Description

Technical Field

[0001] This utility model relates to a pharmaceutical equipment, and more particularly to a capsule packaging machine. Background Technology

[0002] Capsule medications are typically stored in blister packs. One side of the blister pack is made of plastic, with several capsule slots on the plastic to hold the capsules. The plastic surface is then sealed with tin foil. When a patient needs to retrieve the medication, they simply press the plastic to break the foil and remove the capsule. This method of capsule storage effectively protects the capsules from moisture and pressure damage.

[0003] Currently, capsule packaging is carried out using multiple simple machines. First, a thermoforming machine thermo-presses a plastic sheet to form several capsule slots. Then, it is placed in a special carrier for positioning. Next, the capsules are placed in the capsule slots formed on the plastic sheet positioned on the carrier. Finally, the carrier is positioned in a thermo-pressing and laminating mold, and tin foil is thermo-pressed onto the surface. This method requires multiple workstations to work together, resulting in low capsule packaging efficiency and high labor costs. Utility Model Content

Detailed Implementation

[0017] Example: A capsule packaging machine includes a frame 1, a capsule supply and dispensing device 2, a plastic strip 9 feeding tray 3, a plastic strip traction device, a plastic hot pressing forming mold 4, a tin foil feeding tray 5, a tin foil printing mold 6, a tin foil hot pressing mold 7, a cutting and blanking mold 8, and a control system. The plastic strip 9 feeding tray 3 and the tin foil feeding tray 5 are rotatably mounted on one end of the frame 1. The plastic strip 9 led out from the plastic strip 9 feeding tray 3 is intermittently conveyed horizontally forward by the plastic strip traction device. The plastic hot pressing forming mold 4, the tin foil hot pressing mold 7, and the cutting and blanking mold 8 are arranged at intervals on the frame 1 along the conveying direction of the plastic strip 9. The plastic strip 9 sequentially passes through the plastic hot pressing forming mold 4, the tin foil hot pressing mold 7, and the cutting and blanking mold 8. The mold 4 can hot-press the plastic strip 9 that passes through it to form a plurality of capsule grooves 11 on the upper surface of the plastic strip 9. The capsule supply and dispensing device 2 can dispense capsules one by one into the capsule grooves 11. The tin foil strip 10 led out from the tin foil supply tray 5 passes sequentially through the tin foil printing mold 6 and the tin foil hot pressing mold 7. The tin foil printing mold 6 can print on the upper surface of the tin foil that passes through it. The tin foil hot pressing mold 7 can hot-press the tin foil and the plastic strip 9 containing the capsules to form a whole. The cutting and blanking mold 8 can punch and blank the plastic strip 9 with the tin foil that has passed through it. The control system controls the operation of the capsule supply and dispensing device 2, the plastic strip traction device, the plastic hot pressing forming mold 4, the tin foil printing mold 6, the tin foil hot pressing mold 7 and the cutting and blanking mold 8.

[0018] When the capsules are packaged, they are first stored in the capsule supply and dispensing device 2. After the plastic strip 9 is drawn out, it is first hot-pressed by the plastic thermoforming mold 4 to form several capsule slots 11. After the plastic strip 9 is hot-pressed and formed, it reaches the capsule dispensing position, where the capsule supply and dispensing device 2 dispenses the capsules into the capsule slots 11 on the plastic strip 9. The plastic strip 9 continues to move forward with the capsules. At the same time, after the tin foil strip 10 is drawn out, it first passes through the tin foil printing mold 6, where the tin foil surface is printed with information such as the production date, usage, and dosage. The brushed tin foil strip 10 continues to move forward and eventually covers the plastic strip 9. The two enter the tin foil hot-pressing mold 7 together, where the tin foil and plastic strip 9 are hot-pressed together. The tin foil completely seals the capsule groove 11 on the plastic strip 9. The plastic strip 9 with the tin foil continues to move forward into the cutting and blanking mold 8, where the cutting and blanking mold 8 punches and cuts the plastic strip 9 to form a medicine plate of a specific size. The medicine plate can be directly packaged. The above equipment realizes fully automatic capsule packaging. The whole process does not require manual operation and the capsule packaging efficiency is extremely high.

[0019] The capsule supply and dispensing device 2 includes a capsule storage bin 12, a capsule feeding pipe 13, a roller drive device 33, a capsule metering feeding roller 14, and a capsule baffle 15. The capsule storage bin 12, the capsule feeding pipe 13, and the capsule baffle 15 are respectively fixedly installed on the frame 1. The capsule metering feeding roller 14 is installed on the frame 1 and can rotate intermittently. The roller drive device 33 drives the roller to rotate intermittently. The capsule metering feeding roller 14 is provided with a plurality of capsule receiving slots 16. The lower ends of the plurality of capsule feeding pipes 13 are directly opposite the capsule receiving slots 16 on the upper part of the capsule metering feeding roller 14. The capsules in the capsule feeding pipes 13 can enter the capsule receiving slots 16 on the capsule metering feeding roller 14 one by one through the lower end outlet of the capsule feeding pipes 13. The sidewalls between adjacent capsule receiving slots 16 on the cylinder 14 along its rotation direction can seal the lower outlet of the capsule feeding pipe 13. The upper outlet of the capsule feeding pipe is connected to the lower end of the capsule storage bin 12. Capsules in the capsule storage bin 12 can enter the upper end of the capsule feeding pipe 13. The capsules in the capsule feeding pipe can only be conveyed downward along the capsule feeding pipe 13 in a length direction. The arc-shaped capsule baffle 15 can cover the surface of the capsule metering roller 14 to prevent the capsules in the capsule receiving slots 16 from falling before they reach the bottom. The capsule receiving slots 16 at the lower end of the capsule metering roller 14 can be aligned one by one with the capsule slots on the plastic material belt 9. The bottom row of capsules on the capsule metering roller 14 can fall into the capsule slots 11 of the plastic material belt 9 one by one.

[0020] Ideally, a vibration alignment mechanism should also be installed inside the capsule storage bin 12 to ensure that the capsules are neatly arranged before entering the capsule feeding pipe 13. The capsules move downwards along the capsule feeding pipe 13 and eventually enter the capsule receiving slots 16 on the capsule metering feeding roller 14. As the capsule metering feeding roller 14 rotates, capsules are continuously fed into each row of capsule receiving slots 16 on the surface of the capsule metering feeding roller 14. When the capsule metering feeding roller 14 rotates, the capsules will not fall off due to the capsule baffles 15 on its surface. When the capsule receiving slots 16 containing capsules rotate to the bottom position of the capsule metering feeding roller 14, the capsules will fall downwards without obstruction and enter the capsule slots 11 on the plastic conveyor belt 9. This achieves automatic capsule dispensing with high efficiency and prevents overfilling.

[0021] The tin foil printing mold 6 includes a printing support base 17, a printing bracket, a printing head 18, an ink tank 19, a horizontal slider 20, a horizontal drive device, a lifting seat 21, a lifting drive device 22, and a horizontal slide rail 23. The printing support base 17 and the printing bracket are respectively fixedly installed on the frame 1. The horizontal slide rail 23 and the ink tank 19 are fixedly installed on the printing bracket. The printing support base 17 can horizontally support the lower side of the tin foil to be printed. The ink tank 19 contains printing ink. The horizontal slider 20 can reciprocate horizontally. Mounted on a horizontal slide rail 23, a lifting seat 21 is mounted on a horizontal slider 20, allowing for vertical movement. The printing head 18 is fixedly mounted on the lifting seat 21. A horizontal drive device drives the horizontal slider 20 to reciprocate, causing the printing head 18 to alternately move above the printing support base 17 and above the ink tank 19. The ink tank 19 sprays ink onto the surface of the printing head 18. The lifting drive device 22 drives the lifting seat 21 to move vertically. The lowering of the lifting seat 21 causes the printing head 18 to descend and print images on the upper side of the tin foil. During printing on the tin foil surface, the reciprocating movement of the horizontal slider 20 causes the printing head 18 to alternate between the printing and ink-spraying positions. Each transfer is accompanied by one ink spray, ensuring clear printed text.

[0022] An inkjet sensor is installed on the ink tank 19. The inkjet sensor can detect the printhead 18 directly above the ink tank 19. The inkjet sensor communicates with the control system, which can control the ink tank 19 to spray ink based on the sensing information from the inkjet sensor. The inkjet sensor enables automatic ink spraying from the ink tank 19, ensuring that ink spraying occurs when the printhead 18 is directly aligned with the ink tank 19.

[0023] A blister pack conveyor belt 24 is also provided. The conveying start end of the blister pack conveyor belt 24 is located directly below the cutting and blanking die 8. The cutting and blanking die 8 includes an upper cutting die, a lower cutting die, and a cutting cylinder. The upper cutting die is installed directly above the lower cutting die and can move up and down. The cutting cylinder drives the upper cutting die to move up and down. A cutting punch is provided at the lower end of the upper cutting die, and a cutting die is provided on the lower cutting die. The upper edge of the cutting die forms a cutting edge, and a vertically penetrating material dropping channel is formed inside the cutting die. The blister packs punched out by the cutting and blanking die 8 fall onto the blister pack conveyor belt 24 under the action of gravity, and the blister pack conveyor belt 24 directly delivers them to the boxing and packaging station, avoiding manual handling.

[0024] The frame 1 is also equipped with a strip positioning mechanism 25. The strip positioning mechanism 25 and the cutting and unloading mold 8 are arranged sequentially along the conveying direction of the plastic strip 9. The strip positioning mechanism 25 includes a positioning bracket 26, a pressure block 27, a pressing drive device 34, an upper pressure roller 28, and a lower pressure roller 29. The positioning bracket 26 is fixedly installed on the frame 1. The lower pressure roller 29 is rotatably mounted on the positioning bracket 26 around a horizontal axis. The pressure block 27 is slidably mounted on the positioning bracket 26. The pressing drive device 34 drives the pressure block 27 to slide up and down. The upper pressure roller 28 is mounted on the pressure block 27 and can rotate horizontally. The outer circumferential surfaces of the upper pressure roller 28 and the lower pressure roller 29 have recesses that avoid the capsule grooves 11 on the plastic strip 9. The plastic strip 9, which has been hot-pressed with tin foil by the tin foil hot-pressing mold 7, passes between the upper pressure roller 28 and the lower pressure roller 29 and enters the cutting die 8. The upper pressure roller 28, as the pressure block 27 descends, works with the lower pressure roller 29 to clamp the plastic strip 9, preventing it from moving forward. The control system controls the start and stop of the clamping drive device 34. During the stamping and cutting of the plastic strip 9, the pressure block 27 of the strip positioning mechanism 25 descends, driving the upper pressure roller 28 to descend and clamp the plastic strip 9, preventing the plastic strip 9 from being pulled during stamping and causing deviation in the hot-pressing position of the plastic strip 9 by the tin foil hot-pressing mold 7.

[0025] The plastic strip traction device includes a plastic strip waste collection tray 30, a collection servo motor, plastic strip guide rollers 31, and foil guide rollers 32. The plastic strip 9 waste material, after being cut by the cutting die 8, can be wound onto the plastic strip waste collection tray 30. The collection servo motor drives the plastic strip waste collection tray 30 to rotate intermittently for traction and collection. Several plastic strip guide rollers 31 and foil guide rollers 32 are mounted on the frame 1 and can rotate around a horizontal axis. The plastic strip 9 and foil strip 10, drawn from the plastic strip 9 feeding tray 3 and foil feeding tray 5 respectively, are redirected by the plastic strip guide rollers 31 and foil guide rollers 32, ensuring that the plastic strip 9 and foil strip 10 are in a parallel, facing conveying state before entering the foil hot-pressing die 7. The traction of the plastic strip 9 and foil strip 10 is achieved by the plastic strip waste collection tray 30 winding and collecting the waste material.

[0026] The system also includes a tension sensing device for plastic strip 9, a tension sensing device for tin foil strip 10, a tension adjustment mechanism for plastic strip 9, and a tension adjustment mechanism for tin foil strip 10. The tension sensing devices for plastic strip 9 and tin foil strip 10 can sense the tension values ​​of the plastic strip 9 and tin foil strip 10. These devices communicate with the control system to transmit monitoring data. The tension adjustment mechanisms for plastic strip 9 and tin foil strip 10 each include a tension roller and a tension adjusting arm. The tension adjusting arm is rotatably mounted on the frame 1, and the tension roller is rotatably mounted on the tension adjusting arm. The plastic strip 9 and tin foil strip 10 change direction by bypassing the tension rollers of the tension adjustment mechanisms for plastic strip 9 and tin foil strip 10, respectively. The control system controls the tension adjusting arm to swing and change the position of the tension rollers, thereby changing the tension of the plastic strip 9 and tin foil strip 10. The above mechanism can ensure that the plastic strip 9 and the tin foil strip 10 maintain a stable tension, and prevent deviations in the hot pressing of the capsule slot 11, the capsule placement position, and the hot pressing of the tin foil.

[0027] The plastic hot-press forming mold 4, the tin foil hot-pressing mold 7, and the cutting and blanking mold 8 are all symmetrically provided with plastic strip 9 guide grooves. The two sides of the plastic strip 9 in the width direction are slidably inserted into the symmetrically arranged plastic strip 9 guide grooves. The guide grooves are used to guide the plastic strip 9 to ensure its positional accuracy during hot pressing and stamping cutting.

[0028] Both the plastic hot-press forming mold 4 and the tin foil hot-pressing mold 7 include a hot-pressing upper mold, a hot-pressing lower mold, a hot-pressing force application device, a heating wire, and a temperature sensor. The hot-pressing lower mold is fixedly installed on the frame 1, and the hot-pressing upper mold is mounted on the frame 1 and can move up and down. The hot-pressing force application device can drive the hot-pressing upper mold to move up and down and provide downward holding pressure to the hot-pressing upper mold. A hot-pressing punch is provided on the lower side of the hot-pressing upper mold, and a hot-pressing die is formed on the hot-pressing lower mold. The heating wire and the temperature sensor are fixedly installed inside the hot-pressing upper mold. The heating wire can heat the hot-pressing punch, and the temperature sensor can sense the temperature of the hot-pressing punch. The temperature sensor communicates with the control system to transmit temperature data, and the control system controls the heating wire and the hot-pressing force application device to start and stop working. When hot-pressing the plastic strip 9 and hot-pressing the plastic strip 9 and the tin foil strip 10, temperature control is used to prevent the plastic strip 9 from deforming or being damaged, or the capsule groove 11 from not forming properly.
