Description

Technical Field

[0001] This utility model relates to the field of freeze-dried powder injection preparation technology, specifically a fixed automatic feeding and discharging system for freeze-dried formulation production lines. Background Technology

[0002] In the production process of freeze-dried powder injections, automated feeding and discharging systems are commonly used to achieve efficient transfer of vials inside and outside the freeze dryer. Existing technology typically employs a front-pushing device at the front of the freeze dryer and a rear-pushing device at the rear to collaboratively complete the vial feeding and discharging operations. Specifically, the front-pushing device pushes the vials into the freeze dryer using a push-pull rod equipped with a pusher plate; the rear-pushing device then pushes the vials out of the freeze dryer after freeze-drying. However, in practice, when the pusher plate of the rear-pushing device pushes out the freeze-dried product, the vials located at the very front (i.e., at the small door) lack a pusher plate for direct contact, resulting in a longer transmission path for the rear-pushing device, relying solely on the pushing force of the vials at the rear. This pushing method makes it difficult for the vials at the front to be transferred neatly to the vial sorting mesh bag, thus affecting the efficiency of transferring the vials from the sorting mesh bag to the discharge mesh bag, reducing the overall stability of the production line and product quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a fixed automatic feeding and discharging system for freeze-drying formulation lines. This system solves the problem that existing feeding and discharging systems, when pushing out vials, rely solely on the pushing force of the vials behind them to move them, resulting in the inability to neatly and orderly transfer the vials to the bottle-sorting mesh bag, thus affecting the efficiency of transferring the vials from the bottle-sorting mesh bag to the discharging mesh bag.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fixed automatic feeding and discharging system for a freeze-drying formulation line, comprising a freeze dryer, a small door on the front of the freeze dryer, an isolation chamber on the front side of the freeze dryer, and a feeding mesh bag, a bottle-sorting mesh bag, and a discharging mesh bag arranged sequentially along the length of the isolation chamber, the bottle-sorting mesh bag being located in front of the small door, and a feeding device on the outside of the isolation chamber, the feeding device including a push rod mechanism, the output end of which is provided with a bottle-sorting feeding push plate, the bottle-sorting feeding push plate being located on the front of the bottle-sorting mesh bag, pushing the vials on the bottle-sorting mesh bag into the small door; a discharging and pushing device is provided at the gap between the front side of the small door and the bottle-sorting mesh bag, the discharging and pushing device including a foldable bridging member that overlaps between the small door and the bottle-sorting mesh bag, the bridging member being provided with a bottle-sorting discharging push plate, pushing the vials in the small door onto the bottle-sorting mesh bag.

[0005] Preferably, the bridging component includes a bearing seat fixed to the front side of the small door, a transition flap rotatably connected to the bearing seat, and a flip push rod provided below the transition flap. When the transition flap flips, it can engage with the edge of the small door and the bottle sorting mesh bag. The bottle sorting discharge push plate is provided on the transition flap.

[0006] Preferably, the top of the transition flap is provided with an overlapping edge, which overlaps the small door when the transition flap is in a horizontal state.

[0007] Preferably, the transition flap is provided with side wall frames on both sides, and the side wall frames are provided with a first direction moving mechanism and a second direction moving mechanism; the first direction moving mechanism drives the bottle feeding push plate to move horizontally; the second direction moving mechanism drives the first direction moving mechanism and the bottle feeding push plate to move up and down; wherein, when the bottle feeding push plate rises to the highest point, a material passage gap is formed between the bottle feeding push plate and the transition flap, which allows vials to pass through.

[0008] Preferably, the second directional movement mechanism includes a vertical push rod fixed above the side wall frame, the output end of the vertical push rod is provided with a slider, and the first directional movement mechanism and the bottle unloading push plate are disposed on the slider.

[0009] Preferably, the first directional movement mechanism includes a horizontal push rod disposed on the slider, the output end of which passes through the slider and is fixed to the bottle discharge push plate.

[0010] Preferably, the height of the material passage gap is A, and the height of the bottle feeding pusher is B, wherein A > B.

[0011] Preferably, the width of the material passage gap is a, and the width of the bottle feeding pusher is b, wherein a > b.

[0012] Preferably, two bottle-feeding side plates are arranged parallel to each other on both sides of the upper surface of the transition flap.

[0013] The beneficial effects of this utility model are as follows: By using the fixed automatic feeding and discharging system for a freeze-drying formulation line provided by this utility model, compared with the prior art, a flip-up bridging component is set between the small door and the bottle-sorting mesh bag, and a liftable and pushable bottle-sorting discharge pusher is integrated on the bridging component. This achieves the connection or separation of the small door and the bottle-sorting mesh bag, avoiding the waste of idle space in the equipment and not interfering with the normal opening and closing of the small door and the feeding and pushing operation, thus significantly improving the space utilization rate. Through the bidirectional drive of the vertical pusher and the horizontal pusher, the bottle-sorting discharge pusher can stably separate the foremost vials into a single row and accurately push them onto the bottle-sorting mesh bag, so that the foremost vials no longer rely on the pusher from the rear, reducing the uncertainties in the transmission path, ensuring the smooth transfer of vials from the freeze dryer to the bottle-sorting mesh bag and then to the discharge mesh bag, and effectively preventing the vials from tilting, tipping, or being pushed inaccurately during the movement.

[0016] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] like Figures 1 to 8 As shown in the embodiment of this application, a fixed automatic feeding and discharging system for a freeze-drying formulation line is proposed, including a freeze dryer with a small door 1 on the front. An isolation chamber is located at the front of the freeze dryer, and within the isolation chamber, a feeding mesh bag, a bottle-sorting mesh bag 2, and a discharging mesh bag are arranged sequentially along its length. The feeding mesh bag, bottle-sorting mesh bag 2, and discharging mesh bag are conveyed in the same direction. In this configuration, the bottle-sorting mesh bag 2 is positioned directly in front of the small door 1.

[0020] A feeding device is provided on the outside of the isolation chamber. The feeding device includes a push rod mechanism 5. The output end of the push rod mechanism 5 passes through the isolation chamber, and the end inserted into the isolation chamber is provided with a bottle feeding push plate 3. The bottle feeding push plate 3 is located on the front of the bottle feeding mesh bag 2 and pushes the vials on the bottle feeding mesh bag 2 into the small door 1.

[0021] A push mechanism is provided at the rear of the freeze dryer to push the vials inside the freeze dryer to the small door 1. This push mechanism is existing technology and will not be described in detail here.

[0022] In addition, a discharge ejection device 4 is provided in the gap between the front side of the small door 1 and the bottle-sorting mesh bag 2. The discharge ejection device 4 includes a foldable bridging component that overlaps between the small door 1 and the bottle-sorting mesh bag 2. The bridging component is provided with a bottle-sorting discharge push plate 48, which pushes the vials in the small door 1 onto the bottle-sorting mesh bag 2. The bridging component connects the small door 1 and the bottle-sorting mesh bag 2 through a flipping action, reducing the idle space of the equipment and avoiding interference with the opening and closing of the small door 1.

[0023] When automatic feeding is required, the vials with half-stopped packaging are conveyed along the feeding mesh bag to the vial unscrambling mesh bag 2. The feeding mesh bag and vial unscrambling mesh bag 2 stop working simultaneously, and the push rod mechanism 5 drives the vial unscrambling feeding push plate 3 to advance, pushing the vials on vial unscrambling mesh bag 2 into the freeze-drying chamber. At this time, the vial unscrambling discharge push plate 48 rises to its highest point via the second-direction moving mechanism, ensuring that the vial unscrambling feeding push plate 3 passes smoothly and avoiding mechanical interference. After pushing is completed, the vial unscrambling feeding push plate 3 resets, and vial unscrambling mesh bag 2 resumes operation.

[0024] When automatic discharging is required, the bridging component overlaps between the small door 1 and the bottle-sorting mesh bag 2, forming a transmission channel for transferring vials onto the bottle-sorting mesh bag 2. After the first row of vials passes through the bottle-sorting discharge pusher 48, the rear-pushing mechanism pauses; the bottle-sorting discharge pusher 48 descends and is pushed forward by the first-direction moving mechanism, pushing the isolated single row of vials onto the bottle-sorting mesh bag 2; subsequently, the bottle-sorting discharge pusher 48 resets, and the rear-pushing mechanism continues to push out the next row of vials, repeating the above steps until discharging is complete. The bottle-sorting mesh bag 2 and the discharge mesh bag work synchronously, conveying the freeze-dried vials to the next process.

[0025] For example, the bridging component in this embodiment includes a bearing seat 41 fixed to the front side of the small door 1. A transition flap 42 is rotatably connected to the bearing seat 41, and a bottle feeding and discharging pusher 48 is disposed on the transition flap 42. A flipping pusher 49 is disposed below the transition flap 42. When the flipping pusher 49 is pushed forward, the transition flap 42 and bearing seat 41 flip around the center and become horizontal, which can then connect with the edge of the small door 1 and the bottle feeding and discharging bag 2, facilitating the feeding and discharging of vials. When the flipping pusher 49 is retracted, the transition flap 42 and bearing seat 41 flip around the center and become inclined. At this time, the transition flap 42 and other components are located outside the small door 1, facilitating the closing of the small door 1. The transition flap 42 adopts a flip-up configuration, reducing the space it occupies in the isolation chamber, allowing the bottle feeding and discharging bag 2 to be closer to the small door 1, making it easier to push and push vials, and improving feeding and discharging efficiency.

[0026] Furthermore, two bottle-sorting side plates 43 are arranged parallel to each other on both sides of the upper surface of the transition flap 42, forming a space between the two bottle-sorting side plates 43 for the vials to pass through, making the vials more stable during the feeding and discharging process on the transition flap 42.

[0027] Furthermore, the top of the transition flap 42 (i.e. the side facing the small door 1) gradually narrows to form an overlapping edge. When the transition flap 42 is in a horizontal state, the overlapping edge overlaps the small door 1, increasing the docking effect between the transition flap 42 and the small door 1, reducing the docking gap, and making it easier for vials to pass through.

[0028] To ensure a stable transfer of freeze-dried vials from the small door 1 to the vial-collecting mesh bag 2, this embodiment features sidewall frames 44 positioned opposite each other on both sides of the transition flap 42. The sidewall frames 44 are equipped with a first-direction moving mechanism and a second-direction moving mechanism. The first-direction moving mechanism drives the vial-collecting discharge pusher 48 to move horizontally, pushing a single row of vials from the small door 1 onto the vial-collecting mesh bag 2 with each horizontal movement. The second-direction moving mechanism drives the first-direction moving mechanism and the vial-collecting discharge pusher 48 to move vertically. When the vial-collecting discharge pusher 48 reaches its highest point, a passage gap 410 is formed between the vial-collecting discharge pusher 48 and the transition flap 42, allowing the vials to pass through. In this embodiment, one function of the passage gap 410 is for feeding. For example, the second directional moving mechanism drives the bottle-discharging pusher plate 48 to rise to its highest point. At this time, the vials on the bottle-feeding pusher plate 3 and the bottle-feeding mesh bag 2 are pushed through the material passage gap 410 and transported to the freeze-drying plate layer inside the small door 1. The second function of the material passage gap 410 is for discharging. For example, during discharging, the second directional moving mechanism drives the bottle-discharging pusher plate 48 to rise to its highest point. The rear pusher mechanism set at the rear of the freeze dryer in the prior art pushes out the vials on the freeze-drying plate layer inside the freeze dryer. When the first row of vials passes through the bottle-discharging pusher plate 48, the rear pusher mechanism stops working. At this time, the second directional moving mechanism drives the bottle-discharging pusher plate 48 to fall. Then, the first directional moving mechanism works to push the bottle-discharging pusher plate 48 forward, pushing the first row of vials separated by the bottle-discharging pusher plate 48 along the bottle-feeding mesh bag 2 onto the bottle-feeding mesh bag 2. Then the second directional moving mechanism and the first directional moving mechanism reset and repeat the above discharging steps.

[0029] It should be noted that the height of the material passage gap 410 is A, and the height of the bottle feeding pusher plate 3 is B, where A > B. The width of the material passage gap 410 is a, and the width of the bottle feeding pusher plate 3 is b, where a > b. This arrangement ensures that the bottle feeding pusher plate 3 is smaller than the material passage gap 410, facilitating its passage through the gap.

[0030] For example, the second directional movement mechanism includes a vertical push rod 45 fixed above the side wall frame 44, and a slider 46 is provided at the output end of the vertical push rod 45. The first directional movement mechanism and the bottle-discharging push plate 48 are disposed on the slider 46. In addition, a strip-shaped slot is opened in the vertical direction of the side wall frame 44 for the slider 46 to pass through. During operation, the slider 46, the first directional movement mechanism, and the bottle-discharging push plate 48 move up and down by pushing and pulling the vertical push rod 45.

[0031] For example, the first directional movement mechanism includes a horizontal push rod 47 disposed on the rear side of the slider 46. The output end of the horizontal push rod 47 passes through the slider 46 and is fixed to the bottle discharge push plate 48. During operation, the advancement of the horizontal push rod 47 causes the bottle discharge push plate 48 to push the vials onto the bottle feeding bag 2.

[0032] The aforementioned vertical push rod 45, horizontal push rod 47, and flip push rod 49 are all electrically operated telescopic rods.

[0033] 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.
