Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery and equipment, and in particular to an automatic unloading machine and an automatic unloading method. Background Technology

[0002] In freeze-drying logistics lines, the freeze-drying process requires that medicine bottles not be placed on trays with bottom supports in the freeze-drying cabinet, but rather on frames so that the bottles directly contact the freeze-drying layer. Currently, after the products are freeze-dried, most of the unloading of frames is done manually or semi-automatically, which is labor-intensive and has low production efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic unloading machine and automatic unloading method with a reasonable layout that is conducive to reducing labor intensity and improving production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An automatic frame unloading machine includes a full-frame input conveyor belt, a bottle conveyor belt, an unloading platform disposed between the full-frame input conveyor belt and the bottle conveyor belt, an exit conveyor belt disposed on one side of the unloading platform, a bottle pushing mechanism for pushing frames on the full-frame input conveyor belt to the unloading platform and for pushing unloaded bottles onto the bottle conveyor belt, and an exit mechanism for pushing frames on the unloading platform onto the exit conveyor belt. The unloading platform is provided with a frame recess for frames to fall into, and a lifting and lowering top frame mechanism is provided below the frame recess.

[0006] As a further improvement to the above technical solution:

[0007] The top frame mechanism includes a top frame component and a top frame drive component for driving the top frame component to rise and fall.

[0008] The frame ejection mechanism includes a frame ejection guide, a frame ejection lifting seat, and a frame retrieval plate. The frame ejection guide is located on one side of the frame ejection mesh belt, the frame ejection lifting seat is slidably mounted on the frame ejection guide, and the frame retrieval plate is located on the frame ejection lifting seat.

[0009] The bottle conveyor belt is connected to a buffer conveyor belt.

[0010] The automatic unloading machine also includes a bottle protection mechanism that protects the bottle when the bottle pushing mechanism pushes the bottle.

[0011] The bottle protection mechanism includes a bottle protection plate, a bottle protection guide rod, and a bottle protection lifting seat. The bottle protection guide rod is mounted on the bottle protection lifting seat, and the bottle protection plate is slidably mounted on the bottle protection guide rod.

[0012] A bottle-blocking mechanism that can be raised and lowered is provided between the bottle conveyor belt and the unloading platform.

[0013] The bottle-blocking mechanism includes a bottle-blocking plate and a bottle-blocking lifting seat, with the bottle-blocking plate mounted on the bottle-blocking lifting seat.

[0014] The bottle pushing mechanism includes a bottle pushing plate, a bottle pushing lifting seat, and a bottle pushing guide. The bottle pushing guide is located on one side of the full-frame input mesh belt, the bottle pushing lifting seat is slidably mounted on the bottle pushing guide, and the bottle pushing plate is located on the bottle pushing lifting seat.

[0015] An automatic frame unloading method, using the aforementioned automatic frame unloading machine, includes the following steps:

[0016] S1: Full frame input: The full frame of the bottle is conveyed to the unloading platform via the full frame input conveyor belt;

[0017] S2: Pushing the frame: The bottle pushing mechanism pushes the full-frame input mesh belt onto the unloading platform and positions the frame on the top frame mechanism within the recessed frame groove;

[0018] S3: The sleeve frame is inserted into the recessed slot: The top frame mechanism descends, causing the sleeve frame to be inserted into the recessed slot;

[0019] S4: Bottle pushing: The bottle pushing mechanism pushes the bottle body on the unloading platform onto the bottle conveyor belt;

[0020] S5: Top frame: The top frame mechanism rises and pushes the sleeve frame onto the unloading platform;

[0021] S6: Unloading the frame: The unloading mechanism sends the frame from the unloading platform to the unloading conveyor belt.

[0022] Compared with the prior art, the advantages of the present invention are as follows:

[0023] The unloading process of the automatic unloading machine of the present invention is as follows: First, the full-bottle frames are conveyed to one side of the unloading platform via a full-frame input conveyor belt; then, the bottle pushing mechanism pushes the frames on the full-frame input conveyor belt onto the unloading platform, positioning the frames on the top frame mechanism within the frame recess; next, the top frame mechanism descends, causing the frames to sink into the frame recess. The position where the frames sink into the frame recess is such that the front and rear sidewalls of the frames in the pushing direction are below the unloading platform, avoiding obstruction of subsequent bottle pushing actions; the left and right sidewalls of the frames in the pushing direction are higher than the unloading platform. During bottle pushing, the mechanism limits the left and right sides of the bottle stack to prevent bottles from being squeezed out of the unloading platform. Next, the bottle pushing mechanism pushes the bottles onto the conveyor belt, which then outputs them to the next station. After pushing, the mechanism returns to its original position. Then, the top frame mechanism rises, placing the frame onto the unloading platform, ensuring the bottom of the frame is not lower than the platform for subsequent unloading. Finally, the frame exit mechanism pushes the frame onto the exit conveyor belt, which outputs the frame, completing the unloading process. This automatic unloading machine uses recessed slots on the unloading platform for unloading, a rational layout and ingenious design. Using this automatic unloading machine reduces labor intensity and improves production efficiency.

[0024] The automatic unloading method of the present invention firstly involves conveying a full-bottle frame to one side of the unloading platform via a full-frame input conveyor belt; then, a bottle-pushing mechanism pushes the frame from the full-frame input conveyor belt onto the unloading platform, positioning the frame on a top frame mechanism within a frame recess; next, the top frame mechanism descends, causing the frame to sink into the frame recess. The position where the frame sinks into the recess is such that the front and rear sidewalls of the frame in the pushing direction are below the unloading platform to avoid obstructing subsequent bottle-pushing actions, while the left and right sidewalls of the frame in the pushing direction are above the unloading platform. During bottle pushing, the mechanism limits the left and right sides of the bottle stack to prevent bottles from being squeezed out of the unloading platform. Next, the pushing mechanism pushes the bottles onto the conveyor belt, which then transports them to the next station. After pushing, the pushing mechanism returns to its original position. Then, the top frame mechanism rises, placing the frame onto the unloading platform, ensuring the bottom of the frame is not lower than the platform for subsequent unloading. Finally, the ejection mechanism delivers the frame from the unloading platform to the ejection belt, which outputs the frame, completing the unloading process. This automatic unloading method reduces labor intensity and improves production efficiency. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Figures 1 to 5An embodiment of the automatic unloading machine of the present invention is shown. The automatic unloading machine includes a full-frame input conveyor belt 1, a bottle conveyor belt 2, an unloading platform 3 disposed between the full-frame input conveyor belt 1 and the bottle conveyor belt 2, an exit conveyor belt 4 disposed on one side of the unloading platform 3, a bottle pushing mechanism 5 for pushing the frames on the full-frame input conveyor belt 1 onto the unloading platform 3 and for pushing the unloaded bottles onto the bottle conveyor belt 2, and an exit mechanism 6 for pushing the frames on the unloading platform 3 onto the exit conveyor belt 4. The unloading platform 3 is provided with a frame recess 31 for the frames to fall into, and a lifting and lowering top frame mechanism 7 is provided below the frame recess 31. Specifically, the frame is a square frame, and the frame recess 31 is a square groove adapted to the frame, the square groove extending through the upper and lower surfaces of the unloading platform 3. Unloading process: First, the full-filled frames are conveyed to one side of the unloading platform 3 via the full-frame input conveyor belt 1. Next, the bottle pushing mechanism 5 pushes the frames from the full-frame input conveyor belt 1 onto the unloading platform 3, positioning them on the top frame mechanism 7 within the frame recess 31. Then, the top frame mechanism 7 descends, causing the frames to sink into the frame recess 31. The position of the frames within the recess 31 is such that the front and rear sidewalls of the frames in the pushing direction are below the unloading platform 3, avoiding obstruction of subsequent bottle pushing actions. The left and right sidewalls of the frames in the pushing direction are higher than the unloading platform 3, allowing for smooth bottle pushing. The first step is to limit the bottles on the left and right sides of the unloading platform 3, preventing the bottles from being squeezed out from the left and right sides. Next, the bottle pushing mechanism 5 pushes the bottles on the unloading platform 3 onto the bottle conveyor belt 2, which then outputs the bottles to the next station. After pushing the bottles, the bottle pushing mechanism 5 returns to its original position. Then, the top frame mechanism 7 rises, placing the frame onto the unloading platform 3, ensuring that the bottom of the frame is not lower than the unloading platform 3, facilitating subsequent unloading operations. Finally, the frame exit mechanism 6 pushes the frame onto the frame exit belt 4, which outputs the frame, completing the unloading process. This automatic unloading machine uses a frame slot 31 on the unloading platform 3 for unloading, which is a reasonable layout and ingenious design. Using this automatic unloading machine helps reduce labor intensity and improve production efficiency.

[0034] In this embodiment, as Figure 3 and Figure 5 As shown, the top frame mechanism 7 includes a top frame member 71 and a top frame drive member 72 for driving the top frame member 71 to rise and fall. The top frame member 71 can be designed as a U-shaped plate, with both sides of the U-shaped plate extending into the recessed frame groove 31 and pressing against the sleeve frame. Of course, the top frame member 71 can also be designed to extend into the recessed frame groove 31. The top frame member 71 is fixed to the top frame drive member 72 and is driven to rise and fall by the top frame drive member 72, which can be a lifting cylinder.

[0035] In this embodiment, as Figure 1 , Figure 2 and Figure 5As shown, the frame ejection mechanism 6 includes a frame ejection guide 61, a frame ejection lifting seat 62, and a frame removal plate 63. The frame ejection guide 61 is located on one side of the frame ejection conveyor belt 4, the frame ejection lifting seat 62 is slidably mounted on the frame ejection guide 61, and the frame removal plate 63 is mounted on the frame ejection lifting seat 62. The frame removal plate 63 is a hook-shaped plate. The frame ejection conveyor belt 4 is arranged along the conveying direction of the frame ejection conveyor belt 4. The frame ejection lifting seat 62 can move along the frame ejection guide 61 and can be adjusted up and down, thereby moving the frame removal plate 63 above the unloading platform 3 to hook the frame and pull it onto the frame ejection conveyor belt 4. The frame ejection guide 61 is preferably a frame ejection servo electric cylinder.

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, the bottle conveyor belt 2 is connected to a buffer conveyor belt 21. The buffer conveyor belt 21 is used for bottle buffering.

[0037] In this embodiment, the automatic unloading machine also includes a bottle protection mechanism 8 that protects the bottles when the bottle pushing mechanism 5 pushes them. The bottle protection mechanism 8 is used to protect the front side of the bottle row in the pushing direction when the bottle pushing mechanism 5 pushes the bottles, preventing the bottles from tipping over.

[0038] In this embodiment, as Figures 1 to 5 As shown, the bottle protection mechanism 8 includes a bottle protection plate 81, a bottle protection guide rod 82, and a bottle protection lifting seat 83. The bottle protection guide rod 82 is mounted on the bottle protection lifting seat 83, and the bottle protection plate 81 is slidably mounted on the bottle protection guide rod 82. During bottle protection, the bottle protection lifting seat 83 slides along the bottle protection guide rod 82 to the bottle protection position, and lowers the bottle protection plate 81 to protect the front side of the bottle pack in the pushing direction, and moves the bottle protection plate 81 with the movement of the bottle. After the bottle protection is completed, the bottle protection lifting seat 83 raises the bottle protection plate 81 to prevent obstruction of the bottle being pushed onto the bottle conveyor belt 2.

[0039] In this embodiment, as Figure 1 and Figure 2 As shown, a lifting bottle-blocking mechanism 9 is provided between the bottle conveyor belt 2 and the unloading platform 3. Before the bottle guard plate 81 approaches the bottle-blocking mechanism 9, the bottle-blocking mechanism 9 blocks between the bottle conveyor belt 2 and the unloading platform 3, playing a role in isolation; when the bottle guard plate 81 approaches the bottle-blocking mechanism 9, the bottle-blocking mechanism 9 rises, so that the bottle can be smoothly pushed onto the bottle conveyor belt 2.

[0040] In this embodiment, as Figure 1 and Figure 2 As shown, the bottle-blocking mechanism 9 includes a bottle-blocking plate 91 and a bottle-blocking lifting seat 92, with the bottle-blocking plate 91 mounted on the bottle-blocking lifting seat 92. The bottle-blocking lifting seat 92 is used to raise and lower the bottle-blocking plate 91. Before the bottle-protecting plate 81 approaches the bottle-blocking mechanism 9, the bottle-blocking plate 91 blocks the bottle conveyor belt 2 and the unloading platform 3, serving as an isolation function. When the bottle-protecting plate 81 approaches the bottle-blocking mechanism 9, the bottle-blocking lifting seat 92 raises the bottle-blocking plate 91, allowing the bottle to be smoothly pushed onto the bottle conveyor belt 2.

[0041] In this embodiment, the bottle pushing mechanism 5 includes a bottle pushing plate 51, a bottle pushing lifting seat 52, and a bottle pushing guide 53. The bottle pushing guide 53 is located on one side of the full-frame input conveyor belt 1, the bottle pushing lifting seat 52 is slidably mounted on the bottle pushing guide 53, and the bottle pushing plate 51 is mounted on the bottle pushing lifting seat 52. The bottle pushing guide 53 is arranged along the conveying direction of the full-frame input conveyor belt 1. The bottle pushing lifting seat 52 can slide along the bottle pushing guide 53 and can adjust the height of the bottle pushing plate 51. When pushing the frame, the bottle pushing plate 51 pushes the frame on the rear side of the frame in the pushing direction. The bottle pushing lifting seat 52 slides along the bottle pushing guide 53, and the bottle pushing plate 51 moves synchronously to push the frame onto the unloading platform 3. After the frame is inserted into the frame recess 31, the bottle pushing lifting seat 52 continues to slide along the bottle pushing guide 53, and the bottle pushing plate 51 moves synchronously to push the frame-removed bottle onto the conveyor belt 2.

[0042] An automatic frame unloading method, using an automatic frame unloading machine, includes the following steps:

[0043] S1: Full frame input: The full frame of the bottle is conveyed to one side of the unloading platform 3 via the full frame input mesh belt 1;

[0044] S2: Pushing the frame: The bottle pushing mechanism 5 pushes the frame on the full frame input conveyor belt 1 to the unloading platform 3, and places the frame on the top frame mechanism 7 in the frame recess 31;

[0045] S3: The sleeve frame is inserted into the recessed slot 31: The top frame mechanism 7 descends, causing the sleeve frame to be inserted into the recessed slot 31;

[0046] S4: Bottle pushing: The bottle pushing mechanism 5 pushes the bottle body on the unloading platform 3 onto the bottle conveyor belt 2;

[0047] S5: Top frame: The top frame mechanism 7 rises and pushes the sleeve frame onto the unloading platform 3;

[0048] S6: Unloading the frame: The unloading mechanism 6 sends the frame on the unloading platform 3 to the unloading conveyor belt 4.

[0049] First, the full-bottle frame is conveyed to one side of the unloading platform 3 via the full-frame input conveyor belt 1. Next, the bottle pushing mechanism 5 pushes the frame from the full-frame input conveyor belt 1 onto the unloading platform 3, positioning the frame on the top frame mechanism 7 within the frame recess 31. Then, the top frame mechanism 7 descends, causing the frame to sink into the frame recess 31. The position of the frame sinking into the frame recess 31 is such that the front and rear sidewalls of the frame in the pushing direction are below the unloading platform 3, avoiding obstruction of subsequent bottle pushing actions. The left and right sidewalls of the frame in the pushing direction are higher than the unloading platform 3, allowing for smoother bottle pushing during operation. The left and right sides of the bottle rack act as limiters to prevent bottles from being squeezed out of the unloading platform 3. Next, the bottle pushing mechanism 5 pushes the bottles on the unloading platform 3 onto the bottle conveyor belt 2, which then outputs the bottles to the next station. After pushing, the bottle pushing mechanism 5 returns to its original position. Then, the top frame mechanism 7 rises, placing the frame onto the unloading platform 3, ensuring the bottom of the frame is not lower than the platform 3, facilitating subsequent unloading. Finally, the frame exit mechanism 6 delivers the frame from the unloading platform 3 to the frame exit belt 4, which outputs the frame, completing the unloading process. This automatic unloading method helps reduce labor intensity and improve production efficiency.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them 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 scope of the present invention, should fall within the protection scope of the present invention.
