Technical Field

[0001] This utility model relates to the field of multi-row strip bag production technology, and in particular to a multi-row strip bag production system with filling and weighing functions. Background Technology

[0002] Multi-row strip bag packaging machine production lines mainly consist of a film welding system and a filling mechanism to package products. The required filling volume is achieved by setting the parameters of the filling mechanism. In the pharmaceutical and food industries, the requirements for filling accuracy are becoming increasingly stringent. Generally, the filling accuracy requirement is to ensure that the filling volume deviation is within 1%. Multi-row strip bag packaging machines have a large number of rows, and the requirements for filling accuracy are strict. Each row is equipped with an independent filling mechanism. Due to the error of the mechanical mechanism, the control system parameters will have slight differences. During continuous production, the filling volume will fluctuate due to various factors, affecting the filling accuracy.

[0003] Therefore, how to effectively improve the filling accuracy of strip packaging products is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] In the description of this utility model, it should be understood that the terms "upper", "lower", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0043] The purpose of this invention is to provide a multi-row strip bag production system with filling and weighing functions, which can effectively improve the filling accuracy of strip bag products.

[0044] Please see Figures 1 to 5To achieve the above objectives, this utility model provides a multi-row strip bag production system with filling and weighing functions, including a strip bag packaging machine 100, a filling mechanism 200, and a sorting conveyor 300. The strip bag packaging machine 100 is provided with a filling station and a strip bag output port. The strip bag packaging machine 100 is used to seal the filled strip bags to form strip 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 strip bags located at the filling station. The sorting conveyor 300 is connected to the strip bag output port through a docking slide 500. The docking slide 500 is used to transfer the strip package products 400 from the strip bag output port to the sorting conveyor 300. The sorting conveyor 300 is provided with a checkweigher station 310. The checkweigher station 310 is used to weigh the strip bags after they have been conveyed by the docking slide 500.

[0045] By integrating a strip bag packaging machine 100 with a filling station, a filling mechanism 200 for drug filling, and a sorting conveyor 300 with a checkweigher station 310 and connected to 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 strip bags can be directly weighed at 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, effectively improving the filling accuracy of the strip bag products 400.

[0046] In one possible implementation, the filling mechanism 200 includes a storage tank, a plunger pump chamber 220, an inlet 230, an outlet 240, a rotary valve mechanism 250, and a plunger rod 260. The storage tank is used to store the drug, which is liquid. The plunger pump chamber 220 has a receiving space. The cross-sectional shape of the receiving space can be, but is not limited to, circular, and the size of the circular cross-section can be set according to actual needs. The inlet 230 communicates with the receiving space; the outlet 240 communicates with the receiving space. The rotary valve mechanism 250 is used to close the inlet 230 when the outlet 240 and the filling channel 210 are connected. The rotary valve mechanism 250 is also used to close the outlet 240 when the inlet 230 and the outlet of the storage tank are connected. The plunger rod 260 is movably connected to the plunger pump chamber 220 to draw the preset filling amount of drug when the outlet 240 is closed, and to deliver the preset filling amount of drug to the filling channel 210 for drug filling when the inlet 230 is closed.

[0047] The plunger pump chamber 220, inlet 230, outlet 240, plunger rod 260, and filling channel 210 are all corresponding to each other, so that the plunger rod 260 communicates with the independent inlet 230 when drawing liquid and with the independent outlet 240 when pushing liquid. The independent filling channel 210 allows the medicine in the plunger pump chamber 220 to be filled into a single strip bag. By setting multiple sets of plunger pump chambers 220, inlets 230, outlets 240, plunger rods 260, and filling channels 210, multiple strip bags can be filled with medicine simultaneously, improving production efficiency. The plunger rod 260 can be a ceramic plunger rod. Multiple outlets 240 can be connected to the same storage tank through independent delivery pipes. A storage tank can also be added as needed, so that the storage tank can be used to supply liquid to a single plunger pump chamber 220.

[0048] In one possible implementation, the multi-row 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 lead screw 280 that is driven to the output end of the power source 270, and a slider sleeved on the lead screw 280 and capable of moving along the extension direction of the lead screw 280. The slider is connected to the plunger rod 260. When the power source 270 drives the lead screw 280 to rotate, it can drive the slider and the plunger rod 260 to move relative to the plunger pump cavity 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 achieve the liquid-drawing and liquid-pushing actions of the plunger rod 260. The volume of the plunger pump chamber 220 controls the filling amount. That is, the power source 270 controls the two extreme positions of the plunger rod 260's reciprocating movement within the plunger pump chamber 220 to control the filling amount. In other words, the displacement parameters of the plunger rod 260 driven by the servo motor control the filling amount. These displacement parameters can include reference parameters and deviation parameters. After filling, the packaged products 400 enter the checkweigher station 310 on the sorting conveyor 300 for single-bag weighing. The real-time weighing value is compared with the highest and lowest set values. When three consecutive packages of products 400 show a low or high filling amount, the PLC control system automatically adjusts the corresponding servo motor deviation parameters. The highest and lowest weighing set values ​​are related to the density of the filled product and can be set according to customer requirements. Weighing values ​​are stored in an industrial computer data storage system. Data can be queried by filtering by production date, batch number, specifications, etc., enabling 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, effectively ensuring product quality.

[0049] It should be noted that the internal space of the plunger pump chamber 220 can be configured as a cylindrical structure. The plunger rod 260 moves back and forth 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 accommodating space of the plunger pump chamber 220 when the plunger rod 260 moves relative to the plunger pump chamber 220 to complete the drug extraction. This volume is related to the product of the circular cross-sectional area of ​​the accommodating space of the plunger pump chamber 220 and the height of the accommodating space perpendicular to the cross-sectional area. The cross-sectional area of ​​the accommodating space of the plunger pump chamber 220 is known data, and the height of the accommodating space perpendicular to the cross-sectional area is related to the stroke of the plunger rod 260.

[0050] (1); where M is the mass of the drug in the 400 strip products, ρ is the density of the drug in the 400 strip products, and V is the volume of the drug in the 400 strip products.

[0051] (2); where R is the cross-sectional radius of the plunger pump chamber 220, H is the height of the drug in the plunger pump chamber 220 along the axial direction of the plunger pump chamber 220 when the plunger rod 260 moves relative to the plunger pump chamber 220 to complete the drug extraction (the displacement parameter of the plunger rod 260), and V is the volume of the drug in the strip package product 400.

[0052] It can be derived from formulas (1) and (2) that...

[0053] (3); When it is determined that the weight of the strip product 400 is lower than the minimum set value of the preset weight range three times in a row, the filling mechanism 200 is controlled to increase the above-mentioned H value to increase the filling amount; when it is determined that the weight of the strip product 400 is higher than the minimum set value of the preset weight range three times in a row, the filling mechanism 200 is controlled to decrease the above-mentioned H value to reduce the filling amount. The change in H value can preferably be set to 0.1mm.

[0054] Please see Figure 5In one possible implementation, 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 opposite to the strip bag output port. The rejection station 330 is located on the side of the checkweigher station 310 opposite to 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 package product 400, and a lever 350 connected to the transmission chain 340. The lever 350 is used to push the strip package product 400 on the docking platform 320 into the checkweigher station 310 for weighing under the drive of the transmission chain 340, and after being weighed by the checkweigher station 310, it moves to the rejection station 330. The docking chute 500 includes several first chutes for conveying individual packaged products 400, the docking platform 320 includes several second chutes 321 for conveying individual packaged products 400, and the checkweigher station 310 is provided with several third chutes 311 for conveying and weighing individual packaged products 400. Each third chute 311 has a checkweigher 312 at its bottom. The first chute and the second chute 321 correspond one-to-one, and the second chute 321 and the third chute 311 correspond one-to-one. The extension direction of the lever 350 is parallel to the arrangement direction of the third chute 311.

[0055] The packaged product 400 slides from right to left on the docking platform 320 via a lever 350. After the packaged product 400 is conveyed 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 control computer data storage system of the host computer software to realize the storage of weighing data. After the weighing is completed, the lever 350 immediately moves the packaged product 400 to the rejection station 330, and then the unqualified packaged product 400 is rejected. In order to avoid the equipment shaking 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 is separate from the frame of the sorting conveyor 300.

[0056] In one possible implementation, the first slide is an arc-shaped structure, with the top of the arc-shaped structure connecting to a single outlet of the strip bag output port and the bottom of the arc-shaped structure connecting to the second slide 321. The first slide is used to adjust the angle between the length direction of the strip package product 400 and the extension direction of the second slide 321. By setting the first slide to an arc-shaped structure, the upright strip package product 400 is transported in a side-standing position in the first slide, which facilitates the smooth transfer of the strip package product 400 from the strip bag output port of the strip bag packaging machine 100 to the second slide 321.

[0057] Furthermore, the docking platform 320 also includes a conveyor belt that is movably connected to the second slide rail 321 and corresponds one-to-one with the second slide rail 321, and a power device for driving all the conveyor belts to move synchronously. The conveyor belt is used to drive the strip package product 400 that has been transported from the first slide rail to the second slide rail 321 to move toward the third slide rail 311. The second slide rail 321 and the third slide rail 311 are horizontally arranged and at the same height, which facilitates the transfer of the strip package product 400 from the second slide rail 321 to the third slide rail 311.

[0058] Understandably, the packaged product 400 enters the first slide rail, changing from an upright to a sideways position. It then enters the horizontally positioned second slide rail 321 and is conveyed towards the third slide rail 311. The transmission chain 340 drives the lever 350 to move, moving the packaged product 400 from the second slide rail 321 into the third slide rail 311, which has a checkweigher 312 at its bottom. The lever 350 moves intermittently, completing the transfer of the packaged product 400 onto the checkweigher 312 within the intervals. After the device comes to a complete stop, the weighing data is read. The stabilization time is 350ms. The weighing value is read again after 400ms of stabilization. The PLC control system automatically compares and determines whether the weighing value is qualified. After weighing, the strip package product 400 is slid to the fourth slide rail 331 corresponding to the rejection station 330 via lever 350. The unqualified strip package product 400 is rejected, and the qualified strip package product 400 continues to be conveyed. The qualified strip package product 400 is conveyed out of the product outlet 360 through the fourth slide rail 331.

[0059] Based on the above, this application also provides a method for producing multi-row strip bags with filling and weighing functions, applicable to multi-row strip bag production systems with filling and weighing functions. The method for producing multi-row strip bags 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; and 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.

[0060] In one possible implementation, the step of adjusting the filling amount of the filling mechanism 200 when it is determined that the weight of the strip product 400 does not meet the preset weight range specifically includes: when it is determined that the weight of the strip product 400 is lower than the minimum set value of the preset weight range three times in a row, the filling mechanism 200 is controlled to increase the filling amount; when it is determined that the weight of the strip product 400 is higher than the minimum set value of the preset weight range three times in a row, the filling mechanism 200 is controlled to decrease the filling amount.

[0061] The increase or decrease in filling volume can be achieved by adjusting the movement of the plunger rod 260 relative to the plunger pump chamber 220 to complete the height of the drug in the plunger pump chamber 220 along the axial direction of the plunger pump chamber 220 during drug extraction.

[0062] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0063] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0064] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
