[0054] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0055] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The left and right directions are consistent with the Figure 1 The up and down directions are consistent with the Figure 1 The projection direction itself is consistent.

[0056] like Figures 1 to 7As shown, this embodiment provides a boxing line for boxed products, comprising a frame 11, a conveying mechanism 12, a material dividing mechanism 13, a loading mechanism 14, a finishing mechanism 15, a paper feeding mechanism 16, and a box sealing mechanism 17. Frame 11 extends from back to front and serves as a keel. Frame 11 is welded from hollow square tubes, with a central space for routing wiring and air pipes. Conveying mechanism 12 is mounted on frame 11. Conveying mechanism 12 has a conveying channel that transports the boxed products from back to front. In this embodiment, the boxed products are boxed milk bags.

[0057] The distributing mechanism 13 includes a plurality of distributing channels 1301 located on and connected to the conveying channel. Each distributing channel 1301 extends from back to front and is arranged sequentially and located above a portion of the conveying channel. After the milk bag is delivered to the distributing channel 1301, it is transported from back to front by the conveying mechanism 12.

[0058] The feeding mechanism 14 has a feeding channel 1401, which is used to feed milk bags. After the milk bags are produced, they are transported to the feeding channel 1401 of the feeding mechanism 14, and then transported to the distribution channel 1301 under the action of the feeding mechanism 14. The feeding mechanism 14 is rotatably mounted on the frame 11 to switch the feeding channel 1401 to connect to any distribution channel 1301. The feeding mechanism 14 can rotate when working, so that the milk bags can be transported to the appropriate distribution channel 1301. For example, when a 4X6 product group 30 is needed, more than six milk bags are transported to four of the distribution channels 1301, or more than four milk bags are transported to six of the distribution channels. Then, the distribution mechanism 13 controls the number of milk bags that exit the distribution channel 1301 each time, so that several 4X6 product groups 30 can be formed. Finally, the several product groups 30 are packed in sequence.

[0059] The arranging mechanism 15 is used to divide the boxed products into several product groups 30 and arrange them neatly. The width of each distribution channel 1301 is slightly larger than the width of the milk bag, and the partitions between the distribution channels 1301 have a certain thickness. Therefore, the milk bags in each product group 30 are not tightly packed together after exiting the distribution channel 1301. In this case, the milk bags need to be arranged so that they are tightly packed together in the front-to-back direction and the left-to-right direction, thereby forming an array of product groups 30.

[0060] The paper feed mechanism 16 is used to deliver the carton paper 20 to the conveyor channel and position it in the path of the boxed products. The paper feed mechanism 16 transports the carton paper 20, which is in a sheet-like state after the box is unfolded. After the paper feed mechanism 16 delivers the carton paper 20 to the conveyor channel, the product group 30, consisting of multiple milk packages, falls into the main body area of ​​the carton paper 20. The main body area is the non-edge area of ​​the carton. The edges of the carton paper 20 are then folded and sealed to form the box body. The box sealing mechanism 17 folds the carton paper 20 into a box body that encloses the product group 30 and seals the box.

[0061] The sorting mechanism 13, the arranging mechanism 15, the paper feeding mechanism 16, and the carton sealing mechanism 17 are sequentially arranged on the frame 11 along the conveying path of the conveyor channel. During the boxed product packaging line, milk bags are first transported one by one to the loading channel 1401 of the loading mechanism 14. The loading mechanism 14 then rotates to deliver the milk bags to the appropriate sorting channel 1301. Under the action of the conveying mechanism 12, the milk bags pass through the sorting mechanism 13, the arranging mechanism 15, and the carton sealing mechanism 17 in sequence. After the milk bags emerge from the sorting channel 1301, they are neatly arranged by the arranging mechanism 15 to form product groups 30. The paper feeding mechanism 16 then delivers the carton paper 20 to the moving path of the product group 30, allowing the product group 30 to fall onto the carton paper 20 and move together with the carton paper 20 to the carton sealing machine. Finally, the carton sealing mechanism 17 folds and seals the carton paper 20, completing the packaging of the boxed products. The entire packaging process requires no human intervention, greatly improving the efficiency of boxed product packaging. In some other cartoning machines, the box paper is first folded into a box body, and then the product is placed in the box body manually or by a robot. The various components and the box body of the cartoning machine take up a lot of space, the equipment structure is complex, and the utilization rate is low, which makes it impossible to achieve fast cartoning. Moreover, the variety of packaged products is increasing, which cannot meet people's growing and diverse needs. It is inconvenient to adjust the packaging style of different products, resulting in low reliability and high usage limitations. The boxed product cartoning line of this embodiment can solve the problems of complex structure and imperfect function of existing cartoning machines, and realize the rapid adjustment and fast cartoning function.

[0062] In one embodiment, the feeding mechanism 14 includes a turret 1402 rotatably mounted on the frame 11, a first driver 1403 in transmission connection with the turret 1402, and a first loader 1404 comprising a first conveyor belt. A feeding channel 1401 is formed on the first conveyor belt, with one end of each feeding channel 1301 located along the first conveyor belt's rotational path. The first conveyor belt delivers milk bags to the feeding channels 1301. The first driver 1403 is a motor that drives the turret 1402, allowing the first conveyor belt to connect to any feeding channel 1301 according to feeding needs.

[0063] Furthermore, the feeding mechanism 14 also includes a first transmission belt, a first driving pulley, a first driven pulley, a second transmission belt 1406, a second driving pulley, a second driven pulley, a guide frame 1407, and a support frame 1408. The first driving pulley and the first driven pulley are both rotatably mounted on the guide frame 1407, and the first transmission belt is sleeved around the first driving pulley and the first driven pulley. The swing frame is connected to the first transmission belt, and the first driver 1403 is in transmission connection with the first driving pulley. There are two second driving pulleys and two second driven pulleys, each rotatably mounted on the rotating frame 1402, and the second driving pulley is sleeved around the second driving pulley and the second driven pulley. The two second driven pulleys are coaxially connected to a push pulley 1405, and the two push pulleys 1405 are arranged at intervals. A motor is installed on the rotating frame 1402 to drive the second driving pulley to rotate, thereby causing the two push pulleys 1405 to rotate. The distance between the two pushing wheels 1405 is slightly smaller than the width of the milk bag. In this way, when it is necessary to switch the distribution channel 1301, the motor stops rotating, and the two pushing wheels 1405 block the milk bag. When the loading channel 1401 of the loading mechanism 14 is aligned with the appropriate distribution channel 1301, the motor drives the two pushing wheels 1405 to rotate so that the milk bag is pushed out by the pushing wheels 1405 using friction.

[0064] The support frame 1408 and the guide frame 1407 are arranged spaced apart from the frame 11 from back to front. The rear end of the rotating frame 1402 is rotatably installed on the support frame 1408. The guide frame 1407 has an arc guide plate, and the front end of the rotating frame 1402 performs circular motion along the arc guide plate.

[0065] In one embodiment, the material distribution mechanism 13 includes a baffle plate 1302, a second driver 1303, and a plurality of partition plates 1304. The plurality of partition plates 1304 are arranged in sequence from left to right, and a distribution channel 1301 is formed between adjacent partition plates 1304. The second driver 1303 is mounted on the frame 11. The second driver 1303 is connected to the baffle plate 1302 by transmission so that the baffle plate 1302 moves closer to or away from the distribution channel 1301. The second driver 1303 is a cylinder, which is mounted on the frame 11 through a cylinder seat. The cylinder can drive the baffle plate 1302 to move up and down. According to the number of milk bags required for the product group 30, the baffle plate 1302 is driven to descend to block the milk bags, so that the milk bags can be sent to the sorting mechanism 15 in batches, making it convenient for the sorting mechanism 15 to quickly sort out multiple product groups 30.

[0066] Optionally, a gantry is provided on the frame 11, and the cylinder base is mounted on the gantry in a vertically slidable manner. The gantry is provided with a handwheel 1305 and a screw. The handwheel 1305 and the screw are connected to the cylinder base through a transmission connection to achieve the up and down movement of the cylinder base, thereby achieving the up and down movement of the second driver 1303. During use, the cartoning production line can rotate the handwheel 1305 according to the height of the milk bags, so that the material blocking plate 1302 can block milk bags of different heights.

[0067] In one embodiment, the distributing structure further includes a first sensor 1307 for detecting and counting the number of milk bags in the distributing channel 1301. There are multiple first sensors 1307 corresponding to multiple distributing channels 1301 one by one, and the first sensors 1307 are located above the distributing channels 1301.

[0068] Optionally, the distributing mechanism also includes a second sensor for detecting and counting the number of milk bags at the outlet of the distributing channel 1301. Multiple second sensors are provided, corresponding one to each of the distributing channels 1301. The second sensors are located above the distributing channels 1301. The second sensors can detect the number of milk bags entering the sorting mechanism 15 from the distributing mechanism 13, thereby ensuring the accuracy of the number of milk bags in the product group 30.

[0069] Furthermore, the material distribution mechanism 13 also includes a partition 1306. The upper end of each material distribution channel 1301 is provided with a partition 1306, and adjacent partition plates 1304 are connected by the partition 1306. In this way, it is possible to avoid the change in the width of the material distribution channel 1301 due to the vibration of the production line, which may cause the smoothness of the milk bag conveying to decrease.

[0070] In one embodiment, the sorting mechanism 15 includes a first driving sprocket rotatably mounted on the frame 11, a first driven sprocket rotatably mounted on the frame 11, a first conveyor chain 1501 sleeved around the first driving sprocket and the first driven sprocket, a third driver 1502, a first gathering rod 1503, a second gathering rod 1504, and a plurality of push rods 1505. The first conveyor chain is tensioned by a tensioning pulley. The first driving sprocket, the first driven sprocket, and the first conveyor chain 1501 are located on both sides of the conveying channel. The push rods 1505 are connected to the two first conveyor chains 1501 at their ends. Driven by the third driver 1502, the push rods 1505 move forward from the rear to the front at a speed greater than the conveying speed of the conveying mechanism 12. The push rods 1505 push the milk packages within the same product group 30 forward toward each other, aligning the packages in the front-to-back direction. After completing the sorting process, the push rods 1505 move upward, then backward, and then downward to the rear of the next product group 30, repeating the sorting process. The first gathering rod 1503 and the second gathering rod 1504 are both mounted on the frame 11 and spaced apart on the conveying channel. Along the conveying path of the conveying channel, the distance between the first gathering rod 1503 and the second gathering rod 1504 gradually decreases. A plurality of push rods 1505 are sequentially arranged along the moving path of the first conveyor chain 1501. The third driver 1502 is in transmission connection with the first active sprocket to drive the push rods 1505 to push the boxed products along the conveying path of the conveying channel. When the push rods 1505 push the product group 30 forward, the product group 30 moves forward between the first gathering rod 1503 and the second gathering rod 1504. As the distance between the first gathering rod 1503 and the second gathering rod 1504 gradually decreases, the milk packages within the same product group 30 move in the left-right direction, bringing the milk packages closer together and completing the neat arrangement of the milk in the left-right direction.

[0071] Furthermore, guide wheels are rotatably mounted on both the first and second gathering rods 1503, 1504. These guide wheels are spaced apart along the extended path of the conveying channel. The guide wheels on the first and second gathering rods 1503, 1504 are positioned opposite each other, ensuring smoother conveyance of the milk bags.

[0072] In one embodiment, the paper feeding mechanism 16 includes a box rack 1601 disposed on the frame 11, a second loader 1602 having a second conveyor belt and mounted on the box rack 1601, a placement rack 1603 having a placement portion 1604 and mounted on the box rack 1601, a suction element 1605 for sucking the paper boxes 20 on the second conveyor belt onto the placement portion 1604, and a pusher 1606 for pushing the paper boxes 20 on the placement portion 1604 into the conveying channel. Both the suction element 1605 and the pusher 1606 are mounted on the placement rack 1603. The box rack 1601 is used to store a plurality of stacked paper boxes 20. The plurality of stacked paper boxes are placed on the second conveyor belt. The suction element 1605 is a suction cup that can move up and down, thereby placing the paper boxes 20 on the box rack 1601 one by one on the placement portion 1604 of the placement rack 1603. The pusher 1606 is a component such as a cylinder / electric telescopic rod. After the box paper 20 is placed on the placement portion 1604, the box paper 20 is pushed onto the conveying channel and located on the moving path of the product group 30 under the pushing action of the pusher 1606.

[0073] Optionally, the paper feeding mechanism 16 further includes a paper pusher 1607, a stopper 1608, a guide rod 1609, and a support guardrail 1610. The box frame 1601 has a paper outlet, and the paper pusher 1607 is mounted on the second conveyor belt. The box frame 1601 is provided with a guide rod 1609. The paper pusher 1607 is sleeved on the guide rod 1609 to achieve smooth sliding, thereby reducing the load on the second conveyor belt. Multiple paper boxes 20 are placed between the paper pusher 1607 and the paper outlet. Under the action of the second conveyor belt, the paper boxes 20 are pushed out of the paper outlet. The edge of the paper outlet is provided with a stopper 1608 to prevent the paper boxes 20 from falling. When the absorber 1605 absorbs the paper boxes 20 and passes through the paper outlet downward to separate from the box frame 1601, the edge of the paper boxes 20 is deformed so that they can separate from the paper outlet. Finally, the absorber 1605 places the paper boxes 20 one by one on the placement rack 1603.

[0074] In one embodiment, the placement section 1604 is tilted, gradually rising along the conveying path of the conveyor channel. A support guardrail 1610 is provided at the lower end of the placement rack 1603 to prevent the carton paper 20 from falling off the placement section 1604 due to gravity. The pusher 1606 can tilt and push the carton paper 20, allowing the milk packages of the product group 30 to land on the non-edge area of ​​the carton paper 20, facilitating the folding of the edge area of ​​the carton paper 20 to form a box body.

[0075] In one embodiment, the carton sealing mechanism 17 includes an upper folding arm 1701 for folding part of the carton downward to form an upper sealing part, a rear folding arm 1702 for folding part of the carton downward to form a rear sealing part, a first side folding arm 1703 for folding part of the carton forward and / or backward to form a first side sealing part, an upper glue sprayer 1705 for spraying sealant on the upper sealing part and / or the rear sealing part, a side glue sprayer 1706 for spraying sealant on the first side sealing part, a pressing arm 1707 for pressing the upper sealing part and the rear sealing part, and a second side folding arm 1704 for folding part of the carton downward and / or folding downward to form a second side sealing part and pressing the second side sealing part on the first side sealing part.

[0076] After the milk package of the product group 30 falls onto the carton paper 20, the product group 30 presses the carton paper 20 onto the conveying channel, so that the carton paper 20 lies flat on the conveying channel. The upper folding arm 1701 can perform horizontal reciprocating motion forward and backward. Through the backward movement of the upper folding arm 1701 and the forward movement of the carton paper 20, the upper folding arm 1701 can fold the front end of the carton paper 20 upward and backward to form an upper seal. The rear folding arm 1702 moves upward to fold the rear end of the carton paper 20 upward to form a rear seal, which is bonded to the upper seal. There are two first side folding arms 1703, one on each side of the product group 30. The first side folding arms 1703 bend the front and rear ends of the carton paper 20 backward and forward, respectively, to form two first side seals bonded to the two sides of the product group 30. Alternatively, if the front or rear ends of the first side folding arms 1703 on either side of the paper 20 are sufficiently long, they can simply bend forward or backward to form a single folded portion to seal the left and right sides of the product group 30. The upper folding arm 1701, rear folding arm 1702, and first side folding arm 1703 can operate simultaneously or in separate steps, and in any order.

[0077] The upper glue sprayer 1705 is used to spray sealant onto the upper seal portion and / or the rear seal portion. Under the action of the sealant, the pressing arm 1707 presses the upper seal portion and the rear seal portion together. The side glue sprayer 1706 is used to spray sealant onto the first side seal portion. The second side folding arm 1704 first folds a portion of the carton downward and / or downward to form a second side seal portion. In this embodiment, the upper and lower edges of the carton are bent close to each other to form abutment against the first side seal portion. Then, under the action of the sealant, the second side folding arm 1704 presses the second side seal portion onto the first side seal portion to achieve bonding of the first and second side seal portions, and the box sealing mechanism 17 completes the box sealing. Both the upper glue sprayer 1705 and the side glue sprayer 1706 can spray hot melt adhesive to achieve box sealing.

[0078] Optionally, the conveying mechanism 12 includes a first carrier belt 1201, a first carrier chain 1202, and a chain sleeve 1203. The material distribution channel 1301 and the sorting mechanism 15 are located above the first carrier belt 1201. The box sealing mechanism 17 is located above the first carrier chain 1202. There are two first carrier chains 1202, spaced from left to right. A third conveyor chain 1714, or a conveyor belt, is located between the two first carrier chains 1202. The third conveyor chain 1714 is circulated by a third driving sprocket and a third driven sprocket. A rear folding arm 1702 is mounted on the third conveyor chain 1714, driving it in a circular motion. The third conveyor chain 1714 is shorter in the front-to-back direction than the first carrier chain 1202. This allows the third conveyor chain 1714 to drive the rear folding arm 1702 upward to fold the rear end of the carton 20, pushing the carton 20 and milk bag forward a certain distance. The rear folding arm 1702 then moves downward and then backward to perform the next folding operation. The first carrier chain 1202 is in a circular motion, with multiple chain sleeves 1203 arranged at intervals along its travel path. Plastic chain sleeves 1203 support the carton 20 and milk bag, preventing them from interfering with the coordination between the first carrier chain 1202 and the sprockets.

[0079] Optionally, a first side folding arm 1703 is provided on both the left and right sides of the conveying passage. The first side folding arm 1703 includes a rotating plate and a fixed plate arranged in sequence along the conveying path of the conveying passage. The rotating plate and the fixed plate are arranged in sequence from back to front, the fixed plate is fixed to the frame 11, and the rotating plate is rotatably mounted on the frame 11. The rotating axis of the rotating plate is arranged vertically. When the box paper 20 passes through the first side folding arm 1703, it first passes through the fixed plate. The fixed plate supports the front edges of the left and right sides of the box paper 20, causing the front ends of the left and right sides of the box paper 20 to bend backward to form a first side seal portion. Then, the rotating plate rotates forward, causing the rear ends of the left and right sides of the box paper 20 to bend forward to form another first side seal portion, facilitating the bonding of the second side seal portion to the first side seal portion.

[0080] Furthermore, the rotating plate is sickle-shaped, and the inner arc surface and the outer arc surface of the rotating plate are smoothly connected, with the inner arc surface facing the front end, so that the arc surface between the inner arc surface and the outer arc surface abuts against the box paper 20 to bend the box paper 20 without damaging the box paper 20.

[0081] Optionally, the pressing arm 1707 includes an arc plate and a straight plate connected in sequence from back to front. The arc plate bends upward from front to back to facilitate the entry of the box paper 20 between the first side folding arm 1703 and the first carrier chain 1202. Then, under the action of the straight plate, the upper sealing portion is pressed against the rear sealing portion.

[0082] Furthermore, in order to increase the area of ​​the upper seal pressing on the rear seal, the carton sealing mechanism 17 of the present application further includes a rotatably mounted folding arm 1713. The folding arm 1713 rotates from the rear to the front. After the rear seal is formed, the upper end of the rear seal is located on the rotation path of the folding arm 1713, so that the upper end of the rear seal is bent downward to form a sealing portion that is horizontally attached to the upper surface of the product group 30. Then, the first side folding arm 1703 presses the upper seal against the sealing portion.

[0083] Optionally, the second side folding arm 1704 can bend the upper and lower ends of the left side of the box paper 20 downward and upward, respectively, or can bend the upper and lower ends of the right side downward and upward, respectively. Second side folding arms 1704 are provided on both the left and right sides of the conveying channel. Each second side folding arm 1704 includes two pressure rods arranged in an "eight" shape. The distance between the two pressure rods decreases along the conveying path component of the conveying channel and then remains constant, so that the front ends of the two pressure rods can bend the upper and lower ends of the box paper 20 downward and upward, respectively, to form the second side seal portion.

[0084] The carton sealing mechanism 17 also includes a first pre-pressing arm and a second pre-pressing arm. The first pre-pressing arm pre-folds the carton downward to form an upper sealing portion, facilitating subsequent folding by the upper folding arm 1701. The second pre-pressing arm pre-folds part of the carton forward and / or backward to facilitate subsequent folding by the first side folding arm 1703.

[0085] In one embodiment, the carton sealing mechanism 17 further includes a feeder 1708 having a second conveyor chain 1709, a first positioning seat 1710 disposed on the second conveyor chain 1709, and a second positioning seat 1711 disposed on the second conveyor chain 1709. The first positioning seat 1710 and the second positioning seat 1711 are both located above the conveyor channel and spaced apart along the conveying path of the conveyor channel, with a box-clamping gap 1712 formed between the first positioning seat 1710 and the second positioning seat 1711. The second conveyor chain 1709 is circulated by a second driving sprocket and a second driven sprocket. The first positioning seat 1710 and the second positioning seat 1711 are alternately arranged along the moving path of the second conveyor chain 1709.

[0086] Optionally, along the moving path of the conveying channel, the detour diameter of the second conveying chain 1709 increases, that is, the detour diameter of the rear end of the second conveying chain 1709 is smaller than the detour diameter of the front end of the second conveying chain 1709, and the box body is clamped into the box clamping gap 1712 from the rear end of the second conveying chain 1709. The detour diameter of the rear end of the second conveying chain 1709 is smaller, which is convenient for the first positioning seat 1710 and the second positioning seat 1711 to clamp the box body, and the box body leaves the box clamping gap 1712 from the front end of the second conveying chain 1709. The detour diameter of the front end of the second conveying chain 1709 is larger, which is convenient for loosening the box body after sealing and conveying.

[0087] In one embodiment, the boxed product packing line further includes a controller 18. The conveying mechanism 12, the loading mechanism 14, the material sorting mechanism 13, the collating mechanism 15, the paper feeding mechanism 16, and the carton sealing mechanism 17 are all electrically connected to the controller 18. The controller 18 includes a control box and a control module installed in the control box. The control box is installed on the frame 11. The conveying mechanism 12, the loading mechanism 14, the material sorting mechanism 13, the collating mechanism 15, the paper feeding mechanism 16, and the carton sealing mechanism 17 are all electrically connected to the control module. Through the control module, the start and stop of the conveying mechanism 12, the loading mechanism 14, the material sorting mechanism 13, the collating mechanism 15, the paper feeding mechanism 16, and the carton sealing mechanism 17 can be controlled.

[0088] This embodiment further provides a boxed product packing method, based on the boxed product packing line of any of the above embodiments, the boxed product packing method includes the following steps:
