[0048] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0049] Example:

[0050] See also Figure 1 and Figure 2 This embodiment discloses an automatic loading device for a freeze dryer, comprising a frame (not shown), a conveyor belt 10, a sorting assembly 20, a pushing assembly 30, and a temporary storage plate 40. The conveyor belt 10 is disposed on the frame and is arranged horizontally.

[0051] A sorting assembly 20 is provided at one end of the conveyor belt 10 , and the sorting assembly 20 is used to arrange all the medicine bottles on the conveyor belt 10 in sequence and in an orderly manner.

[0052] A push assembly 30 and a temporary storage plate 40 are provided on the side of the other end of the conveyor belt 10. The push assembly 30 and the temporary storage plate 40 are located on either side of the conveyor belt 10, respectively. The top surface of the temporary storage plate 40 is located on a horizontal plane and is coplanar with the conveyor belt 10. The push assembly 30 can push all the medicine bottles on the conveyor belt 10 to the temporary storage plate 40.

[0053] In this embodiment, the conveyor belt 10 is first set on the frame, and all the cleaned medicines are sorted in sequence through the sorting component 20 and pushed onto the conveyor belt 10. Then, after multiple medicine bottles move to the pushing component 30 under the action of the conveyor belt 10, the conveyor belt 10 and the sorting component 20 stop working, and the pushing component 30 pushes all the medicine bottles to the temporary storage plate 40 in a direction perpendicular to the conveyor belt 10, and then the sorting component 20 and the conveyor belt 10 work again.

[0054] After the above work is repeated several times, after multiple rows of medicine bottles are pushed to the temporary storage plate 40, the pause time of the sorting component 20 and the conveyor belt 10 is increased, and then the pushing component 30 pushes all the medicine bottles on the temporary storage plate 40 to the material tray of the freeze dryer. Finally, after the pushing component 30 is retracted, the sorting component 20 and the conveyor belt 10 continue to work.

[0055] Through this technical solution, all medicine bottles can be loaded onto the material tray of the freeze dryer efficiently and cleanly.

[0056] In one specific embodiment:

[0057] The sorting assembly 20 includes a base plate 21, a drive plate 22, a first motor (not shown), and a baffle 23. The base plate 21 is disposed on the frame, the top surface of the base plate 21 and the conveyor belt 10 are in the same plane, and one end of the base plate 21 is close to the conveyor belt 10.

[0058] The drive plate 22 is an annular structure with a plurality of notches 24 disposed circumferentially along its edge. The shape of the notches 24 corresponds to the outer contour of the medicine bottle. Generally, the outer contour of the medicine bottle is circular, and in this case, the notches 24 are semicircular. All the notches 24 are closely spaced along the circumference of the drive plate 22, with small gaps between adjacent notches.

[0059] Part of the driving plate 22 is located above the base plate 21 , and the driving plate 22 is mounted on the output shaft of the first motor. The output shaft of the first motor is coaxially arranged with the driving plate 22 , and the first motor is fixedly mounted on the frame.

[0060] In addition, a baffle 23 is provided on the side of the bottom plate 21 away from the driving plate 22. The length direction of the baffle 23 is consistent with the length direction of the bottom plate 21, and there is a gap between the baffle 23 and the driving plate 22. The width of the gap is greater than the diameter of the medicine bottle and less than 1.5 times the diameter of the medicine bottle.

[0061] In this embodiment, all cleaned medicine bottles are distributed onto the bottom plate 21, and the bottle mouths of all medicine bottles are facing upward. Then, driven by the first motor, the medicine bottles are stuck one by one in the notches 24 on the drive plate 22, and under the rotation of the drive plate 22, the sorted medicine bottles are moved to the conveyor belt 10, so that on the conveyor belt 10, all medicine bottles are lined up in a row and conveyed to the front of the pushing component 30.

[0062] In another specific embodiment:

[0063] The pushing assembly 30 includes a push plate 31, a rack 32, a second motor 33 and a second gear 34, wherein the push plate 31 is a long strip structure, the push plate 31 is arranged on the side of the conveyor belt 10, and the length direction of the push plate 31 is consistent with the length direction of the conveyor belt 10.

[0064] A rack 32 is provided on the side of the push plate 31 away from the conveyor belt 10, and is vertically connected to the push plate 31. The rack 32 is also on a horizontal plane and is slidably mounted on the frame. In addition, a second gear 34 is meshed with the rack 32, and the second gear 34 is coaxially mounted on the output shaft of the second motor 33, which is fixed to the frame.

[0065] In this embodiment, when the pushing assembly 30 is required to push the medicine bottles on the conveyor belt 10 to the temporary storage plate 40, the second motor 33 drives the second gear 34 to rotate, and under the meshing relationship between the second gear 34 and the rack 32, the rack 32 drives the push plate 31 to move forward, and then all the medicine bottles are pushed to the temporary storage plate 40 through the push plate 31.

[0066] Preferably, two racks 32 are provided on the back of the push plate 31, and a second gear 34 is engaged with each of the two racks 32. The two second gears 34 are set on the same shaft, and the shaft is connected to the output shaft of the second motor 33 through a pair of bevel gears. Both ends of the shaft are also rotatably set on the frame.

[0067] In another specific embodiment:

[0068] The automatic feeding device further includes a flip plate 41, a third motor 42, a main shaft 43, a drive rod 44, a connecting rod 45, and a stopper 46. One end of the flip plate 41 is rotatably mounted on an end of the temporary storage plate 40 away from the conveyor belt 10, and the top surface of the flip plate 41 can be on the same horizontal plane as the top surface of the conveyor plate.

[0069] The third motor 42 is fixedly mounted on the frame, and the output shaft of the third motor 42 is power-connected to the main shaft 43 through a pair of gears. The main shaft 43 and the third motor 42 are both located below the temporary storage plate 40. In addition, both ends of the main shaft 43 are rotatably connected to the frame.

[0070] A support member is rotatably mounted on the main shaft 43 and fixedly connected to the bottom surface of the temporary storage plate 40, thereby providing a rotational connection between the temporary storage plate 40 and the main shaft 43. A drive rod 44 is also fixedly mounted on the main shaft 43. One end of the drive rod 44 is connected to the main shaft 43, and the other end is rotationally connected to one end of a connecting rod 45. The other end of the connecting rod 45 is rotationally connected to the bottom surface of the flip plate 41.

[0071] In addition, two stoppers 46 are respectively provided on the top surfaces of the flip plate 41 and the temporary storage plate 40 , and the two stoppers 46 on the flip plate 41 and the temporary storage plate 40 are respectively provided on both sides thereof.

[0072] At the same time, the distance between the two stoppers 46 is equal to the length of the push plate 31 , so that the push plate 31 can move between the two stoppers 46 .

[0073] In this embodiment, the pushing assembly 30 can push the neatly arranged medicine bottles to the top surface of the temporary storage plate 40 and the flip plate 41. After the work is completed, the main shaft 43 can be driven to rotate by the third motor 42, and then the flip plate 41 can be driven to rotate on the temporary storage plate 40 through the driving rod 44 and the connecting rod 45. In addition, during the rotation of the flip plate 41, the end connected to the temporary storage plate 40 is upwardly tilted, so that this end of the temporary storage plate 40 rotates around the main shaft 43, thereby realizing the folding of the temporary storage plate 40 and the flip plate 41.

[0074] Therefore, through this technical solution, the space area occupied by the entire device when idle can be reduced.

[0075] In addition, in order to ensure the stability of the flip plate 41 and the temporary storage plate 40, corresponding supporting structures are provided on the frame so that the two will not shake during operation.

[0076] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
