[0027] Specific operation as follows, film bag transfer assembly 3 is provided with two, and two film bag transfer assembly 3 between the conveying belt for conveying film bag to sealing machine, film bag transfer assembly 3 between alternately from the conveying belt loading end two sides of the film bag and place it on the conveying belt, film bag is stacked and piled, when the electric trolley 2 carries film bag transfer assembly 3 to the film bag directly above, electric lifting rod 301 downwardly extends so that Bernoulli chuck 307 drops to the film bag surface, at this time, high-definition camera captures the film bag edge image, the image is transmitted to the analysis equipment for angle deviation detection, to determine whether the film bag has angle deviation, the angle deviation refers to whether the film bag side is perpendicular or parallel to the sealing machine, if not perpendicular or parallel indicates that there is angle deviation;

[0028] After the Bernoulli chuck 307 adsorbs the uppermost film bag, based on the angle deviation result output by the analysis equipment, the servo motor 302 adjusts the output direction and angle through the internal encoder, so that the servo motor 302 drives the plate body 303 to carry the Bernoulli chuck 307 to rotate based on the angle deviation of the adsorbed film bag, so that the angle deviation of the film bag is eliminated;

[0029] Wherein in the adsorption film bag, based on the size specification of film bag, the interval between Bernoulli chuck 307 can be adjusted by the extension of first electric telescopic rod 304 and second electric telescopic rod 306, so that Bernoulli chuck 307 can adsorb the position of the film bag edge angle deviation of different size specifications, and the installation rod 309 is electrically controlled to slide on the bottom of the frame slide rail 308, based on the size specification of film bag, the installation rod 309 is adjusted by sliding to make the film bag edge side always in the capture range of high-definition camera, and the distance between the installation rod 309 is obtained by distance sensor in real time, so that the distance between the installation rod 309 is adapted to the size of the film bag;

[0030] Based on the above description, the interval between Bernoulli chuck 307 can be adjusted by the extension of first electric telescopic rod 304 and second electric telescopic rod 306 when adsorbing film bag, so that Bernoulli chuck 307 can adapt to film bag of different size specifications, and based on the film bag edge image captured by high-definition camera and angle deviation detection, the servo motor 302 adjusts the output direction and angle through the internal encoder based on the angle deviation output result, to drive Bernoulli chuck 307 to rotate, so that the angle deviation of the film bag is eliminated, thereby facilitating the film bag sealing part to be consistent with the preset part, so as to ensure the sealing quality.

[0031] As Figures 1-5As shown, the auxiliary separation assembly 4 comprises a reciprocating pressing structure 401, and the side of the reciprocating pressing structure 401 is fixedly connected with the end of the second electric telescopic rod 306, and the bottom movable end of the reciprocating pressing structure 401 is fixedly connected with four reference right angle plates 402, the height of the reference right angle plate 402 is below the bottom of the Bernoulli chuck 307, and the reference right angle plate 402 is located in the shooting range of the high-definition camera, the surface of the reference right angle plate 402 is provided with a gas transmission box 403, the side of the gas transmission box 403 is provided with a lifting end 404, the top of the gas transmission box 403 is connected with the outlet of the two-way air pump through a pipeline, the bottom of the lifting end 404 is provided with a stress pressing plate 405, one end of the stress pressing plate 405 is fixedly connected with a hinge shaft 406, the hinge shaft 406 is rotatably connected with the surface of the reference right angle plate 402, and the bottom of the end of the hinge shaft 406 away from the stress pressing plate 405 is fixedly connected with an adjusting plate 407, the surface of the adjusting plate 407 is provided with a suction pipe 408, and the suction pipe 408 is connected with the inlet of the suction pump through a pipeline, and the bottom of the adjusting plate 407 is uniformly provided with a negative pressure hole 409.

[0032] Specific operation is as follows: when the Bernoulli chuck 307 is lowered to adsorb the film bag, the reference right angle plate 402 is first in contact with the surface of the film bag and is compacted, and under the subsequent downward pressure, the bottom movable end of the reciprocating pressing structure 401 is upwardly retracted, the structure of the reciprocating pressing structure 401 is consistent with the structure principle of the ball pen cap, after the first force is applied to the movable end to retract upwardly, the reciprocating pressing structure 401 is locked, at this time, the Bernoulli chuck 307 adsorbs the film bag, and the reference right angle plate 402 is attached to the upper surface of the film bag, at this time, the reference right angle plate 402 is located in the shooting range of the high-definition camera, and before each lowering, the Bernoulli chuck 307 is reset by the servo motor 302 to make the angle suitable for the sealing machine;

[0033] Therefore, when the reference right angle plate 402 is lowered to be attached to the surface of the film bag, the side of the reference right angle plate 402 is parallel or perpendicular to the sealing machine, and the reference right angle plate 402 is used as a reference to accurately analyze the angle deviation of the film bag by the equipment;

[0034] When the reference right angle plate 402 is lowered to be attached to the surface of the film bag, the bottom surface of the adjusting plate 407 is also attached to the surface of the film bag, and when the two-way air pump extracts the gas in the cavity of the Bernoulli chuck 307 to adsorb the film bag, the extracted gas is injected into the gas transmission box 403 to make the lifting end 404 extend downwardly, so as to press the stress pressing plate 405 downwardly, and the hinge shaft 406 drives the adjusting plate 407 to rotate slightly upwardly by an angle of 3-5°, and when the adjusting plate 407 is not upwardly tilted, the suction pump generates negative pressure at the negative pressure hole 409 through the suction pipe 408 to adsorb the side of the film bag;

[0035] When the adjusting plate 407 rotates and tilts slightly, the side of the film bag tilts up due to being attracted, thus separating from the side of the lower film bag. After the film bag is put down, the gas inside the gas transmission box 403 returns to the Bernoulli suction cup 307. At this time, the film bag is released and the adjusting plate 407 returns to the horizontal position, so that the film bag can be placed flat on the conveyor belt surface and the side of the film bag is prevented from folding.

[0036] The right-angle plate 402 is attached to the surface of the film bag and comes into contact with the surface of the conveyor belt. At this time, the force generated by the contact presses the movable end upward for the second time, causing the reciprocating pressing structure 401 to unlock it. Then, during the process of Bernoulli suction cup 307 lifting and resetting, the movable end extends downward and resets, so as to prepare for the next operation.

[0037] Based on the above description, when detecting the angle deviation of the film bag, the present invention uses a reference right-angle plate 402 as a reference object to measure the angle between the side of the film bag and the side of the reference right-angle plate 402. This angle is the specific angle deviation index, thereby reducing the difficulty of angle deviation detection and improving detection accuracy. When the bidirectional air pump extracts gas from the Bernoulli suction cup 307 to adsorb the film bag, the extracted gas is injected into the gas transmission box 403 to push the lifting end 404, thereby linking the adjustment plate 407 to tilt up. The adjustment plate 407, together with the air pump and the negative pressure hole 409 at its bottom, can adsorb the side of the film bag and tilt up accordingly during the tilting process, thereby facilitating the separation between the upper and lower film bags and preventing the upper and lower film bags from being transferred simultaneously due to adhesion.

[0038] like Figures 1-6 As shown, a laser rangefinder 5 is provided on the side of the electric trolley 2, and the laser rangefinder 5 is used to measure the distance between the film bag transfer assembly 3 and the end of the slide rail frame 1 in real time. A transmission cleaning assembly 6 is provided above the laser rangefinder 5, and the transmission cleaning assembly 6 includes a damping shaft 601. A first bevel gear 602 is fixed to the end of the damping shaft 601, and a second bevel gear 603 is meshed on the top of the first bevel gear 602. A transmission gear 604 is fixed to the top of the second bevel gear 603, and a rack 605 is meshed on the side of the transmission gear 604. The end of the damping shaft 601 away from the first bevel gear 602 is connected to the side of the electric trolley 2, and the top of the transmission gear 604 is connected to the side of the electric trolley 2 through a bracket. The rack 605 is fixed on both sides of the surface of the slide rail frame 1. A cleaning brush 606 is provided on the surface of the damping shaft 601, and the side of the cleaning brush 606 passes through the detection end face of the laser rangefinder 5 during the rotation of the damping shaft 601.

[0039] Specific operation as follows, the laser range finder 5 real-time measurement of the distance between the film bag transfer assembly 3 and the end of the slide rail frame 1 when the electric control trolley 2 moves, because the distance between the conveying belt, the stacked film bag to the end of the slide rail frame 1 is fixed, based on the measured distance can be calculated the real-time distance between the film bag transfer assembly 3 and the film bag, conveying belt, so that the film bag transfer assembly 3 accurately moves to the film bag above to take bag or moves to the conveying belt above to put bag;

[0040] When the electric control trolley 2 moves to the upper side of the stacked film bag, the transmission gear 604 rotates through the rack 605, at this time the transmission gear 604 drives the second bevel gear 603 to make the first bevel gear 602 rotate, the first bevel gear 602 drives the damping shaft 601 to rotate with the cleaning brush 606, so that the detection end face of the laser range finder 5 can be cleaned once in the process of the electric control trolley 2 passing through the rack 605 to the upper side of the film bag, so as to prevent the detection end face of the laser range finder 5 from being attached with dust to affect the ranging accuracy;

[0041] Based on the above description, when the two groups of film bag transfer assemblies 3 take turns to perform the bag taking operation through the electric control trolley 2, the translation of the electric control trolley 2 makes the transmission gear 604 rotate through the rack 605, and the damping shaft 601 rotates with the cleaning brush 606 through the second bevel gear 603 and the first bevel gear 602 to clean the detection end face of the laser range finder 5 once, so that the laser range finder 5 can accurately measure the distance every time the electric control trolley 2 translates, to ensure that the film bag transfer assembly 3 can accurately take and put the material.

[0042] In summary, the double-head automatic leveling feeding equipment with adjustable spacing is used, first, two film bag transfer assemblies 3 are provided, and a conveying belt for conveying the film bag to the sealing machine is arranged between the two film bag transfer assemblies 3, the film bag transfer assemblies 3 alternately take the film bag from both sides of the feeding end of the conveying belt and place it on the conveying belt, the film bags are stacked, when the electric control trolley 2 carrying the film bag transfer assembly 3 reaches the upper side of the film bag, the electric lifting rod 301 extends downward to make the Bernoulli suction cup 307 descend and adhere to the surface of the film bag;

[0043] When the film bag is adsorbed, based on the size specification of the film bag, the spacing between the Bernoulli suction cups 307 is adjusted through the extension and retraction of the first electric telescopic rod 304 and the second electric telescopic rod 306, so that the Bernoulli suction cup 307 can adsorb the position of the corner of the film bag of different size specifications, and the mounting rod 309 is electrically controlled to slide on the bottom of the frame slide rail 308, based on the size specification of the film bag, the position of the mounting rod 309 is adjusted through the sliding of the mounting rod 309, so that the side of the film bag is always within the capture range of the high-definition camera, and the spacing between the mounting rods 309 is obtained in real time through the distance measuring sensor, so that the spacing between the mounting rods 309 is adapted to the size of the film bag;

[0044] When the Bernoulli suction cup 307 is lowered to adsorb the film bag, the reference right-angle plate 402 is in contact with the surface of the film bag first and is compacted, and the bottom movable end of the reciprocating pressing structure 401 is retracted upward under the subsequent downward pressing force. The structure of the reciprocating pressing structure 401 is consistent with the structure principle of the cap of a ballpoint pen. After the movable end is retracted upward for the first time, the reciprocating pressing structure 401 locks the retracted movable end. At this time, the Bernoulli suction cup 307 adsorbs the film bag, and the reference right-angle plate 402 is attached to the four corner edges of the upper surface of the film bag. At this time, the reference right-angle plate 402 is located in the shooting range of the high-definition camera, and the Bernoulli suction cup 307 is reset before each lowering by the servo motor 302 so that the angle is adapted to the sealing machine.

[0045] Therefore, when the reference right-angle plate 402 is lowered and attached to the surface of the film bag, the side edges thereof are necessarily parallel or perpendicular to the sealing machine. Therefore, the reference right-angle plate 402 is used as a reference to accurately analyze the angle deviation of the film bag by the analysis equipment. After the uppermost film bag is adsorbed by the Bernoulli suction cup 307, the output angle deviation result of the analysis equipment is adjusted by the servo motor 302 through the internal encoder to adjust the output direction and angle. Thus, the film bag is rotated by the servo motor 302 driving the plate body 303 to carry the Bernoulli suction cup 307 based on the angle deviation of the adsorbed film bag, so that the angle deviation of the film bag is eliminated.

[0046] When the reference right-angle plate 402 is lowered and attached to the surface of the film bag, the bottom surface of the adjusting plate 407 is also attached to the surface of the film bag. When the gas in the cavity of the Bernoulli suction cup 307 is extracted by the two-way air pump to adsorb the film bag, the extracted gas is injected into the gas transmission box 403 to make the lifting end 404 extend downward, so that the stressed pressing plate 405 drives the hinged shaft 406 to rotate the adjusting plate 407 to be slightly raised by an angle of 3-5°. When the adjusting plate 407 is not raised, the air pump generates negative pressure at the negative pressure hole 409 through the air extraction pipe 408 to adsorb the side edges of the film bag.

[0047] When the adjusting plate 407 is slightly raised, the side edges of the film bag are also raised due to being adsorbed, so as to be separated from the side edges of the lower film bag. After the film bag is lowered, the gas in the gas transmission box 403 returns to the cavity of the Bernoulli suction cup 307. At this time, the film bag is loosened and the adjusting plate 407 is reset to be horizontal, so as to place the film bag flat on the surface of the conveying belt, avoiding the folding of the side edges of the film bag.

[0048] The reference right-angle plate 402 is attached to the surface of the film bag and is in contact with the surface of the conveying belt. At this time, the upward pressing force generated by the contact unlocks the reciprocating pressing structure 401. Then, the movable end is lowered and reset during the lifting and resetting of the Bernoulli suction cup 307, so as to prepare for the next operation.
