Description

Technical Field

[0001] The invention relates to the technical field of vaccine packaging, and in particular to an over-rotation detection component of a rotary rod labeling machine. Background Art

[0002] An injection is a pharmaceutical preparation that has an injection solution pre-loaded into a syringe. When it is used, the packaging can be directly removed, and the syringe can be taken out for injection. One of the production links of an injection is to send a syringe pre-loaded with an injection solution but without a push rod and a push rod to a place through a conveying device, and then put the push rod into the syringe. Then, the push rod is installed into the syringe by a combination of rotation and pressure through a device that twists the push rod. Vaccine packaging is in this form.

[0003] In the current disposable vaccine syringe packaging production line, due to the strict requirements of disposable syringes on packaging, if the torque is too large, the packaging will be over-rotated, and the syringe will be scrapped and unusable. In traditional technology, the detection of whether the syringe is over-rotated is done by manual visual observation. However, manual inspection is not only time-consuming and labor-intensive, but also requires a large amount of manual labor and is prone to fatigue, which will lead to errors in visual observation. In addition, although some products are over-rotated, the degree of over-rotation is very small, which cannot be detected manually.

[0004] In order to solve the drawbacks of manual sorting, the present invention proposes a technical solution to solve the drawbacks of manual sorting through automated detection means and improve the accuracy of detection. Summary of the invention

[0005] In order to solve the above problems, the present invention discloses an over-rotation detection component for a rotary rod labeling machine. The technical solution of the present invention is implemented as follows:

[0006] An over-rotation detection assembly for a rotary rod labeling machine comprises a fixing member, an upper end detection mechanism and a lower end detection mechanism;

[0007] The upper end detection mechanism is used to detect the height of the push rod of the syringe;

[0008] The lower end detection mechanism is used to detect the liquid level height in the syringe barrel of the syringe;

[0009] The upper end detection mechanism is arranged at the upper section of the fixing member;

[0010] The lower end detection mechanism is arranged at the lower section of the fixing member;

[0011] A discharge channel for the discharge of the syringe is arranged between the upper end detection mechanism and the lower end detection mechanism.

[0012] Preferably, the upper end detection mechanism includes a first detection device and a second detection device;

[0013] The lower end detection mechanism includes a third detection device and a fourth detection device;

[0014] The distance between the first detection device and the second detection device is greater than the diameter of the plunger of the syringe;

[0015] The distance between the third detection device and the fourth detection device is greater than the diameter of the syringe barrel of the syringe.

[0016] Preferably, the first detection device, the second detection device, the third detection device and the fourth detection device are all photoelectric sensors.

[0017] Preferably, a scale is provided on the fixing member.

[0018] Preferably, the fixing member comprises a first fixing bracket and a second fixing bracket;

[0019] The first detection mechanism is fixed on the first fixing bracket;

[0020] The second detection mechanism is fixed on the second fixing bracket.

[0021] Preferably, the fixing member further comprises a first tightening screw and a second tightening screw;

[0022] The first tightening screw is used to fix the first detection mechanism to the first fixing bracket, and the second tightening screw is used to fix the second detection mechanism to the second fixing bracket.

[0023] Preferably, the fixing member further comprises a first fixing screw and a second fixing screw;

[0024] The first fixing screw and the second fixing screw are used to fix the scale on the fixing member.

[0025] Preferably, the fixing member is a columnar structure.

[0026] The present invention solves the drawbacks of manual sorting. The assembled syringes are inspected by two sets of upper and lower detection mechanisms. The upper detection mechanism detects the height of the push rod to ensure that it is screwed in place, and the lower detection mechanism detects the liquid level of the syringe to ensure that the liquid level is normal. Double detection ensures that the syringe is assembled in place to prevent problems such as missed detection and wrong detection. In addition, the present invention can accurately adjust the height and position of the upper detection mechanism and the lower detection mechanism by a scale and tightening screws, and can adapt to the detection of syringes of different specifications.

[0046] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Unless otherwise defined, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specific implementation methods are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" in the specification and claims of the present invention and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0048] In the description of the specific implementation methods of the present invention, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present invention, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0049] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.

[0050] In the description of the embodiments of the present invention, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in the present invention generally indicates that the associated objects before and after are in an "or" relationship.

[0051] Throughout the present invention, numerical values ​​represent approximate measures or limits of ranges to cover minor deviations from given values ​​as well as embodiments with about the values ​​mentioned and embodiments with the exact values ​​mentioned. Except for the working examples provided at the end of the detailed description, all numerical values ​​of parameters (e.g., amounts or conditions) in this specification (including the appended claims) should be understood to be modified by the term "about" in all cases, regardless of whether "about" actually appears before the numerical value. "About" indicates that the stated numerical value allows some minor imprecision (close to the exact value of the value to some extent; approximately or reasonably close to the value; almost). If the imprecision provided by "about" is not otherwise understood in this ordinary sense in the art, "about" as used in the present invention at least indicates the variation that can be produced by the ordinary methods of measuring and using such parameters. For example, "about" may include a variation of less than or equal to 5%, optionally less than or equal to 4%, optionally less than or equal to 3%, optionally less than or equal to 2%, optionally less than or equal to 1%, optionally less than or equal to 0.5%, and in some aspects, optionally less than or equal to 0.1%.

[0052] Additionally, disclosure of ranges includes disclosure of all values ​​within the entire range and further divided ranges, including endpoints and sub-ranges given for such ranges.

[0053] In the current disposable vaccine syringe packaging production line, due to the strict requirements of disposable syringes on packaging, if the torque is too large, the packaging will be over-rotated, and the syringe will be scrapped and unusable. In traditional technology, the detection of whether the syringe is over-rotated is done by manual visual observation. However, manual inspection is not only time-consuming and labor-intensive, but also requires a large amount of manual labor and is prone to fatigue, which will lead to errors in visual observation. In addition, although some products are over-rotated, the degree of over-rotation is very small, which cannot be detected manually.

[0054] In order to solve the drawbacks of manual sorting, the present invention proposes a technical solution, which solves the drawbacks of manual sorting through automated detection means and improves the accuracy of detection. The technical solution of the present invention is implemented as follows:

[0055] An over-rotation detection assembly for a rotary rod labeling machine comprises a fixing member, an upper end detection mechanism and a lower end detection mechanism;

[0056] The upper end detection mechanism is used to detect the height of the push rod of the syringe;

[0057] The lower end detection mechanism is used to detect the liquid level height in the syringe barrel of the syringe;

[0058] The upper end detection mechanism is arranged at the upper section of the fixing member;

[0059] The lower end detection mechanism is arranged at the lower section of the fixing member;

[0060] A discharge channel for the discharge of the syringe is arranged between the upper end detection mechanism and the lower end detection mechanism.

[0061] The present invention realizes double detection of the assembled syringe through the upper end detection mechanism and the lower end detection mechanism. The upper end detection mechanism is used to detect the height of the push rod. If the height of the push rod is lower than the set value, it proves that the syringe is over-rotated. If the height of the push rod exceeds the set value, it proves that the syringe is under-rotated. The lower end detection mechanism is used to detect the liquid level height of the syringe in the needle cap and whether liquid appears at the bottom of the needle cap. If liquid appears in the needle cap, it proves that there is leakage and the syringe is waste. If the liquid height does not meet the set value, it proves that the syringe is not properly assembled.

[0062] The present invention realizes automated syringe assembly detection, solves various drawbacks of manual sorting, has high efficiency and good detection effect.

[0063] In some embodiments, the upper detection mechanism includes a first detection device and a second detection device;

[0064] The lower end detection mechanism includes a third detection device and a fourth detection device;

[0065] The distance between the first detection device and the second detection device is greater than the diameter of the plunger of the syringe;

[0066] The distance between the third detection device and the fourth detection device is greater than the diameter of the syringe barrel of the syringe.

[0067] The present invention detects the front and rear heights of the push rod of the syringe by means of a first detection device and a second detection device. If the detection heights of the first detection device and the second detection device are different, it proves that the syringe is assembled tilted. If the heights are the same and consistent with the set value, it proves that the push rod height is correct.

[0068] The present invention detects the front and rear liquid levels of the syringe barrel of the syringe by the third detection device and the fourth detection device. If the liquid level heights are different, it proves that the syringe is tilted and not vertically assembled, and there may be an assembly problem. If the liquid level heights are the same and consistent with the set value, it proves that the liquid level height is correct.

[0069] In some specific embodiments, the first detection device, the second detection device, the third detection device and the fourth detection device are all photoelectric sensors.

[0070] Photoelectric sensors have the advantages of high precision, fast response, and non-contact, and can measure many parameters. The sensor has a simple structure and flexible and diverse forms, and is more suitable for the application scenarios of the present invention.

[0071] In some embodiments, a scale is provided on the fixing member.

[0072] The function of the scale is to more intuitively display the push rod height, liquid level height, etc. of the currently assembled syringe. The height and relative distance of the upper detection mechanism and the lower detection mechanism can also be set more accurately by reference to the scale.

[0073] In some embodiments, the fixing member includes a first fixing bracket and a second fixing bracket;

[0074] The first detection mechanism is fixed on the first fixing bracket;

[0075] The second detection mechanism is fixed on the second fixing bracket.

[0076] In the present invention, the heights of the first detection mechanism and the second detection mechanism are adjustable. The specific adjustment method is: determine the installation height by a scale, and fix the heights of the first detection mechanism and the second detection mechanism by a first fixing bracket and a second fixing bracket.

[0077] In some specific embodiments, the fixing member further comprises a first tightening screw and a second tightening screw;

[0078] The first tightening screw is used to fix the first detection mechanism to the first fixing bracket, and the second tightening screw is used to fix the second detection mechanism to the second fixing bracket.

[0079] The invention realizes height adjustment of the second detection mechanism and the second detection mechanism by tightening the screws. When the height needs to be adjusted, the first tightening screw and the second tightening screw are loosened outward, and then after the height of the first detection mechanism and the second detection mechanism is adjusted, the first tightening screw and the second tightening screw are tightened inward. The structure is simple, easy to operate, and the height adjustment is more accurate after being matched with a scale.

[0080] In some embodiments, the fixing member further comprises a first fixing screw and a second fixing screw;

[0081] The first fixing screw and the second fixing screw are used to fix the scale on the fixing member.

[0082] The invention realizes installation and disassembly of the scale by means of the first fixing screw and the second fixing screw, has a simple structure and is easy to operate.

[0083] In some specific embodiments, the fixing member is a columnar structure.

[0084] The embodiments of the present invention will be described in more detail below by way of examples. It should be noted that the embodiments of the present invention are not limited to these examples.
