Description

Technical Field

[0001] This utility model relates to the field of bottle unloading machine technology, specifically to a push hook tray dispensing mechanism. Background Technology

[0002] On bottle-unloading production lines in the food and pharmaceutical industries, empty trays after bottle unloading need to be promptly transferred to trolleys for recycling. Traditionally, this process relies entirely on manual operation, which has several drawbacks: operators must be present throughout the entire process, manually adjusting the lifting platform to the corresponding height on the trolley, then manually starting the conveyor to move the empty trays towards the trolley. When a tray partially leaves the edge of the conveyor, the operator must manually pull it back into the trolley. After each layer is pushed, the process of adjusting the height, starting the conveyor, and manually pulling the tray is repeated until the trolley is full. This manual operation method has significant shortcomings: 1. Extremely low efficiency: A single cart requires multiple manual interventions to be fully loaded, the operation is cumbersome and cannot match the high-speed cycle of an automated production line; 2. High labor intensity: Operators need to frequently bend over and reach out to pull the trays, which can easily lead to fatigue injuries over a long period of time; 3. High cost: It requires dedicated personnel to operate, resulting in a high proportion of labor costs, and it is difficult to achieve simultaneous monitoring of multiple lines. 4. Poor stability: Uneven manual pulling force can easily cause the tray to tilt, jam, or even damage materials or equipment; 5. Hygiene risks: The food and pharmaceutical industries have high requirements for the cleanliness of the production environment, and human contact can easily cause contamination risks. Summary of the Invention

[0003] The purpose of this utility model is to provide a push-hook tray ejection mechanism that solves the cumbersome process of "manually adjusting height, manually starting the conveyor, and manually pulling the tray" in traditional manual operation, realizing fully automated operation from tray conveying to pushing into the trolley, improving production efficiency, reducing labor costs, and reducing pollution risks. To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0004] A push-hook tray dispensing mechanism, characterized in that it includes a tray conveying mechanism, a push-hook mounting frame installed on the tray conveying mechanism, and a push-hook tray dispensing mechanism installed on the lower side of the push-hook mounting frame; The tray conveying mechanism includes a stainless steel frame, a drive shaft assembly, two sets of drive chain assemblies, two sets of guardrail assemblies, and a drive motor. The stainless steel frame is welded from stainless steel rectangular tubes, and mounting plates for mounting push hook mounting frames are welded on both sides. The drive shaft assembly and drive motor are installed on the tray outlet side of the stainless steel frame. The drive chain assembly consists of chains and sprockets, with two sets installed on both sides of the stainless steel frame. The two sets of guardrail assemblies are installed on both sides of the stainless steel frame, and one set of guardrail assemblies is provided with a first detection switch, a second detection switch, and a third detection switch in sequence from the tray inlet side to the tray outlet side. The push hook mounting frame is a frame structure made of aluminum profiles connected by bolts, and is mounted on a stainless steel frame mounting plate. The push-hook tray ejection mechanism includes a rodless cylinder, a push-hook mounting plate, and two sets of push-hook assemblies. The rodless cylinder is installed on the lower side of the push-hook mounting frame, and the push-hook mounting plate is installed perpendicularly to the rodless cylinder. The two sets of push-hook assemblies are respectively installed on both sides of the long side of the push-hook mounting plate. Each push-hook assembly includes a push-hook fixing component, a pin, and a push-hook. The push-hook is installed on the push-hook fixing component via the pin. A limit block is welded to the push-hook fixing component, which restricts the push-hook to rotate only towards the tray ejection side. When the push-hook is in a free state, its minimum height is lower than the height of the tray box.

[0005] Furthermore, the push-hook ejection mechanism is characterized in that the push-hook mounting plate is made of aluminum 6061.

[0006] Furthermore, the push hook ejection mechanism is characterized in that: the push hook fixing component, the pin shaft, and the push hook are all made of stainless steel.

[0007] Furthermore, the aforementioned push-hook tray ejection mechanism is characterized in that: the guardrail assembly is used to guide and limit the tray box, ensuring that the tray box is transported along a preset path and accurately enters the corresponding layer of the trolley.

[0008] Furthermore, the aforementioned push-hook tray ejection mechanism is characterized in that: the first detection switch is used to detect whether the feedback tray has entered the tray conveying mechanism, the second detection switch is used to detect whether the feedback tray has completely entered or left the tray conveying mechanism, and the third detection switch is used to detect the positioning status of the feedback trolley.

[0009] Compared with the prior art, the advantages of this utility model are: High degree of automation: No manual intervention is required for height adjustment, conveyor start-up, and tray pulling. The fully automatic operation from tray entry to complete push-in of the trolley is achieved through the linkage of detection switches and actuators.

[0010] Reduce labor intensity: Completely replace repetitive actions such as bending over and reaching out, reducing the risk of fatigue injury to operators. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0018] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0020] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0023] like Figures 1-6As shown, a push-hook tray ejection mechanism includes a tray conveying mechanism 1, a push-hook mounting frame 2 mounted on the tray conveying mechanism 1, and a push-hook tray ejection mechanism 3 mounted on the lower side of the push-hook mounting frame 2. The tray conveying mechanism 1 includes a stainless steel frame 11, a drive shaft assembly 12, two sets of drive chain assemblies 13, two sets of guardrail assemblies 14, and a drive motor 15. The stainless steel frame 11 is welded from stainless steel rectangular tubing, and mounting plates for mounting the push-hook mounting frame 2 are welded to both sides. The drive shaft assembly 12 and the drive motor 15 are mounted on the tray ejection side of the stainless steel frame 11. The drive chain assemblies 13 consist of chains and sprockets, with two sets respectively mounted on both sides of the stainless steel frame 11. The two sets of guardrail assemblies 14 are respectively mounted on both sides of the stainless steel frame 11, and one set of guardrail assemblies 14 has a first detection switch, a second detection switch, and a third detection switch sequentially arranged from the tray inlet side to the tray outlet side. The push-hook mounting frame 2 is a frame structure made of aluminum profiles connected by bolts, mounted on the mounting plate of the stainless steel frame 11. The push hook dispensing mechanism 3 includes a rodless cylinder 31, a push hook mounting plate 32, and two sets of push hook assemblies 33. The rodless cylinder 31 is installed on the lower side of the push hook mounting frame 2. The push hook mounting plate 32 is installed perpendicularly to the rodless cylinder 31. The two sets of push hook assemblies 33 are respectively installed on both sides of the long side of the push hook mounting plate 32. The push hook assembly 33 includes a push hook fixing part 331, a pin 332, and a push hook 333. The push hook 333 is installed on the push hook fixing part 331 through the pin 332. A limit block is welded on the push hook fixing part 331. The limit block restricts the push hook 333 to rotate only towards the dispensing side. When the push hook 333 is in a free state, its minimum height is lower than the height of the disc box 4.

[0024] The following describes the workflow of this utility model in detail, using a bottle unloading machine as an example in a production scenario (requires the use of a lifting platform 6 and a PLC control system): Initial state: The rodless cylinder 31 drives the push hook mounting plate 32 to the tray inlet side of the tray conveying mechanism 1, the push hook 333 is in a free hanging state, the lifting platform 6 is in the initial low position, and the drive motor 15 is in the stopped state.

[0025] Tray box entry detection: Empty tray box 4 is conveyed from the bottle unloading machine at the previous station to the tray box conveying mechanism 1. When the first detection switch of the guardrail assembly 14 detects tray box 4, it sends a signal to the control system. The control system starts the drive motor 15, which drives the chains of the two sets of transmission chain assemblies 13 through the transmission shaft assembly 12 to transport tray box 4 to the tray exit side. At this time, tray box 4 contacts push hook 333. Push hook 333 rotates around pin 332 to the tray exit side under the pushing force of tray box 4, so as not to hinder the progress of tray box 4.

[0026] Disk box positioning stop: When the disk box 4 is fully entered into the disk box conveying mechanism 1 and the second detection switch is triggered, the second detection switch sends a signal to the control system, the control system immediately stops the drive motor 15, the transmission chain assembly 13 stops running, and the disk box 4 is in the push-out position.

[0027] Trolley positioning and lifting adjustment: After the third detection switch of the guardrail assembly 14 detects that the trolley 5 has reached the designated position, it sends a signal to the control system. The control system starts the lifting platform 6 and synchronously lifts the tray conveying mechanism 1 and the tray 4 to the corresponding height of the current loading layer of the trolley 5. After the lifting is in place, the lifting platform 6 stops.

[0028] Collaborative Push: The control system first starts the drive motor 15 to make the transmission chain assembly 13 run. After a preset time delay (ensuring that the end of the disc box 4 exceeds the push hook 333), the rodless cylinder 31 is started. The rodless cylinder 31 drives the push hook mounting plate 32 to move towards the disc exit side. The push hook 333 remains vertical under the restriction of the limit block. Together with the transmission chain assembly 13, it smoothly pushes the disc box 4 into the corresponding layer of the trolley 5. The disc box can be completely entered into the trolley without manual pulling.

[0029] Reset cycle: When the second detection switch detects that the tray 4 has completely left the tray conveying mechanism 1, it sends a signal to the control system. The control system stops the drive motor 15 and simultaneously controls the rodless cylinder 31 to drive the push hook mounting plate 32 back to the tray inlet side. The lifting platform 6 descends to the initial position and waits for the next tray 4 to enter. The above process is repeated until each layer of the trolley 5 is full.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
