Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging technology, specifically to a material loading and unloading device for a material frame and a freeze-drying production line. Background Technology

[0002] The automated vial loading and unloading system is mainly used in pharmaceutical, biotechnology and other fields to realize the automatic loading, unloading and transfer of vials, improve production efficiency, reduce manual intervention and ensure a sterile environment.

[0003] Existing freeze dryer feeding and discharging devices, such as the frame-type feeding and discharging method and device for a freeze dryer disclosed in patent CN114279175B, involve the following feeding and discharging method: the rear push rod pushes the material frame into the freeze dryer a certain distance and then resets. Then, the bridge plate drives the material frame to move towards the freeze-drying plate layer. At this time, the front push rod flips upward to avoid the material frame. After the material frame passes the front push rod, the front push rod flips downward and pushes the material frame onto the freeze-drying plate layer, completing the feeding. When the next set of material frames enters the freeze dryer, it hooks the rear end of the previous set of material frames with hooks, so that the material frames are connected in sequence. When discharging, the remaining material frames can be pulled out of the freeze dryer when the last set of material frames is pulled out.

[0004] While this feeding and discharging method can shorten the stroke of the front and rear push rods, the front push rod needs to be flipped during the feeding process, which occupies a large area. Furthermore, each push requires the coordination of both the front and rear push rods, making the operation cumbersome. In addition, to ensure the hooks of the front and rear discharge frames are engaged, starting from the second discharge frame, the bridge plate and push frame assembly need to be raised for each feeding to allow the hooks of the rear frames to engage with the front frames. Therefore, a separate lifting drive is required. Combined with the pushing drive of the front and rear push rods and the flipping drive of the front push rod, this complicates the structure and increases equipment costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a feeding and discharging device and freeze-drying production line for a material frame with a small area occupied by the clamping plate during discharge, a simple feeding and discharging process, and high efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A material loading and unloading device for a material frame includes a push-pull plate, a snap-fit ​​plate, a material pushing drive mechanism, and a moving lifting drive mechanism. The snap-fit ​​plate is connected above the push-pull plate. The material pushing drive mechanism is used to drive the push-pull plate to reciprocate and push material. One end of the material frame is provided with a first snap-fit ​​part. The moving lifting drive mechanism is used to drive the snap-fit ​​plate to move and lift to snap or disengage from the first snap-fit ​​part of the material frame.

[0008] As a further improvement to the above technical solution:

[0009] The mobile lifting drive mechanism includes a transmission block and a drive component for driving the transmission block to move laterally and reciprocally. The transmission block is provided with a vertical groove, the push-pull plate is provided with an arc-shaped groove, and the snap-fit ​​plate is provided with a positioning pin. The positioning pin is movably inserted into the arc-shaped groove and the vertical groove.

[0010] The push-pull plate has multiple push-pull blocks spaced apart along its length, and the snap-fit ​​plate has multiple snap-fit ​​blocks spaced apart along its length. The snap-fit ​​blocks are used to snap into the first snap-fit ​​part of the corresponding material frame. The movement trajectory of the snap-fit ​​blocks is to reciprocate to the side and above the push-pull blocks.

[0011] The push-pull block is provided with a clearance groove, the snap-fit ​​plate is provided with a mounting block, the positioning pin is provided on the mounting block, and the mounting block is movably snapped into the clearance groove.

[0012] The driving component is an electric cylinder, and an electric cylinder mounting plate is provided on the side of the push-pull plate away from the material frame. The arc-shaped groove and the electric cylinder are located on the electric cylinder mounting plate.

[0013] The other end of the material frame is provided with a second locking part, and the second locking part of the rear material frame can lock with the first locking part of the front material frame during lateral movement.

[0014] The first and second locking parts are symmetrical hooks.

[0015] The output shaft of the pusher drive mechanism is connected to the push-pull plate, and the output shaft is fitted with an elastic seal.

[0016] Both sides of the push-pull plate have push sensors.

[0017] A freeze-drying production line includes a conveying device. The input end of the conveying device is provided with a bottle collecting device and a frame device. One side of the middle section of the conveying device is connected to the freeze dryer through a transition plate, and the other side is provided with the aforementioned material frame feeding and discharging device.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] The material feeding and discharging device for the material frame disclosed in this utility model allows for material feeding by a push-pull plate driven by a push-pull mechanism. During discharging, the push-pull plate approaches the material frame, and a lifting and lowering mechanism drives a locking plate to move and descend until it engages with the first locking part of the material frame. Then, the push-pull mechanism drives the push-pull plate to pull the material frame back to achieve discharging. After discharging, the locking plate moves upward to reset, without obstructing the push-pull plate's feeding. Compared to using a flipping method for locking, the stroke area is smaller, and the push-pull mechanism only needs to maintain its initial position throughout the entire feeding process of the push-pull plate, without needing to repeatedly cooperate with the push-pull plate. The process is simple and efficient.

[0020] The freeze-drying production line disclosed in this utility model allows the rear material frames to automatically engage with the first engagement part of the front material frames during the input process via the second engagement part. This eliminates the need for frequent lifting and lowering of the transition plate, resulting in a simple structure, high efficiency, and no obstruction of the material pushing process by the engagement plate. Furthermore, the engagement stroke of the engagement plate during discharge occupies a small area, making the overall process simple and convenient, and effectively improving production efficiency.

[0034] Example 1

[0035] Figures 1 to 7 This invention illustrates an embodiment of the feeding and discharging device for a material frame. The feeding and discharging device of this embodiment includes a push-pull plate 1, a snap-fit ​​plate 2, a pushing drive mechanism 3, and a moving lifting drive mechanism 4. The snap-fit ​​plate 2 is connected above the push-pull plate 1. The pushing drive mechanism 3 is used to drive the push-pull plate 1 to reciprocate and push the material. One end of the material frame 5 is provided with a first snap-fit ​​part 51. The moving lifting drive mechanism 4 is used to drive the snap-fit ​​plate 2 to move and lift, so as to snap or disengage from the first snap-fit ​​part 51 of the material frame 5.

[0036] The feeding and discharging device of this material frame has the following characteristics: During feeding, the pushing drive mechanism 3 drives the push-pull plate 1 to push the material frame 5 to feed the material; During discharging, the push-pull plate 1 approaches the material frame 5, and the moving lifting drive mechanism 4 drives the locking plate 2 to move and descend until it locks into the first locking part 51 of the material frame 5. Then, the pushing drive mechanism 3 drives the push-pull plate 1 to pull the material frame 5 back to achieve discharging. After discharging, the locking plate 2 moves upward to reset and will not obstruct the pushing of the push-pull plate 1. Compared with the method of using flipping to achieve locking, the stroke occupies a small area, and the pushing drive mechanism 3 only needs to maintain the initial position throughout the pushing process of the push-pull plate 1, without having to repeatedly cooperate with the push-pull plate 1. The steps are simple and the efficiency is high.

[0037] Furthermore, such as Figure 2 and Figure 4 As shown, in this embodiment, the movable lifting drive mechanism 4 includes a transmission block 41 and a drive component 42 for driving the transmission block 41 to move laterally and reciprocally. The transmission block 41 is provided with a vertical groove 43, the push-pull plate 1 is provided with an arc-shaped groove 11, and the locking plate 2 is provided with a positioning pin 21. The positioning pin 21 is movably inserted into the arc-shaped groove 11 and the vertical groove 43. The drive component 42 drives the transmission block 41 to move. The transmission block 41 is provided with a vertical groove 43, and the push-pull plate 1 is provided with an arc-shaped groove 11. During the movement of the transmission block 41, the height of the overlapping position of the arc-shaped groove 11 and the vertical groove 43 changes. Since the positioning pin 21 is movably inserted into the arc-shaped groove 11 and the vertical groove 43, the height of the positioning pin 21 changes, ultimately driving the locking plate 2 to lift and lower. The structure is simple, and one drive component 42 can achieve both translation and lifting. Specifically, the positioning pin 21 is located at... Figure 2 In its initial position, the card plate 2 is located in... Figure 3 The positioning pin 21 is located diagonally above the first snap-fit ​​portion 51 shown. Figure 2 Location to run to Figure 4 When in position, the snap-fit ​​plate 2 is also... Figure 3 Location to run to Figure 5 At the position shown, the snap-fit ​​plate 2 snaps into the first snap-fit ​​part 51 to complete the snap-fit. Of course, in other embodiments, the arc-shaped groove 11 can also be other shapes with horizontal and vertical space, such as an L-shaped groove.

[0038] Furthermore, such as Figure 1As shown, in this embodiment, the push-pull plate 1 has multiple push-pull blocks 12 spaced apart along its length, and the latching plate 2 has multiple latching blocks 22 spaced apart along its length. The latching blocks 22 are used to latch with the first latching part 51 of the corresponding material frame 5. The movement trajectory of the latching blocks 22 is a reciprocating motion to the side and above the push-pull block 12. When pushing material, each push-pull block 12 can simultaneously push the frame edge of a row of material frames 5, improving the feeding efficiency. When discharging material, each latching block 22 moves from above the push-pull block 12 to the side and latches with the corresponding first latching part 51. After discharging, it can be reset. Preferably, the latching blocks 22 and the latching plate 2 are detachably connected, which facilitates disassembly and replacement and allows the size of the latching plate 2 to be changed according to the discharging requirements.

[0039] Furthermore, such as Figure 1 As shown, in this embodiment, the push-pull block 12 is provided with a clearance groove 121, the snap-fit ​​plate 2 is provided with a mounting block 23, the positioning pin 21 is provided on the mounting block 23, and the mounting block 23 is movably snapped into the clearance groove 121. This improves the stability of the movement of the snap-fit ​​plate 2, and at the same time, the clearance groove 121 prevents the push-pull block 12 from interfering with the movement of the snap-fit ​​plate 2.

[0040] Furthermore, such as Figure 2 As shown, in this embodiment, the driving component 42 is an electric cylinder. An electric cylinder mounting plate 13 is provided on the side of the push-pull plate 1 away from the material frame 5. The arc-shaped groove 11 and the electric cylinder are located on the electric cylinder mounting plate 13. The structure is simple and easy to install.

[0041] Furthermore, such as Figure 6 and Figure 7 As shown, in this embodiment, the other end of the material frame 5 is provided with a second locking part 52. The second locking part 52 of the rear material frame 5 can engage with the first locking part 51 of the front material frame 5 during lateral movement. With locking parts provided at both the front and rear ends of the material frame 5, the second locking part 52 of the rear material frame 5 can engage with the first locking part 51 of the front material frame 5 during input, eliminating the need to raise the bridge plate and push frame assembly when each row of material frames 5 is input, thus simplifying operation.

[0042] Furthermore, such as Figure 7 As shown, in this embodiment, the first snap-fit ​​portion 51 and the second snap-fit ​​portion 52 are symmetrical hooks. The structure is simple.

[0043] Furthermore, such as Figure 1 As shown, in this embodiment, the output shaft of the pusher drive mechanism 3 is connected to the push-pull plate 1, and an elastic seal 31 is provided on the outer sleeve of the output shaft. The elastic seal 31 can maintain the sealing of the output shaft of the pusher drive mechanism 3 during the extension and retraction process, avoid the transmission components from contaminating the working environment, and improve cleanliness. Preferably, the elastic seal 31 is a bellows, which has a simple structure and low cost.

[0044] Furthermore, such as Figure 1As shown in this embodiment, there are push-material sensors 14 on both sides of the push-pull plate 1. When the material frames 5 are input into place and form a row, the push-material sensors 14 on both sides of the push-pull plate 1 will sense the material frames 5 and start pushing the material.

[0045] Example 2

[0046] Figure 8 This invention illustrates an embodiment of a freeze-drying production line with a material frame. The freeze-drying production line of this embodiment includes a conveying device 6. The input end of the conveying device 6 is provided with a bottle collecting device 7 and a frame-fitting device 8. One side of the middle section of the conveying device 6 is connected to the freeze dryer 92 through a transition plate 91, and the other side is provided with the aforementioned material frame feeding and discharging device.

[0047] The production process of this freeze-drying production line is as follows:

[0048] S1. Bottles are collected and arranged in the bottle collecting device 7, and material frames 5 are fitted in the frame fitting device 8. Material frames 5 are input from the conveying device 6. When the pushing sensor 14 detects that a row of material frames 5 has been conveyed to the front of the freeze dryer 92, the conveying device 6 stops conveying.

[0049] S2. Push-pull plate 1 pushes the discharge frame 5 towards the freeze dryer 92, so that the discharge frame 5 is pushed to the set position of transition plate 91, and then push-pull plate 1 resets.

[0050] S3. The conveying device 6 then conveys the next row of material frames 5. During the conveying process, the next row of material frames 5 is engaged with the first engaging part 51 corresponding to the previous row of material frames 5 through the second engaging part 52. After the next row of material frames 5 is conveyed to the position, the conveying device 6 stops conveying.

[0051] S4. Repeat steps S2 and S3 until the last row of material frames 5 is delivered to the position. Then, push-pull plate 1 pushes the last row of material frames 5 into freeze dryer 92 to complete the feeding.

[0052] S5. During material discharge, the snap plate 2 moves laterally and descends simultaneously, so that each snap block 22 snaps into the first snap part 51 corresponding to the last row of material frames 5.

[0053] S6. Pull the push-pull plate 1 away from the freeze dryer 92 to bring out all the material frames.

[0054] In this freeze-drying production line, during the input process, the material frames 5 in the front and rear rows can be automatically engaged with the first engagement part 51 of the material frames 5 in the front row through the second engagement part 52. This eliminates the need for frequent lifting and lowering of the transition plate 91, resulting in a simple structure and high efficiency. Furthermore, the engagement plate 2 does not obstruct the material pushing process during material feeding, and the engagement stroke of the engagement plate 2 during material discharge occupies a small area. The overall process is simple and convenient, effectively improving production efficiency.

[0055] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
