Description

Technical Field

[0001] This invention relates to the field of bagging equipment technology, specifically to an environmentally friendly bagging device for cardboard boxes and its control method. Background Technology

[0002] In the production process of paper beverage packaging boxes, the finished packaging boxes need to be packed into cartons in batches. In order to ensure hygiene, a film bag needs to be placed inside the carton to put the packaging boxes inside the film bag.

[0003] Currently, manual bagging is the most common method. However, manual bagging makes it difficult to maintain a consistent pressure when spreading the bag, easily leading to tearing due to uneven force, increasing the risk of bag waste, and hindering energy conservation and environmental protection. Furthermore, manual bagging increases labor costs and reduces bagging efficiency.

[0004] Therefore, how to reduce the risk of membrane bag scrapping, reduce labor costs, and improve bagging efficiency are the technical problems that need to be solved. Summary of the Invention

[0005] This invention addresses the aforementioned shortcomings of existing technologies by providing an environmentally friendly cardboard bagging device and its control method. This invention can reduce the risk of waste of film bags, reduce labor costs, and improve bagging efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An environmentally friendly cardboard box bagging device includes a frame, a film bag conveying mechanism on the lower left side of the frame that conveys film bags in a front-to-back direction, a cardboard box conveying mechanism on the lower right side of the frame that conveys cardboard boxes in a front-to-back direction, a bag unfolding mechanism in the lower middle of the frame, a picking mechanism above the film bag conveying mechanism for picking up film bags conveyed by the film bag conveying mechanism, a moving mechanism above the picking mechanism located on the upper part of the frame that drives the picking mechanism to move in a left-to-right direction above the bag unfolding mechanism, a swing arm and a rotating mechanism for driving the swing arm to rotate on the upper right side of the frame, and a transfer mechanism at the end of the swing arm away from the frame.

[0008] Furthermore, the bag-spreading mechanism includes a bag-spreading suction cup and a bag-spreading air supply device, the bag-spreading air supply device being used to draw or supply air into the bag-spreading suction cup;

[0009] The pickup mechanism includes a pickup lifting rod, a pickup suction cup, and a pickup air supply device. The upper part of the pickup lifting rod is connected to the moving mechanism, and the lower part of the pickup lifting rod is provided with a pickup suction cup. The pickup air supply device is used to draw or supply air into the pickup suction cup.

[0010] The transfer mechanism includes an adsorption cylinder, a transfer lifting rod, and a transfer air supply device. The adsorption cylinder includes a first cylinder and a second cylinder that are connected to each other. The lower surface of the first cylinder is provided with a number of first through holes, which are inclined outward. The side of the second cylinder is provided with a number of second through holes. One end of the transfer lifting rod is connected to the swing arm, and the other end of the transfer lifting rod is connected to the first cylinder. The transfer air supply device is used to draw or deliver air into the adsorption cylinder.

[0011] Furthermore, the rotating mechanism includes a rotating motor, which is located on the upper part of the frame, and the output shaft of the rotating motor is connected to the swing arm;

[0012] The moving mechanism includes a moving base, a moving motor, a gear, and a rack. The moving base is slidably connected to the upper part of the frame in the left-right direction. The moving base is equipped with a moving motor, and the output shaft of the moving motor is equipped with a gear. The upper part of the frame is equipped with a rack extending in the left-right direction, and the rack meshes with the gear. The moving base is connected to the upper part of the picking lifting rod.

[0013] Furthermore, the bag-displaying mechanism also includes a bag-displaying lifting rod, the upper end of which is provided with the bag-displaying suction cup.

[0014] Furthermore, both the film bag conveying mechanism and the carton conveying mechanism are belt conveyors.

[0015] Furthermore, the end of the film bag conveying mechanism is provided with a film bag feeding mechanism, which includes a storage box containing stacked film bags. The bottom of the storage box has a window, and the side wall of the storage box has a discharge port that communicates with the window. The bottom layer of film bags contacts the film bag conveying mechanism through the window.

[0016] Furthermore, the storage bag box is provided with a limiting plate on the side where the discharge port is located. The limiting plate has an elongated hole, and a screw is installed in the elongated hole. The screw is connected to the side of the storage bag box, and a nut is connected to the screw. The limiting plate is sandwiched between the side wall of the storage bag box and the nut.

[0017] Furthermore, it also includes a control module and a detection module. The detection module, the film bag conveying mechanism, the carton conveying mechanism, the pickup lifting rod, the transfer lifting rod, the moving mechanism, the rotating mechanism, the pickup air supply device, the bag unfolding air supply device, and the transfer air supply device are all electrically connected to the control module.

[0018] A control method for an environmentally friendly cardboard box bagging device, based on such a device, includes the following steps:

[0019] S1. When the control module receives a signal that the film bag is being transmitted to the area below the pickup suction cup, the control module not only controls the film bag transmission mechanism to stop, but also controls the output end of the pickup lifting rod to extend downward, thereby reducing the height of the pickup suction cup.

[0020] S2. When the control module receives the signal that the pickup suction cup has descended to the position, the control module not only controls the output end of the pickup lifting rod to stop extending, but also controls the pickup air supply device to extract the air in the pickup suction cup, so that the pickup suction cup picks up the film bag.

[0021] S3. When the control module receives the signal to pick up the suction cup to adsorb the film bag, the control module not only controls the air supply device to maintain the state of picking up the suction cup to adsorb the film bag, but also controls the moving mechanism to move together with the picking up lifting rod, the picking up suction cup and the film bag to the top of the spreading suction cup.

[0022] S4. When the control module receives a signal that the pick-up suction cup has moved above the spreading bag suction cup, the control module not only controls the moving mechanism to stop, but also controls the spreading bag air supply device to extract the air in the spreading bag suction cup, so that the spreading bag suction cup adsorbs the lower surface of the film bag.

[0023] S5. When the control module receives the signal that the bag spreading suction cup is adsorbing the film bag, the control module not only controls the bag spreading air supply equipment to keep the bag spreading suction cup adsorbing the film bag, the module control also controls the output end of the pickup lifting rod to retract, driving the pickup suction cup to rise while adsorbing the upper surface of the film bag, so that the distance between the bag spreading suction cup and the pickup suction cup increases, so that the bag opening can be opened.

[0024] S6. When the control module receives a signal that the bag opening of the film bag is open, the control module not only controls the output end of the pickup lifting rod to stop retracting, but also controls the rotating mechanism to drive the swing arm to rotate, so that the swing arm rotates from the horizontal state downward to the vertical state. When the swing arm rotates to the vertical state, the adsorption tube on the swing arm gradually inserts into the inside of the film bag.

[0025] S7. When the control module receives the swing arm turning to the vertical state, the control module not only controls the rotation mechanism to stop, but also controls the pickup suction cup and the bag spreading suction cup to cancel the adsorption state of the film bag. Then the control module controls the transfer air supply device to extract the air in the adsorption cylinder, so that the adsorption cylinder adsorbs the film bag.

[0026] S8. When the control module receives the signal that the adsorption cylinder adsorbs the film bag, the control module not only controls the rotation mechanism to drive the swing arm to rotate in the opposite direction, so that the swing arm is reset from the vertical state to the horizontal state, so that the adsorption cylinder carrying the film bag is above the carton conveying mechanism, the control module also controls the moving mechanism to move in the opposite direction, driving the picking lifting rod and picking suction cup to reset above the film bag conveying mechanism.

[0027] S9. When the control module receives a signal that the swing arm has been reset to the horizontal state, the control module controls the rotation mechanism to stop.

[0028] S10. When the control module receives a signal that the moving mechanism carrying the pickup lifting rod and pickup adsorption plate has been reset above the film bag transfer mechanism, the control module not only controls the moving mechanism to stop, but also controls the film bag transfer mechanism to continue running.

[0029] S11. When the control module receives a signal that the carton has been transferred to the bottom of the adsorption cylinder, the control module not only controls the carton transfer mechanism to stop, but also controls the output end of the transfer lifting rod to extend downward, so that the adsorption cylinder carries the film bag into the carton.

[0030] S12. When the control module receives the signal that the adsorption cylinder has entered the carton, the control module controls the transfer air supply device to fill the adsorption cylinder with air. The air blown out from the first through hole blows the bag opening of the film bag towards the carton opening, realizing the bag opening of the film bag is turned upside down. The air blown out from the second through hole blows the film bag towards the inner wall of the carton, completing the bagging.

[0031] S13. When the control module receives the signal that the carton has been bagged, the control module not only controls the transfer air supply equipment to shut down, but also controls the output end of the transfer lifting rod to retract and reset, so that the adsorption cylinder rises and resets.

[0032] S14. When the control module receives the signal for the suction cylinder to rise and reset, the control module not only controls the transfer lifting rod to stop, but also controls the carton conveying mechanism to continue running.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. In the carton environmental protection bagging device of the present invention, a mechanized method is used to open the film bag and bag the carton, with uniform force. This avoids tearing the film bag due to uneven force when opening the film bag or bagging the carton manually, thereby reducing the waste of film bags and saving resources and protecting the environment.

[0035] 2. In the carton environmental protection bagging device of the present invention, the picking suction cup, the bag spreading suction cup, and the adsorption cylinder all contact the film bag by adsorption, without any sharp structure contacting the film bag, which further reduces the risk of film bag damage and further facilitates saving and environmental protection.

[0036] 3. In the paper box environmental protection bagging device of the present invention, because mechanized bagging is realized, not only can bagging efficiency be improved, but labor costs can also be saved.

[0037] 4. The paper box environmental protection bagging device of the present invention picks up the film bags one by one, so this device is suitable for bagging individual film bags, but not suitable for rolls of film bags.

[0038] 5. In the adsorption cylinder of this invention, air blown from the first through-hole blows the opening of the film bag toward the opening of the carton, enabling the opening of the film bag to be turned upside down without manual turning; air blown from the second through-hole blows the film bag toward the inner wall of the carton, expanding the film bag to its maximum size without manual expansion. The expanded and turned-up film bag is more convenient for packaging and boxing.

[0039] 6. In a carton environmental protection bagging device of the present invention, the setting of the bag spreading lifting rod can adjust the height of the bag spreading suction cup so as to be flush with the height of the film bag conveying mechanism of different heights. When the moving mechanism drives the picking suction cup to move above the bag spreading suction cup, the distance between the bag spreading suction cup and the picking suction cup can be reduced, so that the film bag adsorbed on the picking suction cup is closer to the bag spreading suction cup, so that the bag spreading suction cup can easily adsorb the lower surface of the film bag, thereby improving the flexibility of use.

[0040] 7. In the carton environmental protection bagging device of the present invention, the setting of the film bag feeding mechanism can realize the mechanical feeding of film bags, eliminating the need for manual feeding of film bags, which helps to further reduce the labor intensity of workers.

Detailed Implementation

[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] Example 1:

[0070] like Figures 1-9 An environmentally friendly cardboard box bagging device includes a frame 1, a film bag conveying mechanism 2, a cardboard box conveying mechanism 3, a bag unfolding mechanism 4, a picking mechanism 5, a moving mechanism 6, a swing arm 7, a rotating mechanism, and a transfer mechanism 9.

[0071] like Figure 1 As shown, the film bag conveying mechanism 2 is located on the lower left side of the frame 1. The film bag conveying mechanism 2 is used to convey film bags 10 in the front-to-back direction. In this embodiment, the film bag conveying mechanism 2 can be a belt conveyor, which is an existing and mature piece of equipment. The film bags 10 being conveyed are laid one by one on the belt of the belt conveyor. The film bags 10 are rectangular bags with their openings facing to the right.

[0072] like Figure 1 As shown, the carton conveying mechanism 3 is located on the lower right side of the frame 1, and is used to convey cartons 20 in the front-to-back direction. In this embodiment, the carton conveying mechanism 3 can also be a belt conveyor.

[0073] like Figure 1 As shown, the bag spreading mechanism 4 is located in the lower middle part of the frame 1. The bag spreading mechanism 4 includes a bag spreading suction cup 41 and a bag spreading air supply device. The bag spreading air supply device is used to draw or supply air into the bag spreading suction cup 41.

[0074] like Figure 1 As shown, the pickup mechanism 5 is located above the film bag transport mechanism 2, and the pickup mechanism 5 is used to pick up the film bag 10 transported by the film bag transport mechanism 2. Figure 5 As shown, the pickup mechanism 5 includes a pickup lifting rod 51, a pickup suction cup 52, and a pickup air supply device. The pickup lifting rod 51 can be a hydraulic cylinder or a pneumatic cylinder, with its output end facing downwards. The pickup suction cup 52 is fixedly installed at the output end of the pickup lifting rod 51. The pickup air supply device is used to draw or supply air into the pickup suction cup 52.

[0075] like Figure 3 and Figure 4As shown, the moving mechanism 6 is located on the upper part of the frame 1. The moving mechanism 6 is used to drive the picking mechanism 5 to move in the left-right direction above the bag unfolding mechanism 4. The moving mechanism 6 includes a moving base 61, a moving motor 62, a gear 63, and a rack 64. The moving base 61 is slidably connected to the upper part of the frame 1 in the left-right direction. The moving motor 62 is fixedly installed on the moving base 61. The gear 63 is fixedly installed on the output shaft of the moving motor 62. The rack 64 extending in the left-right direction is fixedly installed on the upper part of the frame 1. The rack 64 meshes with the gear 63. The moving base 61 is fixedly connected to the upper part of the picking lifting rod 51.

[0076] like Figure 1 As shown, when the mobile motor 62 is started, if the output shaft of the mobile motor 62 drives the gear 63 to rotate clockwise, because the gear 63 meshes with the rack 64, the gear 63 can drive the mobile motor 62, the moving base 61, and the pickup mechanism 5 to move together along the rack 64 from left to right; if the output shaft of the mobile motor 62 drives the gear 63 to rotate counterclockwise, the gear 63 can drive the mobile motor 62, the moving base 61, and the pickup mechanism 5 to move together along the rack 64 from right to left.

[0077] like Figure 8 As shown, an ear plate seat 11 is fixedly installed on the upper right side of the frame 1. The ear plate seat 11 is rotatably connected to a rotating shaft 12 via a bearing. The rotating shaft 12 is fixedly connected to one end of the swing arm 7.

[0078] like Figure 5 As shown, the rotating mechanism is located on the upper right side of the frame 1, and is used to drive the swing arm 7 to rotate. The rotating mechanism includes a rotating motor 81, which is fixedly installed on the upper right side of the frame 1, and the output shaft of the rotating motor 81 is fixedly connected to the rotating shaft 12.

[0079] When the rotating motor 81 is started, the output shaft of the rotating motor 81 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the swing arm 7 to rotate together, thereby achieving the function of driving the swing arm 7 to rotate.

[0080] like Figure 6 and Figure 7As shown, the transfer mechanism 9 is located at the end of the swing arm 7 away from the frame 1. The transfer mechanism 9 includes an adsorption cylinder 91, a transfer lifting rod 92, and a transfer air supply device. The adsorption cylinder 91 includes a first cylinder 911 and a second cylinder 912 connected to each other. The first cylinder 911 is thicker than the second cylinder 912. The first cylinder 911 and the second cylinder 912 are integral structures. The lower surface of the first cylinder 911 has several first through holes 9111, which are inclined outwards. The side of the second cylinder 912 has several second through holes 9121. The transfer lifting rod 92 can also be a hydraulic cylinder or a pneumatic cylinder. One end of the transfer lifting rod 92 is fixedly connected to the swing arm 7, and the other end of the transfer lifting rod 92 is fixedly connected to the first cylinder 911. The transfer air supply device is used to draw or supply air into the adsorption cylinder 91.

[0081] The working process of an environmentally friendly cardboard box bagging device is as follows:

[0082] (1) The film bag transmission mechanism 2 transmits the film bag 10 in the forward and backward direction. When the film bag 10 is transmitted to the bottom of the pickup suction cup 52, the output end of the pickup lifting rod 51 extends downward, driving the height of the pickup suction cup 52 to decrease. After the height of the pickup suction cup 52 decreases, the pickup suction cup 52 picks up the film bag 10.

[0083] (2) When the pick-up suction cup 52 picks up the film bag 10, the moving motor 62 drives the gear 63 to rotate clockwise. The gear 63 drives the moving motor 62, the moving seat 61, the pick-up lifting rod 51, the pick-up suction cup 52 and the film bag 10 to move together along the rack 64 from left to right.

[0084] (3) When the pick-up suction cup 52 moves together with the film bag 10 above the spreading suction cup 41, the moving motor 62 stops, and the spreading suction cup 41 adsorbs the lower surface of the film bag 10.

[0085] (4) When the bag spreading suction cup 41 adsorbs the lower surface of the film bag 10, the output end of the picking lifting rod 51 retracts, driving the picking suction cup 52 to lift the upper surface of the film bag 10, thereby increasing the distance between the bag spreading suction cup 41 and the picking suction cup 52, so that the bag opening of the film bag 10 can be opened.

[0086] (5) When the bag opening of the film bag 10 is opened, the output end of the picking lifting rod 51 stops retracting, and the rotating motor 81 drives the swing arm 7 to rotate clockwise, so that the swing arm 7 rotates from the horizontal state to the vertical state. When the swing arm 7 rotates to the vertical state, the adsorption cylinder 91 on the swing arm 7 gradually inserts into the inside of the film bag 10.

[0087] (6) When the adsorption cylinder 91 is inserted into the membrane bag 10, the rotating motor 81 stops, the pick-up suction cup 52 and the bag spreading suction cup 41 cancel the adsorption state of the membrane bag 10, and then the adsorption cylinder 91 adsorbs the membrane bag 10.

[0088] (7) After the adsorption cylinder 91 adsorbs the film bag 10, the rotating motor 81 drives the swing arm 7 to rotate counterclockwise, so that the swing arm 7 returns from the vertical state to the horizontal state, so that the adsorption cylinder 91 carrying the film bag 10 is located above the carton conveying mechanism 3. At the same time, the moving motor 62 carries the gear 63 to rotate counterclockwise, driving the pickup lifting rod 51 and the pickup suction cup 52 to return to the top of the film bag conveying mechanism 2.

[0089] (8) When the carton 20 on the carton conveying mechanism 3 is conveyed to the bottom of the adsorption cylinder 91, the output end of the transfer lifting rod 92 extends downward, so that the adsorption cylinder 91 carries the film bag 10 into the carton 20. The transfer air supply device cancels the negative pressure state of the adsorption cylinder 91 and fills the adsorption cylinder 91 with air. The air blown out from the first through hole 9111 blows the bag mouth of the film bag 10 toward the box mouth of the carton 20, so that the bag mouth of the film bag 10 is turned upside down. The air blown out from the second through hole 9121 blows the film bag 10 toward the inner wall of the carton 20, thus completing the bagging.

[0090] (9) After the bagging is completed, the output end of the transfer lifting rod 92 retracts and resets, and the transfer gas supply equipment is shut down.

[0091] As can be seen from the above process, in the carton environmental protection bagging device of this embodiment, a mechanized method is used to realize the actions of opening the film bag 10 and bagging the carton 20, with uniform force. This avoids tearing the film bag 10 due to uneven force when manually opening the film bag 10 or bagging the carton 20, thereby reducing the waste of the film bag 10 and saving resources and protecting the environment.

[0092] Furthermore, in this embodiment of the carton environmental protection bagging device, the picking suction cup 52, the spreading suction cup 41, and the adsorption cylinder 91 all contact the film bag 10 by adsorption, without any sharp structures contacting the film bag 10, which further reduces the risk of damage to the film bag 10 and further facilitates saving and environmental protection.

[0093] Furthermore, in the carton environmental protection bagging device of this embodiment, because mechanized bagging is achieved, not only can bagging efficiency be improved, but labor costs can also be saved.

[0094] In addition, the carton environmental protection bagging device of this embodiment picks up the film bags 10 one by one, so this device is suitable for bagging individual film bags 10, but not for rolls of film bags 10.

[0095] Example 2:

[0096] This embodiment 2 illustrates the specific structure of the bag-spreading air supply device, the transfer air supply device, and the pickup air supply device from embodiment 1.

[0097] like Figure 10As shown, the bag-spreading air supply equipment, the transfer air supply equipment, and the pickup air supply equipment all include a blower 301, a vacuum pump 302, an air supply pipe 304, an exhaust pipe 303, an air supply valve 306, an exhaust valve 305, and a connecting pipe 307. The air supply pipe 304 is installed at the outlet of the blower 301, and the air supply valve 306 is installed on the air supply pipe 304. The exhaust pipe 303 is installed at the exhaust port of the vacuum pump 302, and the exhaust valve 305 is installed on the exhaust pipe 303. The end of the air supply pipe 304 furthest from the blower 301 and the end of the exhaust pipe 303 furthest from the vacuum pump 302 are both connected to one end of the connecting pipe 307. The other end of the connecting pipe 307 is connected to the pickup suction cup 52, the bag-spreading suction cup 41, or the suction cylinder 91.

[0098] When the exhaust valve 305 is closed and the supply valve 306 is open, the blower 301 can supply air to the pickup suction cup 52, the bag spreading suction cup 41, or the adsorption cylinder 91 through the supply pipe 304 and the connecting pipe 307, so that the film bag 10 adsorbed on the pickup suction cup 52, the bag spreading suction cup 41, or the adsorption cylinder 91 can detach. When the supply valve 306 is closed and the exhaust valve 305 is open, the vacuum pump 302 can draw air from the pickup suction cup 52, the bag spreading suction cup 41, or the adsorption cylinder 91 through the exhaust pipe 303 and the connecting pipe 307, so that the pickup suction cup 52, the bag spreading suction cup 41, or the adsorption cylinder 91 can adsorb the film bag 10.

[0099] Example 3:

[0100] This embodiment 3 is an improvement upon embodiment 1 or embodiment 2:

[0101] like Figures 1-9 As shown, in this embodiment 3, the bag spreading mechanism 4 also includes a bag spreading lifting rod 42. The bag spreading lifting rod 42 can be a hydraulic cylinder or a pneumatic cylinder. The output end of the bag spreading lifting rod 42 is set upward, and a bag spreading suction cup 41 is fixedly installed on the output end of the bag spreading lifting rod 42.

[0102] The setting of the bag spreading lifting rod 42 can adjust the height of the bag spreading suction cup 41 so that it is level with the height of the film bag conveying mechanism 2 at different heights. When the moving mechanism 6 drives the pickup suction cup 52 to move above the bag spreading suction cup 41, the distance between the bag spreading suction cup 41 and the pickup suction cup 52 can be reduced, so that the film bag 10 adsorbed on the pickup suction cup 52 is closer to the bag spreading suction cup 41, so that the bag spreading suction cup 41 can easily adsorb the lower surface of the film bag 10, thus improving the flexibility of use.

[0103] Example 4:

[0104] This embodiment 4 is a further improvement on embodiment 1, embodiment 2, or embodiment 3:

[0105] like Figure 1As shown, in this embodiment 4, the end of the film bag conveying mechanism 2 is provided with a film bag feeding mechanism 40. The film bag feeding mechanism 40 includes a storage box 401 and a support 402, with the storage box 401 fixedly installed on the upper end of the support 402. The storage box 401 contains stacked film bags 10. Figure 3 As shown, the bottom of the storage bag box 401 is provided with a window 4011, and the side wall of the storage bag box 401 is provided with a discharge port 4012. The discharge port 4012 is connected to the window 4011, and the bottom layer of film bag 10 contacts the belt of the belt conveyor 2, which is the film bag conveying mechanism, from the window 4011.

[0106] When the belt conveyor 2, which serves as the film bag conveying mechanism, is started, the bottom layer of film bag 10 in the storage bag box 401 comes into contact with the belt of the belt conveyor through the window 4011. Therefore, by utilizing the friction between the belt of the belt conveyor and the lower surface of the film bag 10, the belt of the belt conveyor can convey the bottom layer of film bag 10 in the storage bag box 401 from the discharge port 4012.

[0107] As can be seen from the above process, the film bag feeding mechanism 40 enables mechanical feeding of the film bag 10 without the need for manual feeding, which helps to further reduce the labor intensity of workers.

[0108] Furthermore, such as Figure 2 As shown, the storage bag box 401 has a limiting plate 403 on one side with a discharge port 4012. The limiting plate 403 has an elongated hole 4031 and a screw 4032 inside the elongated hole 4031. The screw 4032 is fixedly connected to the side of the storage bag box 401. A nut 4033 is threaded onto the screw 4032. The limiting plate 403 is sandwiched between the side wall of the storage bag box 401 and the nut 4033.

[0109] By adjusting the height of the limiting plate 403, the height of the discharge port 4012 exposed can be limited to the bottom layer of the film bag 10 in the storage box 401, which helps to improve the accuracy of the film bag 10 transmission.

[0110] When adjusting the limiting plate 403, first loosen the nut 4033, then slide the limiting plate 403 downwards. At this time, the elongated hole 4031 and the screw 4032 will have relative displacement. After the limiting plate 403 is adjusted, tighten the nut 4033 to fix the current height of the limiting plate 403.

[0111] Furthermore, in order to prevent two adjacent film bags 10 from sticking together, an air nozzle (not shown in the figure) is provided in the storage box 401. The air nozzle blows air onto the stacked film bags 10 to increase the gap between two adjacent film bags 10 and reduce the risk of two adjacent film bags 10 sticking together.

[0112] Example 5:

[0113] This embodiment 5 is a further improvement on embodiment 1, embodiment 2, embodiment 3, or embodiment 4:

[0114] like Figure 11 As shown in the figure, the carton environmental protection bagging device of this embodiment 5 also includes a control module 50 and a detection module 60. The detection module 60, the film bag conveying mechanism 2, the carton conveying mechanism 3, the pickup lifting rod 51, the pickup air supply device, the moving motor 62, the bag unfolding air supply device, the rotating motor 81, the transfer lifting rod 92, and the transfer air supply device are all electrically connected to the control module 50.

[0115] like Figure 11 As shown, the detection module 60 includes a first camera 601, a second camera 602, a first air pressure sensor 603, a second air pressure sensor 604, a third air pressure sensor 605, a first distance sensor 606, a second distance sensor 607, a third distance sensor 608, a first photoelectric sensor 609, and a second photoelectric sensor 6010.

[0116] like Figure 8 As shown, the first camera 601 is installed on the lower left side of the frame 1, facing the film bag transfer mechanism 2. The first camera 601 is used to capture images of whether a film bag 10 has arrived below the pickup suction cup 52. The control module 50 stores images of the film bag 10 being transferred to the area below the pickup suction cup 52. The control module 50 can compare the images captured by the first camera 601 with the stored images. If the comparison matches, it indicates that a film bag 10 has been transferred to the area below the pickup suction cup 52.

[0117] like Figure 8 As shown, the second camera 602 is installed on the lower right side of the frame 1, facing the carton conveying mechanism 3. The second camera 602 is used to capture images of whether a carton 20 has arrived below the suction cylinder 91. The control module 50 stores images of the carton 20 being conveyed to the area below the suction cylinder 91. The control module 50 can compare the images captured by the second camera 602 with the stored images. If the comparison matches, it indicates that a carton 20 has been conveyed to the area below the suction cylinder 91.

[0118] like Figure 1As shown, a first air pressure sensor 603 is mounted on the pickup suction cup 52. The first air pressure sensor 603 is used to detect the air pressure inside the pickup suction cup 52. The control module 50 has set set air pressures P1 and P2, where set air pressure P2 is greater than set air pressure P1. When the air pressure detected by the first air pressure sensor 603 received by the control module 50 is equal to or lower than the set air pressure P1, it indicates that the pickup suction cup 52 is in a negative pressure state, at which point the pickup suction cup 52 can pick up the film bag 10. When the air pressure detected by the first air pressure sensor 603 received by the control module 50 is equal to or higher than the set air pressure P2, the pickup suction cup 52 is in a positive pressure state, at which point the pickup suction cup 52 can detach from the film bag 10.

[0119] like Figure 6 As shown, a second air pressure sensor 604 is mounted on the bag-spreading suction cup 41. The second air pressure sensor 604 is used to detect the air pressure inside the bag-spreading suction cup 41. The control module 50 has set air pressures P3 and P4, where set air pressure P4 is greater than set air pressure P3. When the air pressure detected by the second air pressure sensor 604 received by the control module 50 is equal to or lower than the set air pressure P3, the bag-spreading suction cup 41 is in a negative pressure state, at which point the bag-spreading suction cup 41 can adhere to the film bag 10. When the air pressure detected by the second air pressure sensor 604 received by the control module 50 is equal to or higher than the set air pressure P4, the bag-spreading suction cup 41 is in a positive pressure state and can detach from the film bag 10.

[0120] like Figure 1 As shown, a third pressure sensor 605 is installed on the adsorption cylinder 91, and is used to detect the air pressure inside the adsorption cylinder 91. The control module 50 has set pressure P5 and pressure P6, where pressure P6 is greater than pressure P5. When the control module 50 receives a pressure from the third pressure sensor 605 that is equal to or lower than pressure P5, the adsorption cylinder 91 is in a negative pressure state and can adsorb the membrane bag 10; when the control module 50 receives a pressure from the third pressure sensor 605 that is equal to or higher than pressure P6, the adsorption cylinder 91 is in a positive pressure state and can detach from the membrane bag 10.

[0121] like Figure 8 As shown, the first distance sensor 606 is installed on the side of the pickup lifting rod 51. The first distance sensor 606 is used to measure the distance to the upper surface of the pickup suction cup 52. The control module 50 has set distances S1 and S2. If the distance signal received by the control module 50 from the first distance sensor 606 is equal to the set distance S1, it means that the pickup suction cup 52 has been lowered to a height where it can adsorb the film bag 10, that is, it has been lowered into position. If the distance signal received by the control module 50 from the first distance sensor 606 is equal to the set distance S2, it means that the height of the pickup suction cup 52 has risen to a height where the distance between the pickup suction cup 52 and the bag unfolding suction cup 41 is sufficient to unfold the opening of the film bag 10.

[0122] like Figure 8 As shown, the second distance sensor 607 is installed on the upper left side of the frame 1. The second distance sensor 607 is used to measure the distance to the left side of the moving seat 61. The control module 50 has set distances S3 and S4. If the distance signal received by the control module 50 from the second distance sensor 607 is equal to the set distance S3, it means that the moving seat 61, carrying the pickup lifting rod 51 and the pickup suction cup 52, has moved above the film bag transfer mechanism 2. If the distance signal received by the control module 50 from the second distance sensor 607 is equal to the set distance S4, it means that the moving seat 61, carrying the pickup lifting rod 51 and the pickup suction cup 52, has moved above the unfolding suction cup 41.

[0123] like Figure 8 As shown, the third distance sensor 608 is installed on the side of the transfer lifting rod 92. The third distance sensor 608 is used to measure the distance to the upper surface of the adsorption cylinder 91. The control module 50 has set distances S5 and S6. If the distance signal received by the control module 50 from the third distance sensor 608 is equal to the set distance S5, it indicates that the adsorption cylinder 91 has risen to the height above the cardboard box 20. If the distance signal received by the control module 50 from the third distance sensor 608 is equal to the set distance S6, it indicates that the adsorption cylinder 91 has descended to the height below the cardboard box 20.

[0124] like Figure 8 As shown, the first photoelectric sensor 609 is mounted on the upper part of the frame 1. When the swing arm 7 rotates to the vertical position, the first photoelectric sensor 609 can transmit the signal that the swing arm 7 has rotated to the vertical position to the control module 50.

[0125] like Figure 8 As shown, the second photoelectric sensor 6010 is mounted on the upper part of the frame 1. When the swing arm 7 rotates to a horizontal position, the second photoelectric sensor 6010 can transmit a signal that the swing arm 7 is in a horizontal position to the control module 50.

[0126] Example 6:

[0127] A control method for an environmentally friendly cardboard box bagging device includes the following steps:

[0128] S1. When the control module 50 receives the signal transmitted from the film bag 10 to the bottom of the pickup suction cup 52, the control module 50 not only controls the film bag transmission mechanism 2 to stop, but also controls the output end of the pickup lifting rod 51 to extend downward, so that the height of the pickup suction cup 52 is reduced.

[0129] S2. When the control module 50 receives the signal that the pickup suction cup 52 has descended to the position, the control module 50 not only controls the output end of the pickup lifting rod 51 to stop extending, but also controls the pickup air supply device to extract the air in the pickup suction cup 52, so that the pickup suction cup 52 picks up the film bag 10.

[0130] S3. When the control module 50 receives the signal that the pick-up suction cup 52 is adsorbing the film bag 10, the control module 50 not only controls the pick-up air supply device to maintain the state of the pick-up suction cup 52 adsorbing the film bag 10, but also controls the moving motor 62 to drive the gear 63 to rotate clockwise. The gear 63 drives the moving motor 62, the moving seat 61, the pick-up lifting rod 51, the pick-up suction cup 52 and the film bag 10 to move together along the rack 64 from left to right.

[0131] S4. When the control module 50 receives the signal that the pickup suction cup 52 has moved above the bag spreading suction cup 41, the control module 50 not only controls the moving motor 62 to stop, but also controls the bag spreading air supply device to extract the air in the bag spreading suction cup 41, so that the bag spreading suction cup 41 adsorbs the lower surface of the film bag 10.

[0132] S5. When the control module 50 receives the signal that the bag spreading suction cup 41 adsorbs the film bag 10, the control module 50 not only controls the bag spreading air supply device to maintain the state of the bag spreading suction cup 41 adsorbing the film bag 10, the control module 50 also controls the output end of the pickup lifting rod 51 to retract, driving the pickup suction cup 52 to lift up the upper surface of the film bag 10, thereby increasing the distance between the bag spreading suction cup 41 and the pickup suction cup 52, so that the bag opening of the film bag 10 can be opened.

[0133] S6. When the control module 50 receives the signal that the bag opening of the film bag 10 is open, the control module 50 not only controls the output end of the pickup lifting rod 51 to stop retracting, but also controls the rotating motor 81 to drive the swing arm 7 to rotate clockwise, so that the swing arm 7 rotates from the horizontal state to the vertical state. When the swing arm 7 rotates to the vertical state, the adsorption cylinder 91 on the swing arm 7 gradually inserts into the interior of the film bag 10.

[0134] S7. When the control module 50 receives the swing arm 7 turning to the vertical state, the control module 50 not only controls the rotating motor 81 to stop, but also controls the pickup suction cup 52 and the bag spreading suction cup 41 to cancel the adsorption state of the film bag 10. Then the control module 50 controls the transfer air supply equipment to extract the air in the adsorption cylinder 91, so that the adsorption cylinder 91 adsorbs the film bag 10.

[0135] S8. When the control module 50 receives the signal that the adsorption cylinder 91 adsorbs the film bag 10, the control module 50 not only controls the rotation motor 81 to drive the swing arm 7 to rotate counterclockwise, so that the swing arm 7 returns from the vertical state to the horizontal state, so that the adsorption cylinder 91 carrying the film bag 10 is above the carton conveying mechanism 3, the control module 50 also controls the moving motor 62 to drive the gear 63 to rotate counterclockwise, so as to drive the pickup lifting rod 51 and the pickup suction cup 52 to return to the top of the film bag conveying mechanism 2.

[0136] S9. When the control module 50 receives a signal that the swing arm 7 has been reset to the horizontal state, the control module 50 controls the rotation motor 81 to stop.

[0137] S10. When the control module 50 receives a signal that the moving seat 61 carrying the picking lifting rod 51 and the picking adsorption plate has been reset above the film bag transmission mechanism 2, the control module 50 not only controls the moving motor 62 to stop, but also controls the film bag transmission mechanism 2 to continue transmitting the film bag 10.

[0138] S11. When the control module 50 receives the signal that the carton 20 is transmitted to the bottom of the adsorption cylinder 91, the control module 50 not only controls the carton transmission mechanism 3 to stop, but also controls the output end of the transfer lifting rod 92 to extend downward, so that the adsorption cylinder 91 carries the film bag 10 into the carton 20.

[0139] S12. When the control module 50 receives the signal that the adsorption cylinder 91 has entered the carton 20, the control module 50 controls the transfer air supply device to fill the adsorption cylinder 91 with air. The air blown out from the first through hole 9111 blows the bag opening of the film bag 10 toward the box opening of the carton 20, so that the bag opening of the film bag 10 is turned upside down. The air blown out from the second through hole 9121 blows the film bag 10 toward the inner wall of the carton 20, thus completing the bagging.

[0140] S13. When the control module 50 receives the signal that the carton 20 has completed bagging, the control module 50 not only controls the transfer air supply equipment to shut down, but also controls the output end of the transfer lifting rod 92 to retract and reset, so that the adsorption cylinder 91 rises and resets.

[0141] S14. When the control module 50 receives the signal that the adsorption cylinder 91 has risen and reset, the control module 50 not only controls the transfer lifting rod 92 to stop, but also controls the carton conveying mechanism 3 to continue conveying.

[0142] As can be seen from the above process, the control method of the carton environmental protection bagging device in this embodiment can perform time-limited mechanized bagging operation without manual intervention, which helps to reduce the labor intensity of workers, save labor costs, improve bagging efficiency, and reduce the risk of tearing the film bag 10 due to uneven manual force, which is conducive to saving and environmental protection.

[0143] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
