Description

Technical Field

[0001] The present invention relates to the technical field of palletizing devices, and in particular to an automatic palletizing device for a non-woven fabric intelligent production line. Background Art

[0002] During the production process of non-woven fabrics, they often need to be transported and packaged in rolls. Most of the non-woven fabric stacking on the market requires manual operation, which is labor-intensive for workers. In addition, careless operation may damage the product and cause uneven placement.

[0003] In order to achieve fully automatic palletizing of non-woven fabric rolls, a robotic arm is usually used for palletizing on the production line. The opening and closing action of the clamp structure at the gripping end of the robotic arm, that is, the picking and placing action of the non-woven fabric rolls, can achieve an effect of automatic palletizing of the non-woven fabric rolls. However, in actual operation, when the clamps are operated in an environment without a protective cover, they are directly exposed to the air. Dust on the ground of the production line and debris (such as plastic particles) on the outside of the non-woven fabric rolls will adhere to the clamps as they move. The clamps of the robotic arm will inevitably be contaminated with dust, impurities and other pollutants. If they are not cleaned in time, these pollutants may reduce the clamping accuracy and stability of the clamps. In addition, since the clamps are in direct contact with the non-woven fabric rolls, the cleanliness of their surface will also directly affect the quality of the non-woven fabric.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts 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 non-woven fabric intelligent production line, comprising a conveyor 1 for conveying non-woven fabric rolls. A robotic arm 2 for automatically palletizing the non-woven fabric rolls is provided at one end of the conveyor 1. When in use, the rolled non-woven fabric rolls are conveyed to the discharge end by the conveyor 1, and then the non-woven fabric rolls are grabbed by the robotic arm 2. The grabbed non-woven fabric rolls are then stacked on one side, thereby realizing fully automatic palletizing of the non-woven fabric rolls.

[0037] The robot also includes: a gripping unit 3 installed at the front end of the robot arm 2, the gripping unit 3 is used to pick up and place the non-woven fabric, and a joint cleaning unit 4 is installed on the outside of the gripping unit 3, the joint cleaning unit 4 is used to clean the gripping end of the gripping unit 3. The designed joint cleaning unit 4 can perform cleaning in the process of picking up and placing the non-woven fabric by the gripping unit 3, thereby quickly removing dust, impurities and other pollutants from the gripping unit 3, thereby preventing the presence of pollutants from reducing 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 installed with an oil replenishing unit 6. During the operation of the clamping unit 3, the moving end of the clamping unit 3 can be automatically maintained through the cooperation of the lubrication unit 5 and the oil replenishing unit 6, thereby improving the service life of the clamping unit 3.

[0039] For further information, see Figure 2 and Figure 3 The clamping unit 3 includes a double-acting cylinder 301, a first connecting plate 302, a guide rail 303, a slide 304 and a clamping claw 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 clamping claw 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, and the two clamping claws 305 are fixed with anti-skid plates 306 on the sides close to each other, and a transmission assembly 307 is fixed at one end of the first connecting plate 302. One end of the joint cleaning unit 4 is connected to the transmission assembly 307. The lubrication unit 5 is arranged above the guide rail 303 and is used to automatically maintain the slide groove on the top of the slide 304.

[0040] Specifically, see Figure 1 and Figure 3 When the robot arm 2 moves to the discharge end of the conveyor 1, the two clamping claws 305 are moved close to the non-woven fabric roll on the conveyor 1 by the downward movement of the robot arm 2, and then the two slides 304 and the two clamping claws 305 are driven by the double-acting cylinder 301 to move closer to each other, thereby clamping the non-woven fabric roll. After clamping, the robot arm 2 moves up and the base rotates ninety degrees to transport the clamped roll to one side, and then the robot arm 2 moves down to the stacking position and releases the two clamping claws 305, thereby automatically picking up and placing the non-woven fabric roll. By continuing the above steps, batches of non-woven fabric rolls can be regularly stacked.

[0041] For further information, see 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 a blowing piece 406. The sealing cylinder 401 is fixed to the outside of the double-acting cylinder 301, the piston block 402 is slidably connected in the sealing cylinder 401, the piston rod 403 is fixed to one end of the piston block 402, and the end of the piston rod 403 extending out of 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, and the air outlet pipe 405 is fixed to the lower side of the sealing cylinder 401 through a one-way valve. The blowing piece 406 is obliquely opposite to the anti-slip plate 306 on the clamp 305, and a retracting piece 407 is also provided between the transmission assembly 307 and the blowing piece 406.

[0042] Among them, the blowing part 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. There are multiple air outlet nozzles 4062 distributed in an array at the bottom of the air supply pipe 4061. The third connecting rod 4074 is fixedly connected to the air supply pipe 4061 at one end away from the fixed block 4073.

[0043] Specifically, when the two clamping jaws 305 move toward each other, that is, when the clamping jaws 305 perform a clamping action, the piston rod 403 can be driven to slide at the end of the sealing cylinder 401 through the first connecting plate 302 and the transmission assembly 307, and then the piston block 402 can be driven to slide in the sealing cylinder 401. At this time, the piston block 402 will suck air into the sealing cylinder 401 through the air inlet pipe 404 for storage; when the two clamping jaws 305 move away from each other, that is, when the clamping jaws 305 perform a loosening action, the piston rod 403 can be driven to slide at the end of the sealing cylinder 401 through the first connecting plate 302 and the transmission assembly 307, and then the piston block 402 slides in 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, so as to evenly blow and clean the clamping claws 305 that have just come into contact with the non-woven fabric, and then quickly clean the dust, impurities and other pollutants in the clamping unit 3 in time, so as to avoid the presence of pollutants reducing the clamping accuracy and stability of the clamping unit 3; and the cleaning action will be completed in the process of loosening the clamping claws 305. The cleaning is relatively quick and convenient, and there will be no other electricity for 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, and the difference lies in optimizing the slide 304 and the guide rail 303.

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

[0046] At the same time, the oil replenishing unit 6 includes a block 601, a valve stem 602, a valve plate 603, an annular plate 604 and a return spring 605. The block 601 is fixed to the inner side of the bottom of the oil delivery pipe 503. The block 601 is provided with an oil hole 606 adapted to the valve plate 603. The valve stem 602 is fixed to the bottom of the valve plate 603. The 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 outside 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. The end of the valve stem 602 extending outside the oil filling cylinder 504 is fixed to a top block 607.

[0047] Please note: Please refer to Figure 5 A fourth connecting rod 609 is fixed on the second connecting plate 3072, and a push block 6010 is fixed on one end of the fourth connecting rod 609 away from the second connecting plate 3072. The push block 6010 is in the shape of a right-angled trapezoid, and one side of the push block 6010 has an inclined surface so that it can contact the top block 607 and cause it to move upward.

[0048] Specifically, continuous sliding between the slide 304 and the guide rail 303 at the top of the clamp 305 will cause wear. In order to reduce the wear, the fourth connecting rod 609 can be driven to move together during the movement of the second connecting plate 3072. The fourth connecting rod 609 drives the push block 6010 to move, and the push block 6010 drives the top block 607 to move upward. 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 hole 606, and the upper and lower sides of the block 601 are connected, that is, the lubricating oil in the oil pipe 503 can flow through the oil hole 606. The oil then flows into the oil filling cylinder 504 and finally flows along the oil outlet pipe 506 to the oil absorbing sponge 507, so that the oil absorbing sponge 507 is gradually soaked with lubricating oil. In the process of the clamping jaws 305 loosening the non-woven fabric, one side of the slide 304 will move away from the guide rail 303, thereby driving the push block 6010 to move out from the lower side of the top block 607, and under the reset action of the reset spring 605, the valve plate 603 is driven to block the oil hole 606 again, thereby blocking the blocking block 601. The lubricating oil in the oil delivery pipe 503 no longer enters the oil filling cylinder 504, and the oil filling action will be stopped.

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

[0050] Example 3: Please refer to Figure 4 and Figure 5 This embodiment further illustrates other embodiments, the difference being that the blowing member 406 is optimized.

[0051] Specifically, the transmission assembly 307 includes a first connecting rod 3071, a second connecting plate 3072, a rack 3073, a driving 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 driving gear 3074 is meshed with the rack 3073, both ends of the central axis of the driving gear 3074 are rotatably connected to the limiting plate 3076, one end of the limiting plate 3076 is fixed to the outer wall of the double-acting cylinder 301, the driven gear 3075 is meshed with the driving gear 3074, and the driven gear 3075 is transmission-connected to the retracting member 407.

[0052] Among them, the retraction part 407 includes a threaded barrel 4071, a threaded column 4072, a fixed block 4073 and a third connecting rod 4074, the threaded barrel 4071 is rotatably connected to the limit plate 3076, the driven gear 3075 is fixedly sleeved on the threaded barrel 4071, the threaded column 4072 is threadedly connected to the threaded barrel 4071, the fixed block 4073 is fixed to the bottom of the threaded column 4072, one end of the third connecting rod 4074 is fixedly connected to the fixed block 4073, and the other end is fixedly connected to the blowing part 406, the top of the threaded column 4072 is fixed with an end plate 4075, one end of the end plate 4075 is slidably sleeved on the limit rod 4076, and the bottom end of the limit rod 4076 is fixed on the limit plate 3076.

[0053] Specifically, when the clamping jaws 305 perform the clamping action on the non-woven fabric, the rack 3073 will drive the driving gear 3074 to rotate, the driving gear 3074 will drive the driven gear 3075 to rotate, and the driven gear 3075 will drive the threaded cylinder 4071 to rotate, thereby driving the threaded column 4072 to move upward, driving the third connecting rod 4074 and the blowing piece 406 to move upward, preventing the non-woven fabric roll and the blowing piece 406 from colliding and interfering during the clamping process, so that the clamping jaws 305 can smoothly clamp the non-woven fabric; and in the process of loosening the clamping jaws 305, the threaded column 4072 will move downward and drive the blowing piece 406 to move downward. At this time, gas will be ejected from the air outlet nozzle 4062 of the blowing piece 406, so that the air flow will blow from top to bottom, expanding the range of the air flow blowing and achieving better cleaning effect.

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

[0055] When the robot arm 2 moves to the discharge end of the conveyor 1, the two clamping claws 305 are moved close to the non-woven fabric roll on the conveyor 1 by the downward movement of the robot arm 2, and then the two slides 304 and the two clamping claws 305 are driven by the double-acting cylinder 301 to move closer to each other, thereby clamping the non-woven fabric roll. After clamping, the robot arm 2 is moved upward and the base is rotated ninety degrees to transport the clamped roll to one side. The robot arm 2 then moves down to the stacking position and releases the two clamping claws 305, thereby automatically picking up and placing the non-woven fabric roll. By continuing the above steps, batches of non-woven fabric rolls can be regularly stacked.

[0056] When the two clamping jaws 305 move toward each other, that is, when the clamping jaws 305 perform the clamping action, the first connecting plate 302 and the transmission assembly 307 can drive the piston rod 403 to slide at the end of the sealing cylinder 401, and then drive the piston block 402 to slide in the sealing cylinder 401. At this time, the piston block 402 will suck air into the sealing cylinder 401 through the air inlet pipe 404 for storage. When the two clamping jaws 305 move away from each other, that is, when the clamping jaws 305 perform the loosening 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 in 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, so as to evenly blow and clean the clamping claws 305 that have just come into contact with the non-woven fabric, thereby quickly and promptly cleaning the dust, impurities and other pollutants in the clamping unit 3;

[0057] In the process of the movement of the second connecting plate 3072, the fourth connecting rod 609 is driven to move together, 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 hole 606, and the upper and lower sides of the block 601 are connected, that is, the lubricating oil in the oil pipe 503 can enter the oil filling cylinder 504 through the oil hole 606. , and finally flows along the oil outlet pipe 506 to the oil absorbing sponge 507, so that the oil absorbing sponge 507 is gradually soaked with lubricating oil. When the pressing block 608 comes into contact with the oil absorbing sponge 507 soaked with lubricating oil, the lubricating oil in the oil absorbing sponge 507 will be squeezed out, which will smear the lubricating oil in the slide groove on the upper side of the slide 304, thereby forming a lubricating oil channel in the sliding path of the slide 304 and the guide rail 303, thereby achieving a better lubrication effect on the guide rail 303 and the slide 304.
