Description

Technical Field

[0001] The invention relates to the technical field of infusion bag transmission and feeding, in particular to an infusion bag feeding device supporting multiple lines. Background Art

[0002] Currently in the medical industry, infusion bags are the most commonly used medical products. In the production process of infusion bags, the feeding device is a system used to transport liquid medicine, solvents, etc. to the filling equipment. It plays a key role in the production of infusion bags. The feeding device ensures that the raw materials can be accurately delivered to the filling equipment, thereby ensuring the accurate volume and composition of the liquid in each infusion bag. The feeding device is designed with a sterile system to prevent the raw materials from being contaminated during the transportation process, accurately control the feeding speed and amount, ensure the continuity and efficiency of the production process, reduce the errors and contamination risks caused by human operation, avoid the waste of raw materials, and improve production efficiency and cost-effectiveness.

[0003] The existing Chinese patent with authorization announcement number CN205668794U discloses a multi-channel feeding conveyor line for infusion bags, including a shunt device for shunting a single-channel infusion bag into multiple branches and a conveyor line for separately conveying each infusion bag branch shunted by the shunt device. The number of the conveyor lines is equal to the number of branches shunted by the shunt device. One channel of infusion bags is shunted into multiple channels for simultaneous feeding, which greatly improves production efficiency. The shunt structure used is sophisticated, and the lateral translation of the sliding block and the horizontal bar is used to achieve material separation. The material separation is accurate and will not damage the infusion bag. The transmission fixture on the conveyor line can be replaced or the size of the storage space can be adjusted by the baffle, which improves the adaptability of the entire feeding conveyor line.

[0004] However, since the above technical solution cannot adjust the angle when transmitting the infusion bag, there is a deviation in the angle of the infusion bag after diversion, which reduces the subsequent processing efficiency.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention. This embodiment provides an infusion bag loading device that supports multiple lines, including a conveying mechanism, a sorting mechanism and a labeling mechanism. The processor controls the transmission motor 1009 and the air pump to realize the sorting of the infusion bags 102 and the switching of the conveying lines. It can switch freely from many to one or from one to many to cope with different working scenes. While conveying, the balance frame 200 is used to perform quality comparison, detect and compare product quality, and sort, and automatically remove unqualified infusion bags 102.

[0037] Specifically, it includes a conveying mechanism, including a reversing disc 100, a conveyor belt 101 arranged in a circumferential array on the periphery of the reversing disc 100, and an infusion bag 102 arranged on the conveyor belt 101, and the reversing disc 100 is used to move the infusion bag 102 from the current conveyor belt 101 to the adjacent conveyor belt 101;

[0038] The sorting mechanism includes a balance frame 200 and a suction cup 201 disposed in the reversing disk 100. The suction cup 201 is fixedly attached to the infusion bag 102 when under negative pressure. The balance frame 200 is used to compare the weight of the infusion bag 102.

[0039] The labeling mechanism includes a positioning cover 300 and a roller 301 rotatably arranged inside the positioning cover 300. An array of suction cups 201 are arranged on the lower end surface of the positioning cover 300. A label is wound on the surface of the roller 301. After the suction cup 201 is fixed to the infusion bag 102, the roller 301 rolls along the surface of the infusion bag 102.

[0040] Among them, in this embodiment, the conveyor belt 101 has a total of 4 lines, and is distributed in a circular array at an interval of 90°. The shape of the positioning cover 300 is consistent with the shape of the infusion bag 102. In this embodiment, the number of suction cups 201 can be 1 and is rotatably arranged on the lower end surface of the positioning cover 300. The infusion bag 102 can rotate with the suction cup 201 to achieve angle adjustment, so that the infusion bag 102 can be embedded in the positioning cover 300 to play an auxiliary positioning function.

[0041] Exemplarily, in this embodiment, the label adopts adhesive label paper, and the label paper is set with an easy-tear line according to the set specifications and dimensions. The label paper is wound on the surface of the roller 301 and the side in contact with the infusion bag 102 is sticky. When the roller 301 approaches the infusion bag 102, a section of the label paper extending from the roller 301 contacts the infusion bag 102 and adheres to its surface. Then the roller 301 rolls in contact with the infusion bag 102 and prints the label paper on the surface of the infusion bag 102. When the label paper reaches the edge of the infusion bag 102, the roller 301 no longer contacts the infusion bag 102 and thus stops rolling. At this time, the easy-tear line of the label paper also just rolls to the edge of the infusion bag 102. As the roller 301 continues to move forward, the label paper breaks from the easy-tear line. Then the roller 301 resets and the above actions are continued until the label paper roll is used up and a new label paper roll is replaced.

[0042] Preferably, the number of suction cups 201 can also be four, which are movably arranged at the four corners of the positioning cover 300 respectively. The suction cups 201 are made of soft rubber material and can slide freely on the surface of the infusion bag 102 without ventilation. When negative pressure is applied to the suction cups 201, the suction cups 201 are fixed to the surface of the infusion bag 102, and the suction cups 201 are compressed under the drive of the negative pressure, and the infusion bag 102 is embedded in the positioning cover 300, so that the offset infusion bag 102 can be automatically corrected.

[0043] Preferably, the balancing frame 200 includes a turntable 1001 , and a first turn slot 1002 and a second turn slot 1003 are respectively formed on the turntable 1001 , and the first turn slot 1002 and the second turn slot 1003 are arranged perpendicular to each other.

[0044] The first rotating groove 1002 and the second rotating groove 1003 are respectively provided with a first balancing rod 1004 and a second balancing rod 1005 for rotation, and the first balancing rod 1004 and the second balancing rod 1005 rotate around their respective midpoints at the same time.

[0045] More preferably, two first rotation grooves 1002 and two second rotation grooves 1003 are symmetrically provided, two first balance poles 1004 and two second balance poles 1005 are respectively provided and are respectively arranged in parallel, and the rotation amplitude between the two parallel first balance poles 1004 and the two second balance poles 1005 is always the same.

[0046] Among them, a first connecting rod 1006 is rotatably provided between each first balancing rod 1004, and the first connecting rod 1006 is used to ensure that the rotation range of each first balancing rod 1004 is always the same. A second connecting rod 1007 is rotatably provided between each second balancing rod 1005, and the second connecting rod 1007 is used to ensure that the rotation range of each second balancing rod 1005 is always the same.

[0047] The first connecting rod 1006 , the second connecting rod 1007 , the first balancing rod 1004 , and the second balancing rod 1005 are all rectangular straight rods, which are rotatably connected via rotating shafts. The turntable 1001 is a vertically placed rectangular block, and the center point coincides with the center of the reversing disc 100 .

[0048] Furthermore, a transmission shaft 1008 is provided on the upper end surface of the turntable 1001 , and a transmission motor 1009 is provided at one end of the transmission shaft 1008 . The transmission shaft 1008 rotates through the reversing disc 100 and is connected to the center of the turntable 1001 .

[0049] Among them, in this embodiment, each conveyor belt 101 is named in clockwise order from the left: the first line, the second line, the third line, and the fourth line, the transmission motor 1009 is a servo motor, and the air passages of the suction cup 201 on the same positioning cover 300 are connected at the same time and are uniformly controlled by the air pump. The present invention also includes a processor, and the processor is equipped with a control unit for controlling the rotation angle of the transmission motor 1009 and the air pump switch, and the transmission motor 1009 and the air pump are uniformly controlled by the processor.

[0050] Preferably, the first balance bar 1004 and the second balance bar 1005 form a lever. When the weight of the infusion bags 102 on both sides is the same, it proves that the injection volume is the same, which meets the sorting requirements. At this time, the labeling operation can be performed. When the weight of the infusion bag 102 leaks and is too little, the lever loses balance, does not meet the sorting requirements, and no labeling is performed.

[0051] In summary, during use, when the infusion bags 102 on the first line need to be sorted into a plurality of branch lines, the processor controls the transmission motor 1009 and the transmission shaft 1008 to rotate, the positioning cover 300 moves to the top of the infusion bag 102, and at the same time, the suction cup 201 under the positioning cover 300 slides to the surface of the infusion bag 102, and then the processor starts the air pump to inhale, and negative pressure is generated in the suction cup 201, and the suction cup 201 is fixed to the surface of the infusion bag 102, and the suction cup 201 is compressed under the negative pressure, and the infusion bag 102 is embedded in the positioning cover 300, so that the offset infusion bag 102 is automatically corrected, and then the processor controls the transmission motor 1009 to rotate 90 degrees clockwise. °, so that the positioning cover 300 moves to the second line, and then the air pump is closed, the negative pressure disappears, and the infusion bag 102 falls onto the conveyor belt 101 on the second line. In this state, the positioning cover 300 on the first line generates negative pressure and adsorbs the next infusion bag 102. Finally, the transmission motor 1009 rotates 90° counterclockwise to reset, and transports the infusion bag 102 to the fourth line, realizing the sorting and line switching of the infusion bag 102, and realizing the switching of the conveying line from one to many, thereby improving the processing efficiency of the subsequent process. Similarly, by adopting the opposite steps, the line switching from many to one can be realized, so as to flexibly cope with the different processing procedures of the infusion bag 102.

[0052] At the same time, when the infusion bag 102 is reversed to the upper feed, there are four positioning covers 300. Two adjacent positioning covers 300 are used to absorb and fix the infusion bag 102. The two positioning covers 300 symmetrically arranged therewith are fixed with infusion bags 102 of standard weight. Whenever the suction cup 201 absorbs a new infusion bag 102, the weight is compared through the balance frame 200. The first balance bar 1004 and the second balance bar 1005 on the balance frame 200 form a lever. When the weights of the infusion bags 102 on both sides are the same, it proves that the injection amounts are the same, which meets the sorting requirements. At this time, the labeling operation can be performed. When the weight of the infusion bag 102 leaks and is too little, the lever loses balance and does not meet the sorting requirements. At this time, the air pump controlled by the processor automatically shuts down when the transmission motor 1009 rotates 45°, causing unqualified products to fall automatically and not enter the subsequent conveyor belt 101, and no labeling is performed. The sorting function is realized while transmission is in progress, and products that do not meet the quality requirements are selected.

[0053] Example 2

[0054] Reference Figure 1 to Figure 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that while sorting and switching lines of the infusion bags 102, labeling operations can also be performed on the infusion bags 102 that meet the quality requirements, which are integrated in the same step, reducing space and maintenance costs and improving efficiency.

[0055] Specifically, a slot 3001 is provided on the lower end surface of the positioning cover 300 , a guide post 3002 is rotatably provided in the slot 3001 , a cavity 3003 is further provided in the slot 3001 , and a movable post 3004 is rotatably sleeved on one end of the guide post 3002 .

[0056] Preferably, the movable column 3004 is threadedly rotated to penetrate the slot 3001 , and an impeller 3005 is provided at one end of the movable column 3004 extending into the cavity 3003 , and the impeller 3005 follows the movable column 3004 to slide in the cavity 3003 .

[0057] Among them, the card slot 3001 has the same shape as the infusion bag 102, so that the infusion bag 102 can be inserted into the card slot 3001. In other embodiments, for a cylindrical infusion bottle, the suction cup 201 can be replaced and adjusted to a shape that fits therewith, and the card slot 3001 can be adjusted to an elliptical slot, so that it can also be compatible with a cylindrical infusion bottle, increasing the usage scenarios.

[0058] The movable column 3004 and the guide column 3002 are sleeved by a bearing, so that when the movable column 3004 and the slot 3001 rotate and move through the thread, only the guide column 3002 will be driven to move without rotating.

[0059] Preferably, the cavity 3003 is connected to each suction cup 201. When the air pump is started, the suction cup 201 inhales air and discharges the gas to the air pump through the cavity 3003. During the inhalation process, the gas drives the impeller 3005 to rotate counterclockwise. Since the movable column 3004 is threadedly connected to the slot 3001 and is fully lubricated, the movable column 3004 rotates and moves outward, driving the guide column 3002 to move.

[0060] Furthermore, a support 3006 is provided at one end of the guide column 3002 close to the movable column 3004, and the roller 301 is rotatably provided on the support 3006. The outer wall of the movable column 3004 is sleeved with a first elastic member 3014, and both ends of the first elastic member 3014 are respectively connected to the support 3006 and the inner wall of the slot 3001.

[0061] Among them, the support 3006 is a rotating seat set vertically on the guide column 3002, and the roller 301 rolls back and forth along the direction of the guide column 3002. A label is wrapped on the surface of the roller 301, and the sticky side faces outward. When the roller 301 can adhere to the surface of the infusion bag 102 and roll, the label is adhered to the surface.

[0062] Preferably, the first elastic member 3014 is a spring. When the impeller 3005 rotates to drive the movable column 3004 and the guide column 3002 to move outward, the first elastic member 3014 is compressed. When the suction cup 201 and the infusion bag 102 are fixed, the airflow disappears, and under the push of the first elastic member 3014, the impeller 3005 and the guide column 3002 move inward and reset.

[0063] In summary, during use, when the positioning cover 300 moves to the top of the infusion bag 102 and the air pump is controlled by the processor, the suction cup 201 starts to inhale air, an airflow is generated in the cavity 3003, and the impeller 3005 is blown to rotate. At the same time, the moving column 3004 rotates and moves outward to the farthest point along the card slot 3001 threadedly engaged with it, and the first elastic member 3014 is compressed, eventually driving the infusion bag 102 to move upward and fit into the card slot 3001. When the suction cup 201 is completely attached to and sealed with the surface of the infusion bag 102, the balance bar is used to determine whether the current quality of the infusion bag 102 meets the requirements.

[0064] At the same time, when the infusion bag 102 is qualified, no gas flows into the suction cup 201 anymore, and the airflow in the cavity 3003 disappears at this time, the impeller 3005 stops rotating, and the first elastic member 3014 drives the guide column 3002 to reset and move inward, and at the same time drives the movable column 3004 to rotate in the opposite direction and reset. In other embodiments, the impeller 3005 has a deflection angle, and can further discharge the airflow in the cavity 3003 during reverse rotation, thereby improving the sealing and adsorption effect. While the guide column 3002 moves in the opposite direction, the infusion bag 102 is upwardly embedded in the card slot 3001 and adheres to the surface of the roller 301. A label is wound on the surface of the roller 301, and the sticky side faces outward. When the roller 301 can roll in contact with the surface of the infusion bag 102, the label is adhered to the surface to realize the labeling function.

[0065] Example 3

[0066] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, and the difference is that when an unqualified infusion bag 102 is detected, the limiting rod 3008 drives the limiting sleeve 3009 to lock the guide column 3002, thereby preventing the unqualified products from being labeled, thereby realizing automatic detection of the quality of the infusion bag 102.

[0067] Specifically, a sorting opening 3007 is opened at the upper end of the positioning cover 300, and a limiting rod 3008 is movably provided in the sorting opening 3007. A limiting sleeve 3009 is rotatably provided at one end of the limiting rod 3008 located in the slot 3001.

[0068] Among them, a support rod 3013 is rotatably provided at the midpoint of the limiting shell 3009, and the support rod 3013 is fixedly provided on the inner wall of the slot 3001. A serrated groove 3011 is provided on the outer wall of the guide column 3002 close to one end of the limiting shell 3009, and a serration 3012 is provided on the inner wall of the limiting shell 3009.

[0069] Preferably, the limiting sleeve 3009 is arranged in parallel with the guide column 3002 , and one end of the limiting rod 3008 away from the positioning cover 300 is rotatably connected to the first balance rod 1004 and the second balance rod 1005 respectively.

[0070] Furthermore, when the weight of the infusion bag 102 sucked up by the suction cup 201 is qualified, the first balance bar 1004 and the second balance bar 1005 remain horizontal, and the angle of the limiting rod 3008 changes, driving the limiting shell 3009 to move, so that the limiting shell 3009 is parallel to the guide column 3002.

[0071] Preferably, when the first balance bar 1004 and the second balance bar 1005 rotate due to the lever losing balance, the limiting housing 3009 tilts, and the saw teeth 3012 engage with the sawtooth groove 3011, and the two are locked so that the guide column 3002 cannot move.

[0072] Among them, when the infusion bag 102 is damaged and leaks, the levers formed by the first balance bar 1004 and the second balance bar 1005 lose balance and rotate upward around the midpoint, so that the limiting rod 3008 drives the limiting sleeve 3009 to rotate around the support rod 3013, and makes the saw teeth 3012 engage with the sawtooth groove 3011, preventing the guide column 3002 from continuing to move, stopping the labeling, and marking the defective products.

[0073] In summary, when in use, the suction cup 201 contacts and adsorbs and fits the new infusion bag 102. When the quality of the infusion bag 102 does not meet the requirements, the levers formed by the first balance bar 1004 and the second balance bar 1005 lose balance and rotate upward around the midpoint. The limiting rod 3008 also drives the limiting shell 3009 to rotate around the support rod 3013, tilting and deviating from the initial equilibrium position. The limiting shell 3009 tilts so that the saw teeth 3012 engage with the sawtooth groove 3011. The two are locked so that the guide column 3002 cannot move, preventing the guide column 3002 from continuing to move, and the roller 301 cannot move, so that the product is not labeled, and is marked as an unqualified product, thereby realizing automatic quality detection and sorting.

[0074] Importantly, it should be noted that the construction and arrangement of the present application shown in a number of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, changes in orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application.
