Description

Technical Field

[0001] This invention relates to the field of palletizing device technology, specifically to an automatic palletizing device for a nonwoven intelligent production line. Background Technology

[0002] The production process of non-woven fabrics often requires handling and packaging in rolls. Most non-woven fabric stacking on the market requires manual operation, which is labor-intensive for workers. Moreover, the products may be damaged or unevenly placed if the operation is not careful.

[0003] To achieve fully automated palletizing of nonwoven fabric rolls, robotic arms are typically used on production lines. The opening and closing of the gripper structure at the robotic arm's gripping end allows for the picking and placing of nonwoven fabric rolls, thus achieving automated palletizing. However, in actual operation, the grippers operate without protective covers, directly exposed to the air. Dust from the production line floor and debris (such as plastic particles) from the outside of the nonwoven fabric rolls adhere to the grippers as they move. The robotic arm's grippers inevitably become contaminated with dust, impurities, and other pollutants. If not cleaned promptly, these contaminants can reduce the gripping accuracy and stability of the grippers. Furthermore, since the grippers are in direct contact with the nonwoven fabric rolls, the cleanliness of their surfaces directly affects the quality of the nonwoven fabric. Summary of the Invention

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1 and Figure 2 The figure shows an automatic palletizing device for a nonwoven intelligent production line, which includes a conveyor 1 for conveying nonwoven rolls. One end of the conveyor 1 is equipped with a robotic arm 2 for automatically palletizing the nonwoven rolls. In use, the conveyor 1 transports the rolled nonwoven rolls to the discharge end, and the robotic arm 2 grabs the nonwoven rolls. The grabbed nonwoven rolls are then stacked on one side, thereby realizing fully automatic palletizing of nonwoven rolls.

[0037] It also includes: a gripping unit 3 installed at the front end of the robotic arm 2. The gripping unit 3 is used to pick up and put down non-woven fabric. A combined cleaning unit 4 is installed on the outside of the gripping unit 3. The combined cleaning unit 4 is used to clean the gripping end of the gripping unit 3. The designed combined cleaning unit 4 can perform cleaning treatment during the process of the gripping unit 3 picking up and putting down non-woven fabric, thereby quickly removing dust, impurities and other contaminants from the gripping unit 3 in a timely manner, and avoiding the presence of contaminants that reduce the gripping accuracy and stability of the gripping unit 3.

[0038] The lubrication unit 5 is installed on the upper side of the clamping unit 3. The lubrication unit 5 is used to automatically maintain the upper end of the clamping unit 3. The bottom end of the lubrication unit 5 is equipped with an oil replenishment unit 6. During the operation of the clamping unit 3, the moving end of the clamping unit 3 can be automatically maintained and repaired through the cooperation of the lubrication unit 5 and the oil replenishment unit 6, thereby improving the service life of the clamping unit 3.

[0039] For further details, please refer to [link / reference]. Figure 2 and Figure 3 The gripping unit 3 includes a double-acting cylinder 301, a first connecting plate 302, a guide rail 303, a slide 304, and grippers 305. The double-acting cylinder 301 is installed at the front end of the robotic arm 2. The first connecting plate 302 is fixed at both ends of the double-acting cylinder 301. The first connecting plate 302 is fixed to one end of the slide 304. The first connecting plate 302 is fixedly connected to the grippers 305 through the slide 304. The guide rail 303 is fixed to the bottom of the double-acting cylinder 301. The slide 304 is slidably connected to the guide rail 303. Anti-slip plates 306 are fixed on the adjacent sides of the two grippers 305. A transmission component 307 is fixed to one end of the first connecting plate 302. One end of the combined cleaning unit 4 is connected to the transmission component 307. The lubrication unit 5 is located above the guide rail 303 and is used to automatically maintain the groove on the top of the slide 304.

[0040] Specifically, see Figure 1 and Figure 3 When the robotic arm 2 moves to the discharge end of the conveyor 1, the two grippers 305 move closer to the non-woven fabric roll on the conveyor 1 by moving the robotic arm 2 downward. Then, the two slides 304 and the two grippers 305 move closer to each other through the double-acting cylinder 301, thereby clamping the non-woven fabric roll. After clamping, the robotic arm 2 moves upward and the base rotates 90 degrees to transport the clamped roll to one side. Then the robotic arm 2 moves downward to the stacking position and releases the two grippers 305, thereby automatically picking up and placing the non-woven fabric roll. By continuing to perform the above steps, batches of non-woven fabric rolls can be stacked in a regular manner.

[0041] For further details, please refer to [link / reference]. Figure 2 and Figure 4The combined cleaning unit 4 includes a sealing cylinder 401, a piston block 402, a piston rod 403, an air inlet pipe 404, an air outlet pipe 405, and an air blowing component 406. The sealing cylinder 401 is fixed to the outside of the double-acting cylinder 301. The piston block 402 is slidably connected inside the sealing cylinder 401. One end of the piston rod 403 is fixed to the piston block 402. One end of the piston rod 403 extending outside the sealing cylinder 401 is fixedly connected to the transmission assembly 307. The air inlet pipe 404 is fixed to the upper side of the sealing cylinder 401 through a one-way valve. The air outlet pipe 405 is fixed to the lower side of the sealing cylinder 401 through a one-way valve. The air blowing component 406 is obliquely opposite the anti-slip plate 306 on the gripper 305. A retraction component 407 is also provided between the transmission assembly 307 and the air blowing component 406.

[0042] The air blowing component 406 includes an air supply pipe 4061, an air outlet nozzle 4062, and a connecting hose 4063. The air supply pipe 4061 is fixedly connected to the air outlet pipe 405 through the connecting hose 4063. Multiple air outlet nozzles 4062 are arrayed at the bottom of the air supply pipe 4061. The end of the third connecting rod 4074 away from the fixing block 4073 is fixedly connected to the air supply pipe 4061.

[0043] Specifically, when the two grippers 305 move closer to each other, that is, during the gripping action, the first connecting plate 302 and the transmission assembly 307 drive the piston rod 403 to slide at the end of the sealing cylinder 401, and then drive the piston block 402 to slide inside the sealing cylinder 401. At this time, the piston block 402 will draw air into the sealing cylinder 401 through the air intake pipe 404 for storage. When the two grippers 305 move away from each other, that is, during the releasing action, the first connecting plate 302 and the transmission assembly 307 drive the piston rod 403 to slide at the end of the sealing cylinder 401, and then drive the piston block... 402 slides inside the sealing cylinder 401. At this time, the piston block 402 will discharge the air stored in the sealing cylinder 401 into the air supply pipe 4061 through the air outlet pipe 405, and then spray it out through multiple air outlet nozzles 4062, thereby uniformly blowing air to clean the gripper 305 that has just come into contact with the non-woven fabric. This can quickly and timely clean the dust, impurities and other contaminants on the gripping unit 3, avoiding the presence of contaminants that reduce the gripping accuracy and stability of the gripping unit 3. Moreover, the cleaning action is completed during the release of the gripper 305, making the cleaning relatively quick and convenient. There is no need for other electrical control, which reduces the cost required for cleaning.

[0044] Example 2: Please refer to Figure 6 and Figure 7 This embodiment further explains the first embodiment, the difference being that the slide 304 and guide rail 303 are optimized.

[0045] Specifically, the lubrication unit 5 includes an oil tank 501, a third connecting plate 502, and an oil supply pipe 503. One side of the oil tank 501 is fixed to the top of the double-acting cylinder 301 via the third connecting plate 502. One end of the oil supply pipe 503 is connected to the bottom of the oil tank 501, and the other end is fixed with an oil injection cylinder 504. A U-shaped plate 505 is fixed to the outside of the oil injection cylinder 504, and the bottom of the U-shaped plate 505 is fixed to the guide rail 303. The oil replenishment unit 6 is movably installed at the bottom of the oil injection cylinder 504. An oil outlet pipe 506 is fixedly connected to the bottom of the oil injection cylinder 504. An oil-absorbing sponge 507 is fixed to one end of the oil outlet pipe 506, and the oil-absorbing sponge 507 is fixed to one end of the guide rail 303.

[0046] Meanwhile, the oil replenishment unit 6 includes a plug 601, a valve stem 602, a valve plate 603, an annular plate 604, and a return spring 605. The plug 601 is fixed to the inner bottom of the oil supply pipe 503. The plug 601 has an oil passage hole 606 that is compatible with the valve plate 603. The valve stem 602 is fixed to the bottom of the valve plate 603. One end of the valve stem 602 away from the valve plate 603 is slidably connected to the bottom of the oil filling cylinder 504. The annular plate 604 is fixedly sleeved on the outer side of the valve stem 602. One end of the return spring 605 is fixed to the bottom of the annular plate 604, and the other end is fixed to the inner bottom of the oil filling cylinder 504. A top block 607 is fixed to one end of the valve stem 602 that extends out of the oil filling cylinder 504.

[0047] It should be noted that: Please refer to Figure 5 A fourth connecting rod 609 is fixed on the second connecting plate 3072. A push block 6010 is fixed at one end of the fourth connecting rod 609 away from the second connecting plate 3072. The push block 6010 is a right trapezoidal shape and has a slope on one side, so that it can contact the top block 607 and make it move upward.

[0048] Specifically, the continuous sliding between the slide block 304 at the top of the gripper 305 and the guide rail 303 will cause wear. To reduce wear, the fourth connecting rod 609 can be moved together with the second connecting plate 3072 during its movement. The fourth connecting rod 609 drives the push block 6010 to move, the push block 6010 drives the top block 607 to move upward, and the top block 607 drives the valve stem 602 and the valve plate 603 to move upward, so that the valve plate 603 moves out of the oil passage hole 606, opening the upper and lower sides of the block 601. That is, the lubricating oil in the oil supply pipe 503 can flow through the oil passage hole 606. The lubricant enters the oil filling cylinder 504 and flows through the oil outlet pipe 506 to the oil-absorbing sponge 507, gradually wetting the oil-absorbing sponge 507. As the gripper 305 releases the non-woven fabric, one side of the slide block 304 moves away from the guide rail 303, thereby driving the push block 6010 to move out from under the top block 607. Under the reset action of the return spring 605, the valve plate 603 blocks the oil passage hole 606 again, thereby blocking the block 601. The lubricant in the oil supply pipe 503 no longer enters the oil filling cylinder 504, thus stopping the oil filling action.

[0049] Also noteworthy is that you should refer to Figure 2 A pressure block 608 is fixed at one end of the slide block 304 near the first connecting plate 302. The slide block 304 will drive the pressure block 608 to move. When the pressure block 608 comes into contact with the oil-absorbing sponge 507 which is soaked in lubricating oil, it will squeeze out the lubricating oil in the oil-absorbing sponge 507. This will spread the lubricating oil into the sliding groove on the upper side of the slide block 304, thereby forming a lubricating oil channel in the sliding path of the slide block 304 and the guide rail 303, which will achieve a better lubrication effect on the guide rail 303 and the slide block 304.

[0050] Example 3: Please refer to Figure 4 and Figure 5 This embodiment further illustrates other embodiments, with the difference being the optimization of the air blowing component 406.

[0051] Specifically, the transmission assembly 307 includes a first connecting rod 3071, a second connecting plate 3072, a rack 3073, a drive gear 3074, and a driven gear 3075. The first connecting rod 3071 is fixed to one end of the first connecting plate 302, the second connecting plate 3072 is fixed to the end of the first connecting rod 3071 away from the first connecting plate 302, the rack 3073 is fixed to the other end of the second connecting plate 3072, the piston rod 403 is fixed to one end of the rack 3073, the drive gear 3074 meshes with the rack 3073, both ends of the central shaft of the drive gear 3074 are rotatably connected to limit plates 3076, one end of the limit plate 3076 is fixed to the outer wall of the double-acting cylinder 301, the driven gear 3075 meshes with the drive gear 3074, and the driven gear 3075 is connected to the retraction component 407.

[0052] The retraction component 407 includes a threaded cylinder 4071, a threaded column 4072, a fixing block 4073, and a third connecting rod 4074. The threaded cylinder 4071 is rotatably connected to the limiting plate 3076. The driven gear 3075 is fixedly sleeved with the threaded cylinder 4071. The threaded column 4072 is threadedly connected to the threaded cylinder 4071. The fixing block 4073 is fixed at the bottom of the threaded column 4072. One end of the third connecting rod 4074 is fixedly connected to the fixing block 4073, and the other end is fixedly connected to the air blowing component 406. An end plate 4075 is fixed to the top of the threaded column 4072. One end of the end plate 4075 is slidably sleeved with the limiting rod 4076. The bottom end of the limiting rod 4076 is fixed on the limiting plate 3076.

[0053] Specifically, when the gripper 305 performs the gripping action on the non-woven fabric, the rack 3073 drives the drive gear 3074 to rotate, the drive gear 3074 drives the driven gear 3075 to rotate, and the driven gear 3075 drives the threaded cylinder 4071 to rotate, thereby driving the threaded column 4072 to move upward, and driving the third connecting rod 4074 and the air blowing component 406 to move upward, preventing the non-woven fabric roll and the air blowing component 406 from colliding and interfering during the gripping process, so that the gripper 305 can smoothly grip the non-woven fabric; when the gripper 305 releases, the threaded column 4072 moves downward, driving the air blowing component 406 to move downward. At this time, gas will be ejected from the air nozzle 4062 of the air blowing component 406, so that the airflow will blow from top to bottom, expanding the range of airflow and improving the cleaning effect.

[0054] In this solution, an automatic palletizing device for a nonwoven fabric intelligent production line includes the following steps:

[0055] When the robotic arm 2 moves to the discharge end of the conveyor 1, the two grippers 305 move closer to the non-woven fabric roll on the conveyor 1 by moving the robotic arm 2 downward. Then, the double-acting cylinder 301 drives the two slides 304 and the two grippers 305 to move closer to each other, thereby clamping the non-woven fabric roll. After clamping, the robotic arm 2 moves upward and the base rotates 90 degrees to transport the clamped roll to one side. Then the robotic arm 2 moves downward to the stacking position and releases the two grippers 305, thereby automatically picking up and placing the non-woven fabric roll. By continuing to follow the above steps, batches of non-woven fabric rolls can be stacked in a regular manner.

[0056] When the two grippers 305 move closer together, that is, during the gripping action, the piston rod 403 can be driven to slide at the end of the sealing cylinder 401 via the first connecting plate 302 and the transmission assembly 307, and then the piston block 402 can be driven to slide inside the sealing cylinder 401. At this time, the piston block 402 will draw air into the sealing cylinder 401 through the air intake pipe 404 for storage. When the two grippers 305 move away from each other, that is, during the releasing action, the first connecting plate... 302 and transmission assembly 307 drive piston rod 403 to slide at the end of sealing cylinder 401, and then drive piston block 402 to slide inside sealing cylinder 401. At this time, piston block 402 will discharge the air stored in sealing cylinder 401 into air supply pipe 4061 through air outlet pipe 405, and then spray it out through multiple air outlet nozzles 4062, so as to uniformly blow air to clean the gripper 305 that has just come into contact with non-woven fabric, thereby quickly cleaning away dust, impurities and other contaminants from gripping unit 3.

[0057] Furthermore, during the movement of the second connecting plate 3072, the fourth connecting rod 609 moves along with it. The fourth connecting rod 609 moves the push block 6010, which in turn moves the top block 607 upward. The top block 607 then moves the valve stem 602 and the valve plate 603 upward, causing the valve plate 603 to move out of the oil passage 606. This opens up the upper and lower sides of the block 601, allowing the lubricating oil in the oil supply pipe 503 to enter the oil injection cylinder 504 through the oil passage 606. Finally, the oil flows along the oil outlet pipe 506 to the oil-absorbing sponge 507, gradually wetting the oil-absorbing sponge 507. When the pressure block 608 comes into contact with the oil-absorbing sponge 507, it will squeeze out the lubricating oil in the oil-absorbing sponge 507. This will spread the lubricating oil into the sliding groove on the upper side of the slide block 304, thereby forming a lubricating oil channel in the sliding path of the slide block 304 and the guide rail 303, which will achieve a better lubrication effect on the guide rail 303 and the slide block 304.
