Description

Technical Field

[0001] This utility model relates to the field of nest box transfer technology, specifically a nest box transfer device. Background Technology

[0002] In the field of aseptic production of pharmaceuticals, biological products and medical devices, pre-filled syringes, vials and other packaging materials are often packaged in nested or pallet form and sealed in sterile outer bags. Before entering the aseptic filling or processing line, the packaging material, i.e. the nest box itself, needs to be sterilely and efficiently removed from its outer protective bag and transferred to the downstream conveying system, such as a conveyor belt. This process is called "nest box transfer".

[0003] Existing nest box transfer devices use moving parts that grip or push the nest box during the transfer process, such as existing technology. Figure 1 The grippers and pushers shown are typically positioned above or to the side of the nest box for operation.

[0004] After the nest box is placed on the downstream conveyor belt, the area above it is often blocked by the robotic arm, gripper or other support structure of the transfer device. This hinders the efficient airflow, such as unidirectional flow or first-pass air, from fully and evenly sweeping the surface of the nest box, making it difficult to effectively remove any particles that may be present. This fails to meet the requirement that the "first-pass air sweeping" should directly act on the surface of the product or packaging material.

[0005] Meanwhile, in order to achieve the functions of gripping, transferring and releasing, existing devices usually require multiple sets of drives, such as X / Y / Z linear drives, rotary drives and complex linkage mechanisms. These mechanisms are often arranged on the side or top of the nest box, resulting in a large and not compact overall structure of the equipment, occupying cleanroom space and increasing the possibility of mechanical interference. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a nest box transfer device, which solves the problems mentioned in the background.

[0007] This utility model provides the following technical solution: a nest box transfer device, comprising: a connecting frame, a linear drive component mounted on a workbench, and a clamping assembly for holding the nest box body;

[0008] A flipping assembly is mounted on a moving block of a linear drive component. A connecting frame is mounted on the flipping assembly, and a clamping box assembly is mounted on the connecting frame. One end of the flipping assembly is connected to a flipping element, which drives the clamping box assembly to flip 90°.

[0009] After the clamping box assembly completes the transfer of the nest box body to the conveyor belt position on the worktable, the flipping component drives the flipping assembly and the clamping box assembly to flip to the position below the direction of movement of the nest box body, and a safe gap is formed between the clamping box assembly and the bottom of the nest box body.

[0010] Preferably, the clamping box assembly includes a fixing plate and a clamping cylinder. The fixing plate is installed on the top of the connecting frame, the clamping cylinder is installed on the top of the fixing plate, a first clamping plate is connected to the side of the fixing plate, and a second clamping plate is installed at the telescopic end of the clamping cylinder. The surface of the first clamping plate is connected to the surface of the second clamping plate.

[0011] Preferably, the flipping assembly includes a flipping shaft, a connecting plate is mounted on the moving block of the linear drive, bearing seats are symmetrically arranged on the top of the connecting plate, the surface of the flipping shaft is connected to the inner wall of the bearing seats, a connecting frame is mounted on the surface of the flipping shaft, and the connecting frame is mounted on the surface of the connecting frame.

[0012] Preferably, the flipping component consists of two parallel cam track plates mounted on a worktable. Mounting plates are installed at both ends of the flipping shaft, and cam followers are mounted on the surface of the mounting plates. The cam followers are connected to the track grooves of the cam track plates. When the linear drive component drives the flipping shaft to move along the Y direction, the cam followers move along the track grooves and drive the flipping shaft to rotate.

[0013] Preferably, the flipping component is a rotary drive unit, which is mounted on the moving block of the linear drive component, and the output shaft of the rotary drive unit is connected to the end of the flipping shaft.

[0014] Preferably, the rotary drive unit is a rotary cylinder, a servo motor, or a rotary electric cylinder.

[0015] Preferably, the linear drive is a linear motor or a rodless cylinder, and the connecting plate is mounted on the moving block of the linear motor or rodless cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The nest box transfer device, by setting up a flipping component, a connecting frame and a clamping component, drives the clamping component to rotate 90° and hide below the direction of nest box movement after the nest box body is transferred to the conveyor belt. This eliminates the physical obstruction of the transfer device above the nest box, ensuring that the efficient and clean airflow directly blows the surface of the nest box body and avoids the nest box body being blocked during the blowing.

[0018] 2. The nest box transfer device conceals the flipped clamping box assembly between the side plates on both sides of the conveyor belt, and maintains a safe gap with the bottom of the nest box body to avoid contact with the nest box body during the transfer process and prevent the nest box body from being contaminated.

[0019] 3. This nest box transfer device, by combining a cam track plate and a cam follower, converts the Y-axis motion of the linear drive into the rotational motion of the flipping shaft, solving the problems of complex multi-drive structures and large space occupation in the existing technology, while reducing maintenance costs.

[0020] 4. This nest box transfer device simplifies the transmission process and improves the structural compactness by directly driving the flipping shaft with a rotary drive unit. It solves the problem of difficult equipment layout caused by bulky mechanisms. While ensuring contactless transfer and unobstructed airflow, the entire device is highly integrated into the space below the conveyor belt, solving the problems of large equipment size and low cleanroom space utilization in existing technologies.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 2-6 A nest box transfer device includes: a connecting frame 4, a linear drive 2 mounted on a workbench 1, and a clamping assembly 3 for holding the nest box body 9; a flipping assembly 5, which is mounted on a moving block of the linear drive 2; the connecting frame 4 is mounted on the flipping assembly 5; the clamping assembly 3 is mounted on the connecting frame 4; one end of the flipping assembly 5 is connected to a flipping element 6; the flipping element 6 drives the clamping assembly 3 to flip 90°; after the clamping assembly 3 completes the transfer of the nest box body 9 to the conveyor belt 7 on the workbench 1, the flipping element 6 drives the flipping assembly 5 and the clamping assembly 3 to flip to... Below the direction of movement of the nest box body 9, the clamping assembly 3 forms a safe gap with the bottom of the nest box body 9. After the nest box body is transferred to the conveyor belt 7, the clamping assembly 3 is driven to rotate 90° and hide below the direction of movement of the nest box, eliminating the physical obstruction of the transfer device on the top of the nest box, ensuring that the efficient and clean airflow directly blows the surface of the nest box body, and avoiding obstruction of the blowing of the nest box body. After being flipped, the clamping assembly 3 is completely hidden between the side plates on both sides of the conveyor belt 7, and maintains a safe gap with the bottom of the nest box body, avoiding contact with the nest box body during the transfer process and preventing the nest box body from being contaminated.

[0030] Please see Figure 2-5 The clamping box assembly 3 includes a fixing plate 31 and a clamping cylinder 32. The fixing plate 31 is installed on the top of the connecting frame 4, and the clamping cylinder 32 is installed on the top of the fixing plate 31. A first clamping plate 33 is connected to the side of the fixing plate 31, and a second clamping plate 34 is installed at the telescopic end of the clamping cylinder 32. The surface of the first clamping plate 33 is connected to the surface of the second clamping plate 34.

[0031] Please see Figure 4-6 The flipping assembly 5 includes a flipping shaft 51, a connecting plate 52 is mounted on the moving block of the linear drive 2, a bearing seat 53 is symmetrically arranged on the top of the connecting plate 52, the surface of the flipping shaft 51 is connected to the inner wall of the bearing seat 53, a connecting frame 54 is mounted on the surface of the flipping shaft 51, and the connecting frame 4 is mounted on the surface of the connecting frame 54.

[0032] Please see Figure 4-5 In one specific embodiment, the flipping component 6 consists of two parallel cam track plates 61, which are mounted on the worktable 1. Cam followers 10 are mounted at both ends of the flipping shaft 51, and mounting plates 8 are mounted at both ends of the flipping shaft 51. Cam followers 10 are mounted on the surface of the mounting plates 8 and connected to the track grooves of the cam track plates 61. When the linear drive component moves the flipping shaft 51 along the Y direction, the cam followers 10 move along the track grooves and drive the flipping shaft 51 to rotate. The combination of the cam track plates 61 and the cam followers converts the Y-direction motion of the linear drive component 2 into the rotational motion of the flipping shaft 51, solving the problems of complex multi-drive structures and large space occupation in the prior art, while reducing maintenance costs.

[0033] Please see Figure 6 In one specific embodiment, the flipping component 6 is a rotary drive unit 601, which is mounted on the moving block of the linear drive component 2. The output shaft of the rotary drive unit 601 is connected to the end of the flipping shaft 51. The rotary drive unit 601 is a rotary cylinder, servo motor, or rotary electric cylinder. The rotary drive unit 601 directly drives the flipping shaft 51, which simplifies the transmission process and improves the structural compactness. It solves the problem of difficult equipment layout caused by bulky mechanism. On the basis of ensuring contactless transfer and unobstructed airflow, the whole is highly integrated into the space below the conveyor belt 7, which solves the problems of large equipment size and low cleanroom space utilization in the prior art.

[0034] In one specific embodiment, the linear drive 2 is a linear motor or a rodless cylinder, and the connecting plate 52 is mounted on the moving block of the linear motor or rodless cylinder.

[0035] In use, the clamping box assembly 3 is in the initial position, and the Z-axis clamping cylinder 32 opens; the upstream nest box body is transported to the initial position for positioning, the clamping cylinder 32 of the clamping box assembly 3 is activated, and the telescopic end of the clamping cylinder 32 drives the second clamping plate 34 to move, and the first clamping plate 33 and the second clamping plate 34 clamp the edge of the nest box body.

[0036] The linear drive 2 moves, which in turn drives the connecting plate 52 to move. The connecting plate 52 drives the flipping assembly 5 to move. The flipping assembly 5 drives the clamping box assembly 3 to move along the Y direction through the connecting frame 4, pulling the nest box body out of the outer bag and transferring it directly above the conveyor belt 7. After the nest box body completely covers the conveyor belt 7, the clamping cylinder 32 opens to release the nest box and flips it over to hide it.

[0037] In one specific embodiment, the linear drive 2 continues to move in the Y direction, and the flip shaft 51 drives the cam followers at both ends to move along the track groove of the cam track plate 61 through the mounting plate, driving the flip shaft 51 to rotate 90°. The flip shaft 51 drives the connecting frame 54 to move, the connecting frame 54 drives the connecting frame 4 to move, and the connecting frame 4 drives the clamping box assembly 3 to flip to a horizontal state. By using the combination of the cam track plate 61 and the cam follower, the Y direction motion of the linear drive 105 is converted into the rotational motion of the flip shaft 51, eliminating the need for a separate rotational drive unit 601, solving the problem of complex multi-drive structure and large space occupation in the prior art, and reducing maintenance costs.

[0038] In one specific embodiment, the rotary drive unit 601 directly drives the flip shaft 51 to rotate 90°, causing the clamp box assembly 3 to flip to a horizontal state. The modular flip drive design uses the rotary drive unit 601 to directly drive the flip shaft 51, which simplifies the transmission chain and improves the structural compactness, solving the problem of difficult equipment layout caused by the bulky mechanism in the prior art.

[0039] In its final state, the clamping box assembly 3 is hidden below the direction of movement of the nest box body, between the side plates on both sides of the conveyor belt 7, and forms a safe gap with the bottom of the nest box.

[0040] During reset, the linear drive 2 moves in the opposite direction, and the clamping box assembly 3 moves in the Y direction. It is driven by the cam track plate 61101 to rotate 90° counterclockwise to reset, or driven by the rotary drive unit 601303 to rotate 90° counterclockwise to reset, returning to the initial position of the mouse hole. The clamping cylinder 32 opens to wait for the next nest box.

[0041] Through the aforementioned flip-and-hide structure integration, while ensuring contactless transfer and unobstructed airflow, the entire device is highly integrated into the space below the conveyor belt 7, solving the problems of large equipment size and low cleanroom space utilization in the prior art.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
