Detailed Implementation

[0040] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of this utility model.

For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a connection that allows communication, a direct connection, or an indirect connection through an intermediate medium. They can also refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0043] This embodiment describes an automatic bottle sorting structure that can meet the production needs of various bottle sizes, greatly reduce bottle dropping and jamming during the boxing process, and improve boxing efficiency and stability.

[0044] like Figure 1 As shown, the bottle handling structure includes a PPU robot 1, a conveying mechanism 2, a limiting mechanism 3, a bottle pushing mechanism 4, and a flipping mechanism 5. The PPU robot 1 and the limiting mechanism 3 are respectively arranged at the input end and the output end of the conveying mechanism 2, while the bottle pushing mechanism 4 and the flipping mechanism 5 are arranged opposite each other on the left and right sides of the conveying mechanism 2.

[0045] PPU robotic arm 1 is used to precisely transfer bottles onto conveyor mechanism 2. For example... Figure 2 As shown, the PPU robot 1 includes a robot body 1.1, an end effector 1.2, and a first mounting bracket 1.3. The first mounting bracket 1.3 is located on one side of the input end of the conveying mechanism 2. The robot body 1.1 is fixedly mounted on the first mounting bracket 1.3, and the end effector 1.2 is mounted on the output end of the robot body 1.1. The end effector 1.2, driven by the robot body 1.1, picks up and transports bottles. In this embodiment, the end effector 1.2 consists of at least two vacuum suction cups. Through vacuum adsorption, at least two bottles are picked up and transported at one time, and placed at a predetermined position on the conveying mechanism 2. The transported bottles are in a state where the bottle mouth and bottle bottom are aligned, which helps to improve the efficiency of material transition and transfer, and adapts to higher production line speeds.

[0046] Conveying mechanism 2 is used to convey bottles, such as Figure 3 As shown, the conveying mechanism 2 includes a first motor 2.1, a chain conveyor device 2.2, a first guardrail 2.3, a second guardrail 2.4, a bottle-blocking device 2.5, and a second mounting bracket 2.6.

[0047] The chain conveyor 2.2 is a linear chain conveyor line, mounted on multiple second mounting brackets 2.6. The first motor 2.1 is connected to the main sprocket of the chain conveyor 2.2, providing rotational power to the chain conveyor 2.2. In this embodiment, the chain conveyor 2.2 is tilted downward at a predetermined angle along the conveying direction to ensure that the bottles can be smoothly conveyed forward (i.e., to the output end). Preferably, the predetermined angle is 5° to 10°.

[0048] At least one first guardrail 2.3 is installed across the input end of the chain conveyor 2.2 to prevent the PPU robot 1 from shifting the bottles towards the input end of the chain conveyor 2.2 after they have been transported onto it, thus ensuring the continuity of the bottle arrangement. When multiple first guardrails 2.3 are present, they are arranged parallel to each other at intervals to further reduce the risk of bottles shifting towards the input end and falling off.

[0049] Second guardrails 2.4 are installed on both sides of the chain conveyor 2.2 to prevent bottles from moving to the sides of the chain conveyor 2.2 during transport, ensuring reliable and continuous transport of the bottles. In this embodiment, the second guardrails 2.4 are liftable guardrails, which can be raised and lowered by a set of cylinders. When the second guardrails 2.4 are raised, they limit the movement of the bottles. When a bottle pushing action is performed, the second guardrails 2.4 are first lowered to below the upper surface of the chain conveyor 2.2 so that the bottles can be smoothly pushed out of the chain conveyor 2.2.

[0050] The bottle-stopping device 2.5 is arranged between the first guardrail 2.3 and the bottle-pushing mechanism 4, and includes a stop block and a support frame. The stop block is installed at a predetermined position on the chain conveyor 2.2 via the support frame, and is located above the chain conveyor 2.2. It is a liftable stop block, and the lifting method of the stop block includes, but is not limited to, lifting the stop block via a cylinder. When the stop block is lowered, it can cut off the friction between two adjacent bottles below it, ensuring that when the bottle-pushing mechanism 4 is activated, there is no frictional resistance between the pushed bottle and the bottle behind it. After the stop block is raised, the chain conveyor 2.2 can continue to move the bottle forward.

[0051] The limiting mechanism 3 works in conjunction with the bottle-blocking device 2.5 of the conveying mechanism 2 to achieve the purpose of conveying the entire row of bottles in a tight arrangement forward and controlling the relative position of the bottles.

[0052] like Figure 4As shown, the limiting mechanism 3 includes a linear module 3.1, a limiting plate 3.2, and a first mounting base 3.3. The linear module 3.1 is mounted on one side of the chain conveyor 2.2 via the first mounting base 3.3, and the linear slide rail of the linear module 3.1 is parallel to the conveying axis of the chain conveyor 2.2 between the bottle-stopping device 2.5 and the output end of the chain conveyor 2.2. The limiting plate 3.2 is slidably mounted on the linear slide rail and located above the chain conveyor 2.2. Its height matches the bottle diameter. The limiting plate 3.2 can slide along the conveying axis of the chain conveyor 2.2 under the drive of the linear module 3.1 and make close contact with the foremost bottle on the chain conveyor 2.2. In this embodiment, the initial position of the limiting plate 3.2 is the transition position between the bottle-blocking device 2.5 and the bottle-pushing mechanism 4. When the PPU robot 1 triggers the bottle-releasing signal, the limiting plate 3.2 moves one step in the conveying direction of the chain conveyor 2.2 under the drive of the linear module 3.1. When the limiting plate 3.2 moves, the bottle also moves one step forward due to the operation of the chain conveyor 2.2, so that the limiting plate 3.2 is always in contact with the foremost bottle on the chain conveyor 2.2 until the number of steps the limiting plate 3.2 moves reaches the number of bottles required for the entire row of bottles for boxing.

[0053] The bottle-pushing mechanism 4 is used to push the entire row of bottles on the chain conveyor 2.2 onto the flipping mechanism 5. For example... Figure 5 and Figure 6 As shown, the bottle pushing mechanism 4 includes a second motor 4.1, a synchronous belt drive device 4.2, a first bottle pushing plate 4.3, a second bottle pushing plate 4.4, a first cylinder 4.5, a top plate 4.6, a slider 4.7, a slide rail 4.8, a protective cover 4.9, and a second mounting base 4.10.

[0054] On the outside of the limiting mechanism 3, along the direction perpendicular to the axis of the conveying mechanism 2, the synchronous belt drive device 4.2 and two slide rails 4.8 are respectively installed on the top surface of the second mounting base 4.10, and the two slide rails 4.8 are symmetrical on both sides of the synchronous belt drive device 4.2. The second motor 4.1 is installed on the second mounting base 4.10, and the output shaft of the second motor 4.1 is connected to the synchronous belt drive device 4.2 to provide driving force for the synchronous belt drive device 4.2.

[0055] The top plate 4.6 is a hollow flat plate, with one end slidably connected to the slide rail 4.8 via two symmetrical sliders 4.7, and the other end is fitted with a bottle pusher plate. One of the sliders 4.7 is connected to one side of the synchronous belt of the synchronous belt drive device 4.2. When the second motor 4.1 drives the synchronous belt drive device 4.2 to move back and forth, the synchronous belt drives the top plate 4.6 to slide back and forth along the slide rail 4.8 via the sliders 4.7, thereby driving the bottle pusher plate to push the bottle out.

[0056] The bottle pusher consists of a first bottle pusher 4.3 and a second bottle pusher 4.4. The length of the bottle pusher is adjusted according to the number of bottles packed in each row.

[0057] The upper part of the first bottle pusher plate 4.3 is installed at the end of the top plate 4.6 and is integrated with the top plate 4.6. The lower part of the first bottle pusher plate 4.3 has a forward-extending convex plate, through which the first bottle pusher plate 4.3 contacts the bottle. In this embodiment, the first bottle pusher plate 4.3 can be composed of multiple pusher plates to adapt to the bottle handling needs of different sizes and quantities of bottles.

[0058] The second bottle pusher plate 4.4 is arranged side by side with the first bottle pusher plate 4.3 and is a flat plate with the same thickness as the convex plate. It cooperates with the first cylinder 4.5 to form a movable bottle pusher plate. The first cylinder 4.5 is installed on the upper part of one end of the first bottle pusher plate 4.3. The piston rod of the first cylinder 4.5 is connected to the second bottle pusher plate 4.4. The first cylinder 4.5 drives the second bottle pusher plate 4.4 to move up and down to adjust the overall length of the bottle pusher plate, thereby changing the number of bottles that can be pushed out. In this embodiment, in order to achieve staggered packaging of bottles, the difference in the number of bottles between two adjacent rows is one. That is, when the second bottle pusher plate 4.4 moves down to be flush with the convex plate of the first bottle pusher plate 4.3, the number of bottles pushed by the bottle pusher plate is m. When the height of the second bottle pusher plate 4.4 moves up exceeds the diameter of the bottle, the number of bottles pushed by the bottle pusher plate is m-1.

[0059] In addition, a protective cover 4.9 is installed on the top plate 4.6. The protective cover 4.9 is located above the synchronous belt drive device 4.2, which can prevent debris from falling into the synchronous belt drive device 4.2 and reduce the impact on the reliability of the bottle pushing action of the bottle handling structure.

[0060] The flipping mechanism 5 is arranged on the side opposite to the bottle pushing mechanism 4 of the chain conveyor 2.2, and is used to stand up the row of bottles pushed out by the bottle pushing mechanism 4 to prepare for subsequent boxing.

[0061] like Figure 7 As shown, the flipping mechanism 5 includes a third motor 5.1, a right-angle plate 5.2, a first baffle 5.3, a second cylinder 5.4, a third mounting bracket 5.5, and a second baffle 5.6.

[0062] Each of the two third mounting brackets 5.5 is equipped with a bearing, and the two bearings are arranged coaxially. One end of the right-angle plate 5.2 is mounted in the bearing on one of the third mounting brackets 5.5 via a rotating shaft, and the other end of the right-angle plate 5.2 passes through the bearing on the other third mounting bracket 5.5 via a rotating shaft and is connected to the output shaft of the third motor 5.1. The third motor 5.1 is fixed to the outside of the third mounting bracket 5.5. The right-angle plate 5.2 can rotate on the third mounting bracket 5.5 under the drive of the third motor 5.1.

[0063] A first baffle 5.3 and a second baffle 5.6 are respectively arranged at both ends of the upper surface of the right-angle plate 5.2, and at least one baffle is a movable baffle. This embodiment takes the first baffle 5.3 as a movable baffle as an example for explanation.

[0064] The second cylinder 5.4 and the second baffle 5.6 are respectively mounted on both ends of the upper surface of the right-angle plate 5.2. The piston rod of the second cylinder 5.4 is connected to the first baffle 5.3. The second baffle 5.6 is fixedly mounted on the right-angle plate 5.2, serving as a fixed baffle. The second cylinder 5.4 can change the distance between the first baffle 5.3 and the second baffle 5.6 by pushing and pulling the first baffle 5.3 on the right-angle plate 5.2. When the number of bottles pushed is small, the second cylinder 5.4 pushes the first baffle 5.3 forward to a predetermined position; when the number of bottles pushed is large, the second cylinder 5.4 drives the first baffle 5.3 backward to a predetermined position.

[0065] In this embodiment of the automatic bottle-scraping structure, the PPU robot arm 1 is located at the output end of the bottle detection device, and its operation process is as follows:

[0066] 1. The testing equipment moves the qualified bottles to the output end to wait for bottle sorting. The limit plate 3.2 moves to the predetermined initial position. Bottles are manually placed between the limit plate 3.2 and the bottle placement position of the PPU robot 1 (located in front of the first guardrail 2.3). The limit plate 3.2 connects with the foremost bottle. At this time, the stop block of the bottle blocking device 2.5 rises to the high position. The conveying mechanism 2 is started. The bottles do not move under the obstruction of the stop block.

[0067] 2. The PPU robot 1 picks up two bottles at a time via the end effector 1.2 and transports them to the bottle placement position on the chain conveyor 2.2. At the same time, the linear module 3.1 moves the limit plate 3.2 forward one step as the PPU robot 1 places the bottles, based on the bottle placement action signal of the PPU robot 1. The bottles on the chain conveyor 2.2 move forward one step as a whole, following the limit plate 3.2, under the conveying of the chain conveyor 2.2 and the squeezing of the bottles placed by the PPU robot 1. This process ensures that the entire row of bottles moves as a whole in close contact.

[0068] 3. Repeat the bottle picking and placing actions of PPU robot 1 in step 2 until the limit plate 3.2 moves forward to the set end position a (this position is determined according to the number of bottles per row required for boxing, and the number of bottles per row is the number of bottles between the limit plate 3.2 and the bottle blocking device 2.5). At this time, the bottle blocking device 2.5 controls the block to descend, blocking all bottles after it from continuing to be conveyed, while only a predetermined number of bottles are retained in front of the bottle blocking device 2.5.

[0069] 4. The second guardrail 2.4 is lowered to a predetermined height so that its upper surface is not higher than the upper surface of the chain conveyor device 2.2;

[0070] 5. Based on the number m of bottles between the limiting plate 3.2 and the bottle-blocking device 2.5 at this time, control the second bottle-pushing plate 4.4 to descend until it is flush with the first bottle-pushing plate 4.3; at the same time, the second cylinder 5.4 drives the first baffle 5.3 to retract a predetermined stroke, so that the distance between the first baffle 5.3 and the second baffle 5.6 matches the distance between the limiting plate 3.2 and the bottle-blocking device 2.5;

[0071] 6. The synchronous belt drive device 4.2 drives the bottle pusher plate forward through the top plate 4.6, pushing the entire row of bottles between the limiting plate 3.2 and the bottle blocking device 2.5 onto the right-angle plate 5.2;

[0072] 7. The third motor 5.1 drives the right-angle plate 5.2 to rotate to a certain angle, standing up the row of bottles on the right-angle plate 5.2, ready for subsequent boxing; at the same time, the bottle pusher returns to the starting position, and the limit plate 3.2 moves to the initial position, ready for the next bottle sorting process;

[0073] 8. Move the limiting plate 3.2 forward to the end position b as in step 3, where end position b = end position a - bottle diameter D; the number of bottles between the limiting plate 3.2 and the bottle-stopping device 2.5 is m-1, and repeat steps 2 to 7.

[0074] In step 5, based on the number of bottles between the limiting plate 3.2 and the bottle-blocking device 2.5 being m-1, the first cylinder 4.5 drives the second bottle-pushing plate 4.4 to rise by a predetermined stroke, without participating in the bottle-pushing action; at the same time, the second cylinder 5.4 pushes the first baffle 5.3 to extend by a predetermined stroke, so that the distance between the first baffle 5.3 and the second baffle 5.6 is reduced by one bottle diameter.

[0075] 9. Repeat steps 2 to 8 twice to complete the bottle sorting process until the bottle sorting operation is finished, thus achieving the spaced sorting of two rows of bottles with different numbers of bottles.

[0076] Although the principles of this utility model have been described in detail above with reference to preferred embodiments, those skilled in the art should understand that the above embodiments are merely illustrative explanations of the implementation of this utility model and are not intended to limit the scope of this utility model. The details in the embodiments do not constitute a limitation on the scope of this utility model. Any obvious changes, such as equivalent transformations or simple substitutions, based on the technical solution of this utility model without departing from its spirit and scope fall within the protection scope of this utility model.
