Description

Technical Field

[0001] The utility model relates to the technical field of medical rubber plug production, in particular to a rubber plug defective product detection and sorting mechanism. Background Art

[0002] Medical rubber plugs include rubber plugs for various dosage forms such as infusion and oral liquid. They are rubber products used to seal the bottle mouth. In order to ensure the quality of rubber plugs, rubber plug manufacturers need to conduct comprehensive tests on the appearance, shape, size, color difference, etc. in addition to testing the physical and chemical properties such as heat source, microorganisms, particles, metal elements, and tensile strength.

[0003] To solve the above problems, a Chinese utility model patent, with the authorization announcement number CN 104384110 B, proposes a fully automatic rubber plug inspection machine, including a feeding mechanism, a feeding arrangement mechanism, a detection turntable, a visual inspection device and a sorting mechanism, wherein the feeding mechanism includes a feeding mechanism guide rail, and the feeding arrangement mechanism includes a discharge guide rail, a small turntable and a dial wheel. Among them, the discharge guide rail uses an inverted U-shaped frame to limit and guide the discharge of the rubber plug, and the inner edge spacing of its two parallel straight edges is slightly larger than the diameter of the rubber plug.

[0004] The above-mentioned prior art also has the following disadvantages: since the rubber plugs are moved to the visual inspection device for inspection of appearance, size and color defects only after feeding and sorting, during the discharging of feeding and sorting, the discharging guide rail is used to guide the sorting at the outlet, and the inner edge spacing of its two parallel straight sides is slightly larger than the diameter of the rubber plug. If unqualified rubber plugs with larger sizes appear, they will form a blockage here, affecting normal material transportation and subsequent visual inspection. Utility Model Content

[0005] In view of this, it is necessary to provide a defective rubber stopper detection and sorting mechanism to solve the technical problem in the prior art that the rubber stopper sorting and discharging area is prone to blockage due to the large-sized individuals.

[0030] The following specifically describes the preferred embodiments of the present utility model in conjunction with the drawings. The drawings constitute a part of this application and are used together with the embodiments of the present utility model to explain the principle of the present utility model, and are not used to limit the scope of the present utility model.

[0031] As Figures 1-4As shown in the figure, the utility model provides a defective rubber stopper detection and sorting mechanism, which includes a slideway 1, a pressure-sensitive detection rod 2 and a sorting component 3. The slideway 1 includes a slide plate 11 and side plates 12. The slideway 1 is arranged adjacent to the discharge port of the vibrating disk to guide the rubber stoppers discharged in rows. Specifically, a conventional vibrating disk in the prior art is adopted to align and discharge the rubber stoppers in rows. The side plates 12 are arranged on one side of the slide plate 11. One end of the slide plate 11 is inclined downward, and its surface is smooth. The rubber stoppers can slide downward along its surface and are further guided to the subsequent detection unit. Moreover, one side of the slide plate 11 is also inclined downward towards the side plates 12 to make the rubber stoppers lean against the side plates 12 and slide downward along the slide plate 11. In order to neatly arrange the rubber stoppers and avoid blockage caused by width limitation, the inclination towards the side plates 12 enables the rubber stoppers to lean against the side plates 12 during downward sliding, playing a role in sorting. The pressure-sensitive detection rod 2 is suspended at the top of the slide plate 11 with an adjustable distance from the side plates 12. The pressure-sensitive detection rod 2 is used to limit the diameter of the rubber stoppers that can pass through. When the diameter size is unqualified, it will be blocked on the pressure-sensitive detection rod 2 and form a pressure-sensitive feedback. Then, in cooperation with the controller for signal processing, the driving part 32 on the sorting component 3 is controlled to rotate the turning rod 31, so that the rubber stoppers in the open area 101 can be turned out and sorted out to avoid blocking the subsequent rubber stoppers. The sorting component 3 includes turning rods 31 arranged on the front side and the rear side of the pressure-sensitive detection rod 2, and a driving part 32 for driving the turning rods 31 to rotate. Openings 101 are provided on the slide plate 11 and the side plates 12 along the rotation track of the turning rods 31. By driving the turning rods 31 to pass through the openings 101 by the driving part 32, the rubber stoppers blocked by the pressure-sensitive detection rod 2 can be turned out.

[0032] It can be understood that when the rubber stopper contacts the pressure-sensitive detection rod 2, it acts on the pressure sensor to form a pressure-sensitive feedback. Then, in cooperation with the controller for signal processing, the driving part 32 on the sorting component 3 is controlled to rotate the turning rod 31. Among them, the controller can adopt a PLC controller, and the model can be S7-200. The reception and processing of the pressure-sensitive signal and the driving control of the driving part 32 are all conventional operation methods in the technical field and will not be elaborated here.

[0033] Specifically, the pressure-sensitive detection rod 2 includes a telescopic adjustment member 21, a pressure sensor 22, and a limit rod 23. The bottom of the telescopic adjustment member 21 is connected to the bottom of the slide plate 11. The pressure sensor 22 is arranged at the telescopic end of the telescopic adjustment member 21. The distance between the limit rod 23 and the side plate 12 is adjusted by the telescopic adjustment member 21, and this distance is the length that defines the diameter of the rubber plug that can pass through. Among them, the top of the limit rod 23 is connected to the pressure sensor 22. When the rubber plug contacts the limit rod 23, it will conduct to the pressure sensor 22 and detect the pressure value, and then feedback it to the controller.

[0034] Preferably, the driving member 32 is a stepping motor, which is convenient for controlling the rotation angle. The number of the turning rods 31 is four pairs. The four pairs of the turning rods 31 are arranged in a circular distribution on the output shaft of the stepping motor. The stepping motor drives the turning rods 31 to rotate by 90 degrees to separate the unqualified rubber plugs from the slideway 1. Among them, a pair of turning rods 31 includes two turning rods 31. The two turning rods 31 are respectively adjacent to the front side and the rear side of the limit rod 23 and correspond to two openings 101. The two openings 101 are also adjacent to the front side and the rear side of the limit rod 23. When the turning rods 31 rotate, they will pass through the openings 101 to complete the entire rotation process without being interfered by the slideway 1.

[0035] It can be understood that the pressure sensor 22 and the driving member 32 are both electrically connected to the PLC controller, and the PLC controller is used to control their actions.

[0036] In this embodiment, in order to sort out the rubber plugs with unqualified height before subsequent detection and avoid the unqualified rubber plugs with unqualified diameter being turned over and driving the rubber plugs above them to tilt, the rubber plug defective product detection and sorting mechanism further includes a limit plate 4 arranged on the side plate 12. The limit plate 4 is parallel to the slide plate 11 and is used to limit the height of the rubber plugs that can pass through. The limit plate 4 and the pressure-sensitive detection rod 2 are distributed from top to bottom along the direction of the slideway 1. Before entering the diameter detection range, the height is first limited, and under the shielding of the limit plate 4 at its top, it is avoided being driven to tilt by the unqualified rubber plugs that are turned out.

[0037] Furthermore, in order to avoid the unqualified rubber plugs with unqualified height from blocking the downward channel, the rubber plug defective product detection and sorting mechanism further includes a pushing component 5, which includes a driving motor 51 and a push rod 52. The push rod 52 is located at the top of the limit plate 4 and extends to the outside of the limit plate 4. The driving motor 51 is arranged on the side plate 12 through a bracket. The push rod 52 is connected to the output shaft of the driving motor 51. The driving motor 51 is used to drive the push rod 52 to make a circular motion on the top surface of the limit plate 4. By driving the driving motor 51 to drive the push rod 52 to rotate, the rubber plugs blocking on the limit plate 4 can be pushed to the side to avoid blocking the subsequent rubber plugs.

[0038] Preferably, the number of the push rods 52 is three, and the three push rods 52 are arranged on the output shaft of the driving motor 51 in a circumferential distribution.

[0039] Furthermore, in order to facilitate the smooth pushing away of the rubber plug with unqualified height and make it quickly detach from the slide 1, the side of the limit plate 4 close to the top of the slide plate 11 is provided with a downwardly inclined arc surface 401, and the rubber plug pushed to the side is guided to the side and below, and the slide plate 11 is provided with a discharge port 102, which is located at the tail end of the arc surface 401. After guiding it to the tail end of the arc surface 401, it can detach from the slide 1 from the discharge port 102.

[0040] It can be understood that at the limit plate 4, the plugs with too high height are sorted, and at the pressure sensing detection rod 2, the plugs with too long diameter are sorted to ensure the smoothness of the slideway 1, and some unqualified plugs are sorted out in advance to reduce the workload of subsequent quality inspections.

[0041] Furthermore, in order to avoid the influence of the thickness of the limiting plate 4 on the pushing away of the rubber plug, an extension rod 521 is provided at the bottom of the push rod 52, and the height of the extension rod 521 is equal to the thickness of the limiting plate 4, and a groove is opened on the limiting plate 4 corresponding to the rotation trajectory of the extension rod 521, thereby offsetting the influence of the thickness of the limiting plate 4 and avoiding the situation that the rubber plug that is not higher than the top of the limiting plate 4 is blocked and cannot be pushed by the push rod 52.

[0042] In this embodiment, in order to achieve a basic inclined sliding effect, one side of the slide plate 11 is inclined downwardly toward the side plate 12 at an angle of 5°.

[0043] In this embodiment, in order to facilitate the adjustment of the position of the limit rod 23, the telescopic adjustment member 21 includes a fixed seat 211, a sleeve 212, a sliding rod 213 and a limit bolt 214. The fixed seat 211 is fixedly connected to the slide plate 11 by bolts, and the sleeve 212 is arranged on the top of the fixed seat 211. The sliding rod 213 is slidably connected to the inner side of the sleeve 212. The limit bolt 214 is threadedly connected to one side of the sleeve 212 and passes through the sleeve 212 and is tightly attached to the sliding rod 213. By loosening the limit bolt 214 and sliding the sliding rod 213 along the sleeve 212, the position of the pressure sensor 22 and the limit rod 23 can be adjusted. When adjusted to the required position, the limit bolt 214 is rotated to press the sliding rod 213, which is convenient for adjustment.

[0044] The specific working process of the utility model: The rubber stoppers output from the vibrating disk sequentially fall to the top of the slideway 1, and along the inclined surface of the slide plate 11, lean against the side plate 12 and slide down; during the sliding process, first pass through the limit plate 4. If the height is too high, it will be blocked by the limit plate 4. Driven by the driving motor 51 to rotate the push rod 52, the rubber stopper will be pushed along the arc surface 401 to the blanking port 102, and sorted out from the slideway 1; the rubber stoppers that normally pass through the limit plate 4 then slide down to the pressure sensing rod 2. If the diameter is too large, it will be blocked by the limit rod 23. Under the feedback of the pressure sensor 22, the driving motor 51 drives the turning rod 31 to turn out the unqualified rubber stopper from the slideway 1, and other rubber stoppers slide out from the bottom end of the slideway 1 to the next detection unit.

[0045] The entire working process ends, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0046] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the utility model should be covered within the protection scope of the utility model.
