Description

Technical Field

[0001] The present application relates to the technical field of pharmaceutical equipment waste treatment, and in particular to a liner paper directional discharge device and an isolator. Background Art

[0002] In the biopharmaceutical industry, numerous production and experimental processes must be conducted in strictly controlled isolated environments, such as sterile isolators, restricted access barrier systems (RABS), or high-class cleanrooms. Core technical requirements for these isolated environments are precisely maintaining preset air cleanliness levels, positive pressure differentials, or specific gas compositions to ensure process stability, product sterility, and operator safety. This process inevitably generates solid waste, such as packaging liner paper, film, and process scraps.

[0003] Currently, a common way to handle waste materials within a controlled environment is to directly drop the waste materials downward into an external collection container through an opening or channel set on the outer wall of the environment. This method is simple and intuitive, but it has significant drawbacks in situations where high isolation performance must be maintained, such as isolators that maintain positive pressure or sterility: First, to facilitate the rapid passage of waste materials, the disposal opening is typically designed to be large. When the controlled environment maintains positive pressure, such a large opening causes a large amount of internal gas to continuously leak out, making it difficult to maintain the required pressure differential, resulting in energy waste and even causing loss of control over internal pressure or gas composition. Conversely, if external pressure fluctuates or airflow is disturbed, unclean air, pollutants, or moisture can easily flow back into the internal environment through the opening, seriously compromising the internal cleanliness or sterility, resulting in the scrapping of the entire process or product batch, resulting in significant losses.

[0004] Secondly, for flexible and easily curled waste materials such as liner paper and film, simply discarding them downward can easily cause them to become stuck, folded, or tangled as they pass through the opening, preventing smooth discharge. This material jamming not only affects discharge efficiency but can also further increase the time or area of ​​the opening exposed, exacerbating the risk of environmental isolation failure as mentioned above. It can even completely block the discharge channel, causing equipment downtime or requiring complex and potentially disruptive interventions for cleanup. Summary of the Invention

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0024] See also Figures 1 to 5 , an embodiment of the present application provides a liner paper directional discharge device 100 and an isolator including the liner paper directional discharge device 100 .

[0025] like Figure 3 As shown, the isolator includes a main body 200, an isolation environment that needs to maintain a preset positive pressure is formed inside the main body 200, and a discharge outlet 201 is provided on the wall of the main body 200. The isolator also includes a gripping mechanism (not shown) and a paper discharge device arranged inside the main body 200, that is, the liner paper directional discharge device 100 provided in this embodiment. The gripping mechanism is used to grab the waste liner paper generated in the isolation environment and place it on the liner paper directional discharge device 100. In specific implementation, the liner paper directional discharge device 100 is installed on the main body 200 and cooperates with the discharge outlet 201. The gripping mechanism can adopt a combination of a robotic arm and a clamp, and the clamp is used to clamp a corner or one side edge of the waste liner paper and transfer it to the liner paper directional discharge device 100 using a robotic arm to discharge the liner paper to the outside of the isolator. Active and directional discharge of liner paper waste inside the isolation environment is achieved with minimal disturbance to the isolation environment.

[0026] The following will be combined with the Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 , the specific structure of the liner paper directional discharge device 100 is described in detail.

[0027] Specifically, if Figure 1 As shown, the liner paper directional discharge device 100 includes a conveying platform 10 , a pushing mechanism 20 and a closing guide assembly 30 .

[0028] The conveying platform 10 is disposed within the separator body 200 and includes a first end 10a and a second end 10b disposed opposite each other. The first end 10a serves as a support end for supporting the liner paper to be discharged, which is placed by the gripping mechanism. In this embodiment, the first end 10a is preferably located near the gripping mechanism's operating range to simplify its movement path.

[0029] The pushing mechanism 20 is also disposed within the main body 200 and is configured to apply a horizontal thrust from the first end 10a toward the second end 10b to the liner paper supported on the conveying platform 10, thereby enabling active and controllable conveyance of the liner paper along a predetermined path. This avoids the uncertainty associated with prior art techniques that rely solely on the liner paper's gravity. The specific structure of the pushing mechanism 20 will be further described in subsequent embodiments.

[0030] like Figure 1 、 Figure 3 As shown, the closing guide assembly 30 is installed at the discharge port 201 of the isolator body 200 to guide the liner and protect the isolation environment. In this embodiment, the closing guide assembly 30 includes a partition 31 and a discharge channel 32.

[0031] The partition 31 is provided at the discharge port 201 to seal the larger discharge port 201. The partition 31 is provided with a waste paper outlet 33 having a smaller diameter than the discharge port 201. This significantly reduces the area of ​​the passage through which the liner paper is discharged, thereby effectively reducing gas exchange between the internal and external environments of the isolator without affecting the discharge of the liner paper. This effectively maintains the positive pressure stability within the isolation environment and prevents the intrusion of external contaminants.

[0032] Specifically, the front opening of the discharge channel 32 communicates with the waste paper outlet 33, while the rear opening of the discharge channel 32 is flared to form a guide inlet for receiving liner paper. This flared structure allows the liner paper to be gathered and corrected as it is pushed, ensuring that even easily curled liner paper can be smoothly aligned and enter the smaller waste paper outlet 33. To ensure continuous conveying, the second end 10b of the conveying platform 10 extends into the rear flared opening of the discharge channel 32. Finally, the pushing mechanism 20 pushes the liner paper along the conveying platform 10, and guided by the discharge channel 32, it passes through the waste paper outlet 33 and is discharged outside the separator.

[0033] In some embodiments, as Figure 4As shown, the closing guide assembly 30 also includes a door panel 34, the top edge of which is pivotally connected to the partition 31. The door panel 34 is configured to cover the waste paper outlet 33 when no external force is applied, and the door panel 34 is normally closed. When the liner paper is pushed into the waste paper outlet 33, the thrust cooperates with the positive pressure airflow within the isolation environment to push the door panel 34 outward, allowing the liner paper to be discharged. In addition, the door panel 34 is provided with a plurality of vent holes 341 connected to the interior of the discharge channel 32 to promptly release excess pressure and maintain a stable pressure within the isolator.

[0034] In some embodiments, as Figure 1 、 Figure 5 As shown, the discharge channel 32 includes a guide plate 321 and support plates 322 disposed on either side of the guide plate 321. The front edge of the guide plate 321 is tilted forward relative to the surface of the conveying platform 10, and the two support plates 322 are removably mounted on the conveying platform 10. With this structural design, the discharge channel 32 is open at the bottom. The guide plate 321 forms the top surface of the discharge channel 32, while the two support plates 322 are vertically fixed to the conveying platform 10 and form the side walls of the discharge channel 32. The guide plates 321, support plates 322, and the surface of the conveying platform 10 collectively define a channel for the discharge of waste liner paper. The front edge of the guide plate 321 faces the waste paper outlet 33 and is connected to the top edge of the waste paper outlet 33, ensuring that any curled liner paper is guided into the waste paper outlet 33. The support plates 322, connected to the left and right edges of the waste paper outlet 33, provide lateral positioning and guidance for the liner paper, preventing it from drifting.

[0035] In a specific embodiment, if Figure 4 、 Figure 5 As shown, the bottom edges of the two support plates 322 are each provided with a downward-opening positioning notch 3221; the conveying platform 10 is provided with a protruding locking stud (not shown) at the position corresponding to the positioning notch 3221, and the locking studs extend into the corresponding positioning notches 3221. During installation, the operator only needs to align the positioning notches 3221 of the support plate 322 and insert the locking studs to achieve quick and accurate initial positioning. The locking studs are connected to the support plate 322 by a hand-tightening nut 40 to achieve a detachable connection between the support plate 322 and the conveying platform 10. When the equipment needs to be cleaned, sterilized or repaired, the operator can quickly remove the support plate 322 together with the guide plate 321, so that the entire table surface of the conveying platform 10 and all inner surfaces of the discharge channel 32 are completely exposed, easy to wipe and handle, and without sanitary dead corners.

[0036] In some embodiments, as Figure 4 、 Figure 5As shown, the bottom side edges of both of the support plates 322 are provided with outwardly bent skirt edges 3222. The provision of the skirt edges 3222 serves to increase the bending resistance of the entire discharge channel 32, and, on the other hand, the outward bending of the skirt edges 3222 relative to the support plates 322 causes the bottom opening of the discharge channel 32 to have a flared shape, thereby providing assembly guidance when assembling the entire discharge channel 32.

[0037] In some embodiments, as shown in Figure 5 As shown, the discharge channel 32 further comprises an ear plate 35 which is arranged parallel to the partition plate 31 and connected to the guide plates 321 and the support plates 322 on the side away from the partition plate 31. Specifically, the ear plate 35 is a substantially vertically arranged plate member which, by connecting the guide plates 321 and the support plates 322, further improves the structural strength of the entire discharge channel 32.

[0038] In some embodiments, as shown in Figure 1 、 Figure 4 、 Figure 5 As shown, the ear plate 35 and / or the guide plates 321 are provided with a lifting member 36. In specific implementation, the lifting member 36 can be a robust rod-shaped or strip-shaped structure, for example, a handle formed by bending a metal rod. The lifting member 36 can be provided on the ear plate 35 or the guide plates 321 alone, or on both the ear plate 35 and the guide plates 321. In addition, the end of the lifting member 36 away from the ear plate 35 is connected to the partition plate 31, thereby integrating the entire detachable discharge channel 32, i.e., the unit composed of the partition plate 31, the guide plates 321, the support plates 322, the ear plate 35 and the lifting member 36, into a whole, which is convenient for lifting and moving away from the conveying platform 10.

[0039] In some embodiments, as shown in Figure 1 、 Figure 2 As shown, the conveying platform 10 comprises a rack 13 as the structural basis and a table body 11 arranged on the rack 13. The table body 11 is installed on the rack 13, and its flat upper surface constitutes the main load-carrying surface on which the backing paper is slid and conveyed. In order to ensure that the backing paper always moves along the predetermined path during the conveying process without lateral deviation or falling, the table body 11 is provided with side plates 12 extending from the first end 10a to the second end 10b on the left and right sides thereof, and the side plates 12 and one end of the table body 11 both extend into the discharge channel 32. In this way, the load-carrying surface of the table body 11 and the side plates 12 on both sides jointly enclose a clear conveying channel having a U-shaped cross section. This channel provides continuous lateral constraint for the backing paper, ensuring the stability of its straight-line conveying. In this embodiment, locking studs are provided on the outer side walls of the two side plates 12.

[0040] In some embodiments, asFigure 2 As shown, the pushing mechanism 20 includes a linear driving mechanism 21 arranged on the frame 13 and a pawl 22 directly contacting the backing paper and applying a pushing force. The pawl 22 is slidingly mounted on the frame 13 and is configured to move from the first end 10a to the second end 10b under the driving of the linear driving mechanism 21. In the embodiment, as shown, the linear driving mechanism 21 can include a motor 211 as the power source of the entire mechanism, a synchronous belt 212 driven by the motor 211, a guide rod 213 parallel to the conveying direction, and a sliding table 214 that can smoothly slide on the guide rod 213, the sliding table 214 being firmly connected to the belt through a clamp. In this way, when the motor 211 drives the synchronous belt 212 to rotate, the sliding table 214 will perform a reciprocating linear motion along the guide rod 213, thereby driving the pawl 22 to realize the pushing stroke from the first end 10a to the second end 10b. Figure 2 Figure 2 As shown, the linear driving mechanism 21 can include a motor 211 as the power source of the entire mechanism, a synchronous belt 212 driven by the motor 211, a guide rod 213 parallel to the conveying direction, and a sliding table 214 that can smoothly slide on the guide rod 213, the sliding table 214 being firmly connected to the belt through a clamp. In this way, when the motor 211 drives the synchronous belt 212 to rotate, the sliding table 214 will perform a reciprocating linear motion along the guide rod 213, thereby driving the pawl 22 to realize the pushing stroke from the first end 10a to the second end 10b.

[0041] A guide groove 111 adapted to the moving path of the pawl 22 is formed on the tabletop of the table body 11, and a hook-shaped or block-shaped portion at the top end of the pawl 22 protrudes out of the tabletop of the table body 11 from the guide groove 111. In the embodiment, in order to ensure that a uniform and stable pushing force is applied to the light, thin and flexible backing paper and to avoid wrinkles or deviation caused by uneven force, a plurality of pawls 22 are preferably arranged in the embodiment. These pawls are equidistantly arranged on the sliding table 214 along the width direction of the table body 11 and collectively form a wide and uniform pushing front.

[0042] The end of the moving path of the pawl 22 is located at the portion of the table body 11 extending into the discharge channel 32. This means that the pushing stroke of the pawl 22 does not end at the entrance of the discharge channel 32, but continues for a certain distance, ensuring that the tail of the backing paper can also be completely and reliably fed into the discharge channel 32, avoiding the risk of stagnation or jamming of the backing paper at the entrance of the channel.

[0043] The backing paper directional discharge device and isolator provided by the embodiment of the present application actively push the backing paper through the setting of the pushing mechanism, and cooperates with the closing guiding assembly to directionally discharge the backing paper from a waste paper outlet with a controlled caliber, solving the problem of loss of control of the preset positive pressure environment in the isolator and invasion of external pollutants caused by the discharge of waste paper through a large opening in the prior art, and overcoming the possible jamming of the easily curled backing paper during the discharge process.
