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.

[0045] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0046] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limitations of the present invention.

[0047] The object of the present invention is to provide a multi-row stick bag production system and method with filling and weighing functions, which can effectively improve the filling accuracy of stick bag products.

[0048] See also Figures 1 to 5 To achieve the above-mentioned objectives, the present invention provides a multi-row stick bag production system with filling and weighing functions, comprising a stick bag packaging machine 100, a filling mechanism 200, and a collating conveyor 300. The stick bag packaging machine 100 is provided with a filling station and a stick bag outlet. The stick bag packaging machine 100 is used to seal the filled stick bags to form stick package products 400. The filling mechanism 200 is provided with a filling channel 210 extending to the filling station. The filling channel 210 is used to fill the medicine into the stick bags located at the filling station. The collating conveyor 300 is docked with the stick bag outlet via a docking slide 500. The docking slide 500 is used to transfer the stick package products 400 from the stick bag outlet to the collating conveyor 300. The collating conveyor 300 is provided with a checkweigher station 310. The checkweigher station 310 is used to weigh the stick bags after being conveyed by the docking slide 500.

[0049] By integrating a strip bag packaging machine 100 equipped with a filling station, a filling mechanism 200 for drug filling, and a sorting conveyor 300 equipped with a checkweigher station 310 and docked with the strip bag packaging machine 100 via a docking slide 500 into a multi-row strip bag production system, the strip bag products 400 formed by filling and sealing the strip bags can be directly weighed by entering the checkweigher station 310. Based on the comparison between the weighing data of the strip bag products 400 and the preset weight range, the filling volume of the subsequent filling mechanism 200 can be flexibly adjusted, thereby effectively improving the filling accuracy of the strip bag products 400.

[0050] In one possible embodiment, the filling mechanism 200 includes a liquid storage tank, a plunger pump cavity 220, a liquid inlet 230, a liquid outlet 240, a rotary valve mechanism 250 and a plunger rod 260. The liquid storage tank is used to store the drug, which is a liquid; the plunger pump cavity 220 is provided with a receiving space; the cross-sectional shape of the receiving space can be, but is not limited to, a circle, and the size of the circular cross-section can be set according to actual needs. The liquid inlet 230 is connected to the receiving space; the liquid outlet 240 is connected to the receiving space. The rotary valve mechanism 250 is used to close the liquid inlet 230 when the liquid outlet 240 is connected to the filling channel 210, and the rotary valve mechanism 250 is also used to close the liquid inlet 230 when the liquid outlet 240 is connected to the outlet of the liquid storage tank; the plunger rod 260 is movably connected to the plunger pump chamber 220 to extract a preset filling amount of medicine when the liquid outlet 240 is closed, and to deliver the preset filling amount of medicine to the filling channel 210 for medicine filling when the liquid inlet 230 is closed.

[0051] Among them, the plunger pump cavity 220, the liquid inlet 230, the liquid outlet 240, the plunger rod 260 and the filling channel 210 all correspond to each other, so that the plunger rod 260 communicates with the independent liquid inlet 230 when pumping liquid, and communicates with the independent liquid outlet 240 when pushing liquid, and the medicine in the plunger pump cavity 220 is filled into a separate strip bag through the independent filling channel 210. By setting multiple groups of plunger pump cavities 220, liquid inlets 230, liquid outlets 240, plunger rods 260 and filling channels 210, it can be used for drug filling of multiple strip bags at the same time, thereby improving production efficiency. The plunger rod 260 can be a ceramic plunger rod 260, and multiple liquid outlets 240 can be connected to the same liquid storage tank through independent delivery pipes. Alternatively, a liquid storage tank can be added according to actual needs so that the liquid storage tank is used to supply liquid to a separate plunger pump cavity 220.

[0052] In one possible embodiment, the multi-column strip bag production system with filling and weighing functions also includes a PLC control system and an industrial computer data storage system. The filling mechanism 200 also includes a power source 270, a screw rod 280 that is transmission-connected to the output end of the power source 270, and a slider that is sleeved on the screw rod 280 and can move along the extension direction of the screw rod 280. The slider is connected to the plunger rod 260. When the power source 270 drives the screw rod 280 to rotate, it can drive the slider and the plunger rod 260 to move relative to the plunger pump chamber 220 to extract or push the drug. The power source 270 can be, but is not limited to, a servo motor. The servo motor drives the mechanical screw 280 to pump and push liquid through the plunger rod 260. The filling volume is controlled by the volume of the space within the plunger pump chamber 220. Specifically, the power source 270 controls the two extreme positions of the reciprocating movement of the plunger rod 260 within the space within the plunger pump chamber 220. Furthermore, the filling volume is controlled by the displacement parameters of the plunger rod 260 driven by the servo motor. These displacement parameters may include a baseline parameter and a deviation parameter. After filling, the stick packs 400 enter the checkweigher station 310 on the sorting conveyor 300 for individual bag weighing. The real-time weighing value is compared with the maximum and minimum set values. If the fill volume of three consecutive stick packs 400 is too low or too high, the corresponding servo motor deviation parameter is automatically adjusted via the PLC control system. The maximum and minimum set values ​​are related to the density of the filled product and can be set according to customer requirements. The weighing values ​​are stored in the industrial computer data storage system. Data can be queried by filtering functions such as production date, batch number, and specification, achieving effective management of weighing data. Abnormal weighing data can be checked in real time, and filling deviation factors can be analyzed in real time based on the data to effectively ensure product quality.

[0053] It should be noted that the accommodation space within the plunger pump chamber 220 can be configured as a cylindrical structure, with the plunger rod 260 reciprocating along the axis of the cylindrical structure. The weighing weight is equal to the product of density and volume. For the filling of the same drug, the density of the drug is a fixed value, and the volume of the drug is the volume of the accommodation space of the plunger pump chamber 220 when the plunger rod 260 moves relative to the plunger pump chamber 220 to complete drug extraction. This volume is related to the product of the circular cross-sectional area of ​​the accommodation space of the plunger pump chamber 220 and the height of the accommodation space perpendicular to the cross-sectional area. The cross-sectional area of ​​the accommodation space of the plunger pump chamber 220 is known data, and the height of the accommodation space perpendicular to the cross-sectional area is related to the stroke of the plunger rod 260.

[0054] (1);

[0055] Wherein, M is the mass of the drug in the stick-packed product 400 , ρ is the density of the drug in the stick-packed product 400 , and V is the volume of the drug in the stick-packed product 400 .

[0056] (2);

[0057] Wherein, R is the cross-sectional radius of the plunger pump cavity 220, H is the height of the drug in the plunger pump cavity 220 in the axial direction of the plunger pump cavity 220 when the plunger rod 260 moves relative to the plunger pump cavity 220 to complete drug extraction (displacement parameter of the plunger rod 260), and V is the volume of the drug in the stick pack product 400.

[0058] It can be deduced from formula (1) and formula (2):

[0059] (3);

[0060] When it is determined that the weight of the strip-pack product 400 is lower than the lowest set value of the preset weight range for three consecutive times, the filling mechanism 200 is controlled to increase the above-mentioned H value to increase the filling volume; when it is determined that the weight of the strip-pack product 400 is higher than the lowest set value of the preset weight range for three consecutive times, the filling mechanism 200 is controlled to decrease the above-mentioned H value to reduce the filling volume. The change in the H value can preferably be set to 0.1 mm.

[0061] See also Figure 5In one possible embodiment, the sorting conveyor 300 further includes a docking platform 320, a rejection station 330 and a drive assembly. The docking platform 320 is docked with the end of the docking slide 500 away from the strip bag output port; the rejection station 330 is arranged on the side of the checkweigher station 310 away from the docking platform 320, and there is a gap between the docking platform 320 and the rejection station 330 and the checkweigher station 310; the drive assembly includes a transmission chain 340 arranged along the moving direction of the strip bag product 400, and a shifting rod 350 connected to the transmission chain 340. The shifting rod 350 is used to push the strip bag product 400 on the docking platform 320 into the checkweigher station 310 for weighing under the drive of the transmission chain 340, and move it to the rejection station 330 after being weighed by the checkweigher station 310. The docking slide 500 includes several first slides for conveying individual stick-pack products 400. The docking platform 320 includes several second slides 321 for conveying individual stick-pack products 400. The checkweigher station 310 is provided with several third slides 311 for conveying and weighing individual stick-pack products 400. A checkweigher 312 is provided at the bottom of each third slide 311. The first slides correspond one-to-one with the second slides 321, and the second slides 321 correspond one-to-one with the third slides 311. The extension direction of the lever 350 is parallel to the arrangement direction of the third slides 311.

[0062] The bar-packaged product 400 is pushed to slide from right to left on the docking platform 320 by the lever 350. After the bar-packaged product 400 is transported to the checkweigher 312 platform, the value of the checkweigher 312 is read after a preset delay of 350ms. The value is processed by the PLC control system and stored in the industrial computer data storage system of the host computer software to realize the storage of weighing data. After weighing, the lever 350 immediately pushes the bar-packaged product 400 to slide to the rejection station 330, and then the unqualified bar-packaged product 400 is rejected. In order to prevent the equipment shaking from affecting the accuracy of the checkweigher 312, there is a gap between the docking platform 320 and the rejection station 330 and the checkweigher station 310, that is, the checkweigher 312 platform is installed independently and separated from the frame of the sorting conveyor 300.

[0063] In one possible embodiment, the first slide is an arc-shaped structure, the top of the arc-shaped structure is connected to the single outlet of the strip bag output port, and the bottom of the arc-shaped structure is connected to the second slide 321. The first slide is used to adjust the angle between the length direction of the strip bag product 400 and the extension direction of the second slide 321. By setting the first slide to an arc-shaped structure, the upright strip bag product 400 is converted into a sideways conveyor in the first slide, which can facilitate the smooth transfer of the strip bag product 400 from the strip bag output port of the strip bag packaging machine 100 to the second slide 321.

[0064] Furthermore, the docking platform 320 also includes a conveyor belt movably connected to the second slide 321 and corresponding one-to-one with the second slide 321, and a power device for driving all conveyor belts to move synchronously. The conveyor belt is used to drive the strip-packaged product 400 transported to the second slide 321 via the first slide toward the third slide 311. The second slide 321 and the third slide 311 are arranged horizontally, and the second slide 321 and the third slide 311 are at the same height, so as to facilitate the transfer of the strip-packaged product 400 from the second slide 321 to the third slide 311.

[0065] It can be understood that the bar-packed product 400 enters the first slide, changes from an upright shape to a side-standing shape, and then enters the horizontally arranged second slide 321 and is transported toward the third slide 311. The transmission chain 340 drives the lever 350 to move, driving the bar-packed product 400 to move from the second slide 321 into the third slide 311 with a checkweigher 312 at the bottom. The lever 350 is intermittently stepped to complete the checkweigher 312 on the bar-packed product 400 during the intermittent time. After stopping, the weighing data is read, and the stabilization time is 350ms. The weighing value is read 400ms after stopping. The PLC control system automatically compares and determines whether the weighing value is qualified. After weighing, the lever 350 is used to slide the bar-packed product 400 to the fourth slide 331 corresponding to the rejection station 330. Unqualified bar-packed products 400 are rejected, and qualified bar-packed products 400 continue to be transported backward. Qualified bar-packed products 400 are transported out of the product outlet 360 through the fourth slide 331.

[0066] Based on the above content, the present application also provides a multi-column strip bag production method with filling and weighing functions, which is suitable for a multi-column strip bag production system with filling and weighing functions. The multi-column strip bag production method with filling and weighing functions includes: obtaining the weight of the strip bag product 400 formed after being filled by the filling mechanism 200 and sealed by the strip bag packaging machine 100; adjusting the filling amount of the filling mechanism 200 when it is determined that the weight of the strip bag product 400 does not meet the preset weight range.

[0067] In one possible embodiment, the steps of adjusting the filling amount of the filling mechanism 200 when it is determined that the weight of the stick-packed product 400 does not meet the preset weight range are specifically as follows: when it is determined that the weight of the stick-packed product 400 is lower than the minimum set value of the preset weight range for three consecutive times, the filling mechanism 200 is controlled to increase the filling amount; when it is determined that the weight of the stick-packed product 400 is higher than the minimum set value of the preset weight range for three consecutive times, the filling mechanism 200 is controlled to reduce the filling amount.

[0068] The filling volume can be increased or decreased by adjusting the height of the drug in the plunger pump cavity 220 in the axial direction of the plunger pump cavity 220 when the plunger rod 260 moves relative to the plunger pump cavity 220 to complete drug extraction.

[0069] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0070] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0071] The principles and implementation methods of the present invention are described herein using specific examples. The description of the above examples is only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
