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 material inlet and outlet transportation device and a material inlet and outlet method. Background Art

[0002] At present, the way for raw materials to enter and exit the freeze dryer is generally to use a freeze drying tray and an inlet and outlet transportation device. The freeze drying tray is placed on the inlet and outlet transportation device, and the drug solution is filled into the membrane frame before being sent to the freeze dryer, and then the freeze dryer is put into the freeze dryer. The freeze drying tray is difficult to clean, and there is a lot of residue, which increases the amount of waste. In the process of scraping the drug powder blocks in the freeze drying tray, the problem of metal particles is generated; there are also some methods that use a membrane frame and an inlet and outlet transportation device. The membrane frame is placed on the inlet and outlet transportation device, and the drug solution is filled into the membrane frame before being sent into the freeze dryer, and then the freeze dryer is put into the freeze dryer. Since the membrane frame is filled with liquid before being sent into the freeze dryer, the membrane will collapse downward, rub on the platform, generate particles, and easily wear the PE membrane, causing leakage problems. When loading materials into the freeze dryer, the membrane frame enters the freeze dryer first, and then the liquid is input into the membrane frame through the infusion tube. However, there will be residual liquid in the infusion tube, and when the infusion tube exits the freeze dryer, the infusion tube will drip the residual liquid in the infusion tube onto the freeze dryer plate layer due to folding or vibration.

[0008] The discharge valve includes a valve, a valve stem and a tightening block, one side of the valve is hinged to one side of the discharge port, the valve stem is arranged on the other side of the valve, the tightening block is arranged on the lifting frame, and the feeding trolley is provided with a lifting platform for lifting the pre-filling tray. When the pre-filling tray is flipped down and supported on the lifting platform and the lifting frame is in a high position, the tightening block tightens the valve stem to make the valve close the discharge port.

[0009] The pre-filling disc is provided with a limiter for limiting the opening angle of the valve.

[0010] An articulated seat is arranged at one end of the fork frame away from the feeding trolley, and the pre-filling plate is articulated with the articulated seat.

[0011] The top of the pre-filled tray is open.

[0012] A freeze-drying tray is supported on a lifting frame adjacent to the fork frame.

[0013] The freeze-drying tray includes a tray body, a support frame and a material containing film. The material containing film is laid in the tray body, the edge of the material containing film is attached to the upper edge of the tray body, the support frame is pressed on the edge of the material containing film, and lifting blocks are provided on both sides of the tray body, and the lifting blocks are supported on the lifting frames.

[0017] S3, feeding: the feeding trolley transports the pre-filled trays and freeze-dried trays filled with liquid medicine into the freeze dryer;

[0018] S4, filling liquid: lift the frame to lower the freeze-drying tray to the lowest position, and fill the pre-filled tray with the liquid medicine into the freeze-drying tray;

[0019] S5. The feeding trolley exits: the freeze-drying tray remains in the freeze dryer and the feeding trolley exits.

[0020] As a further improvement of the above technical solution:

[0021] The feeding and discharging method further comprises the following discharging steps:

[0022] S6, tray out: After freeze drying is completed, the feeding cart enters the freeze dryer to take out the freeze dried tray;

[0023] S7, unloading: unload the freeze-drying tray from the feeding cart, collect the drug materials and bag them.

Because a pre-filling tray is provided, it is not necessary to fill the freeze-drying tray with liquid medicine before sending it into the freeze dryer. Instead, it is pre-filled in the pre-filling tray. After entering the freeze dryer, the liquid medicine in the pre-filling tray is then filled into the freeze-drying tray, which prevents the freeze-drying tray from collapsing due to the gravity of the liquid medicine before entering the freeze dryer, thereby causing friction with the platform, generating particles, and causing leakage. In addition, it is no longer necessary to use an infusion tube to input liquid into the freeze-drying tray in the freeze dryer, thus avoiding the waste of residual liquid in the infusion tube and the problem of pulling the tube in and out of the freeze dryer. In addition, it prevents the residual liquid in the infusion tube from dripping onto the freeze dryer plate layer, causing subsequent cleaning difficulties. This material input and output transportation device avoids the problem of leakage caused by friction damage to the freeze-drying tray, and avoids the waste of residual liquid in the infusion tube and the problem of pulling the tube in and out of the freeze dryer.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Figures 1 to 7 An embodiment of the in-and-out material transport device of the present invention is shown, and the freeze-dried tray and the in-and-out material transport device include a feeding trolley 4 and at least two fork frames 5, each fork frame 5 is arranged in parallel at the front end of the feeding trolley 4, and a lifting frame 6 and a lifting drive mechanism 7 for driving the lifting frame 6 to rise and fall are arranged on the fork frame 5, and a pre-filling tray 8 is hinged between adjacent fork frames 5, and a lifting port 52 for the freeze-dried tray to enter and exit is formed below the pre-filling tray 8. The pre-filling tray 8 is hinged between adjacent fork frames 5 to achieve a connection that can be turned upside down.

[0038] The loading and unloading process of the loading and unloading transport device is as follows: first, the freeze-dried tray is inserted into the fork frame 5 below the pre-filled tray 8 through the lifting port 52, so that the freeze-dried tray is supported on the lifting frame 6 of the adjacent fork frame 5, and the pre-filled tray 8 is placed flat on the freeze-dried tray; secondly, the lifting frame 6 lifts the pre-filled tray 8 to a high position (such as Figure 6 As shown), the predetermined liquid medicine is poured into the pre-filled tray 8; then, the feeding trolley 4 transports the pre-filled tray 8 filled with liquid medicine and the freeze-dried tray to the freeze dryer; then, the lifting frame 6 lowers the freeze-dried tray to a low position (as shown in FIG. Figure 7As shown), the Chinese medicine liquid in the pre-filled tray 8 is filled into the freeze-drying tray; finally, the freeze-drying tray remains in the freeze dryer, and the feeding trolley 4 withdraws to complete the feeding; after the freeze-drying tray is completely freeze-dried in the freeze dryer, the feeding trolley 4 enters the freeze dryer to take out the freeze-drying tray, and then unloads the freeze-drying tray from the feeding trolley 4, collects the medicinal materials and packs them in bags. Since the pre-filling tray 8 is provided, it is not necessary to fill the freeze-drying tray with liquid medicine before sending it into the freeze dryer. Instead, it is pre-filled in the pre-filling tray 8. After entering the freeze dryer, the liquid medicine in the pre-filling tray 8 is filled into the freeze-drying tray, which prevents the freeze-drying tray from collapsing due to the gravity of the liquid medicine before entering the freeze dryer, thereby causing friction with the platform, generating particles, and causing leakage. In addition, it is no longer necessary to use an infusion tube to input the liquid into the freeze-drying tray in the freeze dryer, thereby avoiding the waste of residual liquid caused by the infusion tube and the problem of pulling the tube in and out of the freeze dryer. In addition, it prevents the residual liquid in the infusion tube from dripping on the freeze dryer plate layer, causing subsequent cleaning difficulties. The present inlet and outlet transportation device avoids the problem of leakage caused by friction damage to the freeze-drying tray, and avoids the waste of residual liquid caused by the infusion tube and the problem of pulling the tube in and out of the freeze dryer. The present inlet and outlet transportation device is easy to operate and can reduce wear and tear and waste of liquid medicine.

[0039] In this embodiment, Figure 2 As shown, a discharge port 81 is provided at the bottom of the pre-filling tray 8, and a discharge valve 9 is provided at the discharge port 81. Before entering the freeze dryer, the discharge valve 9 is closed, and after the material is delivered to the freeze dryer and in place, the discharge valve 9 is opened again to pour the liquid medicine in the pre-filling tray 8 into the freeze drying tray below.

[0040] In this embodiment, Figure 2 As shown, the discharge valve 9 includes a valve 91, a valve stem 92 and a tightening block 93. One side of the valve 91 is hinged to one side of the discharge port 81, the valve stem 92 is arranged on the other side of the valve 91, and the tightening block 93 is arranged on the lifting frame 6. The feeding trolley 4 is provided with a lifting platform 41 for lifting the pre-filling tray 8. When the pre-filling tray 8 is flipped down and supported on the lifting platform 41 and the lifting frame 6 is in a high position, the tightening block 93 tightens the valve stem 92, so that the valve 91 closes the discharge port 81.

[0041] Before pre-filling, the freeze-drying tray is supported on the lifting frame 6 of the adjacent fork frame 5, the pre-filling tray 8 is turned down and placed flat on the freeze-drying tray, the lifting frame 6 rises to a high position, and the tightening block 93 on the lifting frame 6 presses the valve stem 92, so that the valve 91 closes the discharge port 81; after the pre-filling in the pre-filling tray 8 is completed, the feeding trolley 4 transports the pre-filling tray 8 and the freeze-drying tray filled with liquid medicine to the freeze dryer, and the lifting frame 6 is kept at a high position during the feeding process; when filling inside the freeze dryer, the lifting frame 6 drops to a low position, and the freeze-drying tray drops to a low position accordingly, and the tightening block 93 on the lifting frame 6 releases the tightening effect on the valve stem 92, and the valve stem 92 flips downward under the action of gravity to open the discharge port 81, thereby filling the liquid medicine in the pre-filling tray 8 into the freeze-drying tray. The discharge valve 9 has a simple structure and a clever design. It can realize automatic opening and closing by means of its own gravity and the lifting action of the lifting frame 6, so that the feeding of the inlet and outlet transportation device is fast and convenient.

[0042] In this embodiment, Figure 2 As shown, the pre-filling tray 8 is provided with a stopper 82 for limiting the opening angle of the valve 91. The stopper 82 is used to limit the opening angle of the valve 91 so that the opening angle of the valve 91 is not too large, and ensures that when the pre-filling tray 8 is turned down, the valve stem 92 is always located above the tightening block 93, so that when the lifting frame 6 is in a high position, the valve stem 92 can be tightened to close the valve 91.

[0043] In this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, one end of the fork frame 5 away from the feeding trolley 4 is provided with an articulated seat 51, and the pre-filling tray 8 is hinged to the articulated seat 51. The top of the pre-filling tray 8 is open for easy filling.

[0044] In this embodiment, a freeze-drying tray is supported on the lifting frame 6 adjacent to the fork frame 5 .

[0045] In this embodiment, Figure 5 As shown, the freeze drying tray includes a tray body 1, a support frame 2 and a material containing film 3. The material containing film 3 is laid in the tray body 1, the edge of the material containing film 3 is attached to the upper edge of the tray body 1, the support frame 2 is pressed on the edge of the material containing film 3, and both sides of the tray body 1 are provided with lifting blocks 11, and the lifting blocks 11 are supported on the lifting frame 6. The material containing film 3 is used to contain materials, which can avoid direct contact between the materials and the tray body 1. After freeze drying, the support frame 2 can be removed, and the powder can be wrapped with the material containing film 3, and then introduced into the collection bag after rubbing. Because the film is flexible and has no dead angle, a high recovery rate can be achieved. The film is no longer used after use and does not need to be cleaned. After freeze drying, the product does not contact the tray body 1, which has a protective effect on the tray body 1 and prevents the drug solution from corroding the tray body 1.

[0046] A feeding and unloading method, using the above-mentioned feeding and unloading transport device, comprises the following feeding steps:

[0047] S1. Place the freeze-dried tray: Place the freeze-dried tray on the lifting frame 6 adjacent to the fork frame 5, and place the pre-filled tray 8 flat on the freeze-dried tray;

[0048] S2, external filling: the lifting frame 6 lifts the pre-filling tray 8 to a high position, and fills the pre-filling tray 8 with a predetermined liquid medicine;

[0049] S3, feeding: the feeding trolley 4 transports the pre-filled tray 8 filled with liquid medicine and the freeze-dried tray into the freeze dryer;

[0050] S4, filling liquid: lift the frame 6 to lower the freeze-drying plate to a low position, and fill the pre-filled plate 8 with the Chinese medicine liquid into the freeze-drying plate;

[0051] S5, the feeding trolley 4 exits: the freeze-drying tray remains in the freeze dryer, and the feeding trolley 4 exits.

[0052] Since the liquid medicine is pre-filled through the pre-filling tray 8, it is not necessary to fill the freeze-drying tray with liquid medicine before sending it into the freeze dryer. Instead, it is pre-filled in the pre-filling tray 8. After entering the freeze dryer, the liquid medicine in the pre-filling tray 8 is filled into the freeze-drying tray, which prevents the freeze-drying tray from collapsing downward due to the gravity of the liquid medicine before entering the freeze dryer, thereby causing friction with the platform, generating particles, and causing leakage. In addition, it is no longer necessary to use an infusion tube to input the liquid into the freeze-drying tray in the freeze dryer, avoiding the waste of residual liquid in the infusion tube and the problem of pulling the tube in and out of the freeze dryer. In addition, it prevents the residual liquid in the infusion tube from dripping onto the freeze dryer plate layer, causing subsequent cleaning difficulties. This feeding and discharging method avoids the problem of leakage caused by friction damage to the freeze-drying tray and avoids the waste of residual liquid in the infusion tube and the problem of pulling the tube in and out of the freeze dryer.

[0053] In this embodiment, the material feeding and discharging method further includes the following discharging steps:

[0054] S6, tray out: After freeze drying is completed, the feeding trolley 4 enters the freeze dryer to take out the freeze dried tray;

[0055] S7, unloading: unloading the freeze-drying tray from the feeding trolley 4, collecting the medicinal materials and bagging them.

[0056] Specifically, steps S1 to S5 are repeated until the freeze drying tray is filled with the freeze drying machine plate layer. After freeze drying is completed, the drug liquid becomes drug powder, and steps S6 to S7 are performed. The feeding trolley 4 takes out the freeze drying tray, the support frame 2 is manually removed, the powder is collected, and introduced into the collection bag.

Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
