Description

Technical Field

[0001] This utility model relates to a pharmaceutical packaging machine, specifically to a blister pack conveying system and a blister packing machine. Background Technology

[0002] Pharmaceutical packaging manufacturing processes must comply with relevant environmental production control requirements. In existing processes, blister packaging machines are typically located in clean areas, while blister cartoning machines are located in non-clean areas. A partition wall separates the clean and non-clean areas, creating an isolated production environment for solid dosage form blister packaging and cartoning. Due to process limitations, mechanical moving parts located in the non-clean area are not allowed to move into the clean area to prevent mechanical movement from circulating between the clean and non-clean areas, which could contaminate the clean area's production environment with bacteria and microorganisms. Existing blister packaging and cartoning machines linked by the partition wall can be broadly categorized into two methods: one involves a conveyor belt at the partition wall for mechanical transport of blister packs; the other uses a fixed slide with a height difference at the partition wall to slide the blister packs in the clean area using inertial limiting. These two transport devices currently exhibit two different characteristics. When using a conveyor belt to transport blister packs, friction and slippage occur, making it difficult to accurately position and arrange the blister packs, thus creating difficulties for subsequent robotic integration and high-speed cartoning processes. The use of a non-powered inertial limiting sliding transfer method requires the installation of transverse partitions between blister packs to limit their sliding. The installation of these partitions restricts the multi-channel flexible output characteristics of the blister packaging machine, posing a significant challenge to rapid production changeover. Furthermore, since the air pressure in the clean area is significantly higher than that in the non-clean area, the blister packs are easily disturbed by the high-pressure air discharged from the clean area to the non-clean area when sliding inertially through the partitions. This can cause the blister packs to become suspended, deflected, or jammed, affecting the normal production cycle and making it difficult to achieve high-speed synchronous production from blister packaging to carton packaging. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides an isolation zone conveying system with a more reasonable structure and more stable transportation.

[0004] This isolated zone conveying system includes a clean area, a non-clean area, and an isolated conveying unit. The clean area and the non-clean area are separated by a partition wall. The isolated conveying unit extends from the clean area through the partition wall to the non-clean area. A section of the conveying path of the isolated conveying unit in the clean area is located in an isolated sealed chamber. The isolated sealed chamber has a feed opening in the clean area and a discharge port in the non-clean area or at the boundary between the clean and non-clean areas. The isolated conveying unit exits from the discharge port of the isolated sealed chamber.

[0005] The air pressure in the clean area is greater than that in the non-clean area.

[0006] The feed opening of the isolation and sealing chamber is located at the top of the isolation and sealing chamber.

[0007] The isolation conveying unit includes a mounting base, a drive belt, a pulley, and several conveying grids. The drive belt is wound around the pulley and has two belts, left and right. The two ends of the conveying grids are respectively connected to the left and right drive belts. Several conveying grids are equally connected to the drive belts. A support platform is provided between the two drive belts. The conveying grids push materials above the support platform.

[0008] The surface of the support platform is provided with a groove extending along the conveying direction, and the bottom of the conveying grid has a protrusion, which extends downward into the groove of the support platform.

[0009] The surface of the support platform is provided with multiple grooves, the distance between two adjacent grooves is less than the length of the blister pack, and the bottom of the conveying grid has multiple protrusions, each protrusion corresponding to a groove.

[0010] The two ends of the conveyor grid are connected to support wheels, and the mounting base is provided with a lower support surface. The lower support surface is located below the transmission belt, and the support wheels located below act on the lower support surface.

[0011] The mounting base is provided with an upper support surface, which is located on the outside of the transmission belt, and the support wheel located above it acts on the upper support surface.

[0012] According to the isolation zone conveying system provided by this utility model, by setting up an isolation sealed chamber in the clean area and arranging the isolation conveying unit therein, the blister packs are transferred and conveyed in a zoned isolation manner between the clean area and the non-clean area. This conveying method not only solves the problem of cross-connection between the non-clean area and the clean area caused by mechanical motion cycle, but also makes the conveying of blister packs very stable.

[0022] like Figure 1 As shown, the blister packing and cartoning integrated machine includes a blister packaging machine and a blister cartoning machine. The blister packaging machine completes the forming, packaging, and cutting of blister packs, while the blister cartoning machine is used to pack the cut blister packs into cardboard boxes. To meet relevant environmental production control requirements, the blister packaging machine is located in clean area A, and the blister cartoning machine is located in non-clean area B, with a partition wall 4 between clean area A and non-clean area B. It is worth mentioning that clean area A is enclosed by a glass outer wall (of course, other materials can also be used), and non-clean area B is enclosed by a glass outer wall, but it is also possible to omit the glass outer wall. However, clean area A is a closed structure and must not be opened. It has higher requirements for the bacterial content in the air to ensure that no bacteria enter when the blister packs are filled into capsules, in order to meet international hygiene standards for pharmaceutical packaging.

[0023] To transport the blister packs cut by the blister packaging machine to the blister cartoning machine, that is, to transport the blister packs from clean area A to non-clean area B, while preventing non-clean area B from contaminating clean area A, this utility model provides an isolated zoned conveying system, such as... Figure 2 and Figure 3 As shown, this isolated zone transport system includes a clean area A, a non-clean area B, and an isolated transport unit 1. Clean area A and non-clean area B are separated by a partition wall 4. Figure 3 As shown, the isolation conveying unit 1 extends from clean area A through partition wall 4 to non-clean area B. A section of the conveying path of the isolation conveying unit 1 in clean area A is located within the isolation sealing chamber 2 (the isolation sealing chamber 2 is constructed from metal plates, glass plates, or other types of sheet materials). Figure 2 As shown, the isolation and sealing chamber 2 has a feed opening 20 in the clean area A (the cut blister packs enter the isolation and conveying unit 1 through the feed opening 20), and the isolation and sealing chamber 2 has a discharge port 21 in the non-clean area B or at the junction of the clean area A and the non-clean area B, and the isolation and conveying unit 1 comes out from the discharge port 21 of the isolation and sealing chamber 2.

[0024] During operation, the rotary suction and release robot 3 picks up the blister packs cut by the cutting device 5 and, through rotation and transfer, moves the blister packs through the feed opening 20 of the isolation and sealing chamber 2 to the isolation and conveying unit 1. In this way, the blister packs enter the isolation and sealing chamber 2. The isolation and conveying unit 1 conveys the blister packs forward and they come out from the discharge port 21 of the isolation and sealing chamber 2 to continue forward. The characteristic of this type of isolated zone conveying system is that the non-clean area B extends to the clean area A through the isolated sealed chamber 2. In other words, the isolated sealed chamber 2 constitutes part of the non-clean area B. The non-clean area B and the clean area A are only connected through the feed opening 20 of the isolated sealed chamber 2. The area of ​​the feed opening 20 can be made very small to reduce the contamination of the clean area A by the non-clean area B. At the same time, the air pressure in the clean area A can be increased to be greater than that in the non-clean area B. This ensures that the air in the clean area A can only enter through the feed opening 20 of the isolated sealed chamber 2 and exit through the discharge port 21 of the isolated sealed chamber 2. In this way, the air in the non-clean area B cannot enter the clean area A through the feed opening 20 of the isolated sealed chamber 2, thus isolating the clean area A from contamination and ensuring that the blister packaging machine can package in a sterile environment.

[0025] It is worth mentioning that the outlet 21 of the isolation sealing chamber 2 can be located in the non-clean area B. In this case, the isolation sealing chamber 2 needs to pass through the partition wall 4 to reach the non-clean area B on the right (a seal is formed between the outer wall of the isolation sealing chamber 2 and the partition wall 4 to prevent air from the non-clean area B from entering the clean area A through gaps). This allows the outlet 21 to be located in the non-clean area B. The isolation sealing chamber 2 with this structure is longer in length, which can better guide the blister pack forward. The air pressure inside the isolation sealing chamber 2 will gradually decrease forward, making the blister pack exit more smoothly from the outlet 21, thus facilitating the stable delivery of the blister pack. Alternatively, the outlet 21 of the isolation sealing chamber 2 can be located at the junction of the clean area A and the non-clean area B, that is, the outlet 21 of the isolation sealing chamber 2 is located at the partition wall 4 (a seal is formed between the outlet 21 of the isolation sealing chamber 2 and the partition wall 4 to prevent air from the non-clean area B from entering the clean area A through gaps). Both methods can be implemented.

[0026] In addition, such as Figure 2 As shown, the feed opening 20 of the isolation sealing chamber 2 is located at the top of the isolation sealing chamber 2. This facilitates the rotary suction and release robot 3 to suck up the blister packs cut by the cutting device 5 and place them onto the isolation conveying unit 1.

[0027] like Figure 4 and Figure 5As shown, this type of bar screen conveying unit includes a mounting base 10, a drive belt 12, a pulley 14, and several conveying bars 13. The drive belt 12 is wound around the pulley 14, and the pulley 14 is driven to rotate by a power source. The pulley 14 moves the drive belt 12 in a cyclical motion. Of course, the bar screen conveying unit can also use existing bar screen conveying devices on the market. Existing bar screen conveying devices also include bar screen conveyor belts, which are evenly distributed with several pusher plates.

[0028] like Figure 5 As shown, the transmission belt 12 has two sections, left and right. The two ends of the conveyor strips 13 are connected to the left and right transmission belts 12 respectively (the left end of the conveyor strip 13 is connected to the left transmission belt 12, and the right end of the conveyor strip 13 is connected to the right transmission belt 12). Several conveyor strips 3 are evenly connected to the transmission belts 12, forming a spacing between adjacent conveyor strips 13 for placing blister packs. A support platform 15 is provided between the two transmission belts 12, and the conveyor strips 13 push material above the support platform 15. During operation, the power source drives the pulley 14 to rotate, which in turn drives the transmission belts 12 forward in a cyclical motion. Since the two ends of the conveyor strips 13 are connected to the left and right transmission belts 12, they also move forward together in a cyclical motion. The robotic arm picks up the blister packs and places them on the support platform 15, positioned between adjacent conveyor strips 13. As the conveyor strips 13 move forward, they push the blister packs P forward. This structure eliminates the partitions between multiple channels and replaces the existing multi-channel, multi-push plate structure with a single conveyor grid 13, greatly reducing manufacturing difficulty and cost. At the same time, it eliminates the need for any alignment adjustments, significantly reducing the difficulty of equipment installation and commissioning.

[0029] Since the conveyor grid 13 pushes the material above the support platform 15, there will inevitably be a gap between the conveyor grid 13 and the support platform 15. If the blister pack P is twisted or deformed or too thin, the surface of the blister pack P may get stuck in the gap between the conveyor grid 13 and the support platform 15, preventing the subsequent blister packs from being picked up by the robot. To solve this problem, such as... Figure 5 As shown, a groove 150 extending along the conveying direction is provided on the surface of the support platform 15, such as... Figure 6 As shown, the bottom of the conveyor grid 13 has a protrusion 131, such as... Figure 7 and Figure 8As shown, the protrusion 131 of the conveyor bar 13 extends downward into the groove 150 of the support platform 15. In this way, the lower end of the protrusion 131 of the conveyor bar 13 is lower than the surface of the support platform 15. The surface of the blister pack will be stuck outside by the protrusion 131 of the conveyor bar 13 and cannot enter between the conveyor bar 13 and the support platform 15, thereby ensuring that the blister pack can be picked up by the robot in the subsequent process.

[0030] If multiple rows of bubble wrap are conveyed at one time (e.g.) Figure 5 (If three rows are conveyed at once), then multiple grooves 150 are provided on the surface of the support platform 5. The distance between two adjacent grooves 150 is less than the length of the blister pack (multiple rows of blister packs are generally arranged in the length direction; if they are arranged in the width direction, then the distance should be less than the width of the blister pack). The bottom of the conveying grid 13 has multiple protrusions 131, and each protrusion 131 corresponds to a groove 150. In this way, it is impossible for any blister pack to get stuck between the conveying grid 13 and the support platform 15.

[0031] Because the drive belt 12 is relatively long, in order to prevent the drive belt 12 from sagging, such as Figure 7 and Figure 9 As shown, support wheels 130 are connected to both ends of the conveyor grid 13, and a lower support surface 111 is provided on the mounting base 10. The lower support surface 111 is located below the transmission belt 12. The support wheels 130 located below act on the lower support surface 111, that is, the support wheels 130 on the lower section of the transmission belt 12 act on the lower support surface 111. The lower support surface 111 provides support for the support wheels 130, and the support wheels 130 are connected to the transmission belt 12 through the conveyor grid 13. This can prevent the lower section of the transmission belt 12 from sagging downwards and ensure the stability and running accuracy of the transmission belt 12.

[0032] Similarly, an upper support surface 110 is provided on the mounting base 10. The upper support surface 110 is located on the outside of the transmission belt 12. The upper support wheel 130 acts on the upper support surface 110. That is, the support wheel 130 on the upper section of the transmission belt 12 acts on the upper support surface 110. The upper support surface 110 provides support for the support wheel 130. The support wheel 130 is connected to the transmission belt 12 through the conveyor grid 13. This can prevent the upper section of the transmission belt 12 from sagging downward and ensure the stability and running accuracy of the transmission belt 12.
