Description

Technical Field

[0001] The utility model relates to the technical field of pre-filled sealing, and particularly relates to a bag body filling and sealing system. Background Art

[0002] With the gradual maturity of conventional fully automatic infusion equipment, the competition among pharmaceutical factories has intensified, putting forward higher requirements for equipment manufacturers. Only when the equipment has high efficiency, is convenient for commissioning and maintenance, has low cost, and good product quality can it be recognized by the market. At present, when the common fully automatic non-PVC bag-making and filling-sealing machine on the market is running, it relies on the synchronous belts driven by two sets of servo motors to transport the non-PVC film materials to the designated positions of each work station; in the past, with synchronous belt transportation, the distance between carriers cannot be changed, and the number of work stations at each processing station can only be kept the same. However, the time at each processing station is different, and the overall line efficiency is restricted by the filling station (the filling efficiency is the lowest), that is, the barrel effect.

[0003] How to effectively solve the technical problems that the production speed of the current automatic bag-making and filling-sealing machine is limited by its working principle and it is difficult to further improve to meet the market requirements and so on is an urgent problem for those skilled in the art in this field at present. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bag body filling and sealing system, which solves the problem of low bag-making and filling-sealing efficiency in the prior art.

[0005] The utility model is realized as follows: A bag body filling and sealing system includes a magnetic levitation conveying line. Along the magnetic levitation conveying line, a feeding mechanism, a bag opening mechanism, a filling mechanism, a sealing mechanism and a discharging mechanism are sequentially arranged. A plurality of carriers for fixing the bag body are arranged on the magnetic levitation conveying line; it is characterized in that a temporary storage area is arranged between the filling mechanism and the bag opening mechanism and the sealing mechanism. The bag opening mechanism, the filling mechanism and the sealing mechanism all include a plurality of processing workpieces for processing the bag body, and the number of processing workpieces on the filling mechanism is more than that of the bag opening mechanism and the sealing mechanism.

[0006] After the bag body is formed, the bag body is placed on the conveyor line through the feeding mechanism. The bag body successively completes bag opening, filling, and sealing on the conveyor line. After the product is formed, the product is output through the discharging mechanism. In the prior art, the bag body is placed on the conveyor line through the feeding mechanism. The conveyor line uses a circulating conveyor belt. The filling time is longer than that of other processes. Since the conveyor belt is a whole and cannot independently control the speed passing through each mechanism, it can only work according to the time of the filling process. Therefore, there is a problem of low efficiency. In the present invention, a temporary storage area is provided before and after the filling mechanism. The bag body processed by the bag opening mechanism enters the temporary storage area for temporary storage. Then, the bag opening mechanism continues to open the second batch of bag bodies. The bag bodies after bag opening are temporarily stored in the temporary storage area. After the number of bag bodies in the temporary storage area reaches the quantity requirement for processing by the filling mechanism, the bag bodies in the temporary storage area enter the filling mechanism according to the set quantity. Since the time-consuming during filling by the filling mechanism is longer than that of other processes, the number of workpieces processed by the filling mechanism is more than that of other mechanisms. Coupled with the fact that the conveyor line uses a maglev conveyor line that can independently control the conveying speed of the carrier, the problem of long filling process time of the filling mechanism can be effectively compensated, and the overall efficiency can be improved.

[0007] The bag body processed by the filling mechanism enters the buffer area between the filling mechanism and the sealing mechanism. When the number of soft bags processed by the filling mechanism in the buffer area reaches the processing quantity of the sealing mechanism, the bag body enters the sealing mechanism from the buffer area for sealing treatment. When each mechanism of the present invention is docked, it is in place and the time-consuming is effectively reduced compared with the prior art, thereby improving the efficiency.

[0008] A further technical solution of the present invention is that the maglev conveyor line includes a mover, the mover is connected to the carrier, and the bag body is placed between two carriers.

[0009] When the bag body is opened, the two sides of the bag body will move closer to the middle. In the prior art, a set of mechanisms for moving the bag body closer is required, which increases the complexity of the structure. In the present invention, a soft bag is connected to two movers. The two movers are respectively on both sides of the bag body. By moving the two movers closer to each other, the two sides of the bag body can be moved closer to the middle, thereby reducing the closer components and making the structure simpler.

[0010] A further technical solution of the present invention is that a nitrogen bag flushing mechanism is provided in the temporary storage area between the filling mechanism and the bag opening mechanism.

[0011] Before filling some products, nitrogen filling treatment is required. Since the nitrogen filling treatment takes a short time, the nitrogen flushing bag mechanism is arranged between the bag opening mechanism and the filling mechanism. This can make reasonable use of the situation that the temporary storage area needs to wait for a certain time for the number of bags to reach the requirement before entering the next mechanism. During this waiting time, the nitrogen filling treatment can be just fully utilized to complete. Through the above reasonable arrangement, it will not only not affect the smooth progress of the process but also further improve the efficiency.

[0012] A further technical solution of the present utility model is that a pipe interface feeding mechanism is provided in the temporary storage area between the filling mechanism and the sealing mechanism.

[0013] Some bags can be directly sealed, while some bags need to be connected with pipe interfaces before sealing. In view of the existing situation of connecting pipe interfaces, the present utility model arranges a pipe interface feeding mechanism in the temporary storage area between the filling and sealing mechanisms for the bags after being processed by the filling and sealing mechanism. Similarly, it can further improve the overall efficiency on the premise of ensuring the smooth progress of the process.

[0014] A further technical solution of the present utility model is that a pipe interface conveying line is arranged in parallel on the side of the magnetic levitation conveying line, and the pipe interface feeding mechanism is used to transfer the pipe interfaces on the pipe interface conveying line to the bags.

[0015] The pipe interface conveying line sequentially conveys the pipe interfaces to be docked with the pipe interface feeding mechanism. The pipe interface conveying line is arranged in parallel with the magnetic levitation conveying line, which makes it easier to feed the pipe interfaces and makes more reasonable use of space.

[0016] A further technical solution of the present utility model is that a waste kicking mechanism is provided between the sealing mechanism and the discharging mechanism.

[0017] Before the finished products are discharged, the unqualified products are kicked out to ensure the qualified rate of the finished products.

[0018] A further technical solution of the present utility model is that the magnetic levitation conveying line is a circulating conveying line.

[0019] The design of the circulating conveying line occupies less space.

[0020] Advantages of the present utility model: After the bag body is formed, the bag body is placed on the conveyor line through the feeding mechanism. The bag body sequentially completes bag opening, filling, and sealing on the conveyor line. After the product is formed, the product is output through the discharging mechanism. In the prior art, the bag body is placed on the conveyor line through the feeding mechanism. The conveyor line uses a circulating conveyor belt. The filling time is longer than that of other processes. Since the conveyor belt is an integral whole and the speed passing through each mechanism cannot be independently controlled, it can only work according to the time of the filling process. Therefore, there is a problem of low efficiency. In the present utility model, temporary storage areas are provided before and after the filling mechanism. The bag bodies processed by the bag opening mechanism enter the temporary storage area for temporary storage. Then, the bag opening mechanism continues to open the second batch of bag bodies. The bag bodies after bag opening are temporarily stored in the temporary storage area. After the number of bag bodies in the temporary storage area reaches the quantity requirement for processing by the filling mechanism, the bag bodies in the temporary storage area enter the filling mechanism according to the set quantity. Since the filling time when filling by the filling mechanism is longer than that of other processes, the number of workpieces processed by the filling mechanism is more than that of other mechanisms. Coupled with the fact that the conveyor line uses a maglev conveyor line that can independently control the conveying speed of the carrier, the problem of the long filling process time of the filling mechanism can be effectively compensated, and the effect of improving the overall efficiency can be achieved.

[0021] The bag bodies processed by the filling mechanism enter the buffer area between the filling mechanism and the sealing mechanism. When the number of soft bags processed by the filling mechanism in the buffer area reaches the processing quantity of the sealing mechanism, the bag bodies enter the sealing mechanism from the buffer area for sealing treatment. When each mechanism of the present utility model is docked, the cooperation is in place and the time consumed is effectively reduced compared with the prior art, thereby improving the efficiency.

[0033] Embodiment 1:

[0034] Figure 1-4 A bag body sealing system is shown, including a maglev conveyor line 1. Along the maglev conveyor line 1, a loading mechanism 2, a bag-opening mechanism 3, a filling mechanism 4, a sealing mechanism 5, and a blanking mechanism 6 are sequentially arranged. A plurality of carriers 7 for fixing the bag body 14 are arranged on the maglev conveyor line 1; a temporary storage area 8 is arranged between the filling mechanism 4 and the bag-opening mechanism 3 and the sealing mechanism 5. The bag-opening mechanism 3, the filling mechanism 4, and the sealing mechanism 5 all include a plurality of workpieces for processing the bag body. The number of workpieces on the filling mechanism 4 is more than the number of workpieces on the bag-opening mechanism 3 and the sealing mechanism 5.

[0035] In this embodiment, the feeding mechanism processes 6 workpieces, the bag opening mechanism processes 6 workpieces, the nitrogen filling bag mechanism processes 3 workpieces, the filling mechanism processes 8 workpieces, the pipe interface feeding mechanism processes 6 workpieces, the sealing mechanism processes 6 workpieces, the waste kicking mechanism processes 6 workpieces, and the discharging mechanism processes 6 workpieces.

[0036] In this embodiment, Figure 1 Area A is the bag making area, and area B is the bag body filling system area; the bag making film enters the workstations in the bag making area for processing, and a single bag body is obtained and enters area B of the bag body filling system.

[0037] In this embodiment, the magnetic levitation conveyor line 1 includes a mover, the mover is connected to the carrier 7, and the bag body 14 is placed between two carriers 7.

[0038] When the bag body is opened, the two sides of the bag body will move closer to the middle. In the prior art, a set of mechanisms for moving the bag body closer is required, which increases the complexity of the structure; in the present invention, a soft bag is connected to two movers, and the two movers are respectively on both sides of the bag body. By moving the two movers closer to each other, the two sides of the bag body can be moved closer to the middle, thus reducing the components for moving closer and making the structure simpler.

[0039] In this embodiment, a soft bag is connected to two carriers, the two carriers are respectively on both sides of the soft bag, and one carrier is connected to one mover.

[0040] In this embodiment, a nitrogen filling bag mechanism 9 is provided in the temporary storage area 8 between the filling mechanism 4 and the bag opening mechanism 3.

[0041] For some products, nitrogen filling treatment is required before filling. Since the time for nitrogen filling treatment is relatively fast, by arranging the nitrogen filling bag mechanism between the bag opening mechanism and the filling mechanism, the temporary storage area that needs to wait for a certain time to make the number of bag bodies reach the requirement before entering the next mechanism can be reasonably utilized. During this waiting time, the nitrogen filling treatment can be just fully utilized to complete; through the above reasonable arrangement, not only the smooth progress of the process will not be affected, but also the efficiency can be further improved.

[0042] In this embodiment, a pipe interface feeding mechanism 10 is provided in the temporary storage area 8 between the filling mechanism 4 and the sealing mechanism 5.

[0043] Some bag bodies can be directly sealed, while some bag bodies need to be connected with pipe interfaces before sealing. In view of the existing situation of connecting pipe interfaces, the present invention sets a pipe interface feeding mechanism in the temporary storage area between the filling and sealing mechanisms for the bag bodies after being processed by the filling and sealing mechanism. Similarly, on the premise of ensuring the smooth progress of the process, the overall efficiency can be further improved.

[0044] In this embodiment, a pipe interface conveyor line 12 is arranged in parallel on the side of the magnetic levitation conveyor line 1, and the pipe interface loading mechanism 10 is used to transfer the pipe interfaces on the pipe interface conveyor line 12 to the bag body 14.

[0045] The pipe interface conveyor line sequentially conveys the pipe interfaces to be docked with the pipe interface loading mechanism. The pipe interface conveyor line is arranged parallel to the magnetic levitation conveyor line, which makes it easier to load the pipe interfaces and makes more reasonable use of space.

[0046] In this embodiment, a waste kicking mechanism 11 is arranged between the sealing mechanism 5 and the discharging mechanism 6.

[0047] Before the finished products are discharged, the unqualified products are kicked out to ensure the qualified rate of the finished products.

[0048] In this embodiment, the magnetic levitation conveyor line 1 is a circulating conveyor line.

[0049] The design of the circulating conveyor line occupies little space.

[0050] In this embodiment, an outlet mesh belt 13 is arranged in parallel on one side of the magnetic levitation conveyor line, and the discharging mechanism is used to transfer the bag body 14 on the magnetic levitation conveyor line to the outlet mesh belt 13 to complete the discharging.

[0051] Working principle of the present utility model: After the bag body is formed, the bag body is placed on the conveyor line through the loading mechanism. The bag body sequentially completes bag opening, filling, and sealing on the conveyor line. After the product is formed, the product is output through the discharging mechanism; in the prior art, the bag body is placed on the conveyor line through the loading mechanism. The conveyor line uses a circulating conveyor belt, and the filling time is longer than that of other processes. Since the conveyor belt is a whole and cannot independently control the speed of passing through each mechanism, it can only work according to the time of the filling process. Therefore, there is a problem of low efficiency; in the present utility model, a temporary storage area is arranged before and after the filling mechanism. The bag body after being processed by the bag opening mechanism enters the temporary storage area for temporary storage, and then the bag opening mechanism continues to open the second batch of bag bodies. The bag bodies after being opened are stored in the temporary storage area. After the number of bag bodies in the temporary storage area reaches the quantity requirement for processing by the filling mechanism, the bag bodies in the temporary storage area enter the filling mechanism according to the set quantity; since the time consumed during filling by the filling mechanism is longer than that of other processes, the number of workpieces processed by the filling mechanism is more than that of other mechanisms. Combined with the magnetic levitation conveyor line whose carrier conveying speed can be independently controlled, the problem of long filling process time of the filling mechanism can be effectively compensated, and the effect of improving the overall efficiency can be achieved.

[0052] The bag body processed by the filling mechanism enters the buffer area between the filling mechanism and the sealing mechanism. When the number of soft bags processed by the filling mechanism in the buffer area reaches the processing quantity of the sealing mechanism, the bag body enters the sealing mechanism from the buffer area for sealing treatment. When the various mechanisms of the present utility model are docked, they are in place in cooperation and the time consumed can be effectively reduced compared with the prior art, thereby improving the efficiency.

[0053] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
