Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a servo bag-picking and placing mechanism for a bagging machine. Background Technology

[0002] As society develops, people's living standards and quality of life are gradually improving. Packaging technology, along with people's demand for efficient product packaging, has begun to move towards automation and mechanization. Nowadays, in order to cope with the large number of products that need packaging, various packaging equipment has been invented, and many packaging equipment use plastic packaging bags to package products.

[0003] Plastic packaging bags are typically placed in a bag-retrieving box during use. The bag-retrieving mechanism is used to individually remove and unfold the bags before moving them to the bag-filling mechanism to flatten them, making it easier for the bag-filling mechanism to package the products.

[0004] By using bag-picking and-placing mechanisms, people have achieved mechanical automation of bag picking and placing, saving labor costs and using machinery to complete some tedious and repetitive tasks, thereby improving the efficiency of bag picking and placing.

[0005] Existing bag-picking and placing mechanisms typically use cylinders and suction cups to grab and lift the packaging bags, then use linear modules for linear transport. Finally, upon reaching the designated location, cylinders and suction cups lower the packaging bags for placement. The entire process is very fast and efficient. However, these existing bag-picking and placing mechanisms still have some shortcomings. They require high precision in the height at which the packaging bags are grabbed and placed. If the height is too low, the bags may not be grabbed, while if the height is too high, the bags may be crushed and damaged. Adjusting the height of the equipment is a delicate and tedious task, and the equipment is prone to height deviations after prolonged operation, requiring frequent fine-tuning by staff, which is quite troublesome. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a servo bag-picking and placing mechanism for a bagging machine to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a servo bag-picking and placing mechanism for a bagging machine, comprising a support base, a synchronous belt linear module on the top of the support base, multiple feet fixedly mounted on the top of the support base, the synchronous belt linear module mounted inside the feet, a belt slider slidably mounted on the synchronous belt linear module, a mounting base fixedly mounted on the top of the belt slider, a sliding component mounted on one side of the mounting base, a vacuum adsorption component mounted below the sliding component, a connecting component between the sliding component and the vacuum adsorption component, the vacuum adsorption component including a suction tube mounting plate and a buffer metal vacuum suction cup, and two suction tube mounting plates connected and mounted below the connecting component. The suction cup mounting plate has two symmetrically arranged strip-shaped limiting mounting holes on one side. Two buffer metal vacuum suction cups are installed on the inner sides of both ends of the strip-shaped limiting mounting holes. Each buffer metal vacuum suction cup includes a vacuum suction rod, which is slidably installed at one end of the strip-shaped limiting mounting hole. A limiting mechanism is provided on the outer side of the vacuum suction rod. An air pump connection port is connected to the top of the vacuum suction rod, and a vacuum suction cup is connected to the bottom of the vacuum suction rod. A sliding limiting block is slidably installed on the outer side of the vacuum suction rod, and the sliding limiting block is slidably installed below the suction cup mounting plate and in contact with the bottom of the suction cup mounting plate. A spring is provided on the outer side of the vacuum suction rod, and the spring is connected and installed between the vacuum suction cup and the sliding limiting block.

[0008] By adopting the above technical solution, a synchronous belt linear module is used to drive the belt slider and subsequent connected components to perform linear motion. A mounting base facilitates the installation of the sliding assembly and connects it to the synchronous belt linear module. The sliding assembly drives the vacuum adsorption assembly to slide up and down for adsorption and transportation. The vacuum adsorption assembly adsorbs and grips the packaging bag, and transports the bag in cooperation with the synchronous belt linear module and the sliding assembly. When the vacuum adsorption assembly reaches the target position, it stops adsorbing the bag and places it in the designated location. A connecting assembly connects and installs the vacuum adsorption assembly onto the sliding assembly. A suction tube mounting plate and a strip-shaped limiting mounting hole are used to install a buffer metal vacuum suction cup. The buffer metal vacuum suction cup provides a cushioning effect when the vacuum adsorption assembly adsorbs the packaging bag, preventing damage from squeezing during adsorption and reducing the need for precision in the adsorption and placement height of the packaging bag. This design eliminates the need for frequent precision adjustments by staff, reducing hassle. A limiting mechanism restricts the vacuum suction rod, ensuring it stays within the strip-shaped mounting hole. An air pump connection creates a vacuum inside the buffer metal vacuum suction cup, allowing for the suction and gripping of the packaging bag. The system utilizes the vacuum suction rod, vacuum suction cup, sliding limit block, and spring. As the sliding assembly lowers the vacuum suction assembly to grip the bag, the vacuum suction cup gradually descends until it contacts the bag. Once in contact, the suction tube mounting plate compresses the spring, causing the sliding limit block to slide downwards a short distance on the outside of the vacuum suction rod. The spring force strengthens the connection between the vacuum suction cup and the bag, resulting in a more secure grip. Furthermore, the spring's elasticity reduces pressure on the bag, preventing damage and minimizing the need for high precision in bag gripping and placement height.

[0009] The present invention is further configured such that the limiting mechanism is a limiting block, and the limiting block is fixedly installed on the outside of the vacuum suction rod.

[0010] By adopting the above technical solution, a limiting block is used to limit the vacuum suction rod, so that the vacuum suction rod can be limited to the inside of the strip-shaped limiting mounting hole.

[0011] The present invention is further configured such that the synchronous belt linear module includes a belt slide rail, the belt slide rail is fixedly installed on the inner side of the foot base, one end of the belt slide rail is equipped with an active synchronous pulley, the other end of the belt slide rail is equipped with a driven synchronous pulley, a circular motor base is installed on one side of the active synchronous pulley, and a servo motor is installed on one side of the circular motor base.

[0012] By adopting the above technical solution, a circular motor mount can be used to install the servo motor. The servo motor provides power to drive the belt to move synchronously between the belt slide, the active synchronous pulley, and the driven synchronous pulley, thereby driving the belt slider to move linearly.

[0013] The present invention is further configured such that the sliding assembly includes a guide rail fixing plate, the guide rail fixing plate is fixedly installed on one side of the mounting base, two symmetrical guide rails are fixedly installed on one side of the guide rail fixing plate, guide rail sliders are slidably provided on the guide rails, a cylinder mounting base is fixedly installed on one side of the guide rail fixing plate, a cylinder is fixedly installed on one side of the cylinder mounting base, a cylinder slide rod is slidably provided on the inner side of the cylinder, a circular hole is provided through one side of the cylinder mounting base to facilitate the sliding of the cylinder slide rod, a cylinder push plate is fixedly installed on the top of the cylinder, a slider upper seat is fixedly installed on one side of the cylinder push plate, and one side of the slider upper seat is fixedly connected to the two guide rail sliders.

[0014] By adopting the above technical solution, a guide rail fixing plate is used to fix the guide rail and the cylinder mounting seat. A cylinder mounting seat is used to facilitate the installation of the cylinder. A cylinder and a cylinder slide rod are used so that the cylinder can drive the cylinder slide rod to slide up and down during operation. A cylinder push plate is used to facilitate the installation of the slider upper seat. When the cylinder slide rod slides up and down, it can simultaneously drive the slider upper seat to move up and down. A guide rail and a guide rail slider are used to limit and guide the up and down movement of the slider upper seat, preventing the slider upper seat from shaking and becoming unstable during movement. By using a slider upper seat, when the cylinder slide rod slides up and down, the slider upper seat can drive the connecting component and the vacuum adsorption component to move up and down synchronously.

[0015] The present invention is further configured such that the connecting component comprises multiple strip-shaped connecting plates, and the multiple strip-shaped connecting plates are fixedly installed on one side of the upper seat of the slider.

[0016] By adopting the above technical solution, a strip connecting plate is used to connect the vacuum adsorption component and the sliding component.

[0017] The present invention is further configured such that an air pump is connected to the air pump connection port via an air pipe.

[0018] By adopting the above technical solution, and by incorporating an air pump and air pipe, a vacuum can be formed inside the buffer metal vacuum suction cup, thereby enabling it to adsorb and grasp the packaging bag.

[0019] The present invention is further configured such that the vacuum suction cup is made of silicone rubber with a certain degree of rigidity and flexibility.

[0020] By adopting the above technical solution, the vacuum suction cup can also provide some cushioning effect when it is sucking up the packaging bag.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model incorporates a buffer metal vacuum suction cup, which provides a cushioning effect when the vacuum adsorption component adsorbs packaging bags. A spring is installed on the outside of the vacuum suction rod, causing the suction tube mounting plate to drive the sliding limit block to compress the spring as the vacuum suction cup adsorbs the packaging bag, thus providing a cushioning effect. This reduces the squeezing effect on the packaging bag, preventing damage. It also reduces the precision requirements for the height of the packaging bag placement, decreases the frequency of equipment adjustments by operators, and avoids considerable inconvenience.

[0023] 2. This utility model uses a guide rail and a guide rail slider to limit and guide the up and down movement of the upper slider seat, thus preventing the upper slider seat from shaking and becoming unstable during movement. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] A servo bag-picking and dispensing mechanism for a bagging machine, such as Figure 1 - Figure 5As shown, the system includes a support base 1, with a synchronous belt linear module 2 mounted on its top. Multiple feet 11 are fixedly mounted on the top of the support base 1. The synchronous belt linear module 2 is installed inside the feet 11. A belt slider 26 is slidably mounted on the synchronous belt linear module 2. The synchronous belt linear module 2 enables the belt slider 26 and subsequent connected components to move linearly. A mounting base 3 is fixedly mounted on the top of the belt slider 26. A sliding assembly 4 is mounted on one side of the mounting base 3. A vacuum adsorption assembly 5 is mounted below the sliding assembly 4. The mounting base 3 facilitates the installation of the sliding assembly 4 and connects it to the synchronous belt linear module 2. Component 4 can drive the vacuum adsorption component 5 to slide up and down for adsorption and transportation. The vacuum adsorption component 5 can adsorb and grasp the packaging bag, and transport the packaging bag with the cooperation of the synchronous belt linear module 2 and the sliding component 4. When the vacuum adsorption component 5 reaches the target position, it stops adsorbing the packaging bag and places it in the designated position. A connecting component is provided between the sliding component 4 and the vacuum adsorption component 5, which connects and installs the vacuum adsorption component 5 onto the sliding component 4. The vacuum adsorption component 5 includes a suction tube mounting plate 51 and a buffer metal vacuum suction cup. Two suction tube mounting plates 51 are connected and installed below the connecting component. Two suction tube mounting plates 51 are symmetrically opened on one side. A strip-shaped limiting mounting hole 52 is provided, and two buffer metal vacuum suction cups are installed on the inner sides of both ends of the strip-shaped limiting mounting hole 52. The buffer metal vacuum suction cups can be installed through the suction tube mounting plate 51 and the strip-shaped limiting mounting hole 52. The buffer metal vacuum suction cups provide a buffering effect when the vacuum adsorption component 5 adsorbs the packaging bag, preventing damage to the packaging bag during adsorption and reducing the precision requirements for the height of the packaging bag suction and placement. This reduces the need for frequent precision adjustments by the operator, saving considerable trouble. The buffer metal vacuum suction cup includes a vacuum suction rod 53, which is slidably mounted on one end of the strip-shaped limiting mounting hole 52. A limiting device is provided on the outer side of the vacuum suction rod 53. The mechanism includes a limiting block 54, which is fixedly installed on the outside of the vacuum suction rod 53. The top of the vacuum suction rod 53 is connected to an air pump connection port 55, which is connected to an air pump via an air pipe. The bottom of the vacuum suction rod 53 is connected to a vacuum suction cup 56, which is made of silicone rubber with a certain degree of rigidity and flexibility, allowing it to provide some cushioning when suctioning the packaging bag. A sliding limiting block 57 is slidably installed on the outside of the vacuum suction rod 53, sliding below the suction tube mounting plate 51 and contacting the bottom of the suction tube mounting plate 51. A spring 58 is provided on the outside of the vacuum suction rod 53.The spring 58 is connected and installed between the vacuum suction cup 56 and the sliding limit block 57. The limit block 54 limits the vacuum suction rod 53, allowing it to be positioned inside the strip-shaped limit mounting hole 52. The air pump connection port 55 allows a vacuum to be created inside the buffer metal vacuum suction cup under the action of the air pump, enabling the suction and gripping of the packaging bag. With the vacuum suction rod 53, vacuum suction cup 56, sliding limit block 57, and spring 58, the sliding assembly 4 drives the vacuum suction assembly 5 to descend and suction the packaging bag. The vacuum suction cup 56 gradually descends until it contacts the packaging bag. Once in contact, the suction tube mounting plate 51 causes the sliding limit block 57 to compress the spring 58, which slides downwards on the outside of the vacuum suction rod 53. At this point, the vacuum suction cup 56 is strengthened by the elastic force of the spring 58, resulting in a more stable grip on the packaging bag. Furthermore, due to the buffering effect of the spring 58, the pressure on the packaging bag is reduced, preventing damage from compression. This also reduces the precision requirements for the gripping and placement height of the packaging bag.

[0033] Please see Figure 1 The synchronous belt linear module 2 includes a belt slide rail 21, which is fixedly installed on the inner side of the foot 11. One end of the belt slide rail 21 is equipped with a driving synchronous pulley 22, and the other end of the belt slide rail 21 is equipped with a driven synchronous pulley 23. A circular motor mount 24 is installed on one side of the driving synchronous pulley 22, and a servo motor 25 is installed on one side of the circular motor mount 24. The servo motor 25 can be installed by the circular motor mount 24. With the belt slide rail 21, driving synchronous pulley 22, driven synchronous pulley 23 and servo motor 25, the servo motor 25 provides power to drive the belt to move synchronously between the belt slide rail 21, driving synchronous pulley 22 and driven synchronous pulley 23, thereby driving the belt slider 26 to move linearly.

[0034] Please see Figure 2 and Figure 3The sliding assembly 4 includes a guide rail fixing plate 41, which is fixedly installed on one side of the mounting base 3. Two symmetrical guide rails 42 are fixedly installed on one side of the guide rail fixing plate 41. Guide rail sliders 43 are slidably mounted on the guide rails 42. A cylinder mounting base 44 is fixedly installed on one side of the guide rail fixing plate 41. A cylinder 45 is fixedly installed on one side of the cylinder mounting base 44. A cylinder slide rod 46 is slidably mounted on the inner side of the cylinder 45. A circular hole is provided through one side of the cylinder mounting base 44 to facilitate the sliding of the cylinder slide rod 46. A cylinder push plate 47 is fixedly installed on the top of the cylinder 45. A slider upper seat 48 is fixedly installed on one side of the cylinder push plate 47. One side of the slider upper seat 48 is fixedly connected to the two guide rail sliders 43. Plate 41 fixes the guide rail 42 and cylinder mounting base 44. The cylinder mounting base 44 facilitates the installation of cylinder 45. The cylinder 45 and cylinder slide rod 46 allow cylinder 45 to drive cylinder slide rod 46 to slide up and down during operation. The cylinder push plate 47 facilitates the installation of slider upper seat 48 and simultaneously drives slider upper seat 48 to move up and down when cylinder slide rod 46 slides up and down. The guide rail 42 and guide rail slider 43 limit and guide the up and down movement of slider upper seat 48 to prevent wobbling and instability during movement. The slider upper seat 48 allows the connecting component and vacuum adsorption component 5 to move up and down synchronously when cylinder slide rod 46 slides up and down.

[0035] Please see Figure 4 The connecting component consists of multiple strip connecting plates 6, which are fixedly installed on one side of the slider seat 48. The vacuum adsorption component 5 and the sliding component 4 are connected by the strip connecting plates 6.

[0036] The working principle of this utility model is as follows: When using this device, first place the bag-collecting box at a certain height, then connect the power supply to start working. At this time, the cylinder 45 drives the cylinder slide rod 46 to retract and slide downwards. The cylinder slide rod 46 drives the cylinder push plate 47 and the upper slider seat 48 to move downwards synchronously. Under the guidance and limiting action of the guide rail 42 and the guide rail slider 43, the upper slider seat 48 moves smoothly and stably. The upper slider seat 48 drives the strip connecting plate and the vacuum adsorption component 5 to move downwards, and due to the vacuum adsorption effect generated by the air pump, it begins to suck up the packaging bag. When the vacuum suction cup 56 contacts and adsorbs the packaging bag, the suction tube mounting plate 51 will drive the sliding limit block 57 to compress the spring 58 and slide downwards on the outside of the vacuum suction rod 53. At this time, the vacuum suction cup 56 will be strengthened by the elastic force of the spring 58 to enhance the connection effect with the packaging bag, thereby making the vacuum suction cup 56 grip the packaging bag more firmly, and by Due to the buffering effect of the spring 58, the pressure on the packaging bag is small and it will not be squeezed and damaged. Under the control of the cylinder 45, the suction tube mounting plate 51 and the sliding limit block 57 begin to rise after sliding down a certain distance. At this time, the packaging bag moves upward due to the suction effect of the vacuum suction cup 56. After reaching the limit height, the synchronous belt linear module 2 starts to work. At this time, the belt slider 26 is driven by the synchronous belt linear module 2 to drive the mounting base 3, sliding component 4, connecting component, vacuum suction component 5 and packaging bag to perform linear transportation. After reaching the designated position, the cylinder 45 drives the cylinder slide rod 46 to retract and slide downward to transport the vacuum suction cup 56 and packaging bag downward. After reaching the set position, the air pump releases the vacuum suction effect, the packaging bag falls, and then the vacuum suction cup 56 returns to the original position through the effect of the sliding component 4 and the synchronous belt linear module 2 and repeats the suction and transportation of the packaging bag.
