Description

Technical Field

[0001] The utility model relates to the technical field of vaccine packaging, in particular to a labeling wheel attachment mechanism for a rotary rod labeling machine. Background Art

[0002] An injectable is a pharmaceutical preparation that comes pre-filled with an injectable solution into a syringe. When used, the packaging can be removed, the syringe can be taken out, and the injection can be performed. One step in the production of an injectable involves delivering a syringe pre-filled with the injectable solution but without a plunger to a separate location via a delivery device. The plunger is then placed into the syringe, and a screwing mechanism then uses a combination of rotation and pressure to force the plunger into the syringe. Vaccines are packaged in this manner.

[0003] After the vaccine is packaged, it is usually necessary to affix a label to the glass surface of the vaccine syringe. One approach is to transfer all products to the labeling equipment for labeling after assembly is completed, but this is time-consuming and labor-intensive, and there is a risk of vaccine damage during transportation; another approach is to directly integrate the labeling equipment into the screwing device, so that the labeling operation can be achieved at the same time as the assembly is completed, but this places high demands on the coordinated operation of various components, and the more complex the structure, the greater the possibility of errors in coordinated operation. The second approach often results in problems such as tilted labels and wrinkled labels.

[0004] In order to solve the problems that often occur in the second method, the utility model proposes a technical solution, which achieves complete fitting of the label and the syringe, has a simple structure and strong applicability. Utility Model Content

[0042] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0043] 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 description and claims of the present invention and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions.

[0044] In the description of the specific embodiments of this utility model, the technical terms "first" and "second" are used only to distinguish different objects and should not be understood to indicate or imply relative importance or implicitly indicate the number, specific order, or primary and secondary relationship of the technical features indicated. In the description of the embodiments of this utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0045] References to "embodiments" in this disclosure mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0046] In the description of the embodiments of the present invention, the term "and / or" is merely a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in the present invention generally indicates that the related objects are in an "or" relationship.

[0047] Throughout this disclosure, numerical values represent approximate measures or limits of ranges to encompass minor deviations from a given value, as well as embodiments having approximately the stated value and embodiments having the exact value stated. Except for the working examples provided at the end of the detailed description, all numerical values for parameters (e.g., amounts, or conditions) in this specification (including the appended claims) should be understood as being modified in all instances by the term "about," regardless of whether "about" actually appears before the numerical value. "About" indicates that the stated numerical value allows for some minor imprecision (somewhat close to the exact value of the stated value; approximately or reasonably close to the stated value; nearly). If the imprecision provided by "about" is not otherwise understood in this ordinary sense in the art, "about," as used herein, at least indicates the variation that can occur due to ordinary methods of measuring and using such parameters. For example, "about" may encompass variations 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 certain aspects, optionally less than or equal to 0.1%.

[0048] Additionally, disclosure of ranges includes disclosure of all values within the entire range and further divided ranges, including endpoints and sub-ranges stated for such ranges.

[0049] After the vaccine is packaged, it is usually necessary to affix a label to the glass surface of the vaccine syringe. One approach is to transfer all products to the labeling equipment for labeling after assembly is completed, but this is time-consuming and labor-intensive, and there is a risk of vaccine damage during transportation; another approach is to directly integrate the labeling equipment into the screwing device, so that the labeling operation can be achieved at the same time as the assembly is completed, but this places high demands on the coordinated operation of various components, and the more complex the structure, the greater the possibility of errors in coordinated operation. The second approach often results in problems such as tilted labels and wrinkled labels.

[0050] In order to solve the above problems, the utility model discloses a labeling wheel attachment mechanism for a rotary rod labeling machine, which includes a main frame, a labeling drive unit, a main shaft, a first synchronous pulley, a first synchronous belt, a second synchronous pulley, a third synchronous pulley and a second synchronous belt;

[0051] The pressure mark driving unit is arranged at the lower part of the main frame, the pressure mark driving unit is connected to the main shaft, the main shaft is connected to the first synchronous pulley, the first synchronous pulley is connected to the second synchronous pulley through the first synchronous belt, the second synchronous pulley is coaxially connected to the third synchronous pulley, and the second synchronous belt is wound around the third synchronous pulley;

[0052] The second synchronous belt is arranged on one side of the rod twisting device.

[0053] In this utility model, the labeling drive unit is used to drive the main shaft to rotate, which in turn drives the first and second synchronous pulleys to rotate. The second synchronous belt drives the third synchronous pulley to rotate, and the second synchronous belt wrapped around the third synchronous pulley begins to move in response to the rotation of the third synchronous pulley. The second synchronous belt rotates in the opposite direction to the syringe on the screwing mechanism. The relative rotation and friction between the two flattens the label attached to the syringe.

[0054] In some embodiments, further comprising a swing assembly;

[0055] The swing assembly includes a swing drive unit;

[0056] The swing driving unit is connected to the main frame.

[0057] In the utility model, the swing assembly is used to control the main frame to swing out when changing the label or performing maintenance, leaving space for convenient maintenance, changing the label, and handling of faults.

[0058] In some embodiments, a limit block is further included;

[0059] The limit block is arranged on the main frame and is located in front of the marking station.

[0060] In the present invention, when the second synchronous belt is rolling and compacting the label, when it approaches the pre-filled syringe, in order to control the pre-tightening force, a limit block is set to control the pressure against the pre-filled syringe.

[0061] The stopper adjusts the distance between the label-pressing wheel attachment and the screwing mechanism. One function is to prevent the attachment from getting too close or too far from the screwing mechanism. If they are too close, the syringe will be squeezed too hard as it passes between them, potentially breaking the bottle. If they are too far, the friction between the syringe and the second timing belt decreases, preventing the label from being firmly pressed. A third function is to push the attachment away from the label-pressing wheel, facilitating repair or replacement of components.

[0062] In some specific implementations, the pressure mark driving unit is a servo motor.

[0063] The servo motor has precise control and can more easily match the production rhythm of the rod twisting device.

[0064] In some embodiments, further comprising a coupling;

[0065] The pressure standard driving unit is connected to the main shaft through a coupling.

[0066] In some embodiments, the swing driving unit is a solenoid valve cylinder.

[0067] In some embodiments, the limiting block is made of rubber.

[0068] Rubber is wear-resistant and elastic, which makes it more stable in controlling tension and has a longer service life.

[0069] The following examples will be used to more specifically describe the embodiments of the present invention. It should be noted that the embodiments of the present invention are not limited to these examples.

[0073] The swing cylinder 11 is connected to the main frame 12, and the rubber limit block 10 is set on the main frame 12 and located in front of the marking station.

[0074] In this embodiment, the servo motor 1 is connected to the main shaft 3 via a coupling 2 .

[0075] In this embodiment, the third synchronous pulley 7 and the second synchronous pulley 6 are connected by an inserting shaft.

[0076] The workflow of this embodiment is as follows:

[0077] This embodiment is driven by a servo motor 1 and is connected to a main shaft 3 attached to the marking wheel by a coupling 2. The main shaft 3 can drive the first synchronous belt 5 above to rotate and can also swing around its center.

[0078] The main shaft 3 rotates, driving the first synchronous pulley 4 to rotate. The first synchronous pulley 4 is connected to the second synchronous pulley 6 in the same plane by the first synchronous belt 5, so that the second synchronous pulley 6 follows the rotation, and then transmits the power to the third synchronous pulley 7 on the upper part through the coaxial transmission. The second synchronous belt 8 rotates to roll and compact the self-adhesive label affixed to the pre-filled syringe 9, and it must be ensured that the printed text on the label is clear and there is no wrinkle when rolling.

[0079] It should be pointed out that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
