[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0046] The core of the present utility model is to provide an automatic unloading device for BFS products suitable for four-way shuttle transfer, which can avoid problems such as material extrusion and jamming caused by inaccurate positioning of the processing deviation of the sterilization tray and reduce the floor area to a certain extent.

[0047] It should be noted that the orientation or positional relationship indicated by "upper", "lower", "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0048] An automatic unloading device for BFS products suitable for four-way shuttle transfer provided by the present application (BFS products: products produced by a filling technology, that is, products obtained by Blow-Fill-Seal), includes: a frame 1, a guardrail extraction component 2, a tray conveying component 3, a bottle pushing component 4, a bottle clamping component 6, a bottle lifting component 7, and a sterilization tray positioning conical pin 9;

[0049] Among them, the tray conveying component 3 is arranged on the frame 1, and the tray conveying component 3 is used to transport the sterilization tray filled with materials to the blocking station;

[0050] The guardrail extraction component 2 is arranged on the frame 1 and is used to lift the guardrail on the sterilization tray;

[0051] The bottle pushing component 4 is arranged on the frame 1 and can move in the vertical direction. The bottle pushing component 4 is used to push the materials batch by batch in the column direction to the clamping station;

[0052] The bottle lifting component 7 is arranged at the clamping station and is used to support the materials upward;

[0053] The bottle clamping component 6 is arranged above the clamping station. The bottle clamping component 6 is used to clamp the materials batch by batch and transport them to the designated position;

[0054] The sterilization tray positioning conical pin 9 is connected to the telescopic component and is arranged at the blocking station. The telescopic component is fixed on the frame 1. The telescopic component is used to drive the sterilization tray positioning conical pin 9 to push the sterilization tray towards the clamping station.

[0055] Specifically, please refer to the attached Figure 1 to the attached Figure 3 , the rack 1 is a cuboid frame. There are multiple rows of materials placed in the sterilization tray. The materials are generally ampoule bottles connected in a row. The tray conveying assembly 3 realizes the transportation of the sterilization tray. The sterilization tray is transported from other workstations to the blocking workstation and stops. After reaching the blocking workstation, the positioning conical pin 9 of the sterilization tray is set opposite to the positioning hole on the sterilization tray guardrail. The telescopic assembly pushes out the positioning conical pin 9 of the sterilization tray and inserts it into the positioning hole, which can correct and accurately position the sterilization tray. The telescopic assembly and the positioning conical pin 9 of the sterilization tray push the sterilization tray from the blocking workstation towards the clamping workstation until the sterilization tray is docked with the side 10 of the table board. Then, the guardrail extraction assembly 2 lifts the guardrail of the sterilization tray upward and separates it from the sterilization tray. At this time, the upper surface of the sterilization tray is aligned with the upper surface of the side 10 of the table board. The material is batch-pushed from the blocking workstation to the clamping workstation through the bottle pushing assembly 4. There is a top bottle assembly 7 at the clamping workstation. The material located at the clamping workstation can be jacked up through the top bottle assembly 7. There is a horizontal position difference between the jacked-up material and other materials. Finally, the clamped bottle assembly 6 clamps and transports the jacked-up material to the conveyor belt to facilitate entry into the next process. After unloading the tray, the guardrail extraction assembly 2 returns the guardrail of the sterilization tray to its original position. Similarly, the sterilization tray is taken away through the tray conveying assembly 3.

[0056] It should be noted that the bottle pushing assembly 4 is arranged on the rack 1, and its position is higher than that of the tray conveying assembly 3, the top bottle assembly 7, and the sterilization tray. Moreover, the bottle pushing assembly 4 can be adjusted in the vertical direction. When the bottle pushing assembly 4 descends, it is used to complete the step-by-step material pushing action of the product. After the material pushing is completed, the bottle pushing assembly 4 rises and quickly retracts to the initial bottle pushing position without interfering with the newly transported fully loaded sterilization tray, which reduces the floor area of the equipment to a certain extent.

[0057] Based on the above embodiments, the tray conveying assembly 3 includes a four-way shuttle car 3-1, a transportation guide rail 3-2, and a conveyor belt assembly 3-3. The transportation guide rail 3-2 is used to limit the running track of the four-way shuttle car 3-1. The four-way shuttle car 3-1 is used to transport the sterilization tray to the conveyor belt assembly 3-3. The conveyor belt assembly 3-3 is used to transport the sterilization tray to the blocking workstation.

[0058] Specifically, please refer to the attached Figure 1 and the attached Figure 2 and the attached Figure 8, a lifting assembly is provided on the upper end surface of the four-way shuttle car 3-1. Before the four-way shuttle car 3-1 reaches the conveyor belt assembly 3-3 along the transportation guide rail 3-2, the sterilization tray is lifted by the lifting assembly, so that the bottom surface of the sterilization tray is higher than the conveyor belt assembly 3-3, and it is carried to the conveyor belt assembly 3-3, and is conveyed by the conveyor belt assembly 3-3 to the blocking station for tray unloading operation. After the tray unloading is completed, the sterilization tray is also lifted by the four-way shuttle car 3-1 and transported to the next station.

[0059] Optionally, the four-way shuttle car 3-1 and the conveyor belt assembly 3-3 can be used separately, and the corresponding effects can also be achieved.

[0060] On the basis of the above-mentioned embodiment, a positioning assembly is provided at the blocking station, and the positioning assembly is used to achieve precise positioning of the sterilization tray in the open state.

[0061] Specifically, a detection assembly and a positioning assembly are provided at the blocking station. The positioning assembly can eliminate the grid docking error caused by the rebound of the sterilization tray block and the processing error of the sterilization tray. The detection assembly is used to detect whether the sterilization tray is in place and whether there is still material in the sterilization tray. When the detection assembly detects the approach of the sterilization tray, the positioning assembly is activated and blocks the further movement of the sterilization tray. It can also be understood that under the restriction of the positioning assembly, when the sterilization tray finally stops, the positioning hole on its guardrail corresponds to the positioning conical pin 9 of the sterilization tray. After the detection assembly detects that all the materials in the sterilization tray have been unloaded, it is closed. At this time, the tray conveying mechanism 3 waits for the guardrail extraction assembly 2 to lower the guardrail, and then the sterilization tray can be transported away from the blocking station.

[0062] On the basis of the above-mentioned embodiment, the bottle pushing assembly 4 includes a second cylinder 4-1, a guide shaft 4-2, a support plate 4-3, a third cylinder 4-4, a lifting plate 4-5 and an elastic push plate 4-6. The guide shaft 4-2 is fixed to the frame 1, and the second cylinder 4-1 is arranged on the guide shaft 4-2 and is used to drive the support plate 4-3 to slide along the guide shaft 4-2. The third cylinder 4-4 is arranged on the support plate 4-3 and is used to drive the lifting plate 4-5 and the elastic push plate 4-6 to move in the vertical direction.

[0063] Specifically, please refer to the appendix Figure 9 And the appendix Figure 10 , both the second cylinder 4-1 and the guide shaft 4-2 are components fixed to the frame 1. The second cylinder 4-1 can drive the support plate 4-3, the lifting plate 4-5 and the elastic push plate 4-6 to move in the horizontal direction. Generally speaking, when the second cylinder 4-1 stops on the right side of the frame 1, the third cylinder 4-4 lowers the lifting plate 4-5 and the elastic push plate 4-6, and then controls the second cylinder 4-1 to move to the left. The material is pushed through the elastic push plate 4-6. The elastic push plate 4-6 is used to eliminate the problem that the front row is not neatly arranged due to the gap generated by pushing multiple columns at one time, and ensure the stability and reliability of bottle clamping.

[0064] On the basis of the above embodiments, it further includes a bottle blocking assembly 5, and the bottle blocking assembly 5 includes a fourth cylinder 5-1, a push plate guide rail 5-2 and a cylinder push plate 5-3. Both the fourth cylinder 5-1 and the push plate guide rail 5-2 are fixed to the frame 1, and the cylinder push plate 5-3 is in contact connection with the output end of the fourth cylinder 5-1. The fourth cylinder 5-1 is used to push the cylinder push plate 5-3 to reciprocate in the column direction of the materials.

[0065] Specifically, please refer to the attached Figure 7 , the bottle blocking assembly 5 itself has no power. It relies on the fourth cylinder 5-1 to push the cylinder push plate 5-3 to the outside of the movable edge of the sterilization tray, that is, the left side of the sterilization tray in the attached drawing. At this time, the fourth cylinder 5-1 drives the cylinder push plate 5-3 to retract. The bottle blocking assembly 5 stops at the original position under the action of the damping member. Finally, under the power of the bottle pushing assembly 4, it returns to the original position of the bottle pushing plate. In order to prevent the bottle blocking assembly 5 from toppling the bottles due to its own crosstalk, the bottle blocking assembly 5 is provided with an adjustable damping assembly. Under the action of the damping, the bottle blocking assembly 5 stays outside the left movable edge when pushed by the bottle pushing assembly 4.

[0066] Optionally, a fixed connection can also be selected between the fourth cylinder 5-1 and the cylinder push plate 5-3. When the fourth cylinder 5-1 extends, compressed air is connected, and when the cylinder push plate 5-3 reaches the position, rapid exhaust can also achieve the same function.

[0067] Optionally, the bottle blocking assembly 5 and the guardrail extraction assembly 2 can also adopt structures such as a combination of an electric cylinder and a guide shaft, a combination of a lead screw and a guide shaft, etc., as long as the same technical means can be achieved.

[0068] On the basis of the above embodiments, it further includes a bottle pressing assembly 8. The bottle pressing assembly 8 is arranged between the blocking station and the clamping station. The bottle pressing assembly 8 includes a sixth cylinder 8-1 and a bottle pressing plate 8-2. The sixth cylinder 8-1 is used to push the bottle pressing plate 8-2 in the vertical direction.

[0069] Specifically, please refer to the attached Figure 5 , the bottle pressing assembly 8 is arranged at a position close to the clamping station. Under the action of the sixth cylinder 8-1, the bottle pressing plate 8-2 moves downward and leaves a certain gap with the top of the materials to prevent the materials from bulging during the pushing process and affecting the clamping and handling.

[0070] On the basis of the above embodiments, the guardrail extraction assembly 2 includes a first cylinder 2-1, a horizontal movement assembly 2-2 and a clamping jaw 2-3. The first cylinder 2-1 is used to drive the clamping jaw 2-3 to move in the vertical direction, and the horizontal movement assembly 2-2 is used to drive the first cylinder 2-1 and the clamping jaw 2-3 to move in the horizontal direction.

[0071] Specifically, please refer to the attached Figure 4, there are two centrally located positioning holes inside the movable guardrails on both sides of the sterilization tray. The device of the guardrail extraction component 2 for clamping the guardrails is provided with conical positioning pins, which can ensure that the position of the guardrails will not shift after being clamped and lifted.

[0072] On the basis of the above-mentioned embodiment, the bottle lifting component 7 includes a fifth cylinder 7-1 and a bottle lifting plate 7-2. The fifth cylinder 7-1 is fixed to the frame 1, and the bottle lifting plate 7-2 is a strip-shaped plate.

[0073] Specifically, please refer to the attached Figure 6 , since the arrangement gap between the connected materials is small, in order to ensure the effective opening and closing angle of the clamping jaws of the bottle clamping component 6, a bottle lifting component 7 is provided. The bottle lifting component 7 is located at the first row of grasping positions; at the same time, the bottle lifting component 7 can eliminate the friction with the materials in the second row, improve the stability and success rate of grasping. In addition, the bottle pressing component 8 can also prevent the materials in the second row from being lifted when the bottle lifting component 7 acts.

[0074] It should be noted that both the bottle lifting component 7 and the bottle pressing component 8 are in the form of hinges, effectively avoiding the problem of jamming of the intermediate connecting plate caused by the asynchronous lifting of the cylinders.

[0075] On the basis of the above-mentioned embodiment, it further includes a control system, and the control system is signal-connected to the guardrail extraction component 2, the tray conveying component 3, the bottle pushing component 4, the bottle clamping component 6 and the bottle lifting component 7.

[0076] Specifically, through the control system, unified control of the above-mentioned multiple components can be realized, which is convenient for realizing the automatic operation of the equipment. A bottle detection mechanism is provided at the position where the materials are lifted. When the bottle clamping component 6 does not clamp all the materials in a row for the first time, the bottle clamping component 6 will act again to clamp the remaining bottles for the second time. If there is still a detection signal, an alarm will be sent to notify manual handling.

[0077] Optionally, the bottle clamping component 6 can be a combined structure of a cylinder and a flat clamping jaw, or a combined structure of a cylinder and a connecting rod can also be selected to realize it. Similarly, a technical solution of using a vacuum chuck to suck the bottle body can also be selected to realize the clamping of the materials.

[0078] On the basis of the above-mentioned embodiment, a grid plate for separating the materials is provided between each row of materials.

[0079] Specifically, during the whole process, there are always grid plates between the connected materials in different columns, and the grid plates at different segmented positions are provided with chamfers to ensure a certain interval between the materials.

[0080] In this specification, the various embodiments are described in a progressive manner. The key points of each embodiment are the differences from other embodiments. The same and similar parts between the various embodiments can be referred to each other.

[0081] The above has introduced in detail an automatic pallet unloading device for BFS products applicable to four-way shuttle vehicle transfer.

The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
