Description

Technical Field

[0001] The present invention relates to the technical field of packaging machines, and particularly relates to a fully automatic bag loading and bag tying integrated packaging machine. Background Art

[0002] In production and life, after consumers buy materials, they cannot use them up at one time. If the materials are stored exposed to the air, there will be problems such as volatilization, easy moisture absorption, and easy deterioration. The unused materials need to be sealed again. Tying them tightly with a rope is a relatively convenient, fast, and easy-to-open method. Therefore, manufacturers mostly use double-layer bags to hold materials. The inner layer bag is a plastic film bag, which plays a sealing role; the bag mouth of the inner layer bag is tied into a bundle to facilitate opening and repeated tying and sealing during use; the outer layer bag is wrapped outside the inner layer bag and is a woven bag, which plays a load-bearing and protective role. During the production process, the bag mouth of the inner layer bag needs to be tied tightly with a rope to achieve the sealing effect. One of the double-layer bag packaging methods requires gathering the bag mouth of the inner layer bag to form a cylindrical bundle and folding it by 180 degrees, and then tying it tightly with a rope to increase the sealing performance. The tied bag mouth of the inner layer bag is placed inside the bag mouth of the outer layer bag, and the outer layer bag is automatically sewn with a sewing machine to complete the packaging.

[0003] The current sewing machine can only handle the sewing of the outer bag. The tying and sealing of the bag mouth of the inner layer bag still rely on manual operation. The manual bag-tying process takes a relatively long time in the total working hours of the packaging line, and due to operation differences, it is easy to cause packaging rework, resulting in low packaging production efficiency; and in a low-temperature environment of -30°C (such as a urea packaging workshop) or a dusty working condition, the manual operation efficiency is further reduced. For this kind of double-layer packaging bag, in the traditional process, the operations of gathering, folding, and tying the bag mouth of the inner layer bag are carried out by manual rope winding and tying, resulting in problems such as uneven tying force and discontinuous sealing lines; and the existing packaging equipment cannot perform the operations of gathering, folding, and then tying the bag for the bag mouth of the inner layer bag. In view of the above industry pain points, it is urgent to develop a new type of fully automatic packaging and sealing equipment to automatically complete the operations of gathering, folding, and packaging the bag mouth of the inner layer bag of the double-layer packaging bag. Summary of the Invention

The first servo motor 310 is in transmission cooperation with the bag holding support 32 to drive the bag holding support 32 to move on the first fixing frame 31. It should be noted that in some embodiments, the auxiliary clamping plate 36 can be replaced by a rod-shaped part.

[0058] With the above upper bag mechanism 3, at the initial working state, the double-layer packaging bag 9 for filling materials is conveyed onto the lifting plate 12. The bag holding support 32 is located at the position of the lifting plate 12, and the bag holding bottom plate 321 is located below the lifting plate 12. By the telescopic end of the first lifting cylinder 33 extending out, the bag mouth clamping plate 35 rises to both sides of the bag mouth of the double-layer packaging bag. The telescopic end of the clamping plate cylinder 34 extends out to drive the bag mouth clamping plates 35 on the two first side frames 322 to approach each other and clamp the bag mouth of the middle double-layer packaging bag 9, as Figure 4As shown in the figure; after the bag mouth is clamped, the telescopic end of the first lifting cylinder 33 contracts, so that the bag mouth clamping plate 35 clamps the bag mouth and descends synchronously. The telescopic end of the bag holding cylinder 37 extends to drive the bag holding clamping plate 38 to clamp the middle part of the double-layer packaging bag 9 filled with materials, realizing the clamping of the double-layer packaging bag 9. The bag holding limit block 39 is located on the front and back sides of the double-layer packaging bag 9 to limit the double-layer packaging bag 9, as Figure 5 shown in the figure; then the first servo motor 310 drives the bag holding bracket 32 to translate, driving the double-layer packaging bag 9 to move to the bag gathering mechanism 4 station for bag gathering.

[0059] Specifically, as Figures 6 - 13 shown in the figure, the bag gathering mechanism 4 includes a bag gathering frame 41 and a second servo motor 42 arranged at the upper end of the bag gathering frame 41. The output end of the second servo motor 42 is fixedly connected with a driving synchronous pulley 43. The lower end of the bag gathering frame 41 is rotatably connected with a driven synchronous pulley 44. A synchronous belt 45 is sleeved between the driving synchronous pulley 43 and the driven synchronous pulley 44. A first mounting frame 46 is arranged on the bag gathering frame 41 to slide up and down. The first mounting frame 46 is fixedly connected with one side of the synchronous belt 45; a first guide rail 47 parallel to the conveying direction of the double-layer packaging bag 9 is fixedly connected to the first mounting frame 46. A plurality of first sliders 48 are sleeved on the first guide rail 47. An adsorption clamping mechanism 8 is installed on the first sliders 48. The plurality of adsorption clamping mechanisms 8 are arranged in a staggered manner with the auxiliary clamping plate 36; one of the first sliders 48 is fixedly connected with the first mounting frame 46. The upper end of the first slider 48 is rotatably connected with a first connecting rod 49 and a second connecting rod 410. The first connecting rod 49 on each first slider 48 is hinged to the end of the second connecting rod 410 on the adjacent first slider 48. And the first connecting rods 49 between the adjacent first sliders 48 are parallel to each other, and the second connecting rods 410 are arranged parallel to each other. A gathering cylinder 411 is installed on the first mounting frame 46. The telescopic end of the gathering cylinder 411 is connected with one of the first sliders 48 sliding along the first guide rail 47 to drive the first sliders 48 to approach each other; the adsorption clamping mechanism 8 includes a pneumatic clamping component 81 fixed on the first slider 48. Two clamping ends driven by the pneumatic clamping component 81 are fixedly connected with a first connecting rod 82. The lower end of the first connecting rod 82 is fixedly connected with a claw hook 83 and a vacuum suction cup 84. The vacuum suction cup 84 is located above the claw hook 83. The claw hook 83 is provided with upwardly curved hook teeth 85, and the hook teeth 85 on the two first connecting rods 82 are arranged oppositely.

[0060] With the above-mentioned bag gathering mechanism 4, during operation, the double-layer packaging bag 9 is transferred to the working position of the bag gathering mechanism 4 through the bag loading mechanism 3. The adsorption and clamping mechanism 8 is located above the double-layer packaging bag 9. The second servo motor 42 drives the active synchronous pulley 43 to rotate, thereby driving the synchronous belt 45 to move. The movement of the synchronous belt 45 drives the first mounting bracket 46 to move downward, so that the adsorption and clamping mechanism 8 moves downward, making the double-layer packaging bag 9 located between the two first connecting rods 82. The pneumatic clamping assembly 81 acts to drive the two first connecting rods 82 to approach each other, so that the hook teeth 85 clamp the surface of the outer bag 91 below the flange 93 of the inner bag 92 bag mouth, and the hook teeth 85 and the auxiliary clamping plate 36 are arranged in a staggered manner so as not to interfere with each other. The end of the vacuum suction cup 84 fits on the flange 93 of the inner bag 92 bag mouth. The vacuum suction cup 84 is externally connected to a vacuum pump (not shown in the figure) through a vacuum valve. Opening the vacuum valve causes the vacuum suction cup 84 to suck the two side flanges 93 of the inner bag 92 bag mouth; then the telescopic end of the clamping plate cylinder 34 in the bag loading mechanism 3 contracts, driving the bag mouth clamping plate 35 to move away from the double-layer packaging bag 9 in a direction away from the double-layer packaging bag 9 to disengage from the bag mouth position of the double-layer packaging bag 9; the second servo motor 42 drives the active synchronous pulley 43 to rotate, thereby driving the synchronous belt 45 to move. The movement of the synchronous belt 45 drives the first mounting bracket 46 to move upward, thereby driving the adsorption and clamping mechanism 8 to move upward, so that the claw hooks 83 and the vacuum suction cup 84 move upward. The vacuum suction cup 84 adsorbs the flange 93 of the inner bag 92 to keep both sides of the flange 93 firm. The claw hooks 83 hook the flange 93 of the inner bag 92 and move upward. The upward movement of the claw hooks 83 stretches and straightens the flange 93 of the inner bag 92 upward. By the adsorption of the vacuum suction cup 84, the flange 93 is kept stable, so that the bag mouth remains flat when the flange 93 is straightened; at this time, the claw hooks 83 hook a small amount of the flange 93 of the inner bag 92 and keep it clamped. The telescopic end of the gathering cylinder 411 contracts to drive the first sliders 48 to approach each other. The adjacent first sliders 48 are connected by the first connecting rod 49 and the second connecting rod 410. The first connecting rod 49 and the second connecting rod 410 between the adjacent first sliders 48 form a parallelogram. When the gathering cylinder 411 drives the first sliders 48 to move, the multiple first sliders 48 move synchronously, thereby driving the multiple adsorption and clamping mechanisms 8 to approach each other, so that the inner bag 92 bag mouth approaches the middle in the width direction, making the inner bag 92 bag mouth gather together.

[0061] Specifically, a first connection seat 412 is fixedly connected to the middle of the first mounting bracket 46. Pressing bag cylinders 413 rotatably matched with the first connection seat 412 are mounted at both ends of the first connection seat 412. A pressing bag swing arm 414 is rotatably connected below the first mounting bracket 46. A first support shaft 415 is hingedly connected to the middle of the pressing bag swing arm 414. The telescopic end of the pressing bag cylinder 413 is rotatably connected to the first support shaft 415. A pressing bag rod 416 is fixedly connected to the lower end of the pressing bag swing arm 414. The telescopic ends of the pressing bag cylinders 413 extend to drive the pressing bag rods 416 on both sides to approach and close to each other. During operation, after a plurality of adsorption and clamping mechanisms 8 adsorb the bag mouth of the inner bag 92 and move it closer to the middle, the telescopic ends of the pressing bag cylinders 413 extend to close the pressing bag rods 416. The pressing bag rods 416 press on the inner bag 92 below the claw hooks 83, flattening the gathered folds of the inner bag 92. With the assistance of the pressing bag rods 416 for clamping, the bag mouth is flattened, facilitating gathering and making it convenient to tie the mouth of the inner bag 92.

An arc groove 69 is arranged in the middle of the nylon claw 68, and the arc grooves 69 on the nylon claws 68 on both sides of the first driving cylinder 65 are arranged oppositely. When the telescopic end of the first driving cylinder 65 extends, it drives the swing rod 67 to swing, causing the nylon claws 68 to close towards the middle. During operation, after the double bag clamping mechanism 5 gathers the mouth of the inner bag 92 into a bundle, the conveyor belt 2 and the translation module 13 move synchronously to convey the double-layer packaging bag 9 to the lower part of the rotary bag clamping mechanism 6. The telescopic end of the first driving cylinder 65 extends to drive the swing rod 67 to swing. The swing rod 67 swings inward, causing the nylon claws 68 to clamp on the gathered bundle 94 between the first bag clamping plate 59 and the second bag clamping plate 513. The first stepping motor 62 drives the second connecting seat 64 to rotate, and then drives the nylon claws 68 to rotate, rotating the gathered bundle 94 at the mouth of the inner bag 92 for 1-2 circles, making the gathered bundle 94 at the mouth of the inner bag 92 more concentrated and keep an upright state.

[0064] Specifically, as Figures 17 - 25As shown in the figure, the bag mouth folding device 7 includes a connecting bottom plate 71 installed on the moving part of the translation module 13. A translation bottom plate 72 is slidably connected to the connecting bottom plate 71 through a slide rail. A translation cylinder 73 is installed on the connecting bottom plate 71.

Both the first clamping jaw 79 and the second clamping jaw 710 are hinged to the clamping jaw seat 76. Two clamping jaw cylinders 711 are installed on the clamping jaw seat 76. The telescopic ends of the two clamping jaw cylinders 711 are respectively hinged to the sides of the first clamping jaw 79 and the second clamping jaw 710. The telescopic end of the clamping jaw cylinder 711 contracts to drive the first clamping jaw 79 or the second clamping jaw 710 to open away from the fixed rod 78. A folding shaft 712 is slidably connected to the mounting seat 74. The folding shaft 712 passes through the rotating seat 75 along the rotation center of the rotating seat 75. A second driving cylinder 713 is installed on the translation bottom plate 72. The telescopic end of the second driving cylinder 713 is fixedly connected to one end of the folding shaft 712 away from the clamping jaw seat 76.

[0065] Adopting the above bag mouth folding device 7 solution, the initial state during operation is as follows: the telescopic end of the clamping jaw cylinder 711 contracts to drive both the first clamping jaw 79 and the second clamping jaw 710 to open away from the fixed rod 78. The telescopic end of the translation cylinder 73 extends to drive the translation bottom plate 72 to push towards the double-layer packaging bag 9.

[0067] Adopting the above-mentioned bag tying mechanism 11 solution, the conveyor belt 2 and the translation module 13 convey the double-layer packaging bag 9 and the bag mouth folding device 7 to the corresponding position of the bag tying mechanism 11. The third lifting cylinder 112 drives the gripper bottom plate 113 to move downward, and the third driving cylinder 115 drives the clamping clamp 114 to close. The clamping clamp 114 clamps the upper end of the folded and gathered bundle 94 formed by the bag mouth of the inner bag 92. Then, the bag mouth folding device 7 resets. One end of the binding rope is clamped on the rope clamping clamp 1110. The third servo motor 118 drives the rotating ring 117 to rotate, thereby driving the rope clamping clamp 1110 to rotate, and winding the binding rope around the bag mouth gathered bundle 94 of the inner bag 92. During the winding process of the binding rope, the fourth driving cylinder 1113 drives the swing plate 1112 to swing downward, so that the binding rope is wound into the rope clamping rod 1114 and the rope clamping hook 1115, and the binding rope is knotted after continuous winding. Then, the sixth driving cylinder 1117 drives the starting scissors to cut the binding rope, completing the binding of the binding rope at the bag mouth of the inner bag 92. The third lifting cylinder 112 continues to drive the gripper bottom plate 113 to move downward, and the clamping clamp 114 presses the gathered bundle 94 of the inner bag 92 downward into the outer packaging bag. Then, the bag tying mechanism 11 resets, and the conveyor belt 2 conveys the double-layer packaging bag 9 to the next station.

[0068] Specifically, it further includes a bag supporting mechanism 17 installed on the frame 1. The bag supporting mechanism 17 is located on the side of the bag tying mechanism 11 away from the double-clamping inner bag mechanism 5, as Figure 28 shown. The bag supporting mechanism 17 includes a top plate 171 fixed on the frame 1. A fourth lifting cylinder 172 is installed on the top plate 171. The telescopic end of the fourth lifting cylinder 172 is fixedly installed with a second slider 173. A guide rod 174 is fixedly connected to the top plate 171. The second slider 173 slides up and down in cooperation with the guide rod 174. A first synchronous pulley 175 and a second synchronous pulley 176 are rotatably connected to the second slider 173. A first synchronous belt 177 is sleeved on the first synchronous pulley 175 and the second synchronous pulley 176 to form a synchronous belt 45 drive. The upper and lower sides of the first synchronous belt 177 are respectively fixedly connected with a third slider 178 and a fourth slider 179. It should be noted that the third slider 178 and the fourth slider 179 are slidably matched with the second slider 173 through a slide rail.

A bag supporting cylinder 1712 is installed on the second slider 173. The telescopic end of the bag supporting cylinder 1712 is fixedly connected to the third slider 178.

[0069] Adopting the above-mentioned bag-supporting mechanism 7 solution, after the mouth of the inner bag 92 of the double-layer packaging bag 9 is tied and pressed into the outer bag 91, the double-layer packaging bag 9 filled with materials is conveyed to the lower part of the bag-supporting mechanism 17 through the conveyor belt 2. The fourth lifting cylinder 172 drives the second slider 173 to move downward. At this time, when the bag-supporting cylinder 1712 contracts, the first support rod 1710 and the second support rod 1711 move closer to each other. During the downward movement of the second slider 173, the first support rod 1710 and the second support rod 1711 extend from the mouth of the outer bag 91 into the outer bag 91. The telescopic end of the bag-supporting cylinder 1712 extends, driving the first support rod 1710 and the second support rod 1711 to move away from each other, thereby stretching the mouth of the outer bag 91 into a straight line state, which is convenient for sealing.

[0070] Specifically, as Figures 29 - 31 shown, an upper bag-holding device 18 and a belt guiding device 19 are further provided on the frame 1.

The two groups of belt pulley sets 191 are arranged on the guide rail and are driven by an opening and closing cylinder to move closer to clamp the mouth of the outer bag 91. The synchronous pulley is driven by a motor to rotate. Through the above structure, the electric cylinder driving mechanism 181 drives the upper clamping plate 182 and the lower clamping plate 183 to move to the position of the bag-supporting mechanism 17. The upper clamping plate 182 is driven by a cylinder to move closer to clamp the mouth of the packaging bag, and the lower clamping plate 183 is driven by a cylinder to clamp the body of the packaging bag. Driven by the electric cylinder driving mechanism 181, the double-layer packaging bag 9 is dragged onto the sewing conveyor 15. After the mouth of the outer bag 91 enters the belt guiding device 19, the two groups of belt pulley sets 191 move closer to clamp the mouth of the outer bag 91 and are driven to move by the second synchronous belt. The belt guiding device 19, the sewing conveyor 15, and the sewing machine 14 work with matching speeds, so that the double-layer packaging bag 9 smoothly transitions into the sewing machine 14 to sew the mouth of the outer bag 91, completing the sealing action of the entire packaging bag.

[0071] Specifically, it further includes a sewing machine 14. The sewing machine 14 is located on the side of the belt guiding device 19 away from the bag tying mechanism 11. The sewing machine 14 is used to sew the opening of the outer bag 91 of the double-layer packaging bag 9. A sewing conveyor 15 is arranged below the sewing machine 14. A roller 16 is arranged at the docking gap between the sewing conveyor 15 and the conveyor belt 2. The double-layer packaging bag 9 is conveyed to the sewing conveyor 15 through the conveyor belt 2 and is transitioned through the roller 16 during the conveyance to ensure that the double-layer packaging bag 9 is conveyed onto the sewing conveyor 15. The double-layer packaging bag 9 is conveyed to the sewing machine 14 by the sewing conveyor 15 to sew the outer bag 91. Specifically, railings 21 are arranged on both sides of the conveyor belt 2 to support the sides of the double-layer packaging bag through the railings 21, thereby improving the conveyance stability.

[0072] Working principle: the bag opening of the inner bag 92 of the double-layer packaging bag 9 is folded outward to the outside of the outer bag 91 to form a bag opening flange 93. The double-layer packaging bag 9 filled with materials is transported to the lifting plate 12 through the previous process. The bag holding bracket 32 in the bag loading mechanism 3 moves to the corresponding position of the lifting plate 12. The bag holding bottom plate 321 is located below the lifting plate 12 and is extended through the telescopic end of the first lifting cylinder 33. The bag opening clamping plate 35 rises to both sides of the bag opening of the double-layer packaging bag.
