Description

Technical Field

[0002] The existing tray-freeze-dried API freeze-dried powder pouring device lacks an automatic pouring device, and the tray needs to be manually tipped to pour the powder into a collection device. During this process, the operator needs to wear multiple layers of sterile clothing and work in a Class A laminar flow environment. However, tipping the tray is a very heavy physical exertion, which is a burden on the operator, and the manual tipping of the tray is inefficient and cannot meet the customer's speed requirements. In addition, the long-term contact between the operator and the drug greatly increases the possibility of drug contamination. Under the increasingly stringent pharmaceutical GMP requirements, the requirements for the automation of drug transportation are also increasing. Therefore, it is particularly important to provide an automated equipment that can automatically transport API freeze-dried powder trays and flip and pour materials. Utility Model Content

[0036] The structure and effects of the present application are further described in detail below in conjunction with the accompanying drawings.

[0037] The present application embodiment discloses a transport, flipping and unloading mechanism for a freeze-drying tray. Figure 1 and Figure 2 The conveying, flipping and unloading mechanism of the freeze-drying tray includes an equipment bottom plate 1, a conveying component 2, a driving component 3, a clamping and oscillating component 4 and a receiving component 5. Among them, a discharge port 7 is opened through the equipment bottom plate 1, and the discharge end of the receiving component 5 is arranged opposite to the discharge port 7, so that the material guided by the receiving component 5 can flow out through the discharge port 7 and enter the collection container for storage.

[0038] Reference Figure 1 and Figure 2 The conveying assembly 2 is arranged on the bottom plate 1 of the equipment, and includes a mounting frame, a driving roller, a driven roller and a conveying drive (not shown in the figure). In this embodiment, two driving rollers are arranged, and seven driven rollers are arranged. Both the driving rollers and the driven rollers are rotatably arranged between two opposite side walls of the mounting frame and are connected by an O-belt transmission. The conveying drive is arranged on the mounting frame, and the driving roller is controlled by the conveying drive, which is a speed-adjustable driver.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The driving assembly 3 is arranged on the bottom plate 1 of the equipment, and includes a flip driving member 31, a transmission member 32, a reducer 33 and a mounting seat 34. Among them, the flip driving member 31 is arranged at the bottom of the bottom plate 1 of the equipment, and is a servo motor. Isolating the flip driving member 31 from the material pouring space can prevent the motor from contaminating the material. The transmission member 32 is arranged through the bottom plate 1 of the equipment, and is connected to the flip driving member 31. The transmission member 32 includes a housing 321 and a transmission shaft 322 rotatably arranged in the housing 321. Both ends of the transmission shaft 322 are rotatably connected to the housing 321 through bearings 323. A dynamic seal is provided in the middle of the transmission shaft 322 to achieve the sealing of the material pouring space. The reducer 33 is arranged at one end of the transmission member 32 away from the flip driving member 31. The mounting seat 34 is arranged on the reducer 33 and is fixed to the housing 321 of the transmission member 32.

[0040] Reference Figure 1 and Figure 2 The clamping oscillation component 4 is arranged on the conveying component 2, and is used to clamp and oscillate the pallet, and includes a clamping drive 41, a clamping block 42, an oscillating member 43 and a photoelectric sensor 44. The clamping drive 41 is arranged on the conveying component 2, and is a clamping cylinder. Two clamping blocks 42 are provided, and are relatively arranged on the mounting frames on both sides of the conveying component 2, one of which is fixed to the output end of the clamping drive 41, and a flange structure is arranged on the upper part of the clamping block 42, which is used to clamp the pallet to prevent it from falling during the flipping process, and the other clamping block 42 is fixed on the mounting frame. The oscillating member 43 is arranged on the clamping block 42 fixed to the clamping drive 41, and is used to oscillate the pallet. After the pallet flips more than 90°, it starts to vibrate, so that the material is separated from the pallet and the discharge rate is increased. The photoelectric sensor 44 is arranged on the conveying component 2, and is used to detect whether the pallet is in place, and automatically recognizes and clamps the pallet after it is in place. In this embodiment, the clamping block 42 is a polyurethane clamping block.

[0041] Reference Figure 1 and Figure 2 The material receiving component 5 is a material receiving hopper and is arranged at the bottom of the conveying component 2.

[0042] Reference Figure 1 and Figure 2 A support leg 6 is also provided on the equipment bottom plate 1. One end of the support leg 6 away from the equipment bottom plate 1 is rotatably connected to the conveying component 2, and supports the conveying component 2 to improve the stability of the conveying component 2.
