding hole. The top of the support rod passes through the spiral guide groove and can slide within the spiral guide groove.

[0007] In the above structure, when the first drive motor starts, it drives the drive disk to rotate. The spiral guide groove on the drive disk causes the support rod to slide relative to the diameter of the fixed disk, thereby causing multiple support rods to move closer to each other or further apart synchronously.

[0008] A vertical slide mechanism is provided on one side of the frame. The vertical slide mechanism is connected to the support plate and can drive the support plate to move up and down.

[0009] The two vacuum suction heads of the suction bag device are a first vacuum suction head and a second vacuum suction head. The first vacuum suction head is mounted on a rotating plate. The two ends of the rotating plate are rotatably mounted on the frame via rotating shafts. The rotating plate is horizontally set. The rotating shaft at one end of the rotating plate is connected to a rotating cylinder. The rotating cylinder drives the rotating shaft and the rotating plate to rotate. The second vacuum suction head is fixedly set.

[0010] Initially, the first vacuum suction head faces downwards to pick up the bag, then rotates 90 degrees to adjust the bag from a horizontal to a vertical position. At this time, the first and second vacuum suction heads are positioned opposite each other, and the second vacuum suction head is activated to open the bag opening.

[0011] A bag storage slot is fixedly installed on one side of the frame. The bag storage slot is located near the first vacuum suction head, and bag materials are placed horizontally in the bag storage slot.

[0012] The turntable is rotatably mounted relative to the frame, and the second drive motor drives the turntable to rotate.

[0013] An arc-shaped baffle is provided on the outer side of the turntable, and the arc-shaped baffle is vertically arranged along the outer circumference of the turntable.

[0014] The bottle feeding station is enclosed by vertical panels, with an opening on one side, which is located away from the center point of the turntable.

[0015] The turntable works with the bottle conveyor belt on the production line to transport bottles to the bagging station. Specifically, the unobstructed area of ​​the arc-shaped baffle is the inlet and outlet. Bottles enter the bottle feeding station through the opening at the inlet end. The turntable rotates and moves the bottles to the bottom of the bagging device for bagging. At this time, the bottles are blocked by the arc-shaped baffle and kept inside the bottle feeding station. When the turntable rotates to the outlet end, the bottles can be sent out with the bottle conveyor belt on the production line.

[0016] The beneficial effects achieved by this utility model are: This invention is applicable to the special process of inner wall bagging of bottles. It has a high level of automation and intelligence, and is fast, which not only saves labor, but also ensures high bagging quality.

[0017] The bag-supporting device of this invention allows the bag to fit closer to the inner wall of the bottle, resulting in high-quality bagging. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: like Figures 1-5 As shown, an automatic bagging machine for solid dosage forms includes a frame 18. The frame 18 is equipped with a bag suction device, a bag placement device, a bag support device, and a turntable 11. The bag suction device includes two vacuum suction heads. The bag placement device is located in the middle of the two vacuum suction heads and can move up and down relative to the frame 18. The bag placement device includes a plurality of support rods 5 evenly distributed in a ring. The lower part of the support rods 5 is configured with a D-shaped structure. The upper part of the plurality of support rods 5 is connected to the bag support device. The bag support device can drive the plurality of support rods 5 to move closer or further apart synchronously. The turntable 11 is located below the two vacuum suction heads and has a plurality of bottle feeding stations 13.

[0022] The bag-laying device includes a support plate 1, which is horizontally positioned. A bag-supporting device is mounted on the support plate 1, comprising a fixed plate 4. The fixed plate 4 is fixedly mounted on the lower part of the support plate 1 by four L-shaped plates. A first drive motor 2 is fixedly mounted on the upper part of the support plate 1, and the output end of the first drive motor 2 is connected to a drive plate 3. The drive plate 3 is positioned in the space between the lower part of the support plate 1 and the upper part of the fixed plate 4. The drive plate 3 has four spiral guide grooves 15, the distance between the spiral guide grooves 15 and the center point of the drive plate 3 gradually increases, i.e., the curvature of the spiral guide grooves 15 gradually changes. Four strip-shaped sliding holes 16 are evenly distributed on the fixed plate 4, arranged along the diameter direction of the fixed plate 4. A support rod 5 corresponds one-to-one with each strip-shaped sliding hole 16. A slider 17 is fixedly connected to the support rod 5 and slidably connected to the strip-shaped sliding hole 16. The slider 17 is horizontally slidably connected to the strip-shaped sliding hole 16, and the vertical position of the slider 17 is supported by the strip-shaped sliding hole 16. The top of the support rod 5 passes through the spiral guide groove 15 and can slide within the spiral guide groove 15.

[0023] In the above structure, when the first drive motor 2 starts, it drives the drive disk 3 to rotate. The spiral guide groove 15 on the drive disk 3 causes the support rod 5 to slide relative to the diameter direction of the fixed disk 4, so that the multiple support rods 5 move closer to each other or further away from each other in sync.

[0024] A vertical slide mechanism is provided on one side of the frame 18. The vertical slide mechanism is connected to the support plate 1 and can drive the support plate 1 to move up and down. The vertical slide mechanism can be a linear slide structure from the prior art and can be driven by a motor.

[0025] The two vacuum suction heads of the suction bag device are a first vacuum suction head 9 and a second vacuum suction head 10. The first vacuum suction head 9 is mounted on a rotating plate 7. The two ends of the rotating plate 7 are rotatably mounted on the frame 18 via rotating shafts. The rotating plate 7 is horizontally set. The rotating shaft at one end of the rotating plate 7 is connected to a rotating cylinder 6. The rotating cylinder 6 drives the rotating shaft and the rotating plate 7 to rotate. The second vacuum suction head 10 is fixedly set.

[0026] A bag storage slot 8 is fixedly installed on one side of the frame 18. The bag storage slot 8 is located near the first vacuum suction head 9, and bag materials are placed horizontally in the bag storage slot 8.

[0027] Initially, the first vacuum suction head 9 faces downwards, which can pick up a bag in the bag storage slot 8. Then, it is rotated 90 degrees to adjust the bag from a horizontal state to a vertical state. At this time, the first vacuum suction head 9 and the second vacuum suction head 10 are set opposite each other. The second vacuum suction head 10 is activated, thereby opening the upper opening of the bag.

[0028] The turntable 11 is rotatably mounted relative to the frame 18, and the second drive motor 14 can drive the turntable 11 to rotate via belt drive.

[0029] An arc-shaped baffle 12 is provided on the outer side of the turntable 11, and the arc-shaped baffle 12 is vertically arranged along the outer circular surface of the turntable 11. The bottle feeding station 13 is surrounded by a vertical plate, and has an opening on one side. The opening is located away from the center point of the turntable 11. The turntable 11 is provided with a material inlet at the bottle feeding station 13 to accommodate bottles.

[0030] The turntable 11 works in conjunction with the bottle conveyor belt on the production line to transport bottles to the bagging station. Specifically, the unobstructed portion of the arc-shaped baffle 12 is the inlet and outlet. Bottles enter the bottle feeding station 13 through the opening at the inlet. The turntable 11 rotates, carrying the bottles to the area below the bagging device for bagging. At this point, the bottles are blocked by the arc-shaped baffle 12 and held inside the bottle feeding station 13. Once the turntable 11 rotates to the outlet position, the bottles are then conveyed out by the bottle conveyor belt on the production line. This inlet and outlet method is common in pharmaceutical production lines.

[0031] In addition, photoelectric sensors can be installed at the bottle inlet and bagging positions of turntable 11 to detect whether a bottle has entered the station.

[0032] The specific operation process of this utility model is as follows: the photoelectric sensor detects a bottle at the bottle inlet position and triggers the second drive motor 14. The second drive motor 14 drives the turntable 11 to rotate, so that the turntable 11 rotates one station, that is, reaches the bagging station. After the photoelectric sensor detects the bottle at the bagging station, the bag suction program is started. The first vacuum suction head 9 faces downward and sucks up a bag in the bag storage slot 8. Then it rotates 90 degrees to adjust the bag from a horizontal state to a vertical state. At this time, the first vacuum suction head 9 and the second vacuum suction head 10 are set opposite each other. The second vacuum suction head 10 is started, thereby opening the upper opening of the bag. After the bag blowing process is completed, the bag placement program is triggered. The vertical slide mechanism drives the support plate 1 to move downwards. Multiple support rods 5 of the bag placement device enter the bag through the bag opening, and then push the bag into the bottle through the upper opening. The bag is placed into the polyethylene bottle by the bag placement device, and the bottom of the bottle and the bottom of the bag are joined. Then the bag opening program is started. The bag opening device drives the four support rods 5 to move away from each other synchronously, thereby moving horizontally into the surrounding space of the polyethylene bottle, so that the outside of the bag is close to the inner wall of the bottle, completing the bag placement. Afterwards, the bag opening device resets and the bag placement device returns to its original position. The turntable 11 continues to rotate two more stations to send out the bagged bottle.
