Description

Technical Field

[0001] The invention relates to the technical field of powder-liquid double-chamber bag production, in particular to an automatic auxiliary agent delivery device. Background Art

[0002] The powder-liquid dual-chamber bag product is a ready-to-mix infusion product. The bag body is made of a transparent co-extruded film. The product consists of a liquid chamber containing an injection solvent and a powder chamber containing drug powder. The two chambers are separated by a weakly welded separator. When in use, medical staff only need to gently squeeze the liquid chamber to open the weakly welded separator between the two chambers, so that the injection solvent in the liquid chamber and the drug powder in the powder chamber are fully mixed for use.

[0003] The film material used in making powder-liquid double-chamber bags is usually polyethylene or polypropylene, which has a certain permeability to oxygen, water vapor, etc. in the air and cannot avoid light. Therefore, it is usually adopted to weld aluminum-plastic composite barrier film on both the upper and lower sides of the powder chamber of the powder-liquid double-chamber bag to increase the barrier property of the packaging, thereby reducing the impact of moisture, oxygen and light on sterile powder drugs, and preventing the degradation of powder drugs due to moisture, oxygen, light, etc.

[0004] The welding of the aluminum-plastic composite barrier film and the powder-liquid double-chamber bag is completed by an aluminum film welding machine. First, the aluminum-plastic composite barrier film is set on both sides of the powder cavity of the powder-liquid double-chamber bag, and then the aluminum-plastic composite barrier film is wrapped around the outer wall of the powder cavity by heat welding using the aluminum film welding machine, including the weak welding rod at the transition between the powder cavity and the liquid cavity, and the entire outer peripheral surface film of the powder cavity.

[0005] There are many varieties of powder-liquid double-chamber bags in the prior art, and powder-liquid double-chamber bags with different characteristics have different requirements on equipment and additives. For example, some powder-liquid double-chamber bag products have no specific requirements on equipment for welding the aluminum-plastic composite barrier film on the outside of the powder chamber, and it is only necessary to complete the welding of the aluminum-plastic composite barrier film on the outside of the powder chamber according to the process requirements; while powder-liquid double-chamber bag products with special properties have special requirements on equipment and additives, that is, when welding the aluminum-plastic composite barrier film on the outside of the powder chamber, a desiccant and / or an oxygen absorber must be placed between the powder chamber and the outer aluminum-plastic composite barrier film to ensure that only a very small amount of air remains in the powder chamber, between the two sides of the powder chamber and the aluminum-plastic composite barrier film.

[0006] In the prior art, in order to meet the different delivery requirements of oxygen absorbers and desiccants for different products, a manual delivery mode is adopted. The specific operation process is: first cut the large circle of oxygen absorber raw materials into single pieces of oxygen absorbers, and after cutting, re-pack the single pieces of oxygen absorbers and vacuumize them for standby use; at the same time, prepare tape and large packages of desiccant for standby use. After the staff takes up their posts, they disassemble the vacuumed oxygen absorbers and large packages of desiccant, and manually use the torn tape to stick the single pieces of oxygen absorbers and small packages of desiccant in the middle of the powder chamber, and then send them to the aluminum film machine for aluminum film coating.

[0007] The manual pasting of oxygen absorbers and desiccants has a series of disadvantages that increase production costs, such as low work efficiency, unstable pasting quality, and high labor intensity. In order to match the running speed of the aluminum film welding machine, effectively reduce labor intensity, further improve product yield and ensure output stability, it is necessary to develop an automatic delivery device for oxygen absorbers and desiccants.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0024] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0025] As attached Figure 1-3 As shown, an automatic additive delivery device includes a frame 9, a desiccant delivery system 1, an oxygen absorbent delivery system 2, a material taking mechanism 3 and a glue dispenser 4.

[0026] The rack 9 provides support and installation platform for other system structures on the equipment. The rack 9 includes an upper table 91 and an intermediate layer 92 located below the upper table 91 . The desiccant delivery system 1 , the oxygen absorbent delivery system 2 and the glue dispenser 4 are all installed on the upper table 91 .

[0027] The desiccant delivery system 1 is used to provide available small packages of desiccant for the entire device. The desiccant delivery system 1 comprises a desiccant buffer 11 , a desiccant vibration plate 12 and a desiccant material handling track 13 .

[0028] Specifically, the large package of desiccant is opened and put into the desiccant buffer bin 11 , and the desiccant buffer bin 11 stores the small packages of desiccant and supplies the desiccant vibration disk 12 .

[0029] The desiccant vibration plate 12 is a device in the prior art, which is connected to the desiccant buffer bin 11, and a photoelectric switch is installed on the desiccant vibration plate 12. When the amount of desiccant in the desiccant vibration plate 12 is insufficient, the desiccant vibration plate 12 vibrates to make the desiccant in the desiccant buffer bin 11 slide into the desiccant vibration plate 12. The desiccant vibration plate 12 extends to the top of the desiccant material handling track 13 through a slide rail, so that the desiccant in the desiccant vibration plate 12 falls to the desiccant material handling track 13 through the slide rail.

[0030] The desiccant material handling track 13 is a conveyor belt structure, and a plurality of desiccant positioning grooves 131 evenly distributed at equal intervals are arranged on the desiccant material handling track 13 along its own conveying direction.

[0031] The desiccant positioning groove 131 is a block-shaped structure protruding from the surface of the desiccant material handling track 13, with an opening on the upper surface and a vertical depression downward to form a positioning groove for placing and limiting the desiccant. The desiccant in the desiccant vibration plate 12 directly slides into the desiccant positioning groove 131 and is then transferred to the material taking mechanism 3 along the desiccant material handling track 13.

[0032] The oxygen absorbent delivery system 2 is used to provide available small pieces of oxygen absorbent for the whole equipment. The oxygen absorbent delivery system 2 comprises an oxygen absorbent delivery machine 21 and an oxygen absorbent material handling track 22.

[0033] The oxygen absorber package machine 21 is a device in the prior art that can cut oxygen absorbers. After a large circle of oxygen absorber is placed into the oxygen absorber package machine 21, the oxygen absorber package machine 21 is started to cut the large circle of oxygen absorber into single pieces of oxygen absorber with fixed size and shape. The discharge port of the oxygen absorber package machine 21 is located directly above the oxygen absorber material sorting track 22.

[0034] The oxygen absorber material handling track 22 is a conveyor belt structure, and a plurality of oxygen absorber positioning grooves 221 evenly distributed at equal intervals are arranged on the oxygen absorber material handling track 22 along its own conveying direction.

[0035] The oxygen absorber positioning groove 221 is similar to the desiccant positioning groove 131. The oxygen absorber positioning groove 221 is a block structure protruding from the surface of the oxygen absorber material handling track 22. Its upper surface is open and vertically recessed downward to form a positioning groove for placing and limiting the oxygen absorber.

[0036] The cut and formed oxygen absorber directly falls into the oxygen absorber positioning groove 221 through the discharge port of the oxygen absorber bagging machine 21 and is then transferred to the material taking mechanism 3 along the oxygen absorber material sorting track 22 .

[0037] In particular, the distance between any two adjacent desiccant positioning grooves 131 is equal to the distance between any two adjacent oxygen absorbent positioning grooves 221 , and the conveying directions of the desiccant material handling track 13 and the oxygen absorbent material handling track 22 are parallel to each other.

[0038] The oxygen absorbent delivery system 2, the material taking mechanism 3 and the desiccant delivery system 1 are sequentially distributed along the length direction of the upper table 91, that is, the desiccant delivery system 1 and the oxygen absorbent delivery system 2 are respectively located at the two ends of the material taking mechanism 3. The desiccant material handling track 13 and the oxygen absorbent material handling track 22 are close to each other but not in contact, and both are located on the same side of the material taking mechanism 3.

[0039] The material picking mechanism 3 can grab the desiccant on the desiccant material handling track 13 or the oxygen absorber on the oxygen absorber material handling track 22. Specifically, the material picking mechanism 3 is provided with more than two first suction cups 31 arranged vertically downward. In the present embodiment, the material picking mechanism 3 is provided with four first suction cups 31 arranged in the same direction as the conveying direction of the oxygen absorber material handling track 22, and the four first suction cups 31 are arranged at equal intervals and the distance between two adjacent first suction cups 31 is equal to the distance between two adjacent desiccant positioning grooves 131. Thus, the material picking mechanism 3 can suck four desiccants from the desiccant material handling track 13 at one time or suck four oxygen absorbers from the oxygen absorber material handling track 22 at one time, thereby doubling the delivery efficiency.

[0040] The material picking mechanism 3 is driven by cylinders in the horizontal and vertical directions, and the first suction cup 31 is connected to a vacuum pipeline. By controlling the on and off of the vacuum pipeline, the first suction cup 31 can be controlled to absorb and release the oxygen absorber or desiccant. The spatial position of the material picking mechanism 3 can be controlled by controlling the extension and contraction of the cylinder.

[0041] The glue dispensing machine 4 is a device in the prior art. The glue dispensing machine 4 used in the present invention has two glue dispensing heads, namely an oxygen absorbent glue dispensing head 41 and an aluminum film glue dispensing head 42 .

[0042] The oxygen absorber dispensing head 41 is set on the upper table 91. The oxygen absorber dispensing head 41 is located between the oxygen absorber package machine 21 and the material taking mechanism 3, and close to the discharge port of the oxygen absorber package machine 21. The oxygen absorber dispensing head 41 is vertically aligned downward with the oxygen absorber positioning groove 221 on the oxygen absorber material sorting track 22. When the oxygen absorber material sorting track 22 is running, the oxygen absorber dispensing head 41 dispenses glue to the upper surface of each oxygen absorber located in the oxygen absorber positioning groove 221.

[0043] The unfolded aluminum film body 5 is located in the middle layer 92 of the frame 9 , and the length direction of the aluminum film body 5 is consistent with the length direction of the frame 9 . The aluminum film dispensing head 42 is also arranged in the middle layer 92 , and the aluminum film dispensing head 42 dispenses glue vertically downward toward the upper surface of the aluminum film body 5 .

[0044] After the material taking mechanism 3 absorbs four desiccants from the desiccant material handling track 13, the four desiccants are placed directly above the corresponding four oxygen absorbers. Since the upper surface of the oxygen absorber is glued by the oxygen absorber glue head 41, the oxygen absorber and the desiccant are bonded to form an integrated auxiliary agent group. A long hole 911 is provided at the material taking mechanism 3 on the upper table 91. After the material taking mechanism 3 absorbs the four auxiliary agent groups, it can vertically pass through the long hole 911 to enter the middle layer 92. The material taking mechanism 3 places the four adsorbed auxiliary agent groups on the four points on the aluminum film body 5 where glue is dispensed, thereby achieving the bonding and fixation of the auxiliary agent group and the aluminum film body 5, and realizing automatic delivery.

[0045] An aluminum film slitting mechanism 6 , a visual inspection system 7 and a transfer mechanism 8 are also provided in the middle layer 92 .

[0046] The aluminum film slitting mechanism 6 and the visual inspection system 7 are both existing technologies, and are arranged at the same workstation. The aluminum film slitting mechanism 6 is used to cut the aluminum film body 5 with the adhesive additive group, and the cut aluminum film body 5 can enter the next process.

[0047] In order to prevent the aluminum film body 5 that is not successfully bonded with the auxiliary agent group from flowing into the next process, a visual inspection system 7 for detecting whether the auxiliary agent group is bonded to the aluminum film body 5 is provided.

[0048] The transfer mechanism 8 operates according to the detection result of the visual detection system 7. Specifically, the transfer mechanism 8 is also provided with four second suction cups 81 connected with vacuum pipelines, and the distance between two adjacent second suction cups 81 is equal to the distance between two first suction cups 31.

[0049] If the visual inspection system 7 recognizes that a certain aluminum film body 5 is unqualified, that is, the aluminum film body 5 is not successfully bonded to the auxiliary agent group, the transfer mechanism 8 will be activated to remove the aluminum film body 5 that is not bonded to the auxiliary agent group; if the visual inspection system 7 recognizes that a certain aluminum film body 5 is qualified, that is, the aluminum film body 5 is successfully bonded to the auxiliary agent group, the transfer mechanism 8 will be activated to transport the aluminum film body 5 bonded with the auxiliary agent group to the next workstation for aluminum film coating operation.

[0050] In particular, the oxygen absorber dispensing head 41, the desiccant delivery system 1 and the oxygen absorber delivery system 2 in the device can be selectively turned on or off. The additives are divided into a single desiccant, a single oxygen absorber and an additive group formed by a combination of an oxygen absorber and a desiccant. For batches of different types of powder-liquid double-chamber bag products, the requirements for additives are different. Therefore, the desiccant delivery system 1 or the oxygen absorber delivery system 2 can be selectively turned on separately, or both can be turned on, so as to achieve rapid switching of the type of additives delivered. The specific process is as follows: When the powder-liquid double-chamber bag product needs to be put into oxygen absorber and desiccant at the same time, the desiccant putting system 1 and the oxygen absorber putting system 2 start working at the same time, and the oxygen absorber dispensing head 41 and the aluminum film dispensing head 42 of the dispensing machine 4 are both working. The single piece of oxygen absorber falls from the discharge port of the oxygen absorber bagging machine 21 into the oxygen absorber positioning groove 221 on the oxygen absorber material handling track 22. When the oxygen absorber passes through the oxygen absorber dispensing head 41 under the transmission of the oxygen absorber material handling track 22, the upper surface of the oxygen absorber is dispensed with glue, and the dispensed oxygen absorber is further conveyed to the material taking mechanism 3; at the same time, the desiccant material handling track 13 also conveys the desiccant to the material taking mechanism 3. At this time, the cylinder of the material taking mechanism 3 is actuated, and the material taking mechanism 3 moves to the top of the desiccant. After the first suction cup 31 absorbs the desiccant, the material taking mechanism 3 moves the desiccant to the top of the oxygen absorber. The desiccant and the oxygen absorbent are in contact and bonded to form an auxiliary agent group. After the material taking mechanism 3 adsorbs the auxiliary agent group, the cylinder moves so that the material taking mechanism 3 passes vertically downward through the long hole 911 on the upper table 91 to reach the top of the aluminum film body 5. The upper surface of the aluminum film body 5 is glued at intervals after passing through the aluminum film glue dispensing head 42. The material taking mechanism 3 places the four adsorbed auxiliary agent groups on the aluminum film body 5 at the four points of glue dispensing to complete the bonding and fixing of the aluminum film body 5 and the auxiliary agent group. The aluminum film cutting mechanism 6 cuts the aluminum film body 5 that arrives at its station, and the visual inspection system 7 detects whether the auxiliary agent group is successfully bonded to the aluminum film body 5. Finally, the transfer mechanism 8 is used to remove the unqualified aluminum film body 5 and move the qualified aluminum film body 5 to the next station for aluminum film coating.

[0051] When the powder-liquid double-chamber bag product only needs to be put in the oxygen absorber, the oxygen absorber putting system 2 starts working while the desiccant putting system 1 does not start, and the oxygen absorber putting head 41 of the glue dispenser 4 does not work while the aluminum film putting head 42 works. The single piece of oxygen absorber falls from the discharge port of the oxygen absorber bag dispenser 21 into the oxygen absorber positioning groove 221 on the oxygen absorber material handling track 22, and is directly transferred to the material taking mechanism 3. At this time, the cylinder of the material taking mechanism 3 is actuated, and the material taking mechanism 3 moves above the oxygen absorber. After the first suction cup 31 absorbs the oxygen absorber, the cylinder of the material taking mechanism 3 is actuated so that the material taking mechanism 3 passes vertically downward through the long hole 911 on the upper table 91 to reach above the aluminum film body 5. The upper surface of the aluminum film body 5 is glued at intervals after passing through the aluminum film glue dispensing head 42. The material taking mechanism 3 places the four oxygen absorbers adsorbed on the aluminum film body 5 at the four points of glue dispensing to complete the bonding and fixing of the aluminum film body 5 and the oxygen absorber. The aluminum film slitting mechanism 6 cuts the aluminum film body 5 that arrives at its workstation, and the visual inspection system 7 detects whether the oxygen absorber is successfully bonded to the aluminum film body 5. Finally, the transfer mechanism 8 is used to remove unqualified aluminum film bodies 5 and transport qualified aluminum film bodies 5 to the next workstation for aluminum film coating operations.

[0052] When the powder-liquid double-chamber bag product only needs to be put in desiccant, the desiccant putting system 1 starts working while the oxygen absorbent putting system 2 does not start, and the oxygen absorbent dispensing head 41 of the dispensing machine 4 does not work while the aluminum film dispensing head 42 works. After the desiccant material track 13 transfers the desiccant to the material taking mechanism 3, the cylinder of the material taking mechanism 3 is actuated, and the material taking mechanism 3 moves to the top of the desiccant. After the first suction cup 31 absorbs the desiccant, the cylinder of the material taking mechanism 3 is actuated so that the material taking mechanism 3 passes vertically downward through the long hole 911 on the upper table 91 to the top of the aluminum film body 5. The upper surface of the aluminum film body 5 is glued at intervals after passing through the aluminum film dispensing head 42, and the material taking mechanism 3 places the four adsorbed desiccants on the aluminum film body 5 at the four points where glue is dispensed to complete the bonding and fixing of the aluminum film body 5 and the desiccant. The aluminum film slitting mechanism 6 cuts the aluminum film body 5 that arrives at its workstation, and the visual inspection system 7 detects whether the desiccant is successfully bonded to the aluminum film body 5. Finally, the transfer mechanism 8 is used to remove unqualified aluminum film bodies 5 and transport qualified aluminum film bodies 5 to the next workstation for aluminum film coating operations.
