Description

Technical Field

[0001] The present invention relates to the technical field of food and medicine packaging machinery and equipment, and in particular to a pre-filling production system and method. Background Art

[0002] In the pharmaceutical industry, nest boxes have become a standardized container for storing and transporting injection bottles. The standardized design of nest boxes allows injection bottles to be handled directly in the nest boxes without transferring individual bottles. During the filling and packaging process, the nest box design avoids contact between glass containers and maintains the high quality and durability of injection bottles. In addition, the wash-free and sterilization-free products are pre-sterilized and no longer require equipment such as cleaning and siliconizing machines and tunnel ovens, which greatly simplifies the traditional filling process and improves filling efficiency. The new filling equipment is developed based on the nest box, and the production line integrates multiple stations such as unpacking, unpacking, unnesting, filling, plugging, and returning to the nest.

[0003] The blocker is a device for blocking materials. The existing blocker, as recorded in the Chinese patent document with application number 201910133202.6, specifically discloses: a blocking part, which includes a blocking part base, a blocking wheel and a buffer part. The blocking wheel is arranged at one end of the blocking part base for blocking materials on the assembly line, and the buffer part is arranged at the other end of the blocking part base for shock absorption; a connecting rod part, which is located below the blocking part and fixedly connected to the blocking part, and is used to drive the blocking part to rise and fall, and the inner end of the connecting rod part is hinged to the assembly line frame through the first base; a driving part, which is located below the connecting rod part and is hinged to the middle part of the connecting rod part, and is used to drive the connecting rod part to rise and fall, and the driving part is hinged to the assembly line frame through the second base. The existing blockers recorded in the aforementioned patent have the following deficiencies:

[0004] 1) The blocking wheel needs to be moved back to the blocking position under the action of the telescopic rod, and the detection mechanism needs to be used to detect the position of the material to determine whether the blocking wheel has returned to its position, resulting in a complex overall structure, difficult control, and high cost;

[0005] 2) When the telescopic rod pulls down the blocking wheel to release the blocking effect, the blocking wheel will move backwards. On the one hand, it is easy to crush the materials at the rear. On the other hand, it causes the materials at the rear to move backwards, which is not conducive to material transportation.

[0006] When the barrier in the prior art is applied to a pre-filling production line, complex control logic and control equipment are required to control the nest box to arrive at a specific station at a specific time and stay at the specific station for a specific time. Summary of the invention

[0041] Embodiment 1:

[0042] Figures 1 to 3 An embodiment of the prefilled packaging production system of the present invention is shown. The prefilled packaging production system of this embodiment includes a nest box conveying mechanism 6 and a film tearing station 61, a filling loading station 62 and a filling station 63 arranged in sequence along the conveying direction of the nest box conveying mechanism 6;

[0043] The filling and loading station 62 includes a material waiting area 621 and a loading area 622. The nest box blocking device is arranged between the material waiting area 621 and the loading area 622 of the filling and loading station 62. The loading area 622 is provided with a material detection mechanism 7 which is electrically connected to the nest box blocking device.

[0044] The nest box blocking device includes a driving mechanism 1 and a blocking mechanism 2. The driving mechanism 1 is arranged below the nest box conveying mechanism 6. The blocking mechanism 2 includes a swing frame 22 and an elastic member 23. The swing frame 22 is swingably arranged on the driving mechanism 1. The driving mechanism 1 is used to drive the swing frame 22 to rise and fall. One end of the swing frame 22 is suspended to form a blocking end 221. The elastic member 23 is arranged between the swing frame 22 and the driving mechanism 1, and is used to make the blocking end 221 rise to above the conveying plane of the nest box conveying mechanism 6 to block the nest box 3.

[0045] The production process of this prefilled production system, such as Figure 4 As shown,

[0046] Step 1: placing the nest box 3 on the nest box conveying mechanism 6, and the nest box conveying mechanism 6 conveys the nest box 3 to the film tearing station 61 to tear off the outer film of the nest box 3;

[0047] Step 2: The torn nest box 3 is transported to the filling and loading station 62 by the nest box conveying mechanism 6, and the torn nest box 3 is blocked in the waiting area 621 by the nest box blocking device arranged at the filling and loading station 62;

[0048] Step 3: The material detection mechanism 7 detects the state of the nest box 3 in the loading area 622. When no nest box 3 is detected in the loading area 622, a start signal is sent to the nest box blocking device to make the driving mechanism 1 drive the swing frame 22 to descend (such as Figure 4 (shown in a2) releasing the nest box 3 to the loading area 622;

[0049] Step 4: After the nest box 3 passes through the blocking end 221 of the nest box blocking device for a set time t, the driving mechanism 1 drives the swing frame 22 to rise, so that the blocking end 221 is supported on the bottom surface of the upper nest box 3 under the elastic force of the elastic member 23 (such as Figure 4 As shown in a3 in the figure, the time length t is less than the time required for the nest box conveying mechanism 6 to travel the nest box width; thus, when the nest box 3 passes the blocking end 221, the blocking end 221 will rise to above the conveying plane of the nest box conveying mechanism 6 under the elastic force of the elastic member 23 to block the next nest box 3, as shown in a3 in the figure. Figure 4 As shown in a4 and a5.

[0050] Step 5: Fill the containers in the nest box 3 at the filling station 63 .

[0051] In the first aspect, the pre-filled production system adopts a nest box blocking device to block and release the nest box 3. The blocking and releasing requirements of the nest box 3 can be met by lifting and lowering the swing frame 22. There is no need to use a detection mechanism to detect the position of the nest box 3 to determine whether the swing frame 22 has returned to its original position. The overall structure is simple, the control difficulty is small, and the cost is low. In the second aspect, during the release process of the swing frame 22 descending, the blocking end 221 will not move backward, and it is not easy to damage the rear nest box 3, nor will it cause the rear nest box 3 to move backward, which is conducive to the transportation of the nest box 3. Thirdly, after the nest box 3 passes through the blocking end 221 of the nest box blocking device for a set time t, the driving mechanism 1 drives the swing frame 22 to rise, so that the blocking end 221 is supported on the bottom surface of the upper nest box 3 under the elastic force of the elastic member 23, and the time t is less than the time required for the nest box conveying mechanism 6 to travel the nest box width; in this way, after the nest box 3 passes through the blocking end 221, the blocking end 221 will rise to the top of the conveying plane of the nest box conveying mechanism 6 under the elastic force of the elastic member 23 to block the next nest box 3, which not only achieves the timely blocking of the next nest box 3, but also does not need to be driven by an external driving force, and the structural design is simple and ingenious. Fourthly, the material detection mechanism 7 detects the state of the nest box 3 in the feeding area 622, controls the swing frame 22 to rise and fall to block and release the nest box 3, so that the nest box 3 releases the nest box 3 one by one according to the situation in the feeding area 622, avoids the accumulation of the nest box 3 in the filling station 63, is conducive to the orderly filling of the filling station 63, is conducive to the overall orderly production, and improves the production efficiency.

[0052] Furthermore, if Figure 2 and Figure 3 As shown, in this embodiment, the driving mechanism 1 is provided with a support frame 21, and the support frame 21 is arranged on the driving mechanism 1 in a lifting manner; the swing frame 22 is swingably arranged on the support frame 21, and the driving mechanism 1 drives the support frame 21 to lower the blocking end 221 so that the nest box 3 passes through the nest box blocking device. The driving mechanism 1 drives the swing frame 22 to rise and fall as a whole, that is, the swing frame 22 has an overall lifting movement and a swinging movement that overcomes the elastic member 23, which meets the requirements of releasing the front nest box 3 and timely blocking the rear nest box 3.

[0053] Furthermore, if Figure 3 As shown, in this embodiment, an adjusting screw 211 is provided at the bottom of the support frame 21, and at least two fixing nuts 212 are provided on the adjusting screw 211, and the two fixing nuts 212 are clamped on the driving mechanism 1. In this way, the height of the swing center of the swing frame 22 from the driving mechanism 1 can be adjusted by screwing the fixing nuts 212, so as to meet the requirements of blocking at different heights and improve adaptability.

[0054] Furthermore, in this embodiment, a connection component 4 that can be adjusted in height is provided on the driving mechanism 1, and an elastic member 23 is provided between the swing frame 22 and the connection component 4. By adjusting the height of the connection component 4, the pre-elastic force of the elastic member 23 when the blocking end 221 is supported on the bottom surface of the upper nest box 3 can be adjusted to meet the time requirement for the blocking end 221 to rise. Specifically, the connection component 4 includes a connecting screw 41, and at least two locking nuts 42 are provided on the connecting screw 41. The two locking nuts 42 are clamped on the driving mechanism 1, and the elastic member 23 is provided between the swing frame 22 and the connection screw 41. The lifting height of the connecting screw 41 can be adjusted by screwing the locking nut 42, thereby realizing the lifting and lowering adjustment of the connection component 4, which has a simple structure and is easy to adjust.

[0055] Furthermore, in this embodiment, the middle part of the swing frame 22 is rotatably connected to the support frame 21, and a limiter 5 for limiting the swing position of the swing frame 22 is provided below the swing frame 22, and a blocking roller 24 is provided at the blocking end 221. The blocking end 221 is supported on the bottom surface of the upper nest box 3 by the blocking roller 24 to reduce friction. The limiter 5 is used to limit the swing position of the swing frame 22 to prevent the blocking end 221 from tilting up excessively. Preferably, the elastic member 23 is a spring.

[0056] Furthermore, in this embodiment, the material detection mechanism 7 is connected to the drive mechanism 1 by signal, and the drive mechanism 1 determines the descending time of the nest box blocking device according to the signal of the material detection mechanism 7. When the material detection mechanism 7 does not detect the presence of the nest box 3 in the loading area 622, the material detection mechanism 7 sends a start signal to the nest box blocking device, so that the drive mechanism 1 drives the swing frame 22 to descend and release the nest box 3 to the loading area 622.

[0057] Furthermore, if Figure 1 As shown, in this embodiment, the nest box conveying mechanism 6 includes a first conveying mechanism 601 and a second conveying mechanism 602 that are connected in sequence and move independently of each other, and the nest box blocking device is arranged at the rear end of the first conveying mechanism 601 in the conveying direction. The first conveying mechanism 601 and the second conveying mechanism 602 move independently of each other, so that when the nest box blocking device releases the previous nest box 3 and then blocks the next nest box 3, the second conveying mechanism 602 continues to run to convey the previous nest box 3 forward, and the first conveying mechanism 601 can stop running to reduce the wear on the blocked nest box 3. Specifically, the first conveying mechanism 601 and the second conveying mechanism 602 are in the same line, that is, the conveying direction is the same, the film tearing station 61 is arranged on the first conveying mechanism 601, and the filling and loading station 62 and the filling station 63 are arranged on the second conveying mechanism 602.

[0058] Embodiment 2:

[0063] S2: The torn nest box 3 is transported to the filling and loading station 62 by the nest box conveying mechanism 6, and the torn nest box 3 is blocked in the waiting area 621 by the nest box blocking device arranged at the filling and loading station 62;

[0064] S3: The material detection mechanism 7 detects the state of the nest box 3 in the loading area 622. When no nest box 3 is detected in the loading area 622, a start signal is sent to the nest box blocking device to make the driving mechanism 1 drive the swing frame 22 to descend (such as Figure 4 (shown in a2) releasing the nest box 3 to the loading area 622;

[0065] S4: After the nest box 3 passes through the blocking end 221 of the nest box blocking device for a set time t, the driving mechanism 1 drives the swing frame 22 to rise, so that the blocking end 221 is supported on the bottom surface of the upper nest box 3 under the elastic force of the elastic member 23 (such as Figure 4 As shown in a3 in the figure, the time length t is less than the time required for the nest box conveying mechanism 6 to travel the nest box width; thus, when the nest box 3 passes the blocking end 221, the blocking end 221 will rise to above the conveying plane of the nest box conveying mechanism 6 under the elastic force of the elastic member 23 to block the next nest box 3, as shown in a3 in the figure. Figure 4 As shown in a4 and a5.

[0066] S5: Filling the containers in the nest box 3 at the filling station 63 .

[0067] The prefilling production method adopts the prefilling production system and has all the advantages of the prefilling production system.

[0068] First, the nest box blocking device is used to block and release the nest box 3, and the blocking and releasing requirements of the nest box 3 can be met by lifting and lowering the swing frame 22. There is no need to use a detection mechanism to detect the position of the nest box 3 to determine whether the swing frame 22 has returned to its original position. The control difficulty is small and the cost is low. Second, during the release process of the swing frame 22 descending, the blocking end 221 will not move backward, and it is not easy to damage the rear nest box 3, nor will it cause the rear nest box 3 to move backward, which is conducive to the transportation of the nest box 3. Thirdly, after the nest box 3 passes through the blocking end 221 of the nest box blocking device for a set time t, the driving mechanism 1 drives the swing frame 22 to rise, so that the blocking end 221 is supported on the bottom surface of the upper nest box 3 under the elastic force of the elastic member 23, and the time t is less than the time required for the nest box conveying mechanism 6 to travel the nest box width; in this way, after the nest box 3 passes through the blocking end 221, the blocking end 221 will rise to the top of the conveying plane of the nest box conveying mechanism 6 under the elastic force of the elastic member 23 to block the next nest box 3, which not only achieves the timely blocking of the next nest box 3, but also does not need to be driven by an external driving force, and the structural design is simple and ingenious. Fourthly, the material detection mechanism 7 detects the state of the nest box 3 in the feeding area 622, controls the swing frame 22 to rise and fall to block and release the nest box 3, so that the nest box 3 releases the nest box 3 one by one according to the situation in the feeding area 622, avoids the accumulation of the nest box 3 in the filling station 63, is conducive to the orderly filling of the filling station 63, is conducive to the overall orderly production, and improves the production efficiency.

[0069] Furthermore, in this embodiment, the nest box 3 is manually placed on the nest box conveying mechanism 6 .

[0070] Specifically, when the material detection mechanism 7 detects that the filling and loading station 62 is short of material, it sends a discharge signal to the driving mechanism 1;

[0071] After receiving the discharge signal, the driving mechanism 1 drives the swing frame 22 to descend, so that the blocking end 221 descends to below the conveying plane of the nest box conveying mechanism 6;
