[0036] Reference Figure 1 、 Figure 4 and Figure 5 According to an embodiment of the present application, the stacking device includes: a feeding mechanism 100, a stacking mechanism 200, a first pushing mechanism 400 and a second pushing mechanism 500.

[0037] The feeding mechanism 100 is formed with a feeding channel 110, and the feeding mechanism 100 is used to transport the products 700 in the feeding channel 110; the stacking mechanism 200 is formed with a stacking channel 220, and the feeding end 230 of the stacking channel 220 is located next to the feeding channel 110; the pushing mechanism 300 is located on one side of the feeding channel 110, and is used to push the products 700 in the feeding mechanism 100 to the feeding end 230 of the stacking channel 220; the first pushing mechanism 400 includes a first pushing part 410, a first pushing driving part 420 and a first avoiding driving part 430, the first avoiding driving part 430 drives the first pushing part 410 to drive the first pushing part 410 in and out of the stacking channel 220, and the first pushing driving part 420 drives the first pushing part 410 to be connected to the first pushing part The first pushing part 410 is driven to move along the stacking channel 220 so that the first pushing part 410 pushes the product 700 at the inlet end 230 of the stacking channel 220 to the outlet end 240 of the stacking channel 220; the second pushing mechanism 500 includes a second pushing part 510, a second pushing driving part 520 and a second avoidance driving part 530, the second avoidance driving part 530 drives and connects the second pushing part 510, and is used to drive the second pushing part 510 to enter and exit the stacking channel 220, the second pushing driving part 520 drives and connects the second pushing part 510, and is used to drive the second pushing part 510 to move along the stacking channel 220 and pass through the stacking channel 220, so that the second pushing part 510 pushes the product 700 at the outlet end 240 of the stacking channel 220 out of the stacking channel 220.

[0038] It can be understood that the feeding mechanism 100 conveys the products 700 in the feeding channel 110 to the side of the pushing mechanism 300, and the pushing mechanism 300 pushes the products 700 in the feeding channel 110 one by one to the inlet end 230 of the stacking channel 220, so that the products 700 continuously enter the stacking channel 220, so that the products 700 are stacked in the stacking channel 220. In the initial state, the first pushing part 410 and the second pushing part 510 are located outside the stacking channel 220 to avoid interfering with the products 700 entering the stacking channel 220, and the first pushing part 410 is located beside the inlet end 230. After a certain number of products 700 are stacked in the stacking channel 220, the first avoidance driving part 430 drives the first pushing part 410 to enter the stacking channel 220, so that the first pushing part 410 is located in the stacking channel 220 close to the products 700. Near one side of the ejection mechanism 300, the first pushing drive unit 420 then drives the first pushing unit 410 to move along the stacking channel 220 to allow the product 700 at the inlet end 230 to be pushed to the outlet end 240. It should be understood that the products 700 are stacked to a certain length. When the products 700 at the inlet end 230 are pushed to the outlet end 240, part of the stacked products 700 are pushed out of the stacking channel 220, while part of the products 700 remain in the stacking channel 220. After the products 700 at the inlet end 230 are pushed to the outlet end 240, the first avoidance drive unit 430 drives the first pushing unit 410 to leave the stacking channel 220 to avoid interfering with the movement of the second pushing unit 510. At the same time, the first pushing drive unit 420 drives the first pushing unit 410 to return to its original position. Then, the second avoidance drive unit 530 drives the second pushing unit 510 to enter the stacking channel 220 and locate at the side of the product 700 in the stacking channel 220 close to the ejection mechanism 300. Then, the second pushing drive unit 520 drives the second pushing unit 510 to move along the stacking channel 220 and pass through the stacking channel 220. The second pushing unit 510 pushes the product 700 at the discharge end 240 out of the stacking channel 220, thereby pushing out all the products 700 in the stacking channel 220 to avoid affecting the stacking of subsequent products 700. After the second pushing unit 510 pushes all the products 700 in the stacking channel 220, the second avoidance drive unit 530 and the second pushing drive unit 520 can drive the second pushing unit 510 to return to its original position.Therefore, the stacking device of the present application can transport the products 700 in the feed channel 110 to the feed end 230 of the stacking channel 220 through the pushing mechanism 300, so that the products 700 can be stacked in the stacking channel 220, and then the first pushing drive part 420 cooperates with the first pushing part 410 to push the products 700 at the feed end 230 of the stacking channel 220 to the discharge end 240 of the stacking channel 220 to push out the partially stacked products 700, and then the second pushing drive part 520 cooperates with the second pushing part 510 to push out the products 700 at the discharge end 240 of the stacking channel 220 to push out all the products 700 in the stacking channel 220. In addition, through the cooperation of the first avoidance drive part 430 and the first pushing part 410, the pushing mechanism 300 can be avoided from pushing the product 700 into the stacking channel 220. Through the cooperation of the second avoidance drive part 530 and the second pushing part 510, the pushing mechanism 300 can be avoided from pushing the product 700 into the stacking channel 220, and at the same time, the pushing action of the first pushing part 410 can be avoided, so that the stacking process and the pushing process of the product 700 are orderly, and the actions between the pushing mechanism 300, the first pushing part 410 and the second pushing part 510 do not affect each other, so that the stacking process and the pushing process of the product 700 are continuous.

[0039] Specifically, product 700 is a paper-plastic product, such as a cup lid, a paper cup, or a lunch box.

[0040] Specifically, the first pusher mechanism 400 is located below the stacking channel 220. The first avoidance drive unit 430 is a lifting cylinder that drives the first pusher unit 410 up and down to allow the first pusher unit 410 to enter and exit the stacking channel 220. The first pusher unit 420 is a synchronous belt linear module that drives the first avoidance drive unit 430 to move horizontally along the length of the stacking channel 220, thereby driving the first pusher unit 410 to move horizontally, thereby allowing the first pusher unit 410 to push the products 700 within the stacking channel 220.

[0041] Specifically, the second pushing mechanism 500 is located above the stacking channel 220. The second avoidance drive unit 530 is a lifting cylinder that drives the second pushing unit 510 up and down to allow the second pushing unit 510 to enter and exit the stacking channel 220. The second pushing drive unit 520 is a synchronous belt linear module that drives the second avoidance drive unit 530 to move horizontally along the length of the stacking channel 220, thereby driving the second pushing unit 510 to move horizontally, thereby allowing the second pushing unit 510 to push the products 700 within the stacking channel 220.

[0042] In order to prevent the second pushing portion 510 from interfering with the pushing process of the pushing mechanism 300 during the pushing process, Figure 4A side of the second pushing portion 510 close to the feeding end 230 forms an avoidance position 511 .

[0043] It can be understood that after the second pushing part 510 enters the stacking channel 220, the avoidance position 511 can avoid the product 700 pushed from the feed channel 110 to the feeding end 230 of the stacking channel 220 by the pushing mechanism 300, so that the pushing process of the second pushing part 510 does not affect the normal pushing of the pushing mechanism 300, thereby ensuring the smooth transmission of the product 700.

[0044] It should be noted that, in some embodiments, the packaging machine is arranged behind the stacking channel 220, and the product 700 needs to be pushed into the packaging machine by the second pushing portion 510. It should be understood that there is a certain distance between the stacking channel 220 and the packaging machine. Therefore, even if the stacked products 700 are pushed out from the stacking channel 220, it is still not guaranteed that they can completely enter the packaging machine. The second avoidance drive portion 530 has a certain volume and is difficult to enter the packaging machine, which affects the pushing stroke of the second pushing portion 510. In order to ensure that the second pushing portion 510 can push the stacked products 700 into the packaging machine, refer to Figure 4 The second pushing portion 510 extends along the length direction of the stacking channel 220 .

[0045] It can be understood that the second pushing portion 510 extends along the length direction of the stacking channel 220 so that the second pushing portion 510 has a certain length. Thus, when the second pushing drive portion 520 drives the second pushing portion 510 to push the product 700 at the discharge end 240 of the stacking channel 220, the second pushing drive portion 520 can drive the second pushing portion 510 to pass through the stacking channel 220, allowing the second pushing portion 510 to move toward the packaging machine at the rear, so that the second pushing portion 510 partially enters the packaging machine to ensure that the stacked products 700 are completely pushed from the stacking channel 220 into the packaging machine.

[0046] It should be noted that the product 700 is generally in a flat position after being produced by the mold, and in order to facilitate stacking, it is generally necessary to rotate the product 700 to stand upright. Therefore, in this embodiment, referring to Figure 1 and Figure 2 The feeding channel 110 is arc-shaped, and the feeding mechanism 100 is provided with a discharge port 120 connected to the feeding channel 110. The discharge port 120 is used to discharge the product 700. The discharge port 120 is opposite to the feeding end 230 of the stacking channel 220, and the tangent line of the feeding channel 110 corresponding to the discharge port 120 is along the vertical direction.

[0047] It can be understood that the feed port 130 of the feed channel 110 is used to receive the flat product 700, and the product 700 moves along the length direction of the feed channel 110. Since the feed channel 110 is arc-shaped and the tangent of the feed channel 110 corresponding to the discharge port 120 is along the vertical direction, when the product 700 reaches the position corresponding to the discharge port 120, the product 700 is in an upright posture, and the pushing mechanism 300 can push the upright product 700 out of the feed channel 110 from the discharge port 120.

[0048] Regarding the installation form of the ejector mechanism 300, refer to Figure 2 and Figure 3 The feeding mechanism 100 is provided with a top material port 140 connected to the feeding channel 110. The top material port 140 is opposite to the discharge port 120. The top material mechanism 300 includes a top material portion 310 and a top material driving portion 320. The top material driving portion 320 is arranged inside the feeding mechanism 100. The top material driving portion 320 drives the top material portion 310 to drive the top material portion 310 through the top material port 140 to enter and exit the feeding channel 110.

[0049] It can be understood that the top material driving part 320 is arranged in the feeding mechanism 100 to save the space occupied by the top material mechanism 300. The top material driving part 320 drives the top material part 310 so that the top material part 310 can enter and exit the feeding channel 110 through the top material port 140, and the top material port 140 and the discharge port 120 are opposite to each other. After the top material part 310 enters the feeding channel 110, the product 700 can be pushed out of the feeding channel 110. The top material part 310 leaves the feeding channel 110 and enters the feeding mechanism 100 to avoid the transportation of the product 700 in the feeding channel 110.

[0050] In some other embodiments, the material pushing driving unit 320 may also be disposed beside the material feeding mechanism 100 .

[0051] It should be noted that there is a certain distance between the discharge port 120 of the feed channel 110 and the feed port 130 of the stacking channel 220. Therefore, when the product 700 in the feed channel 110 reaches the position corresponding to the discharge port 120, and in the process of the pushing mechanism 300 pushing the product 700 from the feed channel 110 to the stacking channel 220, the product 700 is at risk of tipping over toward the stacking channel 220. Therefore, in order to prevent the product 700 from tipping over, the stacking device of the present application also includes a blowing mechanism (not shown in the figure), and the air outlet of the blowing mechanism is facing the discharge port 120.

[0052] It can be understood that the blowing mechanism blows air toward the discharge port 120 of the feed channel 110 to give the product 700 a force toward the feed channel 110, thereby reducing the risk of the product 700 tipping toward the stacking channel 220 and ensuring the stability of the product 700 transportation.

[0053] It should be noted that, since the feeding channel 110 is arc-shaped and the tangent line of the feeding channel 110 corresponding to the discharge port 120 is in the vertical direction, the product 700 near the discharge port 120 will be stacked above the product 700 corresponding to the discharge port 120. When the ejection mechanism 300 ejects the product 700 corresponding to the discharge port 120, the adjacent product 700 will also be subjected to a force toward the stacking channel 220. In order to prevent the adjacent product 700 from being pushed out of the feeding channel 110, in this embodiment, the product 700 is stacked above the product 700 corresponding to the discharge port 120. Figure 2 A limiting spring piece 150 is provided above the material delivery mechanism 100 corresponding to the discharge port 120 , and the limiting spring piece 150 is used to abut against the product 700 in the material delivery channel 110 .

[0054] It can be understood that the limiting spring piece 150 is used to abut against the product 700 near the discharge port 120 to limit the product 700 in the feed channel 110, preventing the product 700 that has not reached the position corresponding to the discharge port 120 from being pushed out, so as to ensure the orderly output of the product 700.

[0055] Regarding the stacking method of the stacking channel 220, refer to Figure 2 The inner wall of the stacking channel 220 is provided with a plurality of stoppers 210 along the length direction of the stacking channel 220, and a limiting position is formed between adjacent stoppers 210, and the limiting position is used to clamp the product 700, and the stoppers 210 can be deformed to allow the product 700 to enter another limiting position.

[0056] It is understood that after the product 700 is pushed into the stacking channel 220, it will be stuck in one of the restriction positions to prevent the product 700 from falling over and keep the product 700 in an upright position. After the second product 700 is pushed in, the first product 700 is subjected to force and can push away the blocking member 210, causing the blocking member 210 to deform, allowing the first product 700 to enter the next restriction position, and the second product 700 will enter the restriction position originally located by the first product 700. This cycle continues, so that the products 700 are stacked in the stacking channel 220 in an upright position.

[0057] Specifically, in this embodiment, the material blocking member 210 is a brush. In other embodiments, the material blocking member 210 can also be a plastic pick or a spring.

[0058] Regarding the way in which the product 700 enters the feeding mechanism 100, in this embodiment, refer to Figure 1 and Figure 3The stacking device of the present application also includes a conveying mechanism 600, which includes a conveying track 610 and an adjustment part 630. The conveying track 610 is arranged in a horizontal direction, and the conveying track 610 forms a conveying channel 620. The conveying channel 620 is connected to the feed port of the feed channel 110. The adjustment part 630 drives the connected conveying track 610 to adjust the inclination angle of the conveying track 610 relative to the horizontal plane.

[0059] It will be understood that the conveying channel 620 is used to receive products 700 in a flat position. The conveying mechanism 600 is capable of transporting the products 700 within the conveying track 610. The conveying channel 620 interfaces with the feed port of the feed channel 110, allowing the flat products 700 to enter the feed channel 110. It will also be understood that the adjustment portion 630 drives the conveying track 610 to tilt the conveying track 610 relative to the horizontal plane, allowing the products 700 within the conveying channel 620 to slide into the feed channel 110 under the action of gravity.

[0060] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
