Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery and equipment, and in particular to a filling and capping system. Background Technology

[0002] In the pre-filled automatic filling and capping machine system, the pallet transfer system is used for transporting packaging materials for filling and capping. When the pre-filling needle is placed into the pallet, there is a large gap between it and the pallet. During the transfer process of the pallet transfer system, the bottles will shake and become inaccurately positioned. Therefore, in the subsequent filling and capping process, the filling needle and capping sleeve need to be well aligned with the bottle neck (clamping and fixing the bottle) to ensure the stability and quality of the filling and capping process.

[0003] Patent CN208868439U discloses a pre-filling and sealing system suitable for small-batch production. It features a simple and compact structure, low cost, and suitability for small-batch production. However, the trays used for bottle loading / unloading and filling / coring lack a corresponding bottle-clamping structure, making them prone to bottle slippage and affecting production efficiency. Therefore, during filling and coring, the pre-filling needles on the entire tray need to be clamped. During online weighing, the bottles need to be detached from the tray for weighing before entering the tray. Both detachment and entry require limiting the tray's position to ensure accurate positioning of the tray holes, facilitating robotic gripping and ensuring the stability of the weighing operation. Simultaneously, the bottles must be in a movable state for gripping, weighing, and entry into the tray. The same principle applies to loading / unloading: limiting the tray's position ensures accurate positioning of the tray holes, and the bottles must be in a movable state for the robotic arm to grip them more accurately.

[0004] Existing technology cannot solve the problem of clamping the pre-filling needles on the entire pallet during filling and plugging, and the need to limit the pallet during weighing and loading / unloading, while keeping the pre-filling needles in an active state to facilitate accurate picking and placing of the pre-filling needles by the robot arm. Summary of the Invention

[0005] The purpose of this invention is to provide a filling and plugging system that solves the problem of clamping the pre-filling needles on the entire pallet during filling and plugging, and limiting the pallet during weighing and loading / unloading, while keeping the pre-filling needles in an active state to facilitate accurate picking and placing of the pre-filling needles by a robotic arm.

[0006] This invention is implemented as follows: a filling and capping system includes a track for conveying nest boxes, a filling and capping station and a weighing station arranged along the track, and a tray for transferring nest boxes between the filling and capping station and the weighing station. The tray includes an upper plate, a lower plate and a movable plate disposed between the upper plate and the lower plate, and both the upper plate and the lower plate are provided with through holes for cylindrical containers to pass through.

[0007] The upper plate is provided with a first limiting part and a second limiting part for limiting the nest board on both sides along the moving direction of the movable plate. The first limiting part can move along the moving direction of the movable plate. The upper plate is provided with a third limiting part for limiting the nest board on both sides of the moving direction of the movable plate.

[0008] A further technical solution of the present invention is: the first limiting part and the second limiting part are respectively placed at both ends of the moving direction of the movable plate for limiting. The first limiting part is movable and the second limiting part is fixed. When the movable plate drives the columnar container to move, the first limiting part will move together with the movable plate, and the nest plate moves along the third limiting part during the movement, so that the nest plate will not be deviated during the movement.

[0009] The movable plate moves towards the filling and stoppering station and stops after reaching the set position. In this state, the cylindrical container is clamped. During the movement, the nest plate moves along the third limiting part without shifting, and the positioning of the nest plate hole is accurate. When the movable plate drives the cylindrical container to move towards the weighing station, the cylindrical container is in a movable state. During the movement, the nest plate moves along the third limiting part without shifting. The nest plate is limited by the action of the second limiting part and the first limiting part. At this time, the positioning of the nest plate hole is accurate.

[0010] During the movement of the pallet towards the filling and capping station and the weighing station, the pallet can be accurately positioned, ensuring that the cylindrical containers do not shake during transfer while clamped. It has high stability and accuracy during the filling and capping process, and ensures that the position of the pallet is accurate while the cylindrical containers are in motion, which facilitates the loading and unloading of the robot and the weighing of the cylindrical containers. Thus, during filling and capping, the cylindrical containers on the entire pallet are clamped, and during weighing and loading / unloading, the pallet can be limited, while the cylindrical containers are in a movable state, which facilitates the robot to accurately pick up and place the cylindrical containers.

[0011] The movable plate is an integral structure. When the movable plate moves to both sides, it can clamp or move an entire tray of packaging materials, which is convenient and quick.

[0012] A further technical solution of the present invention is that the second limiting part is an L-shaped limiting member, and the second limiting part cooperates with the corner of the nest plate away from the first limiting part.

[0013] The L-shaped limiting component, located at the corner, not only limits the nest board in the direction of movement but also limits it on both sides of the nest board's direction of movement to prevent deviation.

[0014] A further technical solution of the present invention is that the third limiting part is elongated.

[0015] The elongated third limiting part plays a guiding and limiting role during the movement of the nest board, preventing the nest board from shifting during the movement.

[0016] A further technical solution of the present invention is: the cylindrical container passes through the tray, and when the movable plate moves to the weighing station side, the cylindrical container and the tray are in clearance fit; when the clamping plate moves to the filling and plugging station side, the outer periphery of the cylindrical container is tightly fitted to the tray.

[0017] A further technical solution of the present invention is as follows: the movable plate has a plate-like structure and is provided with honeycomb holes, and the columnar container passes through the honeycomb holes on the movable plate; after the columnar container passes through the tray, the movable plate moves to the weighing platform side, and with the cooperation of the first limiting part and the second limiting part, the columnar container is fitted with the tray with a gap. When the movable plate moves to the filling and plugging side, the columnar container is fixed under the pressure of the upper plate, the lower plate and the inner wall of the movable plate.

[0018] A further technical solution of the present invention is as follows: the movable plate includes multiple connecting plates, and gaps are provided between the connecting plates, through which the columnar container passes; the extending direction of the connecting plates is perpendicular to the moving direction of the movable plate; when the movable plate moves toward the weighing station, under the cooperation of the first limiting part and the second limiting part, the columnar container is clearance-fitted with the through holes of the upper plate and the lower plate and the gap between the connecting plates, at which time the columnar container can move, and the nest plate is also limited; when the movable plate moves toward the filling and plugging side, the columnar container is fixed under the compression of the upper plate, the lower plate and the outer periphery of the movable plate, at which time the columnar container is fixed, and the nest plate is also limited.

[0019] A further technical solution of the present invention is: a limiting groove is provided on the upper plate, the first limiting part passes through the limiting groove and is connected to the movable plate, and the first limiting part is slidably connected to the limiting groove.

[0020] The sliding distance of the first limiting part in the limiting groove is matched with the positioning of the nest plate, so that the nest plate can be adapted to the position of the robot arm when it moves to both sides, ensuring the accurate gripping of the robot arm, thereby achieving accurate loading and unloading and weighing; at the same time, it facilitates the accuracy of filling and plugging.

[0021] A further technical solution of the present invention is that the tray further includes a driving structure, the output end of which is connected to the first limiting part.

[0022] A further technical solution of the present invention is that the driving structure is a cam connecting rod structure, a drive motor, or a cylinder.

[0023] A further technical solution of the present invention is: the lower plate is provided with an opening, and the output end of the drive structure passes through the opening and is connected to the movable plate.

[0024] A further technical solution of the present invention is that a buffer layer is provided on the contact surface between the movable plate and the columnar container.

[0025] The buffer layer can compensate for the processing errors of multiple complex honeycomb holes and the dimensional errors of the cylindrical container itself by deforming when it comes into contact with the cylindrical container. This avoids the situation where some cylindrical containers are not clamped, ensures the accurate positioning of the cylindrical containers, and facilitates subsequent filling, plugging, loading and unloading, and weighing.

[0026] A further technical solution of the present invention is that the buffer layer is a rubber strip.

[0027] The beneficial effects of this invention are as follows: When the movable plate moves toward the filling and plugging station, it clamps the cylindrical containers on the pallet, facilitating filling, plugging, and transportation; when the movable plate moves toward the weighing station, the cylindrical containers are in a movable state, allowing for smooth loading and unloading of the cylindrical containers during weighing and material handling; during the movement of the movable plate to both sides, the pallet remains within the third limiting part for limited movement, thus preventing the pallet from shifting during movement and facilitating accurate loading and unloading of the cylindrical containers by the robotic arm.

[0028] The first and second limiting parts are respectively positioned at both ends of the moving plate in the direction of movement to limit movement. When the moving plate drives the cylindrical container to move to both sides, the first limiting part moves along with the moving plate. During the movement, it moves along the third limiting part without deviation. The first limiting part drives the moving plate to move towards the filling and capping station, and stops after reaching the set position. In this state, the cylindrical container is clamped and will not shake during transfer. Furthermore, the nesting plate moves along the third limiting part without deviation during the movement, ensuring accurate positioning of the nesting plate holes and maintaining stability and accuracy during the filling and capping process. High; When the movable plate moves the cylindrical container to the weighing station, the cylindrical container is in an active state, which facilitates the loading and unloading of the robot. During the movement, the nest plate moves along the third limiting part without shifting. The nest plate is limited by the second limiting part and the first limiting part. At this time, the positioning of the nest plate hole is accurate, which facilitates the loading and unloading of the robot and the weighing of the cylindrical container. Thus, when filling and plugging, the cylindrical container on the whole nest plate is clamped, and when weighing and loading and unloading, the nest plate can be limited. At the same time, the cylindrical container is in an active state, which facilitates the robot to accurately pick up and put down the cylindrical container.

[0029] The buffer layer can compensate for the processing errors of multiple complex honeycomb holes and the dimensional errors of the cylindrical container itself by deforming when it comes into contact with the cylindrical container. This avoids the situation where some cylindrical containers are not clamped, ensures the accurate positioning of the cylindrical containers, and facilitates subsequent filling, plugging, loading and unloading, and weighing.

[0040] Example 1:

[0041] Figure 1-7 A filling and capping system is shown, including a track 10 for conveying nest boxes, a filling and capping station 12 and a weighing station 13 arranged along the track 10, and a nest box plate 5 transferred between the filling and capping station 12 and the weighing station 13 via a pallet. The pallet includes an upper plate 1, a lower plate 11, and a movable plate 2 disposed between the upper plate 1 and the lower plate 11. Both the upper plate 1 and the lower plate 11 are provided with through holes for cylindrical containers to pass through.

[0042] The upper plate 1 is provided with a first limiting part 3 and a second limiting part 41 for limiting the two sides of the nest plate 5 along the moving direction of the movable plate 2. The first limiting part 3 can move along the moving direction of the movable plate 2. The upper plate 1 is provided with a third limiting part 42 for limiting the nest plate 5 on both sides of the moving direction of the movable plate 2.

[0043] In this embodiment, the cylindrical container is a pre-filled needle.

[0044] In this embodiment, the first limiting part and the second limiting part are respectively placed at both ends of the moving direction of the movable plate to limit the movement. The first limiting part is movable and the second limiting part is fixed. When the movable plate drives the pre-filling needle to move, the first limiting part will move with the movable plate. During the movement, the nest plate moves along the third limiting part, so that the nest plate will not be deviated during the movement.

[0045] The nest box is transported to the weighing station via a track. The first robotic arm removes the nest board with pre-filled needles from the nest box and places it on a tray. The second robotic arm removes a row of pre-filled needles and places them on the weighing station for initial weighing. At this time, the movable plate is in its initial state, that is, the movable plate does not clamp the pre-filled needles. The first, second, and third limiting parts limit the nest board to ensure that the pre-filled needles are aligned with the center of the holes in the nest board when they are put back, so that the pre-filled needles that have been weighed can be put back into the nest board.

[0046] After the initial weighing, the pallet moves towards the filling and capping station. During this movement, the movable plate and the first limiting part also move until the pallet reaches the filling and capping station, where the pre-filling needles placed on the pallet are filled. At this time, the movable plate is in a moving state, clamping the pre-filling needles to ensure they do not wobble during filling. Because clamping the pre-filling needles in this state would cause the nesting board to shift in the direction of the movable plate's movement, the first limiting part is designed to move with the movable plate without affecting the nesting board's displacement.

[0047] After filling is completed, the pallet moves to the weighing station for a second weighing to ensure filling accuracy. When the pallet reaches the weighing station, the movable plate is in its initial state, i.e., the movable plate does not clamp the pre-filled needles. The second robotic arm removes a row of pre-filled needles and places them on the weighing station for a second weighing. At this time, the first limiting part returns to its original position to limit the nesting board. This is because when the pre-filled needles are clamped, the nesting board will shift to one side. During the process of the pre-filled needles going from being clamped to not being clamped, there is a gap between the pre-filled needles and the nesting board, and the nesting board is not completely reset. At this time, the first limiting part is needed to make the nesting board completely reset. If the first limiting part does not return to its original position, there will be a situation where the pre-filled needles are removed for weighing and then put back on the nesting board, and the center of the holes in the nesting board cannot be aligned, causing the pre-filled needles to collide with the nesting board.

[0048] After the second weighing, the pallet moves to the filling and plugging station for plugging. At this time, the state of the movable plate and the first limiting part is the same as during filling.

[0049] After the insertion is completed, the pallet moves to the weighing station again, and the first robotic arm takes out the nest board and puts it into the nest box. The nest box moves to the next station along the track.

[0050] The movable plate moves towards the filling and stoppering station and stops after reaching the set position. In this state, the pre-filling needle is clamped. During the movement, the nesting plate moves along the third limiting part without deviation, and the positioning of the nesting plate hole is accurate. When the movable plate drives the pre-filling needle to move towards the weighing station, the pre-filling needle is in an active state. During the movement, the nesting plate moves along the third limiting part without deviation. The nesting plate is limited by the action of the second limiting part and the first limiting part. At this time, the positioning of the nesting plate hole is accurate.

[0051] During the movement of the movable plate to the filling and capping station and the weighing station, the pallet can be accurately positioned, ensuring that the pre-filled needles do not shake during transfer while in a clamped state. It has high stability and accuracy during the filling and capping process, and ensures that the position of the pallet is accurate when the pre-filled needles are in the movable state, which facilitates the loading and unloading of the robot and the weighing of the pre-filled needles. Thus, during filling and capping, the pre-filled needles on the entire pallet are clamped, and during weighing and loading and unloading, the pallet can be limited, while the pre-filled needles are in a movable state, which facilitates the robot to accurately pick up and put down the pre-filled needles.

[0052] In this embodiment, the movable plate is an integral structure. When the movable plate moves to both sides, it can clamp an entire tray of pre-filled needles, which is convenient and quick.

[0053] In this embodiment, the second limiting part 41 is an L-shaped limiting member, and the second limiting part 41 cooperates with the corner of the nest plate 5 on the side away from the first limiting part 3.

[0054] The L-shaped limiting component, located at the corner, not only limits the nest board in the direction of movement but also limits it on both sides of the nest board's direction of movement to prevent deviation.

[0055] In this embodiment, the third limiting part 42 is elongated.

[0056] The elongated third limiting part plays a guiding and limiting role during the movement of the nest board, preventing the nest board from shifting during the movement.

[0057] In this embodiment, the cylindrical container passes through the tray. When the movable plate 2 moves toward the filling and plugging station, the cylindrical container and the tray are in clearance fit. When the clamping plate 2 moves toward the weighing station, the outer periphery of the cylindrical container is tightly fitted to the tray.

[0058] In this embodiment, the movable plate has a plate-like structure with honeycomb holes, and the columnar container passes through the honeycomb holes on the movable plate. After the columnar container passes through the tray, the movable plate moves towards the weighing station. With the cooperation of the first limiting part and the second limiting part, the columnar container is fitted with the tray with a gap. When the movable plate moves towards the filling and plugging station, the columnar container is fixed under the pressure of the upper plate, the lower plate and the inner wall of the movable plate.

[0059] In a preferred embodiment, the movable plate includes multiple connecting plates with gaps between them, through which the cylindrical container passes. The extending direction of the connecting plates is perpendicular to the moving direction of the movable plate. When the movable plate moves toward the weighing station, the first and second limiting parts cooperate to allow the cylindrical container to engage with the through holes of the upper and lower plates and the gaps between the connecting plates. At this time, the cylindrical container is movable, while the nesting plate is also limited. When the movable plate moves toward the filling and plugging station, the cylindrical container is fixed by the compression of the upper plate, lower plate, and the outer periphery of the movable plate. At this time, the cylindrical container is fixed, while the nesting plate is also limited.

[0060] In this embodiment, the upper plate 1 is provided with a limiting groove, the first limiting part 3 passes through the limiting groove and is connected to the movable plate 2, and the first limiting part 3 is slidably connected to the limiting groove.

[0061] The sliding distance of the first limiting part in the limiting groove is matched with the positioning of the nest plate, so that the nest plate can be adapted to the position of the robot arm when it moves to both sides, ensuring the accurate gripping of the robot arm, thereby achieving accurate loading and unloading and weighing; at the same time, it facilitates the accuracy of filling and plugging.

[0062] In this embodiment, the tray further includes a drive structure 6, the output end of which is connected to the first limiting part 3.

[0063] In this embodiment, the drive structure 6 is a cam-linkage structure, a drive motor, or a cylinder.

[0064] In this embodiment, the lower plate 11 has an opening, and the output end of the drive structure 6 passes through the opening and is connected to the movable plate 2.

[0065] In this embodiment, a buffer layer is provided on the contact surface between the movable plate 2 and the columnar container.

[0066] The buffer layer can compensate for the processing errors of multiple complex honeycomb holes and the dimensional errors of the cylindrical container itself by deforming when it comes into contact with the cylindrical container. This avoids the situation where some cylindrical containers are not clamped, ensures the accurate positioning of the cylindrical containers, and facilitates subsequent filling, plugging, loading and unloading, and weighing.

[0067] In this embodiment, the buffer layer is an adhesive strip.

[0068] The working principle of this invention: When the driving structure 6 moves the movable plate 3 towards the side closer to the second limiting part 41, it moves to a position where it is limited by the second limiting part 41. At this time, as... Figure 3 The image shows the tray in the open state. The center of the honeycomb holes on the movable plate 2 is concentric with the through holes on the upper plate 1 and the lower plate 11, allowing the cylindrical container (pre-filled needle) to be inserted and removed, realizing the functions of feeding, discharging, and removing / removing the honeycomb. After the cylindrical container (pre-filled needle) is placed on the tray, the packaging material is transported to the subsequent filling and capping station by the tray transfer station, and the tray switches to... Figure 4 The tray is shown in the clamped state. At this time, the movable plate 2 moves, moving the cylindrical container (pre-filling needle) closer to the first limiting part 3. The first limiting part 3 can move, allowing the cylindrical container (pre-filling needle) to be pushed against the upper plate 1, lower plate 11, and movable plate 2. At this time, each bottle is firmly clamped by the three layers of plates. After the cylindrical container (pre-filling needle) is clamped, it will not shake during the subsequent tray transfer process. The high-precision honeycomb holes processed by the tray accurately position the bottle mouth of the cylindrical container (pre-filling needle), which can effectively ensure the accuracy and stability of the subsequent filling and capping process. The contact point between the movable plate 2 and the cylindrical container (pre-filling needle) is equipped with a buffer layer. When they are clamped, the deformation of the soft buffer layer can compensate for the processing error zone of multiple complex honeycomb holes and the dimensional error of the cylindrical container (pre-filling needle) itself, avoiding the situation where some cylindrical containers (pre-filling needles) are not clamped.

[0069] The first limiting part 3 moves together with the movable plate 2; in the unclamped state, such as Figure 3The first limiting part 3, the second limiting part 41, and the third limiting part 42 shown limit and fix the honeycomb plate 5. At this time, the position of the honeycomb plate 5 on the tray is accurate, and the honeycomb holes on the honeycomb plate and the movable plate 2 are accurately positioned, allowing for stable feeding, unloading, and honeycomb removal and insertion. When switching to the clamping state, the movable plate 2 moves in the direction of the arrow, from Figure 2 and 3 Switching to Figure 3 and 4 In the current state, during the clamping action, the movable plate 2 pushes the cylindrical container (pre-filling needle) in the direction of movement. This means the cylindrical container (pre-filling needle) needs to move in the direction of the arrow. To avoid interfering with the clamping action, the first limiting part 3 moves in the direction of the arrow along with the movable plate 2, making room for the movement of the nesting plate 5. When switching back to the non-clamping state, the first limiting part 3 moves back along with the movable plate 2, pushing the nesting plate 5 back to the second limiting part 41, thus fixing and limiting the nesting plate 5.

[0070] During the transfer process, the movement of the movable plate 2 is driven in two ways: one is... Figure 6 As shown, the baffle curve on the pallet transfer station drives the linkage mechanism, pushing the movable plate 2 to move, with a spring providing the return force; another method is... Figure 7 The movable plate 2 is driven to move by a pneumatic or electric component.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
