Description

Technical Field

[0001] This utility model relates to the field of milk packaging technology, specifically an automatic milk packaging device. Background Technology

[0002] In the milk processing industry, packaging boxed or bagged milk is a crucial step before the product leaves the factory. Among these steps, evenly stacking the milk products into the packaging box and sealing it directly affects the safety of the product during transportation and its appearance.

[0003] Currently, the industry generally uses automated production lines to complete the above-mentioned stacking operations. The specific process is as follows: individual milk cartons or milk bags are continuously transported to the stacking station via a conveyor belt, and then a robotic arm is used to pick them up at the station and place them into the corresponding packaging boxes in sequence. Finally, after sealing, they enter the sales stage.

[0004] However, the existing stacking method has obvious drawbacks: on the one hand, the robotic arm can only pick up one milk carton or milk bag at a time, and the amount of material transferred in a single operation is limited, resulting in low overall stacking efficiency and difficulty in meeting the high-efficiency requirements of large-scale production; on the other hand, since individual milk cartons or milk bags need to be placed into different positions in the packaging box in sequence, the robotic arm needs to frequently adjust its spatial position to match the target stacking position in the packaging box during the repeated picking and placing movements. This places extremely high demands on the complexity of the control program, which not only increases the investment cost of equipment debugging and program development in the early stage, but also makes it easier to troubleshoot faults during the later equipment maintenance process, further increasing the maintenance cost of production.

[0005] Therefore, optimizing the equipment structure and operation methods in the milk stacking process to improve stacking efficiency and reduce production costs has become a pressing technical problem in this field. Utility Model Content

[0006] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides an automatic milk packaging device. The packaging device uses a first conveyor belt and a second conveyor belt to separately transport packaged milk and packaging boxes. Combined with a stacking mechanism and a movable and lifting vacuum adsorption mechanism, it can not only automatically stack the packaged milk during the transportation process, but also adsorb it into the packaging box after stacking through the movable and lifting vacuum adsorption mechanism. This method not only improves packaging efficiency, but also eliminates the need for a robotic arm structure, reducing the investment cost before production and the maintenance cost afterward.

[0007] This invention is achieved by constructing an automatic milk packaging device, including a first conveyor belt for uniformly conveying packaged milk.

[0008] The second conveyor belt transports the opened packaging boxes.

[0009] The vacuum adsorption mechanism is set above the discharge end of the first and second conveyor belts by a frame and maintains linear movement and lifting. The packaged milk conveyed on the first conveyor belt is adsorbed into the packaging box by the linear movement and lifting of the vacuum adsorption mechanism.

[0010] The stacking mechanism is set on the discharge end of the first conveyor belt to evenly stack packaged milk.

[0011] Preferably, the frame is provided with a slide rail, which spans above the discharge ends of the first and second conveyor belts. The vacuum adsorption mechanism is mounted on the slide rail and slides linearly along the slide rail. A first linear telescopic device is provided on the outer side of any end of the slide rail. The movable end of the first linear telescopic device is connected to the side of the vacuum adsorption mechanism to drive the vacuum adsorption mechanism to move linearly or be fixed.

[0012] Preferably, the vacuum adsorption mechanism includes,

[0013] The support plate has four sliding blocks at its bottom corners that match the slide rails.

[0014] The mounting plate is positioned parallel to the support plate via guide columns and is kept moving up and down.

[0015] Several vacuum suction cups are evenly arranged on the bottom of the mounting plate and controlled by an external vacuum adsorption source;

[0016] Two vertical plates are fixed above the support plate;

[0017] Two sprockets are rotatably mounted at the bottom and top between the gaps of the two vertical plates;

[0018] The chain is tensioned between the two sprockets;

[0019] The transmission plate is fixed to any link of the chain and its bottom passes through the support plate and is fixed to the mounting plate.

[0020] The drive motor is fixed to the outside of any vertical plate and drives any sprocket to rotate.

[0021] Preferably, the stacking mechanism includes,

[0022] The stacking tray is fixed between the discharge ends of the first and second conveyor belts;

[0023] The first baffle is fixed on the stacking tray and its open end faces the first conveyor belt;

[0024] The second baffle is fixed to the first conveyor belt to block the packaged milk being transported;

[0025] The third baffle, which is movably installed on the second baffle, pushes the packaged milk that is blocked at the position of the second baffle onto the stacking tray.

[0026] Preferably, the first baffle is C-shaped with its open end pointing towards the first conveyor belt. The second and third baffles are both L-shaped. One end of the second baffle is fixed to the frame on the side of the first conveyor belt away from the stacking tray, and the other end extends above the first conveyor belt and near the discharge end. A second linear telescopic device is provided on the end of the second baffle that is fixed to the frame. The telescopic end of the second linear telescopic device passes through the second baffle and points towards the stacking tray. One end of the third baffle is parallel to the inner side of the end of the second baffle that is fixed to the frame and is fixed to the telescopic end of the second linear telescopic device. The other end of the third baffle is located on the side away from the stacking tray and the discharge end of the first conveyor belt.

[0027] Preferably, side baffles are provided on the sides of both the first conveyor belt and the second conveyor belt.

[0028] This utility model has the following beneficial effects:

[0029] This packaging device achieves synchronous flow of packaged milk and cartons through independent conveying via a first and second conveyor belt, avoiding the waiting issues associated with traditional single-conveyor lines. Simultaneously, the stacking mechanism can evenly stack the packaged milk during transport, and combined with a vacuum adsorption mechanism, it can transfer multiple stacked milk cartons at once, replacing the single-take operation of a robotic arm. This significantly shortens the stacking cycle for a single carton of milk and adapts to the needs of large-scale continuous production.

[0030] Meanwhile, this packaging device eliminates the complex mechanical structure and precision control components of traditional robotic arms, reducing upfront costs for equipment procurement and program development. The movement and lifting actions of the vacuum adsorption mechanism are achieved through simplified drive components, resulting in simpler control logic and reduced difficulty in troubleshooting during later maintenance. This reduces maintenance time and spare parts replacement costs, leading to significant long-term operating cost advantages. Attached Figure Description

[0039] As described in the background section, in existing milk processing, robotic arms are typically used to grip and pack packaged milk (boxed or bagged milk) while it is being transported. This method is inefficient, as it can only grip and pack one package of milk at a time. Furthermore, the robotic arms require complex procedures to automate the operation after installation, which not only requires significant upfront investment but also presents challenges for subsequent maintenance, resulting in high costs.

[0040] For the reasons stated above, please refer to the appendix. Figure 1 This utility model provides an automatic milk packaging device, including a first conveyor belt 1 for uniformly conveying packaged milk;

[0041] The second conveyor belt 2 transports the packaging boxes with their openings open.

[0042] The vacuum adsorption mechanism 5 is set above the discharge end of the first conveyor belt 1 and the second conveyor belt 2 via the frame 4 and maintains linear movement and lifting. The vacuum adsorption mechanism 5 adsorbs the packaged milk conveyed on the first conveyor belt 1 into the packaging box through the linear movement and lifting of the vacuum adsorption mechanism 5.

[0043] The stacking mechanism is set on the discharge end of the first conveyor belt 1 to evenly stack packaged milk.

[0044] Please see the appendix Figure 2 To facilitate the linear movement of the vacuum adsorption mechanism, thereby adsorbing and moving the packaged milk conveyed on the first conveyor belt into the packaging box on the second conveyor belt, in this embodiment, a slide rail 6 is provided on the frame 4. The slide rail 6 spans above the discharge ends of the first conveyor belt 1 and the second conveyor belt 2. The vacuum adsorption mechanism 5 is installed on the slide rail 6 and slides linearly along the direction of the slide rail 6. A first linear telescopic device 7 is provided on the outer side of any end of the slide rail 6. The movable end of the first linear telescopic device 7 is connected to the side of the vacuum adsorption mechanism 5 to drive the vacuum adsorption mechanism 5 to move linearly or be fixed.

[0045] Please see the appendix Figure 3 To achieve automatic adsorption and movement of packaged milk, in this embodiment, the vacuum adsorption mechanism 5 includes,

[0046] The support plate 501 has four sliding blocks 502 at its bottom corners that match the slide rail 6;

[0047] Mounting plate 503 is installed parallel to the support plate 501 via guide post 505 and is kept moving up and down;

[0048] Several vacuum suction cups 504 are evenly arranged on the bottom of the mounting plate 503 and controlled by an external vacuum adsorption source;

[0049] Two vertical plates 506 are fixed above the support plate 501;

[0050] Two sprockets 507 are rotatably mounted at the bottom and top between the gaps of the two vertical plates 506;

[0051] Chain 508 is tensioned between two sprockets 507;

[0052] The transmission plate 509 is fixed to any link of the chain 508 and its bottom passes through the support plate 501 and is fixed to the mounting plate 503.

[0053] The drive motor 510 is fixed to the outside of any vertical plate 506 and drives any sprocket 507 to rotate.

[0054] Please see the appendix Figure 4To achieve automatic stacking of packaged milk on the first conveyor belt, in this embodiment, the stacking mechanism includes:

[0055] The stacking tray 8 is fixed between the discharge ends of the first conveyor belt 1 and the second conveyor belt 2;

[0056] The first baffle 9 is fixed on the stacking tray 8 and its open end faces the first conveyor belt 1;

[0057] The second baffle 10 is fixed to the first conveyor belt 1 to block the packaged milk being conveyed.

[0058] The third baffle 12 is movably installed on the second baffle 10 to push the packaged milk blocked at the position of the second baffle 10 onto the stacking tray 8.

[0059] Please refer to the appendix again. Figure 4 To facilitate pushing the stacked packaged milk onto the stacking tray and waiting for the vacuum adsorption mechanism to adsorb and move it into the packaging box of the second conveyor belt, and to prevent subsequent packaged milk from being conveyed into the gap between the second and third baffles during the pushing process, in this embodiment, the first baffle 9 is C-shaped with its open end pointing towards the first conveyor belt 1, and the second baffle 10 and the third baffle 12 are both L-shaped baffles. One end of the second baffle 10 is fixed to the frame on the side of the first conveyor belt 1 away from the stacking tray 8, and the other end extends above the first conveyor belt 1 and near the discharge end. A second linear telescopic device 11 is provided on the end of the second baffle 10 fixed to the frame. The telescopic end of the second linear telescopic device 11 passes through the second baffle 10 and points towards the stacking tray 8. One end of the third baffle 12 is arranged parallel to the inner side of the end of the second baffle 10 fixed to the frame and is fixed to the telescopic end of the second linear telescopic device 11. The other end of the third baffle 12 is located on the side away from the stacking tray 8 and the discharge end of the first conveyor belt 1.

[0060] During the stacking process, the second linear telescopic device first retracts, causing one end of the third baffle 12 to fit against one end of the second baffle 10. The packaged milk conveyed on the first conveyor belt 1 is then transported to the other end of the second baffle 10 and fixed. Subsequent packaged milk can be stacked sequentially. After a certain period of time, the second linear telescopic device extends, causing the third baffle 12 to extend as well. During the extension process, the third baffle 12 pushes the packaged milk stacked on the first conveyor belt 1 to move onto the stacking tray 8. At the same time, the other end of the third baffle 12 prevents the subsequent packaged milk conveyed on the first conveyor belt 1 from entering the gap between the third baffle and the second baffle. This protects the packaged milk and prevents the milk in the gap from being crushed when one end of the third baffle 12 approaches the second baffle after the second linear telescopic device retracts.

[0061] Please see the appendix Figure 1To ensure smooth transport of packaged milk and packaging boxes, in this embodiment, side baffles 3 are provided on the sides of both the first conveyor belt 1 and the second conveyor belt 2.

[0062] In this embodiment, both the first linear telescopic device and the second linear telescopic device are telescopic cylinders or electronic push rods, which facilitates automatic control.

[0063] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
