Description

Technical Field

[0001] The utility model relates to the field of mechanical automation, and mainly relates to a rubber plug taking and placing device. Background Art

[0002] The temperature probe is a necessary sensor for freeze dryers. Currently, freeze dryers have always used wired temperature probes, which have wiring and location problems. With the entry of wireless temperature probes into the market, they have received widespread attention in the pharmaceutical industry, and some pharmaceutical companies have begun using wireless temperature probes.

[0003] Since the wireless temperature probe is to be placed in the vial and cannot touch the bottle body, it needs to be attached to a supporting structure. The current method used for the vial is to embed the wireless temperature probe into the rubber stopper and suspend the wireless temperature probe in the air based on the position of the rubber stopper and the vial.

[0004] At present, most pharmaceutical factories that use wireless temperature probes adopt manual placement. On the one hand, this method is inconvenient to operate. Operators need to use gloves to place the rubber plug embedded with wireless temperature probes. On the other hand, it does not meet the needs of unmanned production and requires multiple manual interventions during the production process. In order to realize the automatic placement of wireless temperature probes, it has been realized by a two-degree-of-freedom robotic arm in combination with a suction method. Due to the differences in the signal receiving antennas of wireless temperature probes, the suction method is used to place wireless temperature probes with longer antennas, which is easy to damage the antenna and affect the function. Therefore, a rubber plug placement device that is compatible with the plug removal and placement functions is needed. Specifically, a card slot method is adopted, and the structural characteristics of the rubber plug are used to lock the rubber plug before transferring it. It can effectively be compatible with wireless temperature probes with different antenna lengths to solve the above problems. Utility Model Content

[0030] The present invention will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein, and still achieve the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the present invention.

[0031] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0032] Embodiment 1

[0033] like Figure 1As shown, a plug picking and placing device includes a carrier 14 with a plug, a buffer mesh belt 1 for transporting the carrier 14, a limiting mechanism, a transfer mechanism 2 and a freeze-drying conveyor line; the transfer mechanism 2 includes a plug clamp 5, the plug clamp 5 clamps the plug on the carrier 14, and places it on the freeze-drying conveyor line through the transfer mechanism 2. The freeze-drying conveyor line transports containers 8 that need to enter a freeze dryer for drug freeze drying. The plug clamp 5 transfers the plug on the carrier 14 to the container 8, and then the freeze-drying conveyor line transports the container 8 with the plug to the freeze dryer.

[0034] Among them, the transfer mechanism 2 includes a servo motor, a transfer swing arm 6, a transmission shaft 15 and a lifting motor. The servo motor is arranged on the frame of the production line to fix the position of the servo motor. At the same time, the servo motor provides power for the entire transfer mechanism 2 to support the transfer action of the plug clamp 5; the transfer action is realized by the transfer swing arm 6 arranged on the transfer mechanism 2. One end of the transfer swing arm 6 is connected to the servo motor, and the other end is connected to the plug clamp 5, so as to transfer the plug from the carrier 14 to the container 8, thereby realizing the horizontal transfer of the plug.

[0035] At the same time, the transmission shaft 15 is arranged on the transfer swing arm 6, and the lifting motor controls the rotational movement of the transmission shaft 15 through its own forward and reverse movement, so as to realize the taking and placing of the rubber plug.

[0036] Furthermore, the transmission shaft includes a seal, which is sleeved on the transmission shaft. The seal performs sealing when the transmission shaft moves to prevent bacterial growth and facilitate cleaning and sterilization.

[0037] Furthermore, the freeze-drying conveyor line includes a conveying walkway, a rotating star wheel 9 and a conveying guardrail 7. The conveying walkway transports the container 8 containing the medicine to be freeze-dried and not covered with a stopper to a position where the rotating star wheel 9 can achieve transfer. The rotating star wheel 9 then transfers it to a fixed position, making it convenient for the rotating swing arm to smoothly transfer the stopper on the carrier 14 to the container 8. The rotating star wheel 9 is smoothly connected to the trajectory line of the conveying walkway for conveying the container 8, which reduces the vibration problem of the container 8 on different conveying tools and enhances the stability of the freeze-drying conveyor line.

[0038] At the same time, the conveying guardrail 7 is arranged between the conveying walkway and the rotating star wheel 9, and the conveying trajectory of the conveying guardrail 7 is tangent to the trajectory of the rotating star wheel 9, thereby achieving the stability of the container 8 during the conveying process.

[0039] like Figures 4 to 5 As shown, the rubber plug includes a conventional rubber plug and a rubber plug with a temperature probe, etc., so that the top of the rubber plug has an atypical structure, which cannot be achieved by using a vacuum plug suction method. Therefore, the design of the rubber plug fixture 5 can perfectly solve this problem.

[0040] The problem of replacing the plug of the lyophilized drug can be solved by designing the transport mechanism 2, which is convenient and quick.

[0041] Embodiment 2

[0042] like Figures 2 to 3 As shown, the rubber plug fixture 5 comprises a fixture upper rib 10, a fixture lower rib 11 and a fixture slot 12, and the fixture upper rib 10 has a U-shaped opening, thereby ensuring that when the upper end of the rubber plug has other shapes, it can be well compatible and achieve a universal effect.

[0043] The transfer swing arm 6 is provided with a connecting rod 13, through which power is transmitted to the stopper clamp 5. At the same time, the stopper moves back and forth between the conveying channel formed by the buffer mesh belt 1 and the conveying walkway formed by the freeze-drying conveying line through the transfer swing arm 6 of the transfer mechanism 2 to work alternately, effectively ensuring work efficiency.

[0044] Furthermore, the limiting mechanism includes a limiting rod 3 and a limiting stopper rod 4, which are mainly used to limit the travel progress of the carrier 14 to ensure the stability of the carrier 14 itself during the process of the transfer swing arm 6 extracting the plug.

[0045] Furthermore, a temporary storage box is provided on the cache mesh belt 1, and the carriers 14 with collected plugs are transported to the temporary storage box driven by the cache mesh belt 1 for centralized processing, which effectively prevents the carriers 14 from being thrown around randomly and effectively ensures the cleanliness of the production workshop.

[0046] Furthermore, the cache mesh belt 1 is also provided with a carrier 14 guardrail, which limits the carrier 14 from leaving the conveying space of the cache mesh belt 1, and the limiting mechanism limits the specific position of the carrier 14, so that the carrier 14 will not fall over or leave the cache mesh belt 1 when the transfer swing arm 6 transfers the rubber plug.

[0047] Furthermore, the rotating star wheel 9 has a quick-change structure, which enables the disassembly and assembly of rotating star wheels 9 of different specifications.

[0048] Working principle: Before production, the carrier 14 with the plug needs to be placed on the buffer mesh belt 1. After the equipment is started, the carrier 14 is driven to the limit mechanism through the movement of the conveyor mesh belt to limit the carrier 14; at the same time, after the container 8 enters the corresponding position of the rotating star wheel 9 through the conveying channel, the rotating star wheel 9 stops and positions it. At this time, the transfer swing arm 6 moves to take the plug from the carrier 14 and transfer it to the container 8, and at the same time, the plug is pressed on the container 8. At this time, the limiting mechanism releases the carrier 14, and the transfer swing arm 6 deflects to the top of the buffer mesh belt 1 to prepare for the next transfer of the plug. The reciprocating cycle realizes continuous production. Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. In this way, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalent technologies, the utility model is also intended to include these changes and variations.
