Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of powder-liquid dual-chamber bag production, and particularly relates to an automatic auxiliary agent feeding device. BACKGROUND

[0002] The powder-liquid dual-chamber bag product is a ready-to-use infusion product, and the bag body is composed of a transparent co-extrusion film. The product comprises a liquid chamber containing a solvent for injection and a powder chamber containing a drug powder, and the two chambers are separated by a weak welding separation strip. When used, medical staff only need 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 the powder-liquid dual-chamber bag production is usually polyethylene or polypropylene, which has a 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 dual-chamber bag is usually adopted to increase the barrier property of the packaging, so as to reduce the influence of moisture, oxygen and light on the sterile powder medicine and prevent the degradation of the powder medicine caused by moisture, oxygen and light.

[0004] The welding of the aluminum-plastic composite barrier film and the powder-liquid dual-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 dual-chamber bag, and then the aluminum film welding machine is used for heat sealing and welding to wrap the aluminum-plastic composite barrier film on the outer wall of the powder chamber, including the weak welding strip between the powder chamber and the liquid chamber and the film on the entire outer peripheral surface of the powder chamber.

[0005] There are many varieties of powder-liquid dual-chamber bags in the prior art, and different characteristics of the powder-liquid dual-chamber bags have different requirements for the equipment and the auxiliary agent to be fed. For example, the powder-liquid dual-chamber bag product with the 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 the aluminum-plastic composite barrier film on the outside of the powder chamber according to the process requirements. However, the powder-liquid dual-chamber bag product with special properties has special requirements for the equipment and the auxiliary agent to be fed, that is, when the aluminum-plastic composite barrier film is welded on the outside of the powder chamber, a desiccant and / or an oxygen absorber need to 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.

[0006] In the prior art, in order to meet the different feeding requirements of different products for the oxygen absorber and the desiccant, a manual feeding mode is adopted. The specific operation process is as follows: first, the large-circle oxygen absorber raw material is cut into single-piece oxygen absorbers, and after the cutting is completed, the single-piece oxygen absorbers are re-packed and vacuumized for standby; at the same time, adhesive tape and a large package of desiccant are prepared for standby. After the staff member is on duty, the vacuumized oxygen absorber and the large package of desiccant are unpacked, and the single-piece oxygen absorbers and the small package of desiccant are manually pasted in the middle part of the powder chamber by using the torn adhesive tape, and then sent to the aluminum film machine for aluminum film coating operation.

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

[0036] The following is a clear and complete description of the technical solutions in the embodiments of the present invention 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", "up", "down", "inside", "outside", "bottom", etc. used in this specification to indicate the orientation or position relationship are based on the orientation or position relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting this application.

[0037] 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.

[0038] 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.

[0039] The rack 9 provides support and an 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 dispensing machine 4 are all installed on the upper table 91.

[0040] The desiccant delivery system 1 is used to provide the entire device with available small packages of desiccant. The desiccant delivery system 1 includes a desiccant buffer 11, a desiccant vibration plate 12 and a desiccant material handling track 13.

[0041] Specifically, the large package of desiccant is opened and put into the desiccant buffer bin 11 . The desiccant buffer bin 11 stores the small packages of desiccant and feeds the desiccant vibration disk 12 .

[0042] The desiccant vibrating tray 12 is a device known in the prior art. It is connected to the desiccant buffer 11 and is equipped with a photoelectric switch. When the desiccant in the vibrating tray 12 is insufficient, the vibrating tray 12 vibrates, causing the desiccant in the desiccant buffer 11 to slide into the vibrating tray 12. The vibrating tray 12 extends to the top of the desiccant sorting track 13 via a slide rail, allowing the desiccant in the vibrating tray 12 to fall onto the desiccant sorting track 13 via the slide rail.

[0043] The desiccant material handling track 13 is a conveyor belt structure. A plurality of desiccant positioning grooves 131 are evenly distributed at equal intervals on the desiccant material handling track 13 along its own conveying direction.

[0044] Desiccant positioning groove 131 is a block-shaped structure protruding from the surface of desiccant handling track 13. Its upper surface is open and vertically recessed downward to form a positioning groove for placing and positioning the desiccant. Desiccant in desiccant vibrating plate 12 slides directly into desiccant positioning groove 131 and is then transported along desiccant handling track 13 to the retrieving mechanism 3.

[0045] The oxygen absorbent delivery system 2 is used to provide available small pieces of oxygen absorbent for the entire device. The oxygen absorbent delivery system 2 includes an oxygen absorbent delivery machine 21 and an oxygen absorbent material handling track 22.

[0046] The oxygen absorber bag 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 bag machine 21, the oxygen absorber bag 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 bag machine 21 is located directly above the oxygen absorber material sorting track 22.

[0047] The oxygen absorber material handling track 22 is a conveyor belt structure. A plurality of oxygen absorber positioning grooves 221 uniformly distributed at equal intervals are provided on the oxygen absorber material handling track 22 along its own conveying direction.

[0048] 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. Its upper surface is open and vertically recessed downward to form a positioning groove for placing and limiting the oxygen absorber.

[0049] The sheared 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 conveyed to the material taking mechanism 3 along the oxygen absorber material sorting track 22 .

[0050] 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.

[0051] The oxygen absorbent delivery system 2, the retrieving mechanism 3, and the desiccant delivery system 1 are sequentially arranged along the length of the upper table 91, with the desiccant delivery system 1 and the oxygen absorbent delivery system 2 located at either end of the retrieving mechanism 3. The desiccant handling track 13 and the oxygen absorbent handling track 22 are close to each other but do not touch each other, and are both located on the same side of the retrieving mechanism 3.

[0052] The picking mechanism 3 can grab the desiccant on the desiccant material handling track 13 or the oxygen absorbent on the oxygen absorbent material handling track 22. Specifically, the picking mechanism 3 is provided with two or more first suction cups 31 arranged vertically downward. In this embodiment, the picking mechanism 3 is provided with four first suction cups 31 whose arrangement direction is consistent with the conveying direction of the oxygen absorbent material handling track 22. 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. Therefore, the picking mechanism 3 can pick up four desiccants from the desiccant material handling track 13 at one time or four oxygen absorbers from the oxygen absorbent material handling track 22 at one time, thereby doubling the delivery efficiency.

[0053] 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.

[0054] The dispensing machine 4 is a device in the prior art. The dispensing machine 4 used in the present invention has two dispensing heads, namely an oxygen absorbent dispensing head 41 and an aluminum film dispensing head 42 .

[0055] 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 bag machine 21 and the material taking mechanism 3, and close to the discharge port of the oxygen absorber bag machine 21. The oxygen absorber dispensing head 41 is vertically downwardly aligned 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.

[0056] The unfolded aluminum film body 5 is located in the middle layer 92 of the frame 9. 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. The aluminum film dispensing head 42 dispenses glue vertically downward toward the upper surface of the aluminum film body 5.

[0057] After the retrieving mechanism 3 draws four desiccants from the desiccant feeding track 13, it places the four desiccants directly above the corresponding four oxygen absorbers. As the oxygen absorber's upper surface is glued by the oxygen absorber dispensing head 41, the oxygen absorber and the desiccant are bonded together to form an integrated additive group. A slot 911 is provided at the retrieving mechanism 3 on the upper table 91. After drawing the four additive groups, the retrieving mechanism 3 vertically passes through slot 911 to enter the intermediate layer 92. The retrieving mechanism 3 places the four adsorbed additive groups on the aluminum film body 5 at the four glue-dispensed points, thereby achieving adhesion and fixation of the additive groups to the aluminum film body 5 and realizing automatic dispensing.

[0058] An aluminum film slitting mechanism 6 , a visual inspection system 7 and a transfer mechanism 8 are also provided in the middle layer 92 .

[0059] The aluminum film slitting mechanism 6 and the visual inspection system 7 are both existing technologies. They are set at the same workstation. The aluminum film slitting mechanism 6 is used to cut the aluminum film body 5 with the additive group bonded thereto. The cut aluminum film body 5 can enter the next process.

[0060] 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 is provided for detecting whether the auxiliary agent group is bonded to the aluminum film body 5 .

[0061] 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 to the vacuum pipeline, and the distance between two adjacent second suction cups 81 is equal to the distance between the two first suction cups 31.

[0062] If the visual inspection system 7 identifies a certain aluminum film body 5 as unqualified, that is, the aluminum film body 5 is not successfully bonded with the auxiliary agent group, the transfer mechanism 8 will operate to remove the aluminum film body 5 that is not bonded with the auxiliary agent group; if the visual inspection system 7 identifies a certain aluminum film body 5 as qualified, that is, the aluminum film body 5 is successfully bonded with the auxiliary agent group, the transfer mechanism 8 will operate to transport the aluminum film body 5 bonded with the auxiliary agent group to the next workstation for aluminum film coating operation.

[0063] In particular, the oxygen absorber dispensing head 41, desiccant delivery system 1, and oxygen absorber delivery system 2 in this device can all be selectively turned on or off. Auxiliary agents are divided into separate desiccant, separate oxygen absorber, and an auxiliary agent group formed by combining oxygen absorber and desiccant. For batches of different types of powder-liquid dual-chamber bag products, the requirements for auxiliary agents vary. Therefore, the desiccant delivery system 1 or the oxygen absorber delivery system 2, or both, can be selectively turned on, thereby achieving rapid switching of the type of auxiliary agent to be delivered. The specific process is as follows:

[0064] When a powder-liquid dual-chamber bag product requires the simultaneous addition of an oxygen absorber and a desiccant, the desiccant dispensing system 1 and the oxygen absorber dispensing system 2 are activated simultaneously, and both the oxygen absorber dispensing head 41 and the aluminum film dispensing head 42 of the dispensing machine 4 are in operation. A 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 feeding track 22. As the oxygen absorber passes through the oxygen absorber dispensing head 41 under the transport of the oxygen absorber feeding track 22, the upper surface of the oxygen absorber is dispensed with glue. The dispensed oxygen absorber is then conveyed to the feeding mechanism 3; at the same time, the desiccant feeding track 13 also conveys the desiccant to the feeding mechanism 3. At this point, the cylinder of the feeding mechanism 3 is activated, and the feeding mechanism 3 moves to the top of the desiccant. After the first suction cup 31 absorbs the desiccant, the feeding mechanism 3 moves the desiccant to the top of the oxygen absorber. The desiccant and oxygen absorbent are in contact and bonded together to form an additive group. After the material picking mechanism 3 adsorbs the additive group, the cylinder is actuated, causing the material picking mechanism 3 to vertically downwardly pass 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 passes through the aluminum film dispensing head 42 and is glued at intervals. The material picking mechanism 3 places the four adsorbed additive groups on the aluminum film body 5 at the four glue-dispensing points to complete the bonding and fixation of the aluminum film body 5 and the additive groups. The aluminum film slitting mechanism 6 cuts the aluminum film body 5 that arrives at its workstation. The visual inspection system 7 detects whether the additive group is successfully bonded to the aluminum film body 5. Finally, the transfer mechanism 8 removes unqualified aluminum film bodies 5 and transports qualified aluminum film bodies 5 to the next workstation for aluminum film coating.

[0065] When a powder-liquid dual-chamber bag product only requires the addition of oxygen absorbent, the oxygen absorbent dispensing system 2 is activated while the desiccant dispensing system 1 is deactivated. Furthermore, the oxygen absorbent dispensing head 41 of the dispensing machine 4 is deactivated while the aluminum film dispensing head 42 is activated. A single piece of oxygen absorbent falls from the discharge port of the oxygen absorbent bag dispenser 21 into the oxygen absorbent positioning slot 221 on the oxygen absorbent material handling track 22 and is directly transferred to the retrieving mechanism 3. At this point, the pneumatic cylinder of the retrieving mechanism 3 is actuated, moving the retrieving mechanism 3 above the oxygen absorbent. After the first suction cup 31 absorbs the oxygen absorbent, the pneumatic cylinder of the retrieving mechanism 3 is actuated, allowing the retrieving mechanism 3 to vertically downwardly pass through the elongated hole 911 in the upper table 91 and reach above the aluminum film body 5. After passing through the aluminum film dispensing head 42, the upper surface of the aluminum film body 5 is glued at intervals. The retrieving mechanism 3 places the four absorbed oxygen absorbents on the aluminum film body 5 at the four glued points, completing the bonding and fixing of the aluminum film body 5 to the oxygen absorbent. 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.

[0066] When a powder-liquid dual-chamber bag product only requires desiccant delivery, the desiccant delivery system 1 is activated while the oxygen absorber delivery system 2 is deactivated. Furthermore, the oxygen absorber dispensing head 41 of the dispensing machine 4 is deactivated while the aluminum film dispensing head 42 is activated. After the desiccant handling track 13 delivers the desiccant to the retrieving mechanism 3, the pneumatic cylinder of the retrieving mechanism 3 is actuated, moving the retrieving mechanism 3 over the desiccant. After the first suction cup 31 absorbs the desiccant, the pneumatic cylinder of the retrieving mechanism 3 is actuated, allowing the retrieving mechanism 3 to vertically downwardly pass through the elongated hole 911 on the upper table 91 and reach over 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. The retrieving mechanism 3 places the four adsorbed desiccants on the aluminum film body 5 at the four glue-dispensed points, completing the bonding and fixing of the aluminum film body 5 to 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 adhered 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.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the invention.
