Description

Technical Field

[0001] This utility model relates to the field of powder and liquid double-chamber bag production equipment, and in particular to an automatic bag-loading and bag-adding device for powder and liquid double-chamber bags. Background Technology

[0002] The powder-liquid dual-chamber bag is a ready-to-use infusion product. The bag body is made of a transparent co-extruded film. The product consists of two parts: a liquid chamber containing the injectable solvent and a powder chamber containing the drug powder. The two chambers are separated by a weakly welded partition. During use, medical personnel simply squeeze the liquid chamber to open the weakly welded partition, allowing the injectable solvent in the liquid chamber and the drug powder in the powder chamber to mix thoroughly before intravenous infusion.

[0003] In the existing production process, after the liquid raw material is filled into the liquid chamber of the powder-liquid dual-chamber bag product, the bag containing the liquid medicine needs to be sent to the powder filling machine to fill the powder medicine into the powder chamber. To minimize the contamination of the product caused by manual operation, an automatic bag-loading device for the powder filling machine is needed. This device would automatically load the bag containing the powder medicine onto the powder filling machine before the powder filling process, and then proceed with the powder medicine filling.

[0004] In existing technology, a sterilization loading fixture and a fixture conveyor track are used to feed the powder-liquid dual-chamber bags containing liquid medications into the powder filling machine. The specific process is as follows: After the powder-liquid dual-chamber bags containing liquid medications are sent into the sterilization chamber, they are loaded onto the sterilization loading fixture. The sterilization loading fixture then carries the powder-liquid dual-chamber bags along the fixture conveyor track to the powder filling station, where the bag loading mechanism loads the bags from the sterilization loading fixture onto the powder filling machine for powder medication filling. Then, the empty sterilization loading fixture returns to the sterilization chamber via another fixture circulation track, where new infusion bags are loaded and conveyed to the powder filling station.

[0005] In actual production, it was found that after the sterilization loading clamps were loaded with bags, the time it took for the empty clamps to return to the sterilization chamber via the clamp circulation track was too long, which slowed down the bag loading speed. Furthermore, a malfunction in either the clamp conveying track or the clamp circulation track would cause production to stop, affecting the production efficiency of the powder-liquid dual-chamber bags. Therefore, the existing technology still needs to be improved. Utility Model Content

[0006] To address the problems existing in the prior art, such as the excessive time it takes for empty sterilization loading clamps to return to the sterilization chamber via the clamp circulation track, and the high number of devices and failure rate in the entire process, which slows down production efficiency, this utility model aims to provide an automatic bag-loading and bag-dispensing device for powder and liquid dual-chamber bags. By redesigning the conveying process of the sterilization loading clamps and adjusting the clamp conveying track, the device structure is simplified, the speed of empty clamps returning to the sterilization chamber is accelerated, and production efficiency is improved.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] An automatic bag-loading and unloading device for powder and liquid dual-chamber bags includes a clamp conveying track and a sterilization loading clamp. The sterilization loading clamp is used to suspend and fix the infusion bag and convey the infusion bag along the clamp conveying track. It also includes a clamp fixing device and a bag-removing mechanism. The clamp fixing device is used to limit and fix the sterilization loading clamp. The bag-removing mechanism is provided with a bag-removing gripper. The bag-removing gripper is used to remove the infusion bag from the sterilization loading clamp in the clamp fixing device. After removing the infusion bag, the sterilization loading clamp returns to its initial position along the clamp conveying track.

[0009] The present invention is further configured such that: multiple sterilization loading clamps are simultaneously arranged on the clamp conveying track, all the sterilization loading clamps move synchronously, and the clamp fixing device simultaneously fixes all the sterilization loading clamps; the number of bag-taking grippers provided on the bag-taking mechanism is equal to the number of sterilization loading clamps that the clamp fixing device can simultaneously fix.

[0010] The present invention is further configured such that: the distance between any two adjacent sterilization loading clamps in the clamp fixing device is equal, and the distance between two adjacent sterilization loading clamps in the clamp fixing device is equal to the distance between two adjacent bag-taking clamps on the bag-taking mechanism.

[0011] The present invention is further configured to include a clamp positioning mechanism, which is located upstream of the clamp fixing device. The clamp positioning mechanism is used to drag all synchronously moving sterilization loading clamps to the clamp fixing device.

[0012] The present invention is further configured such that the clamp positioning mechanism can adjust the distance between the sterilization loading clamps.

[0013] The present invention is further configured such that: the fixture positioning mechanism includes a holding base, a positioning plate, a positioning detection element, and a power element; the length direction of the holding base is consistent with the conveying direction of the fixture conveying track; the positioning plate is mounted on the holding base and is retractable; each sterilization loading fixture has a positioning plate on each side in the conveying direction; the power element drives the positioning plate to move along the holding base; the positioning plate drives the sterilization loading fixture to move; and the positioning detection element is used to detect the position of the sterilization loading fixture.

[0014] The present invention is further configured such that: the clamp fixing device includes a fixing block and a frame, the fixing block is installed on the frame and can approach and press the sterilization loading clamp in a direction perpendicular to the clamp conveying direction of the clamp conveying track or move away from the clamp conveying track and release the sterilization loading clamp.

[0015] The present invention is further configured such that: the fixing block includes a first fixing block and a second fixing block, the length of the first fixing block is greater than that of the second fixing block, and the first fixing block and the second fixing block cooperate to press and fix or release the sterilization loading clamp.

[0016] In summary, the beneficial effects achieved by this utility model are as follows:

[0017] (1) By setting up a clamp fixing device and a bag taking mechanism, the sterilization loading clamp can be fixed at a specific position on the clamp conveying track without leaving the clamp conveying track. The bag taking mechanism then removes the infusion bag from the fixed sterilization loading clamp, thus enabling the sterilization loading clamp to complete the task of conveying the infusion bag. The empty sterilization loading clamp returns directly to the initial position of the sterilization loading clamp, i.e., the sterilization chamber, via the clamp conveying track. The infusion bag is then reloaded in the sterilization chamber. Thus, the bag delivery and return are achieved simultaneously using a single conveying track, which simplifies the equipment structure, reduces the failure rate of the conveying line, and shortens the time for the empty sterilization loading clamp to return to the sterilization chamber, thereby improving production efficiency.

[0018] (2) When the sterilization loading clamp containing the infusion bag moves on the clamp conveying track, it first passes through the clamp positioning mechanism located upstream of the clamp fixing device. The clamp positioning mechanism adjusts the spacing between multiple sterilization loading clamps that move synchronously by holding the base and the positioning plate, so that the spacing between two adjacent sterilization loading clamps is equal, and this spacing is equal to the spacing between two adjacent sterilization loading clamps in the clamp fixing device, so that after the clamp positioning mechanism drags all the sterilization loading clamps into the clamp fixing device, the clamp fixing device can accurately limit and fix each sterilization loading clamp;

[0019] (3) The number of bag-taking grippers on the bag-taking mechanism and the spacing between them are matched with the clamp fixing device, so that the bag-taking mechanism can remove the infusion bags from all the sterilization loading clamps in the clamp fixing device at the same time, which speeds up the bag-taking efficiency and avoids the sterilization loading clamps from staying in the clamp fixing device for too long.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc., used in this specification 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 application and simplifying the description, and do not indicate or imply that the device 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 on this application.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] As attached Figure 1-5 As shown, an automatic bag-loading and bag-removing device for a dual-chamber powder and liquid bag includes a clamp conveying track 1, a sterilization loading clamp 2, a clamp positioning mechanism 3, a clamp fixing device 4, and a bag-removing mechanism 5.

[0030] Both the clamp conveyor track 1 and the sterilization loading clamp 2 are existing devices in the art. One end of the clamp conveyor track 1 is located in the sterilization chamber, and the other end extends to the powder dispensing station. The sterilization loading clamp 2 is used to suspend and fix the infusion bag 6. Specifically, the empty sterilization loading clamp 2 loads the infusion bag 6 in the sterilization chamber, and then the sterilization loading clamp 2 conveys the infusion bag 6 to the powder dispensing station along the clamp conveyor track 1.

[0031] The clamp fixing device 4 is located at one end of the clamp conveying track 1 near the powder dispensing station. The clamp positioning mechanism 3 is located upstream of the clamp fixing device 4. That is, when the sterilization loading clamp 2 loaded with infusion bag 6 moves on the clamp conveying track 1, it first passes through the clamp positioning mechanism 3 and then enters the clamp fixing device 4.

[0032] Multiple sterilization loading clamps 2 can be simultaneously mounted on the clamp conveying track 1, and all sterilization loading clamps 2 move synchronously. In this embodiment, a total of four sterilization loading clamps 2 are provided.

[0033] The clamp positioning mechanism 3 includes a holding base 31, a positioning piece 32, a positioning detection element 33, and a power element 34. The clamp positioning mechanism 3 is used to drag all synchronously moving sterilization loading clamps 2 to the clamp fixing device 4, and the clamp positioning mechanism 3 can adjust the distance between the sterilization loading clamps 2.

[0034] The base 31 is kept as a long rod-shaped structure, with its length direction consistent with the conveying direction of the fixture conveying track 1, and the base 31 is kept above the fixture conveying track 1.

[0035] The positioning piece 32 is a paddle structure, with one end mounted on the holding base 31 and the other end retractable. When the four synchronously moving sterilization loading jigs 2 reach the jig positioning mechanism 3, the end of the positioning piece 32 away from the holding base 31 extends out and inserts into the gap between two adjacent sterilization loading jigs 2, so that each sterilization loading jig 2 has a positioning piece 32 on each side in the conveying direction.

[0036] The positioning plate 32 can be driven by a cylinder or powered by a power component 34, thereby causing the positioning plate 32 to move the sterilization loading fixture 2 along the holding base 31 to adjust its position, so that the distance between any two adjacent sterilization loading fixtures 2 is equal. During this process, the specific position of the four sterilization loading fixtures 2 is detected by four positioning detection components 33.

[0037] The power unit 34 provides power to the entire clamp positioning mechanism 3 to pull the four separated sterilization loading clamps 2 into the clamp fixing device 4. The power unit 34 may preferably be servo driven.

[0038] The clamp fixing device 4 is used to limit and fix all the sterilization loading clamps 2, preventing the sterilization loading clamps 2 from shifting during the process of unloading the infusion bag 6 from the sterilization loading clamps 2, which would lead to docking failure.

[0039] The clamp fixing device 4 includes a first fixing block 41, a second fixing block 42, and a frame 43.

[0040] The first fixing block 41 and the second fixing block 42 are both mounted on the frame 43, and the length of the first fixing block 41 is greater than that of the second fixing block 42. Both can move closer to or further away from the clamp conveying track 1 in a direction perpendicular to the conveying direction of the clamp conveying track 1. Specifically, when the first fixing block 41 and the second fixing block 42 are close to the clamp conveying track 1, the first fixing block 41 extends into the gap between two adjacent sterilization loading clamps 2 and abuts against the side walls of the two sterilization loading clamps 2, while the second fixing block 42 presses against the top of the sterilization loading clamp 2, thereby forming a limiting and fixing effect; when the first fixing block 41 and the second fixing block 42 are far away from the clamp conveying track 1, the first fixing block 41 and the second fixing block 42 release the sterilization loading clamp 2.

[0041] The distance between any two adjacent sterilization loading clamps 2 in the clamp fixing device 4 is equal, and this distance is equal to the distance between any two adjacent sterilization loading clamps 2 in the clamp positioning mechanism 3.

[0042] The bag-removing mechanism 5 is used to remove the infusion bag 6 from the sterilization loading clamp 2 in the clamp fixing device 4 and transfer it to the powder dispensing station.

[0043] The bag-removing mechanism 5 is equipped with bag-removing grippers 51, which are existing clamps specifically designed to hold the infusion bags 6 and are adapted to their shape and size. The number of bag-removing grippers 51 is equal to the number of sterilization loading clamps 2 that the clamp fixing device 4 can simultaneously fix, both being four. Furthermore, the distance between two adjacent sterilization loading clamps 2 in the clamp fixing device 4 is equal to the distance between two adjacent bag-removing grippers 51 on the bag-removing mechanism 5, thereby enabling the bag-removing mechanism 5 to simultaneously remove the infusion bags 6 from all the sterilization loading clamps 2 in the clamp fixing device 4.

[0044] After the sterilization loading clamp 2 removes the infusion bag 6, the clamp fixing device 4 releases the empty sterilization loading clamp 2. The empty sterilization loading clamp 2 returns to its initial position, i.e., the sterilization chamber, along the clamp conveying track 1. The empty sterilization loading clamp 2 then reloads the infusion bag 6 in the sterilization chamber before proceeding to the next transfer.

[0045] The implementation process of the above embodiments is as follows:

[0046] The sterilization loading clamp 2 loads the infusion bag 6 into the sterilization chamber, and then the sterilization loading clamp 2 conveys the infusion bag 6 to the powder dispensing station along the clamp conveyor track 1. During the movement of the four adjacent and synchronously moving sterilization loading clamps 2, they first pass through the clamp positioning mechanism 3. After the clamp positioning mechanism 3 separates the four sterilization loading clamps 2 and determines the distance between adjacent sterilization loading clamps 2, the clamp positioning mechanism 3 drags the four sterilization loading clamps 2 to the clamp fixing device 4. After the first fixing block 41 and the second fixing block 42 in the clamp fixing device 4 cooperate to limit and fix each sterilization loading clamp 2, the four bag-removing grippers 51 on the bag-removing mechanism 5 remove the infusion bag 6 from the sterilization loading clamp 2 in the clamp fixing device 4. Then, the first fixing block 41 and the second fixing block 42 release all the sterilization loading clamps 2, and the four empty sterilization loading clamps 2 return to the sterilization chamber along the clamp conveyor track 1 to load the infusion bag 6 again, thus completing the cycle.

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