Description

Technical Field

[0001] The utility model relates to the technical field of food and medicine packaging machinery and equipment, in particular to a pre-filling and plugging system. Background Art

[0002] In the past, the stoppering of vials on prefilled equipment used a stoppering rod in conjunction with a stoppering plate, while the stoppering of prefilled needles or cartridges used sleeve stoppering, which used a sleeve and stoppering rod in conjunction. When the two specifications were replaced, the stoppering mechanism of the stoppering rod did not need to be used for prefilled needles or cartridges, and the drive of the sleeve did not need to be used for vials. As a result, the functional components of the equipment were idle, resulting in a certain amount of waste and increasing the number of parts in the modular design. In addition, the stoppers of vials were easy to fall off during the stoppering process, resulting in unsatisfactory stoppering effects. In addition, the stoppers could not be sucked up and required manual processing, resulting in a slow stoppering speed. Utility Model Content

DETAILED DESCRIPTION

[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] The utility model is a pre-filled plugging system, such as Figure 1-3 As shown, it includes a plug supply device, a plug transfer device 13, a plugging device 12, a plug guide device 11 and a conveying platform 6 for conveying a plate-like component, on which a plurality of containers to be plugged are nested, the plug transfer device 13 includes a first driving mechanism 10 and a plug turning plate 3 detachably connected to the first driving mechanism 10, the plugging device 12 includes a second driving mechanism 8 and a plug pressing rod 2 detachably connected to the second driving mechanism 8, the plug guide device 11 includes a third driving mechanism 7 and a plug guide sleeve 1 detachably connected to the third driving mechanism 7, the plug turning plate 3, the plug pressing rod 2 and the plug guide sleeve 1 are adapted to the containers to be plugged.

[0030] Further, such as Figure 4 As shown, the prefilled plugging system also includes a plugging mechanism 14, which includes a fourth driving mechanism 9 and a plugging rod 4 detachably connected to the fourth driving mechanism 9. The plugging rod 4 is located below the plugging plate 3 and moves up and down to push the plug body onto the plugging plate 3.

[0031] The plug body transfer device 13 includes a first driving mechanism 10 and a plug turning plate 3 detachably connected to the first driving mechanism 10 . The plug turning plate 3 is used to transfer the plug body to the bottom of the plug rod 4 by turning over.

[0032] The plugging device 12 includes a second driving mechanism 8 and a plug pressing rod 2 detachably connected to the second driving mechanism 8. The plug pressing rod 2 is located above the plug guide sleeve 1. The plug pressing rod 2 moves up and down to press the plug body on the plug turning plate 3 into the plug guide sleeve 1 and continue to press it into the bottle mouth.

[0033] The plug guide device 11 includes a third driving mechanism 7 and a plug guide sleeve 1 detachably connected to the third driving mechanism 7. The plug guide sleeve 1 is located above the conveying platform 6 and cooperates with the plug pressing rod 2 through up and down lifting movements to guide the plug pressing rod 2 so that the plug pressing rod 2 presses the plug body into the bottle mouth on the conveying bottle head 6.

[0034] In this embodiment, the first driving mechanism 10, the second driving mechanism 8, the third driving mechanism 7 and the fourth driving mechanism 9 are all servo motors.

[0035] To achieve the above function, the bottom diameter B of the plug rod 2 is not larger than the diameter A of the plug body, and larger than the radius A / 2 of the plug body; the diameter of the guide sleeve 1 is larger than the bottom diameter B of the plug rod 2, such as Figure 4 shown.

[0036] Furthermore, in order to improve efficiency, after the plug pressing rod 2 presses the plug body from the plug turning plate 3 into the plug guide sleeve 1 and completely detaches from the plug turning plate 3, the plug turning plate 3 needs to be returned to its original position to transport a batch of plug bodies again, so the plug pressing rod 2 includes a bottom portion in contact with the plug body and a middle portion for passing through the turning track of the plug turning plate 3, and the plug turning plate 3 is provided with a notch for the middle portion of the plug pressing rod 2 to pass through. The width D of the notch of the plug turning plate 3 is greater than the diameter C of the middle portion of the plug pressing rod 2.

[0037] The plugging plate 3, the plugging rod 2 and the plugging guide sleeve 1 are adapted to the container to be plugged, which may be a vial, a prefilled needle or a cartridge bottle, and are replaced according to different containers to be plugged. Since the plugs of the prefilled needle and the cartridge bottle are relatively small, when the container to be plugged is a prefilled needle or a cartridge bottle, the diameter B of the bottom of the plugging rod 2 is larger than the middle diameter C, such as Figure 4 shown.

[0038] Furthermore, the pre-filling stoppering system further comprises a lifting and rotating filling needle 5 disposed above the conveying platform 6, so that before stoppering, the bottle on the conveying platform 6 is filled by the filling needle 5, such as Figure 2 shown.

[0039] In order to facilitate the understanding of the prefilled stoppering system of this embodiment, the operation method of the prefilled stoppering system is described here, but it is not included in the protection scope. The operation method includes: firstly selecting a suitable stopper rod 2 for installation according to the type of the container to be stoppered; starting the stoppering, such as Figure 5As shown in Figure (a), the plug-turning plate 3 takes the plug, and the plug-pushing rod 4 pushes the plug body onto the plug-turning plate 3, and then the plug-turning plate 3 transports the plug body to the top of the plug guide sleeve 1 and the bottom of the plug pressing rod 2, and the conveying platform 6 transports the bottle to the bottom of the plug guide sleeve 1; Figure 5 As shown in Figure (b), the plug pressing rod 2 moves downward to press the plug body on the plug turning plate 3 into the plug guide sleeve 1; Figure 5 As shown in Figure (c), after the plug body is separated from the plug turning plate 3, the plug turning plate 3 moves back, the descending speed of the plug pressing rod 2 slows down, and the notch of the plug turning plate 3 passes through the middle of the plug pressing rod 2, returning to the plug removing position to remove the plug again. Figure 5 As shown in Figure (d); when there is no interference between the plug turning plate 3 and the plug pressing rod 2, the plug pressing rod 2 and the plug guide sleeve 1 are accelerated and descended synchronously until the distance between the plug guide sleeve 1 and the container to be plugged reaches the set threshold, and the plug guide sleeve 1 stops descending; the plug pressing rod 2 continues to descend, squeezing the plug body in the plug guide sleeve 1 until the plug body is pressed into the bottle mouth, and the plug pressing rod 2 stops descending; the plug pressing rod 2 presses against the plug body and does not move, and the plug guide sleeve 1 moves upward until the plug body is completely separated from the plug guide sleeve 1; the plug pressing rod 2 and the plug guide sleeve 1 rise to their initial positions respectively. Continue plugging. If the type of container to be plugged needs to be changed, replace the appropriate plug pressing rod 2. If reverse plugging occurs, it will be discarded according to the same logic as the plugging of the prefilled needle.

[0040] In summary, the above-mentioned prefilled stoppering system has the following beneficial effects:

[0041] (1) The utility model adopts a sleeve plugging method for all types of containers to be plugged, thereby avoiding idleness of functional components of the equipment, making full use of each functional component, and only replacing the plugging rod as needed, so that the overall structure is more compact, the overall volume is smaller, the equipment cost is lower, the application is more flexible, and the adaptability is wider;

[0042] (2) The utility model uses the plug guide sleeve to guide the plug body on the plug turning plate into the bottle mouth through the plug pressing rod, so that the plug body is not easy to fall off, the plugging positioning is more accurate, and the situation of failure to adsorb and the plug falling after suction will not occur, so that the plugging effect is better, thereby also improving the plugging speed;

[0043] (3) The plug pressing rod of the utility model can pass through the plug flipping plate. As long as the plug body is separated from the plug flipping plate, the plug flipping plate can move toward the starting position to re-take the plug. At the same time, the plug pressing rod continues to press the plug, eliminating the plug body avoidance action and improving the plug insertion speed.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it; although the implementation mode of the utility model is described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the utility model, and such modifications and variations are all within the scope defined by the attached claims.
