DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0026] Example

[0027] A material unloading mechanism of a laminating machine, such as Figure 1-3As shown, it includes a stacking device 51 arranged on the frame 10 of the stacking machine for placing glass stacks, a paper rack device 52 for placing papers, and a picking device 53 for sucking the glass on the feeding mechanism 40 of the stacking machine and the papers on the paper rack device 52 into the stacking device 51.

[0028] Specifically, when the material taking device 53 sucks the glass sheets on the feeding mechanism 40 of the stacking machine, the material taking device 53 places the sucked paper in the stacking device 51; when the material taking device 53 places the sucked glass in the stacking device 51, the material taking device 53 sucks the paper in the paper rack device 52. The stacking device 51 is located between the paper rack device 52 and the feeding mechanism 40 of the stacking machine. Specifically, the feeding mechanism 40 of the stacking machine is a conveyor belt assembly.

[0029] After the feeding device 53 of the present invention sucks the glass sheets conveyed by the feeding mechanism 40 of the stacking machine, the glass sheets are further conveyed to the top of the stacking device 51 and the glass sheets are placed in the stacking device 51. When the feeding device 53 sucks the glass sheets, the feeding device 53 puts the paper sucked from the paper rack device 52 into the stacking device 51. When the feeding device 53 puts the glass sheets into the stacking device 51, the feeding device 53 sucks the paper from the paper rack device 52, so that the paper is placed between adjacent glass sheets to isolate the glass sheets, protect the glass sheets, avoid the friction between adjacent glass sheets and cause the surface wear of the glass sheets, and the stacking efficiency is high.

[0030] Among them, the stacking device 51 includes a first support plate 511 for carrying glass stacking, a glass lifting assembly 512 arranged at the bottom of the first support plate 511 for driving the first support plate 511 to rise and fall, and an alignment assembly 513 arranged on the frame 10 and located around the first support plate 511 for aligning the four sides of the glass stacking.

[0031] By setting the glass lifting assembly 512, the height of the first support plate 511 can be adjusted according to the stacking height of the glass sheets. When there are fewer glass sheets stacked on the first support plate 511, the thickness of the stacked glass sheets is smaller. In order to facilitate the material taking device 53 to put the glass sheets on the first support plate 511, the first support plate 511 is driven to rise to a higher position by the glass lifting assembly 512, so that the material taking device 53 can put the glass sheets on the first support plate 511 without excessive downward movement, which is conducive to improving the stacking efficiency. When there are more glass sheets stacked on the first support plate 511, the thickness of the stacked glass sheets is larger. The first support plate 511 is driven down by the glass lifting assembly 512, so that the topmost glass sheet on the first support plate 511 always keeps a certain distance from the material taking device 53, so that the material taking device 53 can continue to stack glass sheets on the first support plate 511, which is conducive to increasing the stacking amount of glass sheets, so that the stacking machine can stack more glass sheets at one time. The arrangement of the alignment component 513 enables the alignment component 513 to automatically align the four sides of the glass sheets continuously when the glass sheets are stacked, thereby ensuring that the edges of the stacked glass sheets remain aligned, making it easier to pack the stacked glass sheets later.

[0032] The glass lifting assembly 512 includes a glass lifting screw 5121 , at least two glass lifting guide rods 5122 , a glass lifting nut 5123 , a glass lifting connecting block 5124 , a glass lifting motor 5125 and a glass lifting fixing frame 5126 . The glass lifting fixed frame 5126 is fixedly arranged at the bottom of the frame 10, the glass lifting motor 5125 is fixedly arranged at the bottom of the glass lifting fixed frame 5126, the upper end of the glass lifting screw rod 5121 is rotatably connected to the top of the glass lifting fixed frame 5126, the lower end of the glass lifting screw rod 5121 is fixedly connected to the output shaft of the glass lifting motor 5125, the glass lifting nut member 5123 is arranged on the glass lifting screw rod 5121 and is threadedly connected to the glass lifting screw rod 5121, the glass lifting connecting block 5124 is fixedly connected to the glass lifting nut member 5123, the lower end of the glass lifting guide rod 5122 is fixedly connected to the glass lifting connecting block 5124, the upper end of the glass lifting guide rod 5122 passes through the frame 10 and is fixedly connected to the first support plate 511, and the glass lifting guide rod 5122 is slidably connected to the frame 10.

[0033] When the glass lifting assembly 512 drives the first support plate 511 to rise and fall, the glass lifting motor 5125 drives the glass lifting screw rod 5121 to rotate. Since the glass lifting nut 5123 is limited by the glass lifting guide rod 5122, when the glass lifting screw rod 5121 rotates, the glass lifting nut 5123 can only rise and fall along the glass lifting screw rod 5121 but cannot rotate with the glass lifting screw rod 5121, thereby causing the first support plate 511 to move up and down under the action of the glass lifting nut 5123 and the glass lifting guide rod 5122. The cooperation between the glass lifting nut 5123 and the glass lifting screw rod 5121 makes the movement accuracy of the first support plate 511 higher, and the first support plate 511 can be accurately adjusted to a suitable height, thereby preventing the first support plate 511 from being damaged due to the inappropriate height of the glass sheet or paper being broken or squeezed when the material taking assembly places the glass sheet or paper on the first support plate 511; on the other hand, the cooperation between the glass lifting nut 5123 and the glass lifting guide rod 5122 makes the movement of the first support plate 511 more stable, and the first support plate 511 is less likely to vibrate, thereby preventing the glass sheets on the first support plate 511 from colliding with each other and being damaged.

[0034] Among them, the alignment component 513 includes at least four alignment plates 5131 and alignment driving members 5132 respectively used to drive the alignment plates 5131 to move, the alignment plates 5131 are slidably arranged on the frame 10, at least four of the alignment plates 5131 are respectively arranged at positions close to the four side edges of the first support plate 511, two relatively arranged alignment plates 5131 are parallel to each other, and two adjacent alignment plates 5131 are perpendicular to each other, and the alignment driving member 5132 is used to drive the alignment plates 5131 to move in a direction close to or away from the first support plate 511, the upper surface of the first support plate 511 is less than or equal to the surface area of ​​the glass sheet, specifically, the alignment driving member 5132 is an alignment cylinder, the telescopic shaft of the alignment cylinder is connected to the side of the alignment plate 5131 away from the first support plate 511, and the alignment driving member 5132 is arranged on the frame 10.

[0035] When the alignment component 513 is used to align the stacked glass sheets, the multiple alignment vertical plates 5131 are driven by the multiple alignment driving members 5132 to move toward the direction close to the first support plate 511, and the two opposite alignment vertical plates 5131 are simultaneously pushed to align the two opposite sides of the glass stack. The four alignment vertical plates 5131 align the four sides of the glass stack.

[0036] The alignment assembly 513 further includes a sliding block 5133 disposed at the bottom of one of the alignment driving members 5132 near the long side of the glass sheet, a sliding guide rail 5134 disposed on the frame 10 and slidably matched with the sliding block 5133, and a translation cylinder 5135 for driving the sliding block 5133 to slide along the length direction of the sliding guide rail 5134. The length direction of the sliding guide rail 5134 is arranged in a direction parallel to the first support plate 511. The bottom of the sliding block 5133 is provided with a sliding groove (not shown) slidably matched with the sliding guide rail 5134. The telescopic shaft of the translation cylinder 5135 is fixedly connected to the sliding block 5133. Specifically, the sliding block 5133, the sliding guide rail 5134 and the translation cylinder 5135 are disposed on a side away from the material taking assembly.

[0037] Since the long side of the glass sheet is long, when the alignment plate 5131 aligns the positions of the two long sides of the glass sheet, the alignment plate 5131 may be narrow, so that the two long sides of the glass sheet cannot be aligned and are not neat. Therefore, the present invention provides a sliding block 5133 at the bottom of one of the alignment driving members 5132 close to the long side of the glass sheet, and drives the sliding block 5133 to slide by the translation cylinder 5135, so that when the glass stack on the first support plate 511 is aligned, the sliding block 5133 can be driven by the translation cylinder 5135. The alignment driving parts 5132 located on the two long sides of the glass sheet drive the alignment vertical plate 5131 to approach the glass stack, and then the sliding block 5133 and the alignment cylinder located on the sliding block 5133 are driven by the translation cylinder 5135 to move synchronously along the direction parallel to the first support plate 511, thereby driving the alignment vertical plate 5131 on this side to move along the direction parallel to the first support plate 511, and the movement of the alignment vertical plate 5131 on this side pushes the various positions of the long side of the glass stack on this side, so that the various positions of the long side of the glass stack are aligned.

[0038] The paper rack device 52 includes a paper rack body 521, a second support plate 522 disposed in the paper rack body 521 for carrying paper, and a paper lifting assembly 523 disposed at the bottom of the second support plate 522 for driving the second support plate 522 to rise and fall.

[0039] By setting the paper lifting component 523, the second support plate 522 can adjust its height according to the stacking height of the paper. When there are fewer papers stacked on the second support plate 522, the thickness of the stacked paper is smaller. In order to facilitate the material taking device 53 to take out the paper from the paper rack body 521, the paper lifting component 523 drives the second support plate 522 to rise to a higher position, so that the material taking device 53 can take out the paper from the paper rack body 521 without excessive downward movement, thereby improving the paper taking efficiency and further improving the stacking efficiency. When there are more papers stacked on the second support plate 522, the thickness of the stacked paper is larger. The paper lifting component 523 drives the second support plate 522 to descend, so that the paper rack body 521 can accommodate more papers, and thus the stacking machine can stack more glass sheets at one time.

[0040] Among them, the paper rack body 521 includes a base 5211, a fixed bottom plate 5212 fixed in the middle of the base 5211, and a surrounding plate 5213 arranged circumferentially along the fixed bottom plate 5212. Each of the surrounding plates 5213 is rotatably connected to one side of the fixed bottom plate 5212 with at least two positioning screws 5214, and the positioning screws 5214 are threadedly connected to the side of the fixed bottom plate 5212.

[0041] The present invention forms a paper rack body 521 for placing paper by enclosing a base 5211, a fixed bottom plate 5212 and a plurality of enclosures 5213, so that when paper is placed in the paper rack body 521, it is not easy to be scattered or fall off the second support plate 522 due to external wind, and the paper on the second support plate 522 can be protected from being hit by external objects and falling off the second support plate 522. The present invention provides at least two positioning screws 5214 on each enclosure 5213, so that the enclosure 5213 will not be tilted or shifted when it is installed on the fixed bottom plate 5212, which is conducive to improving the structural stability of the paper rack body 521. The enclosure 5213 of the present invention is threadedly connected to the fixed bottom plate 5212 by using a positioning screw 5214, so that the enclosure 5213 can adjust the distance between the enclosure 5213 and the positioning material rack bottom plate by rotating the positioning screw 5214, thereby adjusting the distance between the upper ends of multiple enclosures 5213, thereby adjusting the size of the upper end opening of the paper rack body 521, and by adjusting multiple enclosures 5213 to a position farther away from the fixed bottom plate 5212, thereby making the upper end opening of the paper rack body 521 larger, so that it is convenient for the staff to place paper on the second support plate 522 in the paper rack body 521. After placing the paper, the distance between the enclosures 5213 can be reduced by rotating the positioning screw 5214 in the opposite direction, thereby making the size of the paper rack body 521 compatible with the size of the paper. The setting of the positioning screw 5214 also enables the paper rack body 521 to be suitable for placing papers of different sizes, so that the paper rack assembly has a wider range of applications.

[0042] A limiting block 5215 is disposed at the upper end of the enclosure 5213 , and a side of the limiting block 5215 close to the inside of the paper holder body 521 is located in the region of the upper opening of the paper holder body 521 .

[0043] The stop block 5215 has the function of preventing the paper below from coming out of the paper body along with the paper sucked by the material taking component, ensuring that the material taking component only takes away one paper each time, which is helpful to reduce paper waste.

[0044] Among them, each of the limit blocks 5215 is provided with at least two strip holes 5216, and the upper end of each of the enclosure plates 5213 is threadedly connected with a limit screw corresponding to the strip holes 5216 on the limit block 5215, and a limit nut 5218 is provided on the top of the limit screw, and the limit screw is slidably connected with the strip hole 5216, and the limit nut 5218 is located at the top of the limit block 5215.

[0045] By providing a strip hole 5216 on the limit block 5215 and providing a limit screw on the enclosure 5213, the limit screw is rotated so that the limit nut 5218 no longer presses the limit block 5215, thereby making the position of the limit block 5215 adjustable, thereby making the limit block 5215 adjustable to the position of the upper opening of the paper rack body 521 according to the size of the paper, so that the limit block 5215 can better limit the paper in the paper rack body 521. On the other hand, when it is necessary to add paper to the paper rack body 521, the limit block 5215 can be moved away from the upper opening of the paper rack body 521 to prevent the limit block 5215 from blocking the paper from being put into the paper rack body 521. When it is necessary to fix the limit block 5215, it is only necessary to rotate the limit screw so that the limit nut 5218 cooperates with the upper end of the enclosure 5213 to press the limit block 5215, thereby achieving the purpose of fixing the limit block 5215.

[0046] The outside of the paper rack body 521 is provided with a wind knife 5219 for separating adjacent papers. When the material taking component sucks the paper, the wind knife 5219 blows air to the upper opening of the paper rack body 521 to separate the adjacent papers, further ensuring that the paper below will not be sucked out of the paper body along with the paper sucked by the material taking component, ensuring that the material taking component only takes away one paper at a time, which is more conducive to reducing paper waste. When in use, the wind knife 5219 is connected to an external air duct so that the external air duct conveys gas to the wind knife 5219 to achieve the purpose of blowing air from the wind knife 5219.

[0047] Among them, the blowing nozzle of the wind knife 5219 is flat and horizontally arranged, which is more conducive to separating adjacent papers.

[0048] The paper lifting assembly 523 includes a paper lifting screw 5231 , at least two paper lifting guide rods 5232 , a paper lifting nut 5233 , a paper lifting connecting block 5234 , a paper lifting motor 5235 and a paper lifting fixing frame 5236 . The paper lifting fixed frame 5236 is fixedly arranged at the bottom of the frame 10, the paper lifting motor 5235 is fixedly arranged at the bottom of the paper lifting fixed frame 5236, the upper end of the paper lifting screw rod 5231 is rotatably connected to the top of the paper lifting fixed frame 5236, the lower end of the paper lifting screw rod 5231 is fixedly connected to the output shaft of the paper lifting motor 5235, the paper lifting nut member 5233 is arranged on the paper lifting screw rod 5231 and is threadedly connected to the paper lifting screw rod 5231, the paper lifting connecting block 5234 is fixedly connected to the paper lifting nut member 5233, the lower end of the paper lifting guide rod 5232 is fixedly connected to the paper lifting connecting block 5234, the upper end of the paper lifting guide rod 5232 passes through the frame 10 and is fixedly connected to the second support plate 522, and the paper lifting guide rod 5232 is slidably connected to the frame 10.

[0049] When the paper lifting assembly 523 drives the second support plate 522 to rise and fall, the paper lifting motor 5235 drives the paper lifting screw rod 5231 to rotate. Since the paper lifting nut 5233 is limited by the paper lifting guide rod 5232, when the paper lifting screw rod 5231 rotates, the paper lifting nut 5233 can only rise and fall along the paper lifting screw rod 5231 but cannot rotate with the paper lifting screw rod 5231, thereby causing the second support plate 522 to rise and fall under the action of the paper lifting nut 5233 and the paper lifting guide rod 5232. The cooperation between the paper lifting nut 5233 and the paper lifting screw rod 5231 makes the movement accuracy of the second support plate 522 higher, and the second support plate 522 can be accurately adjusted to a suitable height, thereby preventing the second support plate 522 from being unable to smoothly remove the paper due to an inappropriate height. On the other hand, the cooperation between the paper lifting nut 5233 and the paper lifting guide rod 5232 makes the movement of the second support plate 522 more stable, and the second support plate 522 is less likely to vibrate, thereby preventing the paper on the second support plate 522 from being disturbed or falling off the second support plate 522.

[0050] The feeding mechanism 40, the stacking device 51 and the support device are arranged in sequence along a straight line, and the picking device 53 includes a support frame 531, a first picking lifting assembly 532, a second picking lifting assembly 533, a picking translation assembly 534, a first picking assembly 535, and a second picking assembly 536.

[0059] Working process:

[0060] The glass piece moves towards the direction approaching the unloading mechanism 50 under the action of the feeding mechanism 40. When the glass piece moves to the position close to the unloading mechanism 50, the first material picking component 535 moves to the top of the feeding mechanism 40, and the second material picking component 536 moves to the top of the stacking device 51 at this time, and the first material picking lifting driving member 5323 is started. The first material picking lifting driving member 5323 drives the first material picking lifting sliding block 5322 and the first material picking component 535 to move downward synchronously until the first material picking nozzle 5352 moves to contact the glass piece on the feeding mechanism 40. The air pump connected to the first material picking nozzle 5352 draws air, so that the air pressure between the first material picking nozzle 5352 and the glass piece is less than the atmospheric pressure, so that the glass piece is sucked up by the first material picking nozzle 5352, and then the first material picking lifting driving member 5323 drives the first material picking lifting sliding block 5322, the first material picking component 535 and the glass piece to rise synchronously, so that the glass piece leaves the feeding mechanism 40, and then further passes through The material picking translation driving member 5343 drives the material picking translation sliding block, the first material picking lifting assembly 532, the first material picking assembly 535, the glass sheet, the second material picking lifting assembly 533 and the second material picking assembly 536 to move in the direction away from the feeding mechanism 40 until the first material picking assembly 535 moves to above the stacking device 51. At this time, the second material picking assembly 536 moves to above the paper rack device 52, and the first material picking lifting driving member 5323 is started again to drive the first material picking lifting sliding block 5322 to move downward, thereby causing the first material picking lifting sliding block 5322 to drive the first material picking assembly 535 and the glass sheet to move downward until the glass sheet moves to the first support plate 511. The air pump connected to the first material picking nozzle 5352 slowly pumps gas to the first material picking nozzle 5352, so that the pressure between the first material picking nozzle 5352 and the glass sheet is equal to or greater than the atmospheric pressure, thereby separating the first material picking nozzle 5352 and the glass sheet, and placing the glass sheet on the first support plate 511.When the first material picking lifting driving member 5323 drives the first material picking lifting slide block 5322 to move downward, the second material picking lifting driving member 5333 simultaneously drives the second material picking lifting slide block 5332 to move downward, thereby driving the second material picking assembly 536 to move downward, until the second material picking suction nozzle 5362 moves to fit the paper on the second supporting plate 522, and the air pump connected to the second material picking suction nozzle 5362 draws air so that the gas pressure between the second material picking suction nozzle 5362 and the paper is less than the atmospheric pressure, thereby causing the paper to be sucked up by the second material picking suction nozzle 5362, and then passed through Under the driving action of the second material picking lifting driving member 5333, the paper leaves the paper holder device 52, and while the second material picking suction nozzle 5362 sucks up the paper, the wind knife 5219 blows air to the paper below the second suction nozzle to separate the paper, and under the action of the material picking translation driving member 5343, the second material picking assembly 536 sucks the paper and moves to the position of the stacking device 51, and places the paper on the glass sheet of the stacking device 51, and the second material picking assembly 536 moves again to the feeding mechanism 40 to suck up the glass sheet under the action of the material picking translation driving member 5343.
