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, nested boxes have become a standardized container for storing and transporting injection vials. The standardized design of nested boxes allows injection vials to be handled directly in the nested box, eliminating the need to transfer individual bottles. During the filling and packaging process, the nested box design prevents contact between glass containers, maintaining the high quality and durability of the injection vials. Furthermore, wash-free and sterilization-free products are pre-sterilized, eliminating the need for cleaning, siliconizing machines, and tunnel ovens, significantly simplifying the traditional filling process and improving filling efficiency. New filling equipment developed based on nested boxes integrates multiple workstations on the production line, including unpacking, unpacking, de-nesting, filling, stoppering, and returning to the nest.

[0003] The blocker is a device for blocking materials. The existing blocker is described in the Chinese patent document with application number 201910133202.6, which specifically discloses: a blocking part, which includes a blocking part base, a blocking wheel and a buffer part. The blocking wheel is provided at one end of the blocking part base for blocking materials on the assembly line, and the buffer part is provided 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 it, 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 blocker described in the above patent has the following deficiencies:

[0004] 1) The blocking wheel needs to be moved back to the blocking position under the action of the telescopic rod. The position of the material needs to be detected by a detection mechanism 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 backward. On the one hand, it is easy to crush the material behind it. On the other hand, it causes the material behind it to move backward, 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

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a pre-filled production system and method with low control difficulty, low cost, convenience for nest box transportation, convenience for orderly filling at filling stations, convenience for overall orderly production, and improvement of production efficiency.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A pre-filled production system includes a nest box conveying mechanism and a film tearing station, a filling loading station and a filling station sequentially arranged along the conveying direction of the nest box conveying mechanism;

[0010] The filling and loading station includes a waiting area and a loading area, a nest box blocking device is arranged between the waiting area and the loading area of ​​the filling and loading station, and a material detection mechanism electrically connected to the nest box blocking device is provided in the loading area;

[0011] The nest box blocking device includes a driving mechanism and a blocking mechanism, the driving mechanism is arranged below the nest box conveying mechanism, the blocking mechanism includes a swing frame and an elastic member, the swing frame is swingably arranged on the driving mechanism, the driving mechanism is used to drive the swing frame to rise and fall, one end of the swing frame is suspended to form a blocking end, and the elastic member is arranged between the swing frame and the driving mechanism, and is used to make the blocking end rise to above the conveying plane of the nest box conveying mechanism to block the nest box.

[0012] As a further improvement of the above technical solution:

[0013] The driving mechanism is provided with a support frame, which is arranged on the driving mechanism in a liftable manner; the swing frame is swingably arranged on the support frame, and the driving mechanism drives the support frame to lower the blocking end so that the nest box passes through the nest box blocking device.

[0014] An adjusting screw is provided at the bottom of the support frame. At least two fixing nuts are provided on the adjusting screw. The two fixing nuts are clamped on the driving mechanism.

[0015] The driving mechanism is provided with a connecting component that can be adjusted to rise and fall, the elastic member is arranged between the swing frame and the connecting component, the connecting component includes a connecting screw, and the connecting screw is provided with at least two locking nuts. The two locking nuts are clamped on the driving mechanism, and the elastic member is arranged between the swing frame and the connecting screw.

[0016] The middle part of the swing frame is rotatably connected to the support frame. A limiting member for limiting the swing position of the swing frame is provided below the swing frame, and a blocking roller is provided at the blocking end.

[0017] The driving mechanism is fixedly arranged on the supporting frame, the swing frame is swingably arranged on the supporting frame, the elastic member is arranged between the driving mechanism and the swing frame, and the driving mechanism drives the limiting member to swing the swing frame relative to the supporting frame, and causes the blocking end to drop below the conveying plane of the nest box conveying mechanism to release the nest box.

[0018] The material detection mechanism is connected to the driving mechanism signal, and the driving mechanism determines the descending time of the nest box blocking device according to the signal of the material detection mechanism.

[0019] The conveying mechanism comprises a first conveying mechanism and a second conveying mechanism which 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.

[0020] A prefilling production method using the above-mentioned prefilling production system comprises the following steps:

[0021] S1: placing the nest box on the nest box conveying mechanism, which conveys the nest box to the film tearing station to tear off the outer film of the nest box;

[0022] S2: The nest box with the film torn off is transported to the filling and loading station by the nest box conveying mechanism, and the nest box with the film torn off is blocked in the waiting area by the nest box blocking device provided at the filling and loading station;

[0023] S3: The material detection mechanism detects the status of the nest box in the loading area. When no nest box is detected in the loading area, a start signal is sent to the nest box blocking device, causing the driving mechanism to drive the swing frame to descend and release the nest box to the loading area;

The time t is less than the time required for the nest box conveying mechanism to travel the width of the nest box;

[0025] S5: Filling the containers in the nest box at the filling station.

[0028] Compared with the prior art, the advantages of the present invention are:

[0029] This pre-filled packaging production system, firstly, utilizes a nest box blocking device to block and release nest boxes. The blocking requirements for nest boxes can be met by simply raising and lowering the swing frame, eliminating the need for a detection mechanism to detect the nest box's position and determine whether the swing frame has returned to its original position. This system features a simple overall structure, minimal control difficulty, and low cost. Secondly, during the swing frame's lowering and release process, the blocking end does not move backward, thus minimizing the risk of damaging the nest box behind it or causing it to shift backward, facilitating nest box transport. Thirdly, after a nest box passes the blocking end of the nest box blocking device for a set time period, t, the drive mechanism drives the swing frame upward, causing the blocking end to be supported against the bottom surface of the nest box above it by the elastic force of an elastic member. This time period, t, is less than the time required for the nest box conveying mechanism to travel the width of the nest box. Consequently, after a nest box passes the blocking end, the blocking end, under the elastic force of the elastic member, rises above the conveying plane of the nest box conveying mechanism to block the next nest box. This achieves timely blocking of the next nest box without requiring an external driving force, resulting in a simple and ingenious structural design. Fourthly, the material detection mechanism detects the status of the nest boxes in the loading area and controls the lifting and lowering of the swing frame to release the nest boxes, so that the nest boxes are released one by one according to the situation in the loading area, avoiding the accumulation of nest boxes at the filling station, which is conducive to orderly filling at the filling station, and is conducive to overall orderly production and improved production efficiency.

[0030] The prefilling production method adopts a prefilling production system and has all the advantages of the prefilling production system. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example 1:

[0042] Figures 1 to 3 An embodiment of the pre-filled packaging production system of the present invention is shown. The pre-filled 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 material loading area 622. The nest box blocking device is arranged between the material waiting area 621 and the material loading area 622 of the filling and loading station 62. The material detection mechanism 7 electrically connected to the nest box blocking device is provided in the material loading area 622.

[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 set 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 is as follows: Figure 4 As shown,

[0046] Step 1: Place the nest box 3 on the nest box conveying mechanism 6, which 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 boxes 3 are transported to the filling and loading station 62 by the nest box conveying mechanism 6, and the torn nest boxes 3 are blocked in the waiting area 621 by the nest box blocking device provided 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 (as shown in FIG. Figure 4 As 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 t is less than the time required for the nest box conveying mechanism 6 to travel the nest box width; in this way, when the nest box 3 passes 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, 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] Firstly, this pre-filled packaging production system utilizes a nest box retaining and releasing device to retain and release nest boxes 3. The retaining and releasing requirements of the nest boxes 3 can be met simply by raising and lowering the swing frame 22. There is no need for a detection mechanism to detect the position of the nest boxes 3 and determine whether the swing frame 22 has returned to its original position. This system has a simple overall structure, low control difficulty, and low cost. Secondly, during the release process of the swing frame 22, the retaining end 221 does not move rearward, which is unlikely to damage the nest boxes 3 behind, nor will it cause the nest boxes 3 to move backward, thus facilitating the transport of the nest boxes 3. Third, after a nest box 3 passes the blocking end 221 of the nest box blocking device for a set time period t, the drive mechanism 1 drives the swing frame 22 upward, causing the blocking end 221 to be supported on the bottom surface of the nest box 3 above it under the elastic force of the elastic member 23. The time period t is less than the time required for the nest box conveying mechanism 6 to travel the nest box width. Thus, after the nest box 3 passes the blocking end 221, the blocking end 221 is immediately lifted 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. This achieves timely blocking of the next nest box 3 without the need for external driving force, resulting in a simple and ingenious structural design. Fourth, the material detection mechanism 7 detects the status of the nest boxes 3 in the loading area 622 and controls the swing frame 22 to raise and lower the nest boxes 3. This allows the nest boxes 3 to be released one by one according to the status of the loading area 622, thus preventing the nest boxes 3 from accumulating at the filling station 63, facilitating orderly filling at the filling station 63, and promoting overall orderly production, thereby improving production efficiency.

[0052] Further, if Figure 2 and Figure 3 As shown, in this embodiment, the drive mechanism 1 is provided with a support frame 21, which is arranged to be raised and lowered on the drive mechanism 1; the swing frame 22 is swingably mounted on the support frame 21. The drive mechanism 1 drives the support frame 21 to lower the blocking end 221, allowing the nest box 3 to pass through the nest box blocking device. The drive mechanism 1 drives the swing frame 22 to rise and fall as a whole. That is, the swing frame 22 has an overall lifting motion and a swinging motion that overcomes the elastic member 23, meeting the requirements of releasing the front nest box 3 and timely blocking the rear nest box 3.

[0053] Further, if Figure 3 As shown, in this embodiment, an adjusting screw 211 is provided at the bottom of the support frame 21. The adjusting screw 211 is provided with at least two fixing nuts 212, which are clamped to the drive mechanism 1. In this way, the height of the swing center of the swing frame 22 from the drive mechanism 1 can be adjusted by screwing the fixing nuts 212, thereby meeting the requirements of different heights of the blocking and releasing device, thereby improving adaptability.

[0054] Furthermore, in this embodiment, the drive mechanism 1 is provided with a connection assembly 4 that can be adjusted in height, and an elastic member 23 is disposed between the swing frame 22 and the connection assembly 4. By adjusting the height of the connection assembly 4, the pre-applied elastic force of the elastic member 23 when the blocking end 221 is supported against 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 assembly 4 includes a connecting screw 41, which is provided with at least two locking nuts 42. The two locking nuts 42 are clamped to the drive mechanism 1. The elastic member 23 is disposed between the swing frame 22 and the connection screw 41. The height of the connecting screw 41 can be adjusted by screwing the locking nuts 42, thereby achieving the height adjustment of the connection assembly 4. This has a simple structure and is easy to adjust.

[0055] Furthermore, in this embodiment, the middle portion of the swing frame 22 is rotatably connected to the support frame 21. A stopper 5 is provided below the swing frame 22 to limit the swing position of the swing frame 22. A blocking roller 24 is provided at the blocking end 221. The blocking roller 24 supports the blocking end 221 against the bottom surface of the nest box 3 above it, reducing friction. The stopper 5 limits the swing position of the swing frame 22 and prevents the blocking end 221 from tilting upward excessively. Preferably, the elastic member 23 is a spring.

[0056] Furthermore, in this embodiment, the material detection mechanism 7 is signal-connected to the drive mechanism 1, and the drive mechanism 1 determines the time to lower the nest box retaining device based on the signal from the material detection mechanism 7. When the material detection mechanism 7 does not detect the presence of a nest box 3 in the loading area 622, the material detection mechanism 7 sends a start signal to the nest box retaining device, causing the drive mechanism 1 to drive the swing frame 22 downward to release the nest box 3 into 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, which are connected in sequence and move independently of each other. The nest box blocking device is located 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. Thus, 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 operate to convey the previous nest box 3 forward, and the first conveying mechanism 601 can stop operating, thereby reducing wear on the blocked nest box 3. Specifically, the first conveying mechanism 601 and the second conveying mechanism 602 are collinear, that is, they convey in the same direction. The film tearing station 61 is located on the first conveying mechanism 601, and the filling and loading station 62 and the filling station 63 are located on the second conveying mechanism 602.

[0058] Example 2:

[0059] Another embodiment of the prefilled packaging production system of the present invention has a structure that is basically the same as that of the first embodiment, with the only difference being that: the driving mechanism 1 is fixedly arranged on the support frame 21, the swing frame 22 is swingably arranged on the support frame 21, and the elastic member 23 is arranged between the driving mechanism 1 and the swing frame 22. The driving mechanism 1 drives the limit member 5 to swing the swing frame 22 relative to the support frame 21, and causes the blocking end 221 to descend below the conveying plane of the nest box conveying mechanism 6 to release the nest box 3.

[0060] Example 3:

[0061] A prefilled product production method, using the prefilled product production system of Example 1 or Example 2, comprises the following steps:

[0062] S1: placing the nest box 3 on the nest box conveying mechanism 6, which conveys the nest box 3 to the film tearing station 61 to tear off the outer film of the nest box 3;

[0063] S2: The torn nest boxes 3 are transported to the filling and loading station 62 by the nest box conveying mechanism 6, and the torn nest boxes 3 are blocked in the waiting area 621 by the nest box blocking device provided 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 As 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 t is less than the time required for the nest box conveying mechanism 6 to travel the nest box width; in this way, when the nest box 3 passes 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, 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 a prefilling production system and has all the advantages of the prefilling production system.

[0068] First, the nest box blocking and releasing device is used to block and release the nest box 3. The blocking and releasing requirements of the nest box 3 can be met by simply raising 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, which reduces the control difficulty and cost. Second, during the release process of the swing frame 22, the blocking end 221 will not move backward, which is not likely to damage the rear nest box 3 and will not cause the rear nest box 3 to move backward, thereby facilitating the transportation of the nest box 3. Third, after a nest box 3 passes the blocking end 221 of the nest box blocking device for a set time period t, the drive mechanism 1 drives the swing frame 22 upward, causing the blocking end 221 to be supported on the bottom surface of the nest box 3 above it under the elastic force of the elastic member 23. The time period t is less than the time required for the nest box conveying mechanism 6 to travel the nest box width. Thus, after the nest box 3 passes the blocking end 221, the blocking end 221 is immediately lifted 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. This achieves timely blocking of the next nest box 3 without the need for external driving force, resulting in a simple and ingenious structural design. Fourth, the material detection mechanism 7 detects the status of the nest boxes 3 in the loading area 622 and controls the swing frame 22 to raise and lower the nest boxes 3. This allows the nest boxes 3 to be released one by one according to the status of the loading area 622, thus preventing the nest boxes 3 from accumulating at the filling station 63, facilitating orderly filling at the filling station 63, and promoting overall orderly production, thereby improving 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 out 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;

[0072] After the nest box 3 partially passes the blocking end 221 for a set time, 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.
