Description

TECHNICAL FIELD

[0001] The utility model relates to powder-liquid double-chamber bag production technical field especially relates to a kind of automatic feeding equipment of oxygen absorbent and desiccant. BACKGROUND

[0002] Powder-liquid double-chamber bag product is a ready-to-use infusion product, and the bag body is composed of transparent co-extrusion film. The product includes a liquid chamber containing solvent for injection and a powder chamber containing drug powder, and the two chambers are separated by a weak welding separation strip. When in use, medical staff only needs to gently squeeze the liquid chamber to open the weak welding separation strip between the two chambers, so that the solvent for injection in the liquid chamber and the drug powder in the powder chamber are fully mixed for use.

[0003] The film material used for powder-liquid double-chamber bag production is usually polyethylene or polypropylene, which has certain permeability to oxygen and water vapor in the air and cannot avoid light. Therefore, the method of welding aluminum-plastic composite barrier film on both upper and lower surfaces of the powder chamber of the powder-liquid double-chamber bag is usually used to increase the barrier property of the packaging, thereby reducing the influence of moisture, oxygen and light on sterile powder drugs and preventing the degradation of powder drugs due to moisture, oxygen and light.

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

[0005] There are many varieties of powder-liquid double-chamber bags in the prior art, and different characteristics of powder-liquid double-chamber bags have different requirements for equipment and the aid to be put in. For example, the powder-liquid double-chamber bag product with aluminum-plastic composite barrier film welded on the outside of the powder chamber does not have specific requirements for the equipment, and only needs to complete the welding of aluminum-plastic composite barrier film on the outside of the powder chamber according to the process requirements. However, the powder-liquid double-chamber bag product with special properties has special requirements for the equipment and the aid to be put in, i.e. when welding aluminum-plastic composite barrier film on the outside of the powder chamber, desiccant and / or oxygen absorbent should be placed between the powder chamber and the aluminum-plastic composite barrier film on the outside to ensure that only a small amount of air remains between the powder chamber, the two sides of the powder chamber and the aluminum-plastic composite barrier film.

The specific operation process is as follows: first, the oxygen absorber raw material is cut into a single piece of oxygen absorber, and after cutting, the single piece of oxygen absorber is repackaged and vacuumized for standby; meanwhile, adhesive tape and a large bag of desiccant are prepared for standby. After the staff member is on duty, the vacuumized oxygen absorber and the large bag of desiccant are unpacked, and the single piece of oxygen absorber and the small bag of desiccant are manually adhered to the middle part of the powder cavity by using the adhesive tape torn into sections, and then sent to an aluminum film machine for aluminum film coating operation.

In order to facilitate the description, the terms "vertical", "horizontal", "left", "right", "up", "down", "inner", "outer", "bottom" and the like used in the specification indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0036] Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative labor belong to the scope of protection of the present application.

[0037] As shown in the drawings, Figs. 1-3 An auxiliary agent automatic putting equipment includes a rack 9, a drying agent putting system 1, an oxygen absorbent putting system 2, a material taking mechanism 3 and a dispensing machine 4.

[0038] The rack 9 provides support and mounting platform for other system structures on the device, the rack 9 includes an upper table 91 and an intermediate layer 92 below the upper table 91, the desiccant feeding system 1, the oxygen absorber feeding system 2 and the dispenser 4 are all mounted on the upper table 91.

[0039] The desiccant feeding system 1 is used to provide available small packages of desiccant for the whole device. The desiccant feeding system 1 includes a desiccant buffer bin 11, a desiccant vibrating disc 12 and a desiccant material sorting track 13.

[0040] Specifically, the large package of desiccant is opened and put into the desiccant buffer bin 11, the desiccant buffer bin 11 stores small packages of desiccant and supplies the desiccant vibrating disc 12.

[0041] The desiccant vibrating disc 12 is a device in the prior art, which is connected with the desiccant buffer bin 11, and a photoelectric switch is installed on the desiccant vibrating disc 12, when the amount of desiccant in the desiccant vibrating disc 12 is insufficient, the desiccant vibrating disc 12 makes the desiccant in the desiccant buffer bin 11 slide into the desiccant vibrating disc 12 by vibration. The desiccant vibrating disc 12 extends to above the desiccant material sorting track 13 through a slide rail, so that the desiccant in the desiccant vibrating disc 12 falls to the desiccant material sorting track 13 through the slide rail.

[0042] The desiccant material sorting track 13 is a conveyor belt structure, and a plurality of desiccant positioning grooves 131 are uniformly distributed at equal intervals along the conveying direction of the desiccant material sorting track 13.

[0043] The desiccant positioning groove 131 is a block structure protruding from the surface of the desiccant material sorting track 13, the upper surface of which is open and vertically downwardly recessed to form a positioning groove for placing and limiting the desiccant. The desiccant in the desiccant vibrating disc 12 directly slides into the desiccant positioning groove 131 and is conveyed to the material taking mechanism 3 along with the desiccant material sorting track 13.

[0044] The oxygen absorber feeding system 2 is used to provide available small blocks of oxygen absorber for the whole device. The oxygen absorber feeding system 2 includes an oxygen absorber feeding machine 21 and an oxygen absorber material sorting track 22.

[0045] The oxygen absorber feeding machine 21 is a device in the prior art that can cut oxygen absorber, after a large circle of oxygen absorber is put into the oxygen absorber feeding machine 21, the oxygen absorber feeding machine 21 starts to cut the large circle of oxygen absorber into single pieces of fixed size and shape, and the discharge port of the oxygen absorber feeding machine 21 is located directly above the oxygen absorber material sorting track 22.

[0046] The oxygen absorber material sorting track 22 is a conveyor belt structure, and a plurality of oxygen absorber positioning grooves 221 are uniformly distributed at equal intervals along the conveying direction of the oxygen absorber material sorting track 22.

[0047] 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 track 22, and the upper surface is open and vertically downwardly recessed to form a positioning groove for placing and limiting the oxygen absorber.

[0048] The sheared oxygen absorber directly falls into the oxygen absorber positioning groove 221 through the discharge port of the oxygen absorber feeding machine 21, and is then conveyed to the material taking mechanism 3 along with the oxygen absorber material track 22.

[0049] In particular, the distance between any two adjacent desiccant positioning grooves 131 is equal to the distance between any two adjacent oxygen absorber positioning grooves 221, and the conveying directions of the desiccant material track 13 and the oxygen absorber material track 22 are parallel to each other.

[0050] The oxygen absorber feeding system 2, the material taking mechanism 3, and the desiccant feeding system 1 are sequentially arranged along the length direction of the upper table 91, that is, the desiccant feeding system 1 and the oxygen absorber feeding system 2 are respectively located at the two ends of the material taking mechanism 3. The desiccant material track 13 and the oxygen absorber material 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.

[0051] The material taking mechanism 3 can grasp the desiccant on the desiccant material track 13 or the oxygen absorber on the oxygen absorber material track 22. Specifically, the material taking mechanism 3 is provided with two or more first suction cups 31 arranged vertically downward. In this embodiment, the material taking mechanism 3 is provided with four first suction cups 31 arranged in the same direction as the conveying direction of the oxygen absorber material track 22. The four first suction cups 31 are arranged at equal intervals, and the distance between any two adjacent first suction cups 31 is equal to the distance between any two adjacent desiccant positioning grooves 131. Therefore, the material taking mechanism 3 can grasp four desiccants on the desiccant material track 13 at a time or grasp four oxygen absorbers on the oxygen absorber material track 22 at a time, thereby doubling the feeding efficiency.

[0052] The material taking mechanism 3 is driven by a pneumatic cylinder in the horizontal direction and the vertical direction, and the first suction cup 31 is connected with a vacuum pipeline. The on-off control of the vacuum pipeline can control the suction and release of the oxygen absorber or the desiccant by the first suction cup 31, and the spatial position of the material taking mechanism 3 can be controlled by controlling the extension and retraction of the pneumatic cylinder.

[0053] The dispensing machine 4 is a device in the prior art. The dispensing machine 4 used in the present application has two dispensing heads, namely an oxygen absorber dispensing head 41 and an aluminum film dispensing head 42.

[0054] The oxygen absorber dispensing head 41 is arranged on the upper surface 91, and is located between the oxygen absorber dispensing machine 21 and the material taking mechanism 3, and is close to the discharge port of the oxygen absorber dispensing machine 21. The oxygen absorber dispensing head 41 is vertically downwardly aligned with the oxygen absorber positioning groove 221 on the oxygen absorber sorting track 22. When the oxygen absorber sorting track 22 is running, the oxygen absorber dispensing head 41 dispenses glue on the upper surface of each oxygen absorber located in the oxygen absorber positioning groove 221.

[0055] The expanded aluminum film body 5 is located in the middle layer 92 of the rack 9, and the length direction of the aluminum film body 5 is consistent with the length direction of the rack 9. The aluminum film dispensing head 42 is also arranged in the middle layer 92, and is vertically downwardly spaced from the upper surface of the aluminum film body 5.

[0056] After the material taking mechanism 3 takes four desiccants from the desiccant sorting track 13, the four desiccants are placed directly above the corresponding four oxygen absorbers. Since the upper surface of the oxygen absorber is dispensed by the oxygen absorber dispensing head 41, the oxygen absorber and the desiccant are bonded to form an integrated aid group. A long hole 911 is formed on the material taking mechanism 3 of the upper surface 91. After taking four aid groups, the material taking mechanism 3 vertically passes through the long hole 911 to enter the middle layer 92. The material taking mechanism 3 places the four aid groups adsorbed on the four points of the aluminum film body 5, thereby realizing the bonding and fixing of the aid group and the aluminum film body 5, and realizing automatic dispensing.

[0057] The middle layer 92 further comprises an aluminum film slitting mechanism 6, a visual detection system 7 and a transfer mechanism 8.

[0058] The aluminum film slitting mechanism 6 and the visual detection system 7 are both prior art, and are arranged at the same station. The aluminum film slitting mechanism 6 is used to cut the aluminum film body 5 bonded with the aid group. The cut aluminum film body 5 can enter the next station.

[0059] In order to prevent the aluminum film body 5 without successfully bonded aid group from flowing into the next station, the visual detection system 7 is arranged to detect whether the aluminum film body 5 is bonded with the aid group.

[0060] The transfer mechanism 8 acts according to the detection result of the visual detection system 7. Specifically, the transfer mechanism 8 also comprises four second suction cups 81 connected with vacuum pipes, and the distance between two adjacent second suction cups 81 is equal to the distance between the two first suction cups 31.

[0061] If the visual detection system 7 identifies the aluminum film body 5 as unqualified, i.e. the aluminum film body 5 has not successfully bonded the aid group, the transfer mechanism 8 is actuated to remove the aluminum film body 5 without the aid group; if the visual detection system 7 identifies the aluminum film body 5 as qualified, i.e. the aluminum film body 5 has successfully bonded the aid group, the transfer mechanism 8 is actuated to carry the aluminum film body 5 with the aid group to the next station for aluminum film coating operation.

[0062] In particular, the oxygen absorber dispensing head 41, the desiccant dispensing system 1 and the oxygen absorber dispensing system 2 in the present device can be selectively opened or closed. The aids are divided into separate desiccants, separate oxygen absorbers and aid groups formed by the combination of oxygen absorbers and desiccants. Different types of powder-liquid dual-chamber bag products in batches have different requirements for aids, so the desiccant dispensing system 1 or the oxygen absorber dispensing system 2 can be selectively opened alone, or both can be opened, thereby realizing rapid switching of the type of aid to be dispensed. The specific process is as follows:

[0063] When the powder-liquid dual-chamber bag product needs to simultaneously dispense oxygen absorbers and desiccants, the desiccant dispensing system 1 and the oxygen absorber dispensing system 2 are simultaneously started, and the oxygen absorber dispensing head 41 and the aluminum film dispensing head 42 of the dispensing machine 4 are both working. The single oxygen absorber falls from the discharge port of the oxygen absorber dispensing machine 21 into the oxygen absorber positioning groove 221 on the oxygen absorber sorting track 22, and the upper surface of the oxygen absorber is dispensed when the oxygen absorber passes through the oxygen absorber dispensing head 41 under the conveying of the oxygen absorber sorting track 22. The dispensed oxygen absorber is continuously conveyed to the taking mechanism 3; at the same time, the desiccant sorting track 13 also conveys the desiccant to the taking mechanism 3. At this time, the cylinder of the taking mechanism 3 is actuated, the taking mechanism 3 moves to above the desiccant, and after the first suction cup 31 adsorbs the desiccant, the taking mechanism 3 carries the desiccant to move directly above the oxygen absorber. The aid group formed by the contact and bonding of the desiccant and the oxygen absorber is adsorbed by the taking mechanism 3, and the cylinder is actuated to make the taking mechanism 3 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 interval-dispensed after passing through the aluminum film dispensing head 42, and the taking mechanism 3 places the four adsorbed aid groups on the aluminum film body 5 on the four points dispensed by the dispensing head to complete the bonding and fixation of the aluminum film body 5 and the aid group. The aluminum film cutting mechanism 6 cuts the aluminum film body 5 that reaches its station, the visual detection system 7 detects whether the aluminum film body 5 has successfully bonded the aid group, and finally the transfer mechanism 8 removes the unqualified aluminum film body 5 and carries the qualified aluminum film body 5 to the next station for aluminum film coating operation.

[0064] When the powder-liquid dual-chamber bag product only needs to put in the oxygen absorber, the oxygen absorber putting system 2 starts to work and the dry agent putting system 1 does not start, and the oxygen absorber dispensing head 41 of the dispensing machine 4 does not work and the aluminum film dispensing head 42 works. The single oxygen absorber falls from the discharge port of the oxygen absorber putting machine 21 into the oxygen absorber positioning groove 221 on the oxygen absorber material track 22 and is directly conveyed to the material taking mechanism 3. At this time, the cylinder of the material taking mechanism 3 acts, the material taking mechanism 3 moves to above the oxygen absorber, after the first suction cup 31 adsorbs the oxygen absorber, the cylinder of the material taking mechanism 3 acts so that the material taking mechanism 3 vertically downwardly passes 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 interval-dispensed after passing through the aluminum film dispensing head 42, the material taking mechanism 3 places the four adsorbed oxygen absorbers on the four points of the aluminum film body 5 which are dispensed to complete the bonding and fixing of the aluminum film body 5 and the oxygen absorber. The aluminum film cutting mechanism 6 cuts the aluminum film body 5 which reaches its working position, the visual detection system 7 detects whether the aluminum film body 5 successfully bonds the oxygen absorber, and finally the transfer mechanism 8 rejects the unqualified aluminum film body 5 and carries the qualified aluminum film body 5 to the next working position for aluminum film coating operation.

[0065] When the powder-liquid dual-chamber bag product only needs to put in the oxygen absorber, the oxygen absorber putting system 2 starts to work and the dry agent putting system 1 does not start, and the oxygen absorber dispensing head 41 of the dispensing machine 4 does not work and the aluminum film dispensing head 42 works. The single oxygen absorber falls from the discharge port of the oxygen absorber putting machine 21 into the oxygen absorber positioning groove 221 on the oxygen absorber material track 22 and is directly conveyed to the material taking mechanism 3. At this time, the cylinder of the material taking mechanism 3 acts, the material taking mechanism 3 moves to above the oxygen absorber, after the first suction cup 31 adsorbs the oxygen absorber, the cylinder of the material taking mechanism 3 acts so that the material taking mechanism 3 vertically downwardly passes 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 interval-dispensed after passing through the aluminum film dispensing head 42, the material taking mechanism 3 places the four adsorbed oxygen absorbers on the four points of the aluminum film body 5 which are dispensed to complete the bonding and fixing of the aluminum film body 5 and the oxygen absorber. The aluminum film cutting mechanism 6 cuts the aluminum film body 5 which reaches its working position, the visual detection system 7 detects whether the aluminum film body 5 successfully bonds the oxygen absorber, and finally the transfer mechanism 8 rejects the unqualified aluminum film body 5 and carries the qualified aluminum film body 5 to the next working position for aluminum film coating operation.
