Description

Technical Field

[0001] The invention relates to the technical field of vaccine packaging, and in particular to a high-precision labeling head of a rotary rod labeling machine. Background Art

[0002] An injection is a drug 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 the syringe pre-loaded with injection solution but without a push rod and the push rod to a place through a conveying device, and then screw 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 screws the push rod. Vaccine packaging is in this form.

[0003] In addition to screwing the plunger into the barrel, the disposable syringe assembly process also includes attaching the label to the barrel.

[0004] Currently, for automatic labeling on vaccine packaging, a single motor drive is used in conjunction with a clamping device to straighten and move the labeling paper. The problem caused by this is that there is a large tension between the clamping device before labeling and the motor shaft after labeling, which can easily tear the labeling paper. Secondly, due to the excessive tension, the labeling paper sometimes cannot leave with the rotation of the driving wheel. The part of the labeling paper left in the system will increase the length of the labeling paper between the clamping device and the motor shaft and cannot be straightened, resulting in labeling errors.

[0005] The present invention proposes a new high-precision labeling head, which is driven front and back by dual servo motors to ensure that the label movement distance is consistent during label feeding, label pulling and paper recycling.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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%.

[0091] 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.

[0092] Currently, for automatic labeling on vaccine packaging, a single motor drive is used in conjunction with a clamping device to straighten and move the labeling paper. The problem caused by this is that there is a large tension between the clamping device before labeling and the motor shaft after labeling, which can easily tear the labeling paper. Secondly, due to the excessive tension, the labeling paper sometimes cannot leave with the rotation of the driving wheel. The part of the labeling paper left in the system will increase the length of the labeling paper between the clamping device and the motor shaft and cannot be straightened, resulting in labeling errors.

[0093] The present invention proposes a new high-precision labeling head, which is driven by dual servo motors to ensure that the label movement distance is consistent during label feeding, label pulling and paper recycling, and the dual servo drive greatly reduces the driving force of the two front and rear servo motors, thereby reducing the risk of the label paper being damaged. The high-precision labeling head includes a rotary rod labeling unit, a push-pull adjustment head unit and a thermal transfer unit. The rotary rod labeling unit includes a paper supply tray, a brake mechanism, a label supply mechanism, a peeling plate, a label pulling mechanism, a paper collection mechanism and an adjustment mechanism; the label supply mechanism and the label pulling mechanism both include a diamond grinding wheel driven by a servo motor and a rubber roller matched with the diamond grinding wheel.

[0094] The present invention creatively sets the label supply mechanism to be driven by a servo motor, and forms a labeling system with a dual servo synchronous drive with the servo motor of the label pulling mechanism. Through the front and rear synchronous servo drive, the front and rear moving distances of the label paper are ensured to be the same, thereby ensuring the accuracy of labeling. In addition, since the front and rear dual servos drive the label paper to move, the motor located after the labeling link no longer needs to provide a large pulling force, thereby ensuring that the label paper will not break due to excessive stress.

[0095] In some embodiments, the rotary rod labeling unit further includes a paper supply buffer; the paper supply buffer is arranged on one side of the label supply mechanism; the paper supply buffer includes a swing roller, an auxiliary roller, a swing plate, a rocker arm tension spring and a rocker arm tension spring fixing column;

[0096] One end of the rocker arm tension spring is fixed on the rocker arm tension spring fixing column, and the other end is connected to the swing plate, and the swing roller is swingably arranged on one end of the swing plate.

[0097] Since labeling and label feeding are intermittent, in order to ensure that the stress on the label paper does not change significantly at the beginning and end of the production cycle, that is, when label feeding is stopped and restarted, the present invention provides a certain buffering force through paper supply buffering, so that the stress on the label paper will change slowly at this moment instead of changing instantly.

[0098] In some preferred embodiments, the rotary rod labeling unit further includes a paper receiving buffer;

[0099] The paper receiving buffer is arranged on one side of the paper receiving mechanism;

[0100] The paper receiving buffer comprises a plastic roller and a spring.

[0101] The function of the paper collection buffer is basically the same as that of the paper supply buffer, and the structure is basically the same. Its purpose is to provide a buffer to prevent the label paper from being torn. The difference is that the label paper of the paper supply buffer is located between the label supply mechanism and the thermal transfer unit, and the label paper of the paper collection buffer is located between the thermal transfer unit and the paper collection mechanism. The two act on different label papers, but combined with the synchronous drive of the dual servo motors, it can more effectively ensure that the label paper will not be torn, while ensuring the labeling accuracy.

[0102] In some embodiments, the rotary rod labeling unit further includes a first detection mechanism;

[0103] The first detection mechanism is arranged between the thermal transfer unit and the label supply mechanism;

[0104] The first detection mechanism is used to detect the moving distance of the label provided by the label supply mechanism.

[0105] In the present invention, the first detection mechanism is connected to the control center for communication. When the first detection mechanism detects an error in the moving distance of the label paper, the signal is transmitted to the control center, and the control center controls the labeling head to stop running to prevent the subsequent label delivery error from further increasing.

[0106] In some preferred embodiments, the rotary rod labeling unit further includes a second detection mechanism;

[0107] The second detection mechanism is disposed between the thermal transfer unit and the peeling plate;

[0108] The second detection mechanism is used to detect the moving distance of the label given by the thermal transfer unit.

[0109] The second detection mechanism has the same function as the first detection mechanism, and its purpose is also to detect the moving distance of the label paper. The two detection mechanisms cooperate with two servo motors to synchronously control the movement of the detection label paper, further ensuring the moving accuracy of the label paper.

[0110] In some embodiments, the rotary rod labeling unit further comprises a stock photoelectric;

[0111] The stock photoelectric device is arranged on one side of the paper supply tray;

[0112] The photoelectric device is used to detect labels in the paper supply tray.

[0113] The photoelectric indicator is used to detect whether there is any label paper in the paper supply tray. When there is no label paper, the photoelectric indicator will send an alarm signal to the control center, and the control center will control the shutdown.

[0114] The embodiments of the present invention will be described in more detail below through examples. It should be noted that the embodiments of the present invention are not limited to these examples.

[0115] Example

[0116] In a specific embodiment, Figure 1-2 As shown, a high-precision labeling head of a rotary rod labeling machine includes a rotary rod labeling unit 1, a push-pull adjustment head unit 2 and a thermal transfer unit 3. The rotary rod labeling unit 1 includes a paper supply tray 1.1, a brake mechanism 1.2, a label supply mechanism 1.3, a paper supply buffer 1.4, a first detection mechanism 1.5, a second detection mechanism 1.6, a peeling plate 1.7, a label pulling mechanism 1.8, a paper collection buffer 1.9, a paper collection mechanism 1.10, a stock photoelectric 1.11 and an adjustment mechanism 1.12; the label supply mechanism 1.3 and the label pulling mechanism 1.8 both include a diamond grinding wheel driven by a servo motor and a rubber roller matching the diamond grinding wheel.

[0117] like Figure 3As shown, the paper supply buffer 1.4 is arranged on one side of the label supply mechanism 1.3; the paper supply buffer 1.4 comprises a swing roller 1.4.1, an auxiliary roller 1.4.2, a swing plate 1.4.3, a rocker arm tension spring 1.4.4 and a rocker arm tension spring fixing column 1.4.5;

[0118] One end of the rocker arm tension spring 1.4.4 is fixed to the rocker arm tension spring fixing column 1.4.5, and the other end is connected to the swing plate 1.4.3. The swing roller 1.4.1 is swingably arranged at one end of the swing plate 1.4.3.

[0119] The swing roller 1.4.1 is tightened by the rocker arm tension spring 1.4.4. Its first function is to cooperate with the auxiliary roller 1.4.2 to tighten the label paper. In addition, since one end of the rocker arm tension spring 1.4.4 is fixed and the other end is not fixed, the swing roller 1.4.1 can swing left and right. In this way, when the two servo motors move, the instantaneous change in tension on the label paper will act on the swing roller 1.4.1, and the swing of the swing roller 1.4.1 will cause a slight change in the tension of the label paper, so that the tension on the label paper will change within a certain range. Such a buffer can ensure that the label paper will not break due to excessive instantaneous tension changes.

[0120] The paper receiving buffer 1.9 is arranged on one side of the paper receiving mechanism 1.10; the structure of the paper receiving buffer 1.9 is similar to the paper feeding buffer structure.

[0122] The second detection mechanism 1.6 is arranged between the thermal transfer unit 3 and the peeling plate 1.7; the second detection mechanism 1.6 is used to detect the moving distance of the label given by the thermal transfer unit 3.

[0123] The photoelectric detector 1.11 is arranged at one side of the paper supply tray 1.1; the photoelectric detector 1.11 is used to detect the labels in the paper supply tray 1.1.

[0124] like Figure 4 As shown, the adjustment mechanism 1.12 includes an adjustment hand wheel 1.12.1, a first digital display 1.12.2, a lifting adjustment seat 1.12.3, a lifting slide rod 1.12.4, a lifting slide seat 1.12.5, a first adjustment screw 1.12.6, a lifting fixed seat 1.12.7, a rectangular tooth rod 1.12.8, a rectangular nut 1.12.9 and a washer 1.12.10;

[0126] The adjustment mechanism 1.12 is used to adjust the height of the rotary rod labeling unit 1. The specific adjustment process is:

[0127] Turn the adjustment hand wheel 1.12.1, the first adjustment screw 1.12.6 rotates, and the lifting slide 1.12.5 is driven to move on the lifting slide rod 1.12.4 through the thread transmission, and the height of the rectangular tooth rod 1.12.8 is adjusted on the other side, so that the lifting fixed seat 1.12.7 is lifted and lowered. The lifting and lowering of the lifting fixed seat 1.12.7 is the lifting and lowering of the rotary rod labeling unit.

[0128] like Figure 5 As shown, the push-pull adjustment head unit 2 includes a first five-star knob 2.1, a second digital display 2.2, a second adjustment screw 2.3, a host adjustment seat 2.4, a chrome-plated rod 2.5 and a thrust ball bearing 2.6; the first five-star knob 2.1 is arranged at the first end of the second adjustment screw 2.3, the thrust ball bearing 2.6 is arranged at the second end of the second adjustment screw 2.3, the chrome-plated rod 2.5 is arranged parallel to the second adjustment screw 2.3, the host adjustment seat 2.4 is slidably arranged on the chrome-plated rod 2.5, and the bottom of the host adjustment seat 2.4 is provided with a thread that cooperates with the second adjustment screw 2.3;

[0129] The push-pull adjustment head unit 2 is used to adjust and fix the position of the rotary rod labeling unit 1. The specific adjustment process is: turning the first five-star knob 2.1 drives the second adjustment screw 2.3 to rotate, and drives the main machine adjustment seat 2.4 to slide on the chrome-plated rod 2.5 through thread transmission, thereby realizing the position adjustment of the rotary rod labeling unit 1.

[0130] like Figure 6As shown, the thermal transfer unit 3 includes a second five-star knob 3.1, a third digital display 3.2, a third adjusting screw 3.3, a first slide bar 3.4, a plane slide seat 3.5, a third five-star knob 3.6, a fourth digital display 3.7, a vertical slide seat 3.8, a fourth adjusting screw 3.9, a fixed base 3.10, and a second slide bar 3.11;

[0131] The planar slide 3.5 is slidably arranged on the first slide rod 3.4, the third adjusting screw 3.3 passes through the planar slide 3.5, and the planar slide 3.5 is provided with a thread that cooperates with the third adjusting screw 3.3. The second five-star knob 3.1 is arranged on one end of the third adjusting screw 3.3.

[0132] The position of the thermal transfer unit is adjusted as follows:

[0133] By turning the second five-star knob 3.1, the third adjusting screw 3.3 drives the plane slide 3.5 to slide on the first slide rod 3.4, thereby realizing plane movement, and by turning the third five-star knob 3.6, the fourth adjusting screw 3.9 drives the vertical slide 3.8 to slide on the second slide rod 3.11, thereby realizing vertical movement.

[0134] In this embodiment, the first digital display, the second digital display, the third digital display and the fourth digital display are all used to display the pitch change.

[0135] The specific workflow of this embodiment is as follows:

[0136] The label on the paper supply tray 1.1 is wound around the brake mechanism 1.2 to the label supply mechanism 1.3. The label supply mechanism 1.3 is directly connected to the diamond grinding wheel by a servo motor, and there is a rubber wheel next to it to squeeze and generate friction to drive the label forward. When the label moves more or less, there is a label supply buffer 1.4 to adjust it. The label supply buffer 1.4 is composed of plastic rollers and springs. When the label passes through the first detection mechanism 1.5, the moving distance is read and it continues to move forward. When it reaches the thermal transfer unit 2, the information is printed on the label. When it reaches the second detection mechanism 1.6, the moving distance of the label is read again. Finally, the label is peeled off and attached to the material through the peeling plate 1.7. When it senses that the material has reached the labeling station, the label pulling mechanism 1.8 pulls the label so that the label is detached from the peeling plate 1.7. The bottom paper with the label attached goes to the paper receiving buffer 1.9, and its mechanism is composed of linear guides. When the bottom paper on the paper receiving buffer 1.9 reaches a certain amount, the paper receiving mechanism 1.10 starts to work to collect the paper. The paper collection mechanism 1.10 is composed of a servo motor directly connected to a turntable. When there is no label on the paper supply tray 1.1, the inventory photoelectric 1.11 will alarm and stop.

[0137] When the material arrives, the label pulling mechanism 1.8 and the label supply mechanism 1.3 work simultaneously to ensure the label movement accuracy and make the labeling accuracy higher. The label pulling mechanism 1.8 and the label supply mechanism 1.3 are both composed of a servo motor directly connected to the diamond grinding wheel, and a rubber wheel is squeezed beside it.

[0138] 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 substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
