Description

Technical Field

[0001] This utility model relates to the field of automatic labeling technology for pharmaceutical solvents, and in particular to a feeding device for a solvent labeling machine. Background Technology

[0002] Intravenous infusion solvents (such as styrofoam bags and soft bags) are important carriers for drug infusion, and their labeling information is one of the core elements to ensure medical safety. The label must accurately carry key data such as patient identity, drug name, dosage concentration, preparation time, and the person administering the prescription. Any missing information or identification error may lead to medication errors and endanger patient safety.

[0003] Traditional labeling processes rely heavily on manual operation. Medical staff need to print paper labels batch by batch, sort solvents based on experience, and manually position and paste them. The serial operation of manual sorting, positioning, and pasting is time-consuming and difficult to adapt to the parallel processing needs of large batches of solvents, becoming an efficiency bottleneck in the static mixing workflow. Furthermore, due to the soft and easily deformable nature of the solvent, displacement during transportation, or operator fatigue, labels may tilt, wrinkle, or become misaligned, affecting the rapid identification by scanning equipment and medical staff. When multiple departments and multiple batches of solvents are mixed and processed, the traditional visual classification-based operation mode is prone to problems such as specification confusion and label-solvent mismatch.

[0004] Therefore, providing a labeling device with high positioning accuracy and high labeling efficiency to meet the stringent requirements of static mixing centers is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model discloses a feeding device for a solvent labeling machine to solve the above-mentioned technical problems existing in related technologies.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] This application provides a feeding device for a solvent labeling machine. The feeding device includes a frame and a first conveyor line, a vision recognition module, a guiding module, and a control module mounted on the frame; wherein:

[0008] The visual recognition module is located at the upstream end of the first conveyor line, and the visual recognition module is used to identify the first label on the solvent.

[0009] The guiding module is provided corresponding to the first conveying line, and the guiding module is configured to position the solvent and guide the solvent to move along the first conveying line.

[0010] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0011] The solvent labeling and applicator of this application has a feeding device. After the operator places the solvent on the first conveyor line, the visual recognition module at the upstream end of the first conveyor line can identify the first label on the solvent. The first label can be an original manufacturer's label, which can include basic information such as the name, specifications, batch number, and expiration date of the drug in the solvent. This is original data that cannot be tampered with. After the data is compared with the database information, the control module can control the operation of the first conveyor line and hand over the solvent to the subsequent labeling station to affix the second label. The second label can be a medical order information label, which can include medical order information such as dosage, preparation method, administration method, administration rate, and storage method, providing guidance for patients. This method not only realizes automated solvent feeding but also effectively avoids drug information confusion caused by human error or data entry errors, ensuring the accuracy of solvent information from the source and meeting the strict compliance requirements of drug production and distribution. The automated and efficient solvent feeding process can process more solvent per unit time, meeting the needs of the compounding center. Attached Figure Description

Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] The following is in conjunction with the appendix Figures 1 to 6 The feeding device of the solvent labeling machine provided in this application will be described in detail through specific embodiments and application scenarios.

[0024] Please see Figure 1 , Figure 2 and Figure 3This application discloses a feeding device for a solvent labeling machine, which is used for feeding the solvent labeling machine. The feeding device for the solvent labeling machine includes a frame 1200, a first conveyor line 100, a vision recognition module 300, a guide module 400, and a control module (not shown in the figure). The frame 1200 is the basic component of the feeding device for the solvent labeling machine, and can provide an installation foundation for the first conveyor line 100, the vision recognition module 300, and the guide module 400. The first conveyor line 100, the vision recognition module 300, the guide module 400, and the control module are all located on the frame. The solvent labeling machine includes the aforementioned feeding device, second conveyor line 200, label printing module 500, and pressing module 600. The first conveyor line 100 is located upstream of and connected to the second conveyor line 200. The label printing module 500 and pressing module 600 are both located on the conveying path of the second conveyor line 200. It is understood that the first conveyor line 100, second conveyor line 200, label printing module 500, and pressing module 600 are all electrically connected to a control module, which can control the operation of these components.

[0025] In this embodiment of the application, the solvent 1000 on the first conveyor line 100 can be conveyed to the second conveyor line 200. For example, both the first conveyor line 100 and the second conveyor line 200 can be belt conveyors. The solvent 1000 can be carried on the conveyor belts of the first conveyor line 100 and the second conveyor line 200. It should be noted that the first conveyor line 100 and the second conveyor line 200 each have an independent drive module. The drive module is electrically connected to the control module. The control module controls the conveying action of the first conveyor line 100 or the second conveyor line 200 by driving the drive module. For example, the drive module can include a motor, a drive roller and a driven roller. The conveyor belt is sleeved on the drive roller and the driven roller. The motor can be connected to the drive roller via a synchronous belt.

[0026] In the embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 5The visual recognition module 300 is located at the upstream end of the first conveyor line 100. The visual recognition module 300 is used to identify the first label of the solvent 1000 placed at the upstream end of the first conveyor line 100. The control module receives the image information of the first label captured by the visual recognition module 300 and compares it with the database information. For example, the first label can be the original manufacturer's identification label. The first label can include basic information such as the name, specifications, batch number, and expiration date of the medicine in the solvent 1000. It is original data that cannot be tampered with. When the label information of the first label passes the comparison, the control module can control the first conveyor line 100 to transfer the current solvent 1000 to the second conveyor line 200 for subsequent labeling and affixing actions. When the label information of the first label fails the comparison, the control module can control the first conveyor line 100 to be in a stopped state. At this time, the staff can remove the incorrectly placed current solvent 1000.

[0027] In this embodiment, the guide module 400 is set corresponding to the first conveyor line 100. When the worker places the solvent 1000 on the first conveyor line 100, the guide module 400 can play a certain role in pre-positioning the solvent 1000. After the label information of the first label is compared and passed, the first conveyor line 100 transports the current solvent 1000 to the second conveyor line 200. During this process, the guide module 400 can guide the solvent 1000 to be transported to the second conveyor line 200 in a relatively certain posture, thereby ensuring that the subsequent marking and labeling actions act on the determined part of the solvent 1000.

[0028] In this embodiment, the label printing module 500 is located on the conveying path of the second conveying line 200. The label printing module 500 can affix a second label to the solvent 1000 on the second conveying line 200. The second label can be a medical order information label. Specifically, the second label can include medical order information such as drug dosage, preparation method, administration method, administration rate and storage method, which can provide guidance for patients and adapt to the personalized treatment needs of different patients.

[0029] In this embodiment, the pressing module 600 is located on the conveying path of the second conveying line 200 and is downstream of the label printing module 500. After the label printing module 500 prints and pre-applies the second label to the solvent 1000, the subsequent pressing module 600 is configured to press down the second label to make the second label adhere tightly to the solvent 1000, thereby ensuring a stable bond between the second label and the solvent 1000.

[0030] Based on the above technical solution, in the solvent labeling and applicator of this application embodiment, after the operator places the solvent 1000 on the first conveyor line 100, the visual recognition module 300 at the upstream end of the first conveyor line 100 can identify the first label on the solvent 1000. After the image information of the first label captured by the visual recognition module 300 is compared with the database information, the control module can control the first conveyor line 100 to move and transport the solvent 1000 to the second conveyor line 200 for the affixing of the second label. The second label can be a medical order information label, which can include medical order information such as dosage, preparation method, administration method, administration speed and storage method, and can provide guidance for patients. This method can realize automated solvent feeding while effectively avoiding drug information confusion caused by human error or information entry errors, ensuring the accuracy of solvent information from the source, meeting the strict compliance requirements of drug production and circulation. The automated and efficient solvent feeding process can process more solvent per unit time, which can meet the needs of the compounding center.

[0031] In the embodiments of this application, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The visual recognition module 300 includes a camera 310, a light source 320, a bracket 330, and a transparent plate 340. The transparent plate 340 is located at the upstream end of the first conveyor line 100. When the worker places the solvent 1000, the solvent 1000 can be supported on the transparent plate 340. The light source 320 is located adjacent to the transparent plate 340 and is used to emit an illumination beam towards the transparent plate 340 to illuminate the solvent 1000, making the first label on the solvent 1000 clearly visible. The camera 310 is located on the bracket 330 and is positioned facing the transparent plate 340. Under the illumination provided by the light source 320, the first label on the solvent 1000 can be captured by the camera 310, thereby providing a basis for the control module to control the operation of the first conveyor line 100 and the second conveyor line 200.

[0032] In the embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 5The bracket 330 may include multiple rods, that is, the bracket 330 is a component assembled from multiple rods. For example, the bracket 330 includes a first rod 331, a second rod 332, a third rod 333, a first locking block 334, and a second locking block 335. The first rod 331, the second rod 332, and the third rod 333 are arranged perpendicularly in pairs. For example, the first rod 331 extends along the X-axis, the second rod 332 extends along the Y-axis, and the third rod 333... Extending along the Z-axis, the first locking block 334 is used to connect and fix the two rods, and the second locking block 335 is used to connect and fix the rod and the camera 310. For example, the lower end of the third rod 333 forms a bottom support. The first rod 331 can be connected to the third rod 333 through the first locking block 334, the second rod 332 can be connected to the first rod 331 through the first locking block 334, and the camera 310 can be connected to the second rod 332 through the second locking block 335.

[0033] In this embodiment, both the first locking clamp 334 and the second locking clamp 335 include a clamp body and a threaded connector. The clamp body has a through hole and a slot communicating with the through hole. The aforementioned rod is inserted into the through hole. The threaded connector can connect the portions of the clamp body on both sides of the slot. The operator can clamp and release the rod by rotating the threaded connector. It is understood that the first locking clamp 334 has two through holes to correspond to the connection of the two rods, while the second locking clamp 335 only needs one through hole. With this structure, the operator can adjust the position of the camera 310 in the X, Y, and Z axes, as well as the pitch angle of the camera 310, by loosening the corresponding threaded connector, so that the framing direction of the camera 310 can be accurately oriented towards the placement position of the solvent 1000, thereby ensuring the accuracy of the image of the first label.

[0034] In the embodiments of this application, please continue to refer to Figure 2 The number of first rods 331 and third rods 333 can be two, and the number of second rods 332 can be one. The components formed by connecting the first rods 331 and third rods 333 can be connected to the two ends of the second rods 332 in a symmetrical arrangement, thereby enhancing the structural stability of the entire support 330.

[0035] In some embodiments of this application, please refer to... Figure 1 and Figure 3The transparent plate 340 can be tilted relative to the first conveyor line 100, and the angle between the transparent plate 340 and the first conveyor line 100 is an obtuse angle, for example, within the range of 125°-135°. With this arrangement, on the one hand, when placing the solvent 1000, the worker can lean the solvent 1000 against the transparent plate 340, with the bottom of the solvent 1000 supported at the corner of the first conveyor line 100 and the transparent plate 340. Furthermore, the 125°-135° angle design can prevent the solvent 1000 from slipping under its own weight. In other words, the tilted transparent plate 340 can cooperate with the first conveyor line 100 to jointly... The solvent 1000 serves a positioning function, ensuring that its position and orientation are consistent each time it is placed. Once the position and orientation of the solvent 1000 are determined, the visual recognition module 300 does not need to search for the first label over a large area; it can directly focus on a specific area for recognition, significantly reducing the recognition time. Furthermore, for some solvent 1000 products, the first label printed on the solvent 1000 may exist in the curved or corner areas of the solvent 1000. Placing the solvent 1000 at an angle makes these areas more easily exposed, allowing the first label to be captured more accurately by the camera 310.

[0036] In the embodiments of this application, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The guiding module 400 includes two opposing guide members 410, which are distributed on both sides of the conveying direction of the first conveying line 100. When the operator places the solvent 1000 on the first conveying line 100, the solvent 1000 is located between and constrained by the two guide members 410. In the embodiments of this application, please continue to refer to... Figure 5 The guide component 410 includes a first guide section 411 and a second guide section 412 connected to each other. The first guide section 411 is set to correspond to the transparent plate 340, and the second guide section 412 is set to correspond to the first conveyor line 100. In this way, during the placement of the solvent 1000, the guide module 400 can position the solvent 1000 through the two opposing first guide sections 411, thereby ensuring the certainty of the placement position and posture of the solvent 1000. During the conveying process of the first conveyor line 100, the guide module 400 can guide and constrain the solvent 1000 through the two opposing second guide sections 412, thereby preventing the solvent 1000 from deviating or moving due to inertia, vibration or external interference during the conveying process. The movement of the solvent 1000 along a fixed trajectory can ensure precise docking with the second conveyor line 200, reduce the frequency of manual adjustment, and thus ensure the consistency of the second label attachment position.

[0037] For some embodiments of this application, please refer to Figure 4 and Figure 6 The first guide section 411 and the second guide section 412 can be separate structures, and the two can be connected and fixed by an L-shaped sheet connector 413. For example, the first guide section 411 and the second guide section 412 can be connected and fixed to the sheet connector 413 by a threaded connector. When it is necessary to adjust the tilt angle of the transparent plate 340 relative to the first conveying line 100 according to the appearance size of the solvent 1000, it is only necessary to select the corresponding L-shaped sheet connector 413 and reconnect it, thus avoiding the problem of increased production and manufacturing costs caused by setting multiple sets of guides 410.

[0038] For further technical solutions, please refer to Figure 1 , Figure 4 and Figure 5 At least one of the two guide members 410 is movable in a first direction, thereby making the spacing between the two guide members 410 adjustable in the first direction. The first direction is the distribution direction of the two guide members 410 and is perpendicular to the conveying direction of the first conveyor line 100. Figure 1 In this embodiment, the conveying direction of the first conveyor line 100 and the second conveyor line 200 is the X-axis direction, and the first direction is the Y-axis direction. For example, the distance between the two guide members 410 can be in the range of 58mm-138mm. By adjusting the distance between the two guide members 410, on the one hand, the two guide members 410 and the solvent 1000 have a better matching degree, avoiding excessively tight constraint of the guide members 410 which would cause friction and wear on the solvent 1000, and also avoiding excessively loose constraint of the guide members 410 which would cause large displacement of the solvent 1000. On the other hand, by adjusting the distance between the two guide members 410, the width range of 58mm-138mm allows the first conveyor line 100 to convey different types and sizes of solvent 1000 for labeling, avoiding the need to design a separate labeling device for each solvent 1000 product, greatly reducing equipment cost and design complexity, and improving the versatility of the feeding device of the solvent labeling machine of this application for multiple solvent 1000 products.

[0039] In optional embodiments of this application, the two guide members 410 can move synchronously towards or away from each other, thereby adjusting the distance between the two guide members 410. For example, the two guide members 410 can move towards or away from each other via a screw drive mechanism. Specifically, please refer to... Figure 4The guide module 400 may further include a motor 420, a bidirectional screw 430, a connecting block 440, and a guide rail 450. The bidirectional screw 430 and the guide rail 450 both extend along a first direction. The control module is electrically connected to the motor 420. The actuator of the motor 420 is connected to the bidirectional screw 430 to drive the bidirectional screw 430 to rotate. Two connecting blocks 440 are respectively sleeved on both ends of the bidirectional screw 430, and the two connecting blocks 440 are respectively slidably engaged with the guide rail 450. For example, the connecting block 440 can be a ball nut, and the connecting block 440 can be slidably engaged with the guide rail 450 through a slider, thereby ensuring the smooth movement of the connecting block 440. Two guide members 410 are respectively connected to one connecting block 440. When it is necessary to adjust the distance between the two guide members 410 to better adapt to the current solvent 1000 product, the rotation of the motor 420 can drive the bidirectional screw 430 to rotate, thereby causing the two connecting blocks 440 at both ends to move towards or away from each other, thus bringing the two guide members 410 closer or further apart in the first direction. Using a screw drive mechanism to adjust the distance between the two guide members 410 has the characteristics of high reliability, high adjustment accuracy, and high adjustment efficiency. Of course, in this embodiment, the guide module 400 can also achieve the adjustment of the distance between the two guide members 410 through various driving methods such as a gear and rack drive mechanism, a linear motor, or a synchronous belt drive mechanism; this application does not impose specific limitations on this.

[0040] Please see 5 and Figure 6 The label printing module 500 includes a first lifting mechanism 510, a substrate 520, a feeding roll 530, a printing engine 540, a receiving roll 550, and multiple guide rollers 560. The first lifting mechanism 510 and the substrate 520 are both disposed on the frame 1200, and the substrate 520 is movably disposed on the frame 1200 in the longitudinal direction. The first lifting mechanism 510 is connected to the substrate 520 to drive the substrate 520 to lift relative to the frame 1200. The substrate 520 provides a mounting base for the unloading roll 530, the printing engine 540, the take-up roll 550, and multiple guide rollers 560. The unloading roll 530, the printing engine 540, the take-up roll 550, and the multiple guide rollers 560 are all located on the substrate 520. The material strip released from the unloading roll 530 passes through the printing engine 540. After the printing engine 540 applies a label to the solvent 1000, the waste material of the strip is then wound onto the take-up roll 550. It should be noted that the multiple guide rollers 560 are distributed between the unloading roll 530 and the take-up roll 550 to provide a guiding path for the material strip. The multiple guide rollers 560 can be distributed upstream of the printing engine 540, downstream of the printing engine 540, or both upstream and downstream of the printing engine 540. This application embodiment does not impose specific limitations on this.

[0041] Based on the lifting and adjusting of the substrate 520 by the first lifting mechanism 510, the contact pressure between the printing engine 540 and the solvent 1000 can be controlled, avoiding wrinkles on the applied second label or scratches on the surface of the solvent 1000. This allows for compatibility with different materials such as glass packaging or soft bag packaging. Furthermore, depending on the different solvent materials and sizes, the spacing between the printing engines 540 can be adaptively adjusted via the first lifting mechanism 510, making the label printing module 500 versatile during labeling. In this embodiment, the first lifting mechanism can be a lead screw lifting mechanism, a synchronous belt lifting mechanism, a rack and pinion lifting mechanism, etc., without specific limitations.

[0042] In a further technical solution, the printing engine 540 can be arranged at an angle relative to the horizontal plane. For example, the angle of the printing engine 540 is in the range of 23°-30°, such as 25°. The lifting stroke of the first lifting mechanism 510 is in the range of 80mm-150mm, such as 100mm. With this setting, the inclined arrangement of the printing engine 540 allows the second label to contact the solvent 1000 in a "gradual" manner at a certain inclined angle, which can avoid wrinkles, bubbles, etc. This arrangement angle and lifting stroke can adapt to different solvent sizes, while having enough operating space for changing the label paper. The printed and peeled second label can accurately fall on the labeling position on the solvent 1000.

[0043] The second label affixed to the solvent 1000 by the printing engine 540 is in a flat state. However, the outer surface of the solvent 1000, such as that of a soft bag, is usually curved. That is to say, the second label affixed by the printing engine 540 only achieves partial pre-contact with the solvent 1000 and does not achieve stable adhesion between the second label and the solvent 1000. Based on this situation, in the embodiments of this application, the pressing module 600 is used to tightly adhere the second label to the solvent 1000.

[0044] For details, please continue to see Figure 5The bonding module 600 includes a second lifting mechanism and an elastic buffer. The second lifting mechanism is connected to the elastic buffer to drive the elastic buffer to press down the second label, so that the second label is tightly bonded to the solvent 1000. The selection and application of the second lifting mechanism will not be elaborated in this application. For example, the second lifting mechanism is a synchronous belt lifting mechanism. The second lifting mechanism is connected to a mounting plate. The elastic buffer can be a polymer elastomer or a high-resilience sponge. The elastic buffer can be attached to the mounting plate. When the second lifting mechanism drives the elastic buffer to descend and contact the second label, the elastic buffer adapts to the height difference of the solvent 1000 surface through elastic deformation, such as the curved surface of a soft bag packaging, to achieve complete contact between the second label and the solvent 1000 surface. Furthermore, the elastic buffer automatically adjusts the pressure applied to the second label through elastic deformation, so as to press the second label tightly to the solvent 1000 while avoiding damage to the solvent 1000.
