Abstract
Description
Technical Field
[0001] This invention relates to the field of plastic bag packaging technology, and more specifically, to a plastic bag palletizing device and its method of use. Background Technology
[0002] The continuous roll bag making machine is a core piece of equipment in the plastic packaging industry used for the mass production of continuous roll garbage bags. Its working principle involves heat-sealing, slitting, and rolling plastic film to create continuous garbage bag rolls. A cutting mechanism then divides the continuous roll into individual garbage bag rolls of preset lengths. Currently, after cutting, the garbage bag rolls produced by the continuous roll bag making machine typically fall directly from the machine's output end into a collection bin and are collected by natural stacking.
[0003] However, garbage bag rolls are mostly cylindrical in shape, and when they fall directly into the collection bins, they tend to roll and stack messily, making automatic stacking impossible. This requires manual sorting and stacking of the garbage bag rolls in the collection bins, which not only increases the intensity of manual labor but also leads to low stacking efficiency. Furthermore, manual stacking results in poor consistency, with problems such as loose stacking and skewing, affecting the subsequent transfer, storage, and packaging of the collection bins. Summary of the Invention
[0004] The purpose of this invention is to overcome the defects in the prior art and provide a plastic bag palletizing device and its usage method that achieves automatic and accurate palletizing through a transfer mechanism.
[0005] To achieve the above objectives, the technical solution of the present invention is to provide a plastic bag palletizing device, comprising: a conveying mechanism for conveying garbage bag rolls; A material-carrying mechanism, connected to the conveying mechanism, is used to receive the garbage bag rolls conveyed by the conveying mechanism; The transfer mechanism includes a robotic arm located on the side of the conveying mechanism, and a clamping assembly is mounted on the end effector of the robotic arm; A collection mechanism includes a conveying component and a collection box. The conveying component is located on the side of the conveying mechanism, and the collection box is located on the conveying component. The robotic arm automatically stacks the garbage bag rolls by controlling the position of the clamping component to place the garbage bag rolls into the collection box.
[0006] Preferably, the conveying mechanism includes a conveyor body and a first pusher, the first pusher being fixedly installed on the conveyor body, the first pusher corresponding to the loading mechanism, and the first pusher and the loading mechanism being respectively located on both sides of the conveyor body. With this design, the first pusher can push the garbage bag roll into the loading mechanism.
[0007] Preferably, the conveyor body has two sets of relatively parallel limiting plates along the conveying direction, and the distance between the two sets of limiting plates is slightly larger than the radial dimension of the garbage bag roll. This design ensures that the axial direction of the garbage bag roll is basically consistent with the conveying direction of the conveyor body, so that the first pusher can easily and accurately push the garbage bag roll into the loading mechanism.
[0008] Preferably, the material loading mechanism includes a guide plate and a baffle assembly. The guide plate is inclined downwards in a direction away from the conveyor body, with its high end connected to the conveyor body and its low end connected to the baffle assembly. This design allows the material loading mechanism to guide the garbage bag roll to the corner where the guide plate and baffle assembly connect, facilitating clamping and transfer by the clamping assembly.
[0009] Preferably, the baffle assembly includes a first baffle plate and a second baffle plate connected to the end of the guide plate, with a clamping opening between the first baffle plate and the second baffle plate. The width of the clamping opening is smaller than the axial dimension of the garbage bag roll. This design facilitates the clamping assembly in clamping the garbage bag roll and avoids clamping interference.
[0010] Preferably, the material loading mechanism further includes a positioning side plate and a second pushing member. The positioning side plate is fixedly connected to the guide plate, and both the guide plate and the first baffle plate are perpendicular to the positioning side plate. The second pushing member is installed on the guide plate, and its second pushing plate is parallel to the positioning side plate. This design allows the second pushing member to push the garbage bag roll to the clamping position, ensuring that the clamping assembly can accurately clamp the middle of the garbage bag roll.
[0011] Preferably, the clamping assembly includes a clamping seat, a fixed claw, a movable claw unit, and an adjusting cylinder. The clamping seat is fixedly mounted on the end effector of the robotic arm, the fixed claw is fixedly mounted on the clamping seat, the movable claw unit is mounted on the sliding unit of the clamping seat, one end of the adjusting cylinder is connected to the clamping seat, and the other end of the adjusting cylinder is connected to the sliding end of the sliding unit. The fixed claw and the sliding claw of the moving claw unit have an adjustable spacing, and the sliding claw has a slot on the side near the fixed claw. This design helps to improve the stability of the clamping assembly in holding the garbage bag roll.
[0012] Preferably, the sliding claw includes a straight plate, a V-shaped plate, and a rotating plate. The straight plate is fixedly connected to the sliding unit, one end of the V-shaped plate is fixedly connected to the straight plate, and the other end of the V-shaped plate is rotatably connected to the rotating plate via a rotating shaft. The V-shaped plate and the rotating plate cooperate to form the slot. The moving claw unit also includes a torsion spring, a guide rod cylinder, and a traction rope. The torsion spring is sleeved on the outer ring of the rotating shaft. One end of the torsion spring is fixedly connected to the V-shaped plate, and the other end is fixedly connected to the rotating plate. The guide rod cylinder is fixedly installed on the straight plate near the fixed claw. A rotating shaft is rotatably mounted on the end of the rotating plate near the V-shaped plate. One end of the traction rope is connected to the output end at the top of the guide rod cylinder, and the other end is connected to the rotating shaft. The V-shaped plate has a channel for the traction rope to pass through, and the straight plate has a through hole for the traction rope to pass through. This design helps to ensure the tightness of the garbage bag rolls stacked inside the collection bin.
[0013] Preferably, the conveying assembly includes a base, a support, a roller conveyor, a first lifting cylinder and a second lifting cylinder, with the base located on the side of the robotic arm away from the conveyor body; Along the conveying direction of the conveyor body, one end of the support is hinged to the base, the other end of the support is hinged to the output end of the first lifting cylinder, and the fixed end of the first lifting cylinder is hinged to the base. Along a conveying direction perpendicular to the conveyor body, one end of the roller conveyor is hinged to the support base, and the other end of the roller conveyor is hinged to the output end of the second lifting cylinder. The fixed end of the second lifting cylinder is hinged to the support base, and the collection box is mounted on the roller conveyor. This design helps ensure the tightness of the garbage bag rolls.
[0014] A method of using a plastic bag palletizing device includes the following steps: S1. The conveying mechanism conveys the garbage bag roll between the first pusher and the loading mechanism; S2. The first pusher pushes the garbage bag roll into the loading mechanism; S3. The transfer mechanism transfers the garbage bag roll in the loading mechanism to the collection box and automatically stacks it; S4. Repeat S1-S3.
[0015] The beneficial effects of this invention are as follows: By using the plastic bag palletizing equipment and its usage method described in this invention, a complete automatic palletizing process is constructed through the coordinated operation of four major mechanisms: conveying mechanism, material loading mechanism, transfer mechanism, and collection mechanism. This completely replaces manual palletizing, significantly reduces the intensity of manual labor, improves palletizing efficiency, and ensures the consistency and regularity of palletizing. It also facilitates the subsequent transfer and storage of collection boxes, solving the core pain point of the inconvenience of traditional manual palletizing. Attached Figure Description

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.
[0019] To better understand this invention, the following is combined with... Figures 1-18 A plastic bag palletizing device and its usage method according to the present invention will be described in detail.
[0020] Example 1: like Figure 1 As shown, a plastic bag palletizing device includes: a conveying mechanism 1 for conveying garbage bag rolls 5; The material loading mechanism 2 is connected to the conveying mechanism 1 and is used to receive the garbage bag rolls 5 conveyed by the conveying mechanism 1. The transfer mechanism 3 includes a robotic arm 31 located on the side of the conveying mechanism 1, and a clamping assembly is installed on the end effector of the robotic arm 31. The collection mechanism 4 includes a conveying component 41 and a collection box 42. The conveying component 41 is located on the side of the conveying mechanism 1, and the collection box 42 is located on the conveying component 41. The robotic arm 31 automatically stacks the garbage bag rolls 5 into the collection box 42 by controlling the position of the clamping component.
[0021] It should be noted that the conveying mechanism 1, the loading mechanism 2, the transfer mechanism 3, and the collection mechanism 4 are arranged in sequence. The conveying mechanism 1 is used to receive the garbage bag rolls 5 produced by the continuous roll bag making machine (not shown in the figure) and convey them to the loading mechanism 2. After the garbage bag rolls 5 fall into the loading mechanism 2, they reach the preset position of the loading mechanism 2. Subsequently, the robotic arm 31 controls the movement of the clamping component, which clamps the garbage bag rolls 5 at the preset position and transfers them into the collection box 42. When the garbage bag rolls 5 are placed into the collection box 42, the robotic arm 31 releases the garbage bag rolls 5 by controlling the clamping component. The position enables automatic stacking of garbage bag rolls 5 in the collection box 42. The conveying component 41 and the robotic arm 31 are located on the same side of the conveying mechanism 1, so that the robotic arm 31 can transfer the garbage bag rolls 5 in the loading mechanism 2 to the collection box 42 through the clamping component. When the collection box 42 is full of stacked garbage bag rolls 5, the conveying component 41 conveys the collection box 42 to the next conveying line (not shown in the figure). Another conveying device (not shown in the figure) conveys the empty collection box 42 to the conveying component 41, so as to continue collecting the garbage bag rolls 5 transferred by the transfer mechanism 3.
[0022] By using the plastic bag palletizing equipment of the present invention, a complete automatic palletizing process is constructed through the coordinated operation of four major mechanisms: conveying mechanism 1, material loading mechanism 2, transfer mechanism 3, and collection mechanism 4. This completely replaces manual palletizing, significantly reduces the intensity of manual labor, improves palletizing efficiency, and ensures the consistency and regularity of palletizing. It also facilitates the subsequent transfer and storage of the collection box 42, solving the core pain point of the inconvenience of traditional manual palletizing.
[0023] Example 2: As an optimization of Example 1, such as Figure 1 and Figure 2 As shown, the conveying mechanism 1 includes a conveyor body 11 and a first pusher 12. The first pusher 12 is fixedly installed on the conveyor body 11. The first pusher 12 corresponds to the position of the loading mechanism 2, and the first pusher 12 and the loading mechanism 2 are respectively located on both sides of the conveyor body 11.
[0024] It should be noted that the conveyor body 11 is a belt conveyor, and the first pusher 12 can be a telescopic drive structure such as a cylinder or an electric push rod. The output end of the first pusher 12 is fixedly installed with a first push plate 121. When the conveyor body 11 conveys the garbage bag roll 5 to the push position corresponding to the first pusher 12, the output end of the first pusher 12 extends, thereby pushing the garbage bag roll 5 into the loading mechanism 2 through the first push plate 121. The angle between the axial direction of the garbage bag roll 5 and the conveying direction of the conveyor body 11 does not exceed a preset angle. Preferably, the axial direction of the garbage bag roll 5 is the same as the conveying direction of the conveyor body 11. On the one hand, under the action of friction, the garbage bag roll 5 will not move along the conveying direction, ensuring that the first pusher 12 can accurately push the garbage bag roll 5 into the loading mechanism 2. On the other hand, when the first pusher 12 pushes the garbage bag roll 5, the garbage bag roll 5 will automatically roll into the loading mechanism 2, ensuring that the first pusher 12 can easily push the garbage bag roll 5 into the loading mechanism 2.
[0025] In this embodiment, a photoelectric switch 13 is provided at the pushing position of the conveyor body 11. The photoelectric switch 13 is electrically connected to the controller of the first pushing component 12. The photoelectric switch 13 and the first pushing component 12 are arranged sequentially along the conveying direction of the conveyor body 11. The transmitter 131 and receiver 132 of the photoelectric switch 13 are respectively fixedly installed on both sides of the conveyor body 11. The transmitter 131 emits infrared light, visible light and other light beams, and the receiver 132 receives them accordingly. When the garbage bag roll 5 passes through the photoelectric switch 13, the light beam emitted by the transmitter 131 is blocked by the garbage bag roll 5, and the receiver 132 cannot receive the signal of the transmitter 131, thereby triggering a change in the electrical signal. After receiving the change in the electrical signal, the controller of the first pushing component 12 controls the first pushing component 12 to make a pushing action after a period of time. It should be emphasized that from the time the controller of the first pusher 12 receives the change of the electrical signal to the time the first pusher 12 makes the pushing action, the garbage bag roll 5 is conveyed from the position corresponding to the photoelectric switch 13 by the conveyor body 11 to the space between the first pusher 12 and the loading mechanism 2. The first pusher 12 makes a pushing action, thereby pushing the garbage bag roll 5 into the loading mechanism 2 through the first push plate 121. The linkage control between the photoelectric switch 13 and the first pusher 12 realizes the automation and precision of the pushing action, avoids missed pushing and incorrect pushing, and ensures that each garbage bag roll 5 can accurately enter the loading mechanism 2, thus ensuring the continuity and stability of the entire palletizing process. In this embodiment, a limiting frame 14 is also installed on the conveyor body 11. The first pusher 12 and the limiting frame 14 are arranged sequentially along the conveying direction of the conveyor body 11. A blocking plate 141 is installed on the limiting frame 14. The blocking plate 141 is used to stop the garbage bag roll 5 conveyed by the conveyor body 11 so that the first pusher 12 can stably push the garbage bag roll 5 into the loading mechanism 2. That is, during the process of the first pusher 12 pushing the garbage bag roll 5, the garbage bag roll 5 only rolls and does not move along the conveying direction of the conveyor body 11. If the blocking plate 141 is not set, during the process of the garbage bag roll 5 being pushed by the first pusher 12, the conveyor body 11 continues to convey the garbage bag roll 5. The position of the first pusher 12 pushing the garbage bag roll 5 will gradually move towards the edge of the garbage bag roll 5, which may cause the garbage bag roll 5 to roll crookedly, thus causing the garbage bag roll 5 to fail to fall into the preset area of the loading mechanism 2.
[0026] Example 3: As an optimization of Example 2, such as Figures 1-4 As shown, the conveyor body 11 is provided with two sets of relatively parallel limiting plates along the conveying direction, and the distance between the two sets of limiting plates is slightly larger than the radial dimension of the garbage bag roll 5.
[0027] It should be noted that two sets of limiting plates are installed on both sides of the conveyor body 11. The garbage bag roll 5 on the conveyor body 11 is located between the two sets of limiting plates. The two sets of parallel limiting plates restrict the position of the garbage bag roll 5 on the conveyor body 11 through two sets of vertical limiting surfaces. This ensures that the axial direction of the garbage bag roll 5 is basically consistent with the conveying direction of the conveyor body 11. By setting the distance between the two sets of limiting plates to be slightly larger than the radial dimension of the garbage bag roll 5, the two sets of limiting plates can be prevented from affecting the conveying of the garbage bag roll 5. It can also effectively limit the rolling of the garbage bag roll 5 during the conveying process, ensuring that the garbage bag roll 5 is conveyed smoothly along the conveying direction, and ensuring that the first pusher 12 can accurately push the garbage bag roll 5 onto the loading mechanism 2.
[0028] In this embodiment, the two sets of limiting plates are a first limiting plate 15 and a second limiting plate 16. The first limiting plate 15 is located between the second limiting plate 16 and the robotic arm 31. Both the first limiting plate 15 and the second limiting plate 16 are fixedly installed on the conveyor body 11 by bolts and nuts. The first limiting plate 15 has a circular hole 151 for bolts to pass through, and multiple circular holes 151 are arranged along the conveying direction. The installation position of the first limiting plate 15 is not adjustable. The second limiting plate 16 has a strip hole 161 for bolts to pass through, and multiple strip holes 161 are arranged along the conveying direction. The length direction of the strip hole 161 is perpendicular to the conveying direction. The position of the bolt in the strip hole 161 is adjustable. The installation position of the second limiting plate 16 is adjustable, thereby adjusting the distance between the first limiting plate 15 and the second limiting plate 16 to accommodate garbage bag rolls 5 with different radial dimensions, which is beneficial to improving the applicability of the plastic bag palletizing equipment. It should be emphasized that a material drop plate 17 is also installed on the conveyor body 11. The material drop plate 17 is inclined downward along the direction close to the second limit plate 16. After the garbage bag roll 5 falls from the fully automatic continuous roll garbage bag making machine (not shown in the figure), it falls onto the material drop plate 17 and rolls along the material drop plate onto the belt of the conveyor body 11, where it is blocked by the second limit plate 16. Subsequently, the garbage bag roll 5 is conveyed between the first limit plate 15 and the second limit plate 16.
[0029] Example 4: As an optimization of Example 3, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the material loading mechanism 2 includes a guide plate 21 and a baffle assembly. The guide plate 21 is inclined downward in a direction away from the conveyor body 11. The high end of the guide plate 21 is connected to the conveyor body 11, and the low end of the guide plate 21 is connected to the baffle assembly. The baffle assembly includes a first baffle plate 22 and a second baffle plate 23 connected to the end of the guide plate 21. A clamping opening 201 is provided between the first baffle plate 22 and the second baffle plate 23. The width of the clamping opening 201 is smaller than the axial dimension of the garbage bag roll 5. The material loading mechanism 2 also includes a positioning side plate 25 and a second pusher 26. The positioning side plate 25 is fixedly connected to the guide plate 21. The guide plate 21 and the first baffle plate 22 are both perpendicular to the positioning side plate 25. The second pusher 26 is installed on the guide plate 21, and the second pusher plate 261 of the second pusher 26 is parallel to the positioning side plate 25.
[0030] It should be noted that the guide plate 21 is used to guide the garbage bag roll 5 pushed down from the conveyor body 11 to roll to the corner where the guide plate 21 and the baffle assembly are connected. The baffle assembly is provided with a blocking surface perpendicular to the guide plate 21, so as to prevent the garbage bag roll 5 from falling off the loading mechanism 2, so as to facilitate the clamping assembly to clamp and transfer it. By setting the clamping port 201, the clamping component can be conveniently clamped in the garbage bag roll 5, and interference between the clamping component and the first baffle plate 22 and / or the second baffle plate 23 can be avoided during the clamping process. When the garbage bag roll 5 rolls down to the corner where the guide plate 21 and the baffle assembly connect, the first baffle plate 22, the second baffle plate 23 and the guide plate 21 all contact the peripheral side of the garbage bag roll 5. The second pusher 26 pushes the garbage bag roll 5 towards the positioning side plate 25 through the second pusher plate 261 until the end face of the garbage bag roll 5 is in contact with the positioning side plate 25, thereby adjusting the garbage bag roll 5 to the clamping position, ensuring that the clamping assembly can accurately clamp the middle of the garbage bag roll 5, and further ensuring the stability of the clamping.
[0031] In this embodiment, the first baffle plate 22 is fixedly connected to the guide plate 21, and a strip 24 is fixedly connected to the bottom surface of the guide plate 21. A groove 202 is formed between the strip 24 and the guide plate 21. The second baffle plate 23 is slidably connected to the groove 202. By adjusting the position of the second baffle plate 23 in the groove 202, the size of the clamping opening 201 can be adjusted to accommodate garbage bag rolls 5 with different axial dimensions, ensuring that the clamping assembly can clamp the middle section of the garbage bag roll 5 and ensuring stable clamping of garbage bag rolls 5 with different axial dimensions.
[0032] Example 5: As an optimization of Example 4, such as Figure 1 , Figure 8 and Figure 9 As shown, the clamping assembly includes a clamping seat 32, a fixed claw 33, a movable claw unit, and an adjusting cylinder 34. The clamping seat 32 is fixedly mounted on the end effector of the robotic arm 31, the fixed claw 33 is fixedly mounted on the clamping seat 32, the movable claw unit is mounted on the sliding unit of the clamping seat 32, one end of the adjusting cylinder 34 is connected to the clamping seat 32, and the other end of the adjusting cylinder 34 is connected to the sliding end of the sliding unit. The fixed claw 33 and the sliding claw 35 of the moving claw unit have an adjustable gap, and the sliding claw 35 is provided with a slot 3501 on the side of the fixed claw 33.
[0033] It should be noted that the adjusting cylinder 34 can adjust the distance between the moving claw unit and the fixed claw 33, thereby adjusting the distance between the sliding claw 35 and the fixed claw 33 to clamp the garbage bag roll 5. The trapezoidal cross-section of the slot 3501 limits the garbage bag roll 5 during the clamping process, which can prevent the garbage bag roll 5 from falling out of the gap between the fixed claw 33 and the sliding claw 35, and improve the stability of the clamping component in clamping the garbage bag roll 5.
[0034] In this embodiment, the sliding unit includes a guide rail 36, a slider 37, and a mounting base 38. The guide rail 36 is fixedly mounted on the clamping base 32, and the length direction of the guide rail 36 is along the direction of the sliding claw 35 pointing towards the fixed claw 33 (the fixed claw 33 is essentially a flat plate, and the length direction of the guide rail 36 is perpendicular to the plane where the fixed claw 33 is located). The slider 37 is slidably mounted on the guide rail 36, and the mounting base 38 is fixedly mounted on the slider 37. The sliding claw 35 is fixedly mounted on one end of the mounting base 38 near the fixed claw 33. One end of the adjusting cylinder 34 is fixedly connected to the clamping base 32, and the other end of the adjusting cylinder 34 is fixedly connected to the mounting base 38. The adjusting cylinder 34 can drive the slider 37, the mounting base 38, and the moving claw unit to move along the length direction of the guide rail 36 through its own extension and retraction adjustment, thereby adjusting the distance between the fixed claw 33 and the sliding claw 35. Thus, the sliding claw 35 and the fixed claw 33 can cooperate to clamp or release the garbage bag roll 5. During the clamping process, the fixed claw 33 is in contact with the lower end of the guide plate 21, and the sliding claw 35 is located on the side of the first baffle plate 22 near the conveyor body 11. The sliding claw 35 moves closer to the fixed claw 33, and the slot 3501 is aligned with the garbage bag roll 5, thereby clamping the garbage bag roll 5. In addition, the width of both the fixed claw 33 and the sliding claw 35 is smaller than the width of the clamping opening 201 to avoid the sliding claw 35 colliding with the first baffle plate 22 or the second baffle plate 23 during the clamping process.
[0035] Example 6: As an optimization of Example 5, such as Figures 9-16 As shown, the sliding claw 35 includes a straight plate 351, a V-shaped plate 352, and a rotating plate 353. The straight plate 351 is fixedly connected to the sliding unit. One end of the V-shaped plate 352 is fixedly connected to the straight plate 351, and the other end of the V-shaped plate 352 is rotatably connected to the rotating plate 353 through a rotating shaft 3531. The V-shaped plate 352 and the rotating plate 353 cooperate to form a slot 3501. The moving claw unit also includes a torsion spring 391, a guide rod cylinder 392, and a traction rope 393. The torsion spring 391 is sleeved on the outer ring of the rotating shaft 3531. One end of the torsion spring 391 is fixedly connected to the V-shaped plate 352, and the other end of the torsion spring 391 is fixedly connected to the rotating plate 353. The guide rod cylinder 392 is fixedly installed on the side of the straight plate 351 near the fixed claw 33. The rotating plate 353 is rotatably mounted with a rotating shaft 3532 at one end near the V-shaped plate 352. One end of the traction rope 393 is connected to the output end at the top of the guide rod cylinder 392, and the other end of the traction rope 393 is connected to the rotating shaft 3532. The V-shaped plate 352 is provided with a channel 3521 for the traction rope 393 to pass through, and the straight plate 351 is provided with a through hole 3511 for the traction rope 393 to pass through.
[0036] It should be noted that the straight plate 351 is fixedly connected to the end of the mounting base 38 near the fixing claw 33. The torsion spring 391 is located between the V-shaped plate 352 and the rotating plate 353. Two torsion springs 391 are provided in mirror image about the symmetrical plane of the rotating plate 353 to ensure the stability of the rotation of the rotating plate 353. The rotating shaft 3532 is located on the side of the rotating shaft 3531 near the V-shaped plate 352. In other words, compared with the rotating shaft 3532, the rotating shaft 3531 is closer to the central area of the rotating plate 353. The length direction of the channel 3521 is parallel to the plate surface of the V-shaped plate 352 near the rotating plate 353, and the channel 3521 passes through the plate segment of the V-shaped plate 352 near the rotating plate 353. In the initial state, the traction rope 393 does not provide traction force. Under the action of the torsion spring 391, the V-shaped plate 352 and the rotating plate 353 cooperate to form a slot 3501. After the clamping assembly clamps the garbage bag roll 5 on the loading mechanism 2 and transfers it to the preset position in the collection box 42, the output end of the guide rod cylinder 392 retracts, pulling the traction rope 393. The traction rope 393 pulls the rotating shaft 3532, thereby causing the rotating plate 353 to rotate around the axis of the rotating shaft 3531 until the rotating plate 353 is parallel to the straight plate 351. The openings at the bottom of the fixed claw 33 and the sliding claw 35 expand. The sliding claw 35 only needs to move a small distance away from the fixed claw 33 to release the clamping force of the fixed claw 33 and the sliding claw 35 on the garbage bag roll 5. The garbage bag roll 5 can be stacked in the preset position after the clamping assembly is withdrawn. Therefore, the stacking of the garbage bag roll 5 in the collection box 42 is more compact and reliable, and the garbage bag roll 5 in the collection box 42 will not be misaligned during transportation. Without the above structure, i.e., the rotating plate 353 cannot be rotated and adjusted, when releasing the garbage bag roll 5, the rotating plate 353 will prevent the garbage bag roll 5 from falling into the collection box 42. It is necessary to adjust the sliding claw 35 to make the distance between the sliding claw 35 and the fixed claw 33 larger in order to ensure that the garbage bag roll 5 can be smoothly released from the clamping component. When stacking the last row of garbage bag rolls 5 (among the garbage bag rolls 5 in the same layer, and with the collection box 42 tilted, the garbage bag rolls 5 in this row are at the highest position), a larger gap needs to be left for the opening of the clamping component. This will result in the garbage bag rolls 5 in the collection box 42 not being stacked tightly. When the collection box 42 is flattened, the garbage bag rolls 5 in the upper layer will fall into the gap in the lower layer of the collection box 42, resulting in a poor stacking effect of the garbage bag rolls 5. When the clamping assembly is removed, the guide rod cylinder 392 resets, and the rotating plate 353 and the traction rope 393 automatically reset under the action of the torsion spring 391. In addition, during the retraction of the output end of the guide rod cylinder 392, the rod 3921 of the guide rod cylinder 392 moves toward the rotating plate 353 and pushes the garbage bag roll 5 outward, which helps the garbage bag roll 5 to detach from the clamping assembly and fall into the preset position in the collection box 42.
[0037] In this embodiment, the rotating shaft 3531 is fixedly connected to the rotating plate 353 and integrally formed. The rotating shaft 3531 is rotatably connected to the V-shaped plate 352. The output end of the guide rod cylinder 392 is fixedly provided with a connecting ring 3922. One end of the traction rope 393 is tied to the rotating shaft 3532, and the other end of the traction rope 393 is tied to the connecting ring 3922. In addition, the number of traction ropes 393, channels 3521, through holes 3511 and connecting rings 3922 are the same, and multiple sets of each are provided to ensure that the rotation adjustment of the rotating plate 353 is more stable and reliable.
[0038] Example 7: As an optimization of Example 6, such as Figure 1 , Figure 17 and Figure 18 As shown, the conveying assembly 41 includes a base 411, a support 412, a roller conveyor 413, a first lifting cylinder 414 and a second lifting cylinder 415. The base 411 is located on the side of the robotic arm 31 away from the conveyor body 11. Along the conveying direction of the conveyor body 11, one end of the support base 412 is hinged to the base 411, the other end of the support base 412 is hinged to the output end of the first lifting cylinder 414, and the fixed end of the first lifting cylinder 414 is hinged to the base 411. Along the conveying direction perpendicular to the conveyor body 11, one end of the roller conveyor 413 is hinged to the support base 412, the other end of the roller conveyor 413 is hinged to the output end of the second lifting cylinder 415, the fixed end of the second lifting cylinder 415 is hinged to the support base 412, and the collection box 42 is provided on the roller conveyor 413.
[0039] It should be noted that, along the conveying direction of the conveyor body 11, the end of the support base 412 near the material loading mechanism 2 is hinged to the base 411, and the end of the support base 412 away from the material loading mechanism 2 is hinged to the output end of the first lifting cylinder 414; along the conveying direction perpendicular to the conveyor body 11, the end of the roller conveyor 413 near the robotic arm 31 is hinged to the support base 412, and the end of the roller conveyor 413 away from the robotic arm 31 is hinged to the output end of the second lifting cylinder 415; The output end of the first lifting cylinder 414 extends, which can lift the support base 412, the roller conveyor 413 and the collection box 42 away from the loading mechanism 2. The output end of the second lifting cylinder 415 extends, which can lift the roller conveyor 413 and the collection box 42 away from the robotic arm 31. This causes the collection box 42 to tilt towards a corner closer to itself, and this corner is the corner of the collection box 42 closer to the robotic arm 31. When the transfer mechanism 3 stacks the garbage bag rolls 5 in the collection box 42, it first stacks the lower column or row, and then stacks the higher column or row. This avoids the garbage bag rolls 5 from rolling away from each other that may occur when the collection box 42 is laid flat and stacked. In addition, by adjusting the tilt angle of the collection box 42, if the garbage bag rolls 5 placed in the collection box 42 do not come together, they will automatically roll or slide under the action of gravity, thereby making the garbage bag rolls 5 automatically come together and ensuring the tightness of the stacking. When the collection box 42 is filled with garbage bag rolls 5, the output ends of the first lifting cylinder 414 and the second lifting cylinder 415 shorten, the roller conveyor 413 gradually flattens, and the roller conveyor 413 transports the full collection box 42 to the next conveyor line. Meanwhile, another conveyor on the side transports the empty collection box 42 to the roller conveyor 413. The output ends of the first lifting cylinder and the second lifting cylinder 415 extend again, thereby causing the collection box 42 to tilt toward the corner closer to the robotic arm 31.
[0040] In this embodiment, the conveying direction of the conveying device for conveying empty collection boxes 42 is perpendicular to the conveying direction of the conveyor body 11. Along the conveying direction perpendicular to the conveyor body 11, a baffle 416 is also fixedly installed at one end of the roller conveyor 413 near the robotic arm 31. After the empty collection box 42 is conveyed onto the roller conveyor 413, it is blocked by the baffle 416, thereby ensuring that the collection box 42 can fall to the preset position on the roller conveyor 413, which is beneficial to improving the accuracy and reliability of palletizing. The base 411 and the support 412 are hinged together by a hinge, and the support 412 and the roller conveyor 413 are hinged together by a hinge. The base 411 and the support 412 are both hinged together with the first lifting cylinder 414 through a hinge seat, and the support 412 and the roller conveyor 413 are both hinged together with the second lifting cylinder 415 through a hinge seat.

The conveying mechanism 1 conveys the garbage bag roll 5 between the first pusher 12 and the loading mechanism 2; S2, the first pusher 12 pushes the garbage bag roll 5 into the loading mechanism 2; S3, the transfer mechanism 3 transfers the garbage bag roll 5 in the loading mechanism 2 to the collection box 42 and automatically stacks it; S4. Repeat S1-S3.
[0042] It should be noted that in S2, after the garbage bag roll 5 falls into the loading mechanism 2, the second pusher 26 pushes the garbage bag roll 5 so that the garbage bag roll 5 fits against the positioning side plate 25. S3 includes the following steps: S31, the robotic arm 31 drives the clamping assembly to align with the clamping port 201, and the clamping assembly clamps the garbage bag roll 5 on the loading mechanism 2; S32, the robotic arm 31 drives the gripping assembly to transfer the garbage bag roll 5 to the preset position in the collection box 42; S33, the guide rod cylinder 392 pulls the rotating shaft 3532 through the traction rope 393, so that the rotating plate 353 rotates to be parallel to the straight plate 351; S34, the sliding claw 35 moves away from the fixed claw 33 to release the garbage bag roll 5; S35, the robotic arm 31 drives the gripper 32 to reset; S36, the guide rod cylinder 392 resets, the torsion spring 391 drives the rotating plate 353 to reset, and the transfer mechanism 3 completes the reset.
