Description

Technical Field

[0001] The utility model relates to the technical field of tube filling equipment, in particular to a tube overturning and feeding mechanism. Background Art

[0002] In the filling industry, tube filling is a common method, such as cryopreservation tubes, sampling tubes, test tubes, etc. In the small-batch automated production of such tube packaging materials, automated loading can be achieved in the loading stage, but it can only be performed for tube packaging materials with obvious differences in tube body structure, such as tube mouths with flanges, etc., which can clearly distinguish between the tube mouth and the tube tail. As for tube packaging materials with a tube body that is almost a smooth cylinder, automated loading cannot distinguish the direction of the tube mouth, and can only be manually sorted, organized, and stacked before loading, which is not only time-consuming and labor-intensive, but also increases the pollution that may be caused by manual intervention. Therefore, a tube body flipping loading mechanism is needed that can distinguish the direction of the tube mouth and automatically load tube packaging materials with smooth cylindrical shapes.

[0003] A Chinese patent document with a publication date of December 3, 2019 and publication number CN110525939A discloses a flipping mechanism, a device and a flipping equipment. The flipping mechanism includes a power part, a transmission part and a rotating part. The power part is connected to the rotating part by means of the transmission part. The power part provides linear motion, and the transmission part converts the linear motion into an axial rotation of the rotating part.

[0004] The disadvantage of the above-mentioned flipping mechanism, device and flipping equipment is that by providing a transmission part that can convert linear motion into rotation, the linear power part can be suitable for the flipping equipment, but because the clamping mechanism of the flipping mechanism, device and flipping equipment cannot fix the smooth cylinder, it is not suitable for smooth cylindrical tube packaging materials, and cannot distinguish the direction of the tube mouth.

[0034] Embodiment 2:

[0035] exist Figure 4 In the shown embodiment 1, the utility model provides a technical solution: a flip loading mechanism for a tube body 19, comprising a flip mounting seat 11, the flip mounting seat 11 is connected to the support column 3 through a horizontal plate 5; first bearings 2 are arranged at both ends of the support column 3, and a rotating shaft 4 is arranged inside the support column 3; the shaft end of the rotating shaft 4 is connected to the first bevel gear 6. Conventional tubes on the market usually have a threaded termination flange at a section of the tube cover, which can distinguish the direction of the tube mouth through other forms such as a shaking bucket, while the tube packaging materials with a smooth and consistent tube body cannot distinguish the direction of the tube mouth through the outside. This embodiment is not only suitable for the production of conventional tube body 19 packaging materials, but also can be used for the production of tube packaging materials with smooth and consistent tube bodies. This embodiment is roughly the same as embodiment 1, except that in this embodiment, small-sized cryogenic tubes are loaded, and the tube bodies of the small-sized cryogenic tubes are also smooth and consistent, but the length of the small-sized cryogenic tubes is smaller than that of the large-sized cryogenic tubes.

[0036] Since the installation positions of the first detection element 15 and the second detection element 16 are adjustable, the first detection element 15 can move in the hole on the surface of the flip mounting seat 11, the second detection element 16 can be telescopically changed in position through the hole on the end cover 14 of the flip mounting seat 11, and the specifications of the flip limiter outer lining 17 and the flip cavity inner lining 18 are replaceable, in this embodiment, compared with Example 1, the installation positions of the first detection element 15 and the second detection element 16 are changed, and the specifications of the flip limiter outer lining 17 and the flip cavity inner lining 18 are also changed. Figure 3 This is a schematic diagram of a feeding mechanism for turning over a tube 19 of the utility model. Figure 4This is a schematic diagram of the second embodiment of the turning feeding mechanism of the tube body 19 of the utility model, referring to Figure 3 and Figure 4 contrast, Figure 3 The middle tube body 19 is a large cryopreservation tube. Figure 4 The middle tube body 19 is a small cryopreservation tube. Figure 3 The first detection element 15 is located outside, that is, at the end of the surface of the flip mount 11 that is farthest from the feed port 11-2, and the second detection element 16 is extended to the longest position, that is, the end farthest from the feed port 11-2; Figure 4 The first detection element 15 is located inside, that is, at the end of the flip mount 11 that can be installed on the surface closest to the feed port 11-2, and the second detection element 16 is shortened to the shortest position, that is, the end closest to the feed port 11-2, and Figure 4 The specifications of the outer lining 17 of the flip stopper and the inner lining 18 of the flip cavity are smaller. Figure 3 The specifications of the outer lining 17 of the turnover limiter and the inner lining 18 of the turnover cavity are larger.

[0039] The utility model discloses a flip feeding mechanism for a tube body 19, and its working principle is as follows: the tube body 19 enters the feed port 11-2 through an external conveying channel, and then enters the notch of the flip limiter 10 through the feed port 11-2. At this time, the first detection element 15 detects a signal, indicating that the tube body 19 is in place, and the second detection element 16 detects a signal, indicating that the tube tail is detected, and the driving mechanism 1 works to drive the first bevel gear 6 at the end of the rotating shaft 4 to rotate, and the second bevel gear 7 meshing therewith drives the flip limiter 10 to rotate counterclockwise by a certain angle, so that the tube body 19 is vertical, and enters the guide sleeve 12 through the discharge port 11-3 to realize discharge. If the second detection element 16 does not detect a signal, indicating that the tube tail is not detected, the flip limiter 10 rotates clockwise by a certain angle, so that the tube body 19 is vertical, and enters the guide sleeve 12 through the discharge port 11-3 to realize discharge. The mechanism can also change the size of the flip cavity 11 - 1 and the flip stopper 10 by replacing the flip cavity lining 18 and the flip stopper outer lining 17 to adapt to the production of tubes 19 of different lengths.

[0040] Although the terms such as flip limiter, flip mount, first detection element and second detection element are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
