[0054] Unless specifically stated or defined otherwise, the term "and / or" used in the present invention 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 left and right directions mentioned below. Figure 1 The projection direction itself is consistent.

[0056] like Figures 1 to 7As shown, this embodiment provides a boxed product packing line, including a frame 11, a conveying mechanism 12, a material dividing mechanism 13, a feeding mechanism 14, a sorting mechanism 15, a paper feeding mechanism 16, and a box sealing mechanism 17. The frame 11 extends from the back to the front, and the frame 11 acts as a keel. The frame 11 is welded by a hollow square tube, and the middle is convenient for routing and laying air pipes. The conveying mechanism 12 is installed on the frame 11. The conveying mechanism 12 has a conveying channel, and the conveying channel conveys the boxed product from the back to the front. In this embodiment, the boxed product is a boxed milk bag.

[0057] The material distribution mechanism 13 has a plurality of material distribution channels 1301 located on the conveying channel and connected to the conveying channel. Each material distribution channel 1301 extends from the back to the front, and each material distribution channel 1301 is arranged in sequence and is located above a portion of the conveying channel. After the milk bag is sent to the material distribution channel 1301, it is transported from the back to the front under the action of the conveying mechanism 12.

[0058] The feeding mechanism 14 has a feeding channel 1401, which is used for feeding 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 product group 30 of 4X6 specifications 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 them. Then the distribution mechanism 13 controls the number of milk bags that go out of the distribution channel 1301 each time, so that a number of product groups 30 of 4X6 specifications can be formed, and finally the several product groups 30 are packed in sequence.

[0059] The sorting mechanism 15 is used to divide the boxed products into several product groups 30 and sort them neatly. The width of each distribution channel 1301 is slightly larger than the width of the milk bag, and the partition between the distribution channels 1301 has a certain thickness. Therefore, the milk bags of each product group 30 are not tightly attached after coming out of the distribution channel 1301. At this time, the milk bags need to be sorted so that the multiple milk bags are attached together in the front-to-back direction and the left-to-right direction, so as to form product groups 30 distributed in an array.

[0060] The paper feeding mechanism 16 is used to feed the box paper 20 to the conveying channel and place the box paper 20 on the moving path of the boxed product. The paper feeding mechanism 16 is used to feed the box paper 20, which is in the state of a sheet of paper after the box is unfolded. After the paper feeding mechanism 16 feeds the box paper 20 to the conveying channel, the product group 30 composed of multiple milk bags falls into the main area of ​​the box paper 20, which is the non-edge area of ​​the paper box. The box body can be formed by folding and sealing the edges of the box paper 20. The box sealing mechanism 17 is used to fold the box paper 20 into a box body that wraps the product group 30 and seal the box.

[0061] The material distribution mechanism 13, the sorting mechanism 15, the paper feeding mechanism 16, and the sealing mechanism 17 are arranged in sequence on the frame 11 along the conveying path of the conveying channel. When the boxed product packaging production line is working, the milk bags are first transported one by one to the feeding channel 1401 of the feeding mechanism 14, and then the feeding mechanism 14 rotates to send the milk bags to the appropriate material distribution channel 1301. Under the action of the conveying mechanism 12, the milk bags pass through the material distribution mechanism 13, the sorting mechanism 15, and the sealing mechanism 17 in sequence. After the milk bags come out of the material distribution channel 1301, they are neatly sorted by the sorting mechanism 15 to form a product group 30, and then the paper feeding mechanism 16 sends the box paper 20 to the moving path of the product group 30, so that the product group 30 falls on the box paper 20 and moves to the sealing machine together with the box paper 20. Finally, the sealing mechanism 17 folds and seals the box paper 20 to complete the packaging of the boxed products. The entire packaging process does not require manual participation, which greatly improves the packaging efficiency of the boxed products. 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 by manual or mechanical hands. The various components and boxes of the cartoning machine take up a large space, the structure of the equipment is complex and the utilization rate is not high, and the function of fast cartoning cannot be realized. Moreover, the types of packaging products are becoming more and more abundant, which cannot meet the growing and diversified needs of people. It is inconvenient to adjust the packaging styles of different products, resulting in low reliability and high limitations in use. The boxed product cartoning line of this embodiment can solve the problems of complex structure and imperfect functions of the existing cartoning machines, and realize the function of fast adjustment and fast cartoning.

[0062] In one embodiment, the feeding mechanism 14 includes a rotating frame 1402 rotatably mounted on the frame 11, a first driver 1403 drivingly connected to the rotating frame 1402, and a first feeder 1404 having a first conveyor belt. The feeding channel 1401 is formed on the first conveyor belt, and one end of each distribution channel 1301 is located on the rotation path of the first conveyor belt. The milk bag can be sent to the distribution channel 1301 through the first conveyor belt. The first driver 1403 is a motor, which drives the rotating frame 1402 to rotate, so that the first conveyor belt can be connected to any distribution channel 1301 according to the distribution requirements.

[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 conveyor belt is sleeved on the first driving pulley and the first driven pulley. The swing frame is connected to the first conveyor belt, and the first driver 1403 is connected to the first driving pulley in a transmission manner. There are two second driving pulleys and two driven pulleys, which are rotatably mounted on the rotating frame 1402, and the second driving pulley is sleeved on the second driving pulley and the second driven pulley. The two second driven pulleys are coaxially connected to the push pulley 1405, and the two push pulleys 1405 are arranged at intervals. The second driving pulley is driven to rotate by installing a motor on the rotating frame 1402, so that the two push pulleys 1405 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 feeding channel 1401 of the feeding 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 with intervals from the back to the front with respect to the frame 11. 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. The front end of the rotating frame 1402 performs a 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 material distribution channel 1301 is formed between adjacent partition plates 1304. The second driver 1303 is mounted on the frame 11, and the second driver 1303 is connected to the baffle plate 1302 in a transmission manner so that the baffle plate 1302 is close to or away from the material distribution channel 1301. The second driver 1303 is a cylinder, which is mounted on the frame 11 through a cylinder seat, and the baffle plate 1302 can be driven to move up and down by the cylinder. According to the quantity of milk bags of 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, which facilitates 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 seat is slidably mounted on the gantry, and a hand wheel 1305 and a screw are provided on the gantry, and the hand wheel 1305 and the screw are connected to the cylinder seat through transmission to realize the up and down movement of the cylinder seat, thereby realizing the up and down movement of the second driver 1303. When in use, the packing production line can rotate the hand wheel 1305 according to the height of the milk bag, so that the blocking plate 1302 can block milk bags of different heights.

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

[0068] Optionally, the material distribution structure further includes a second sensor for detecting and calculating the number of milk bags at the outlet of the material distribution channel 1301. There are multiple second sensors corresponding to multiple material distribution channels 1301 one by one, and the second sensors are located above the material distribution channels 1301. The second sensor can detect the number of milk bags entering the sorting mechanism 15 from the material distribution 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, so that the width of the material distribution channel 1301 changes due to the jitter of the production line, which can avoid the smoothness of milk bag transportation from decreasing.

[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 conveying chain 1501 sleeved on 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 conveying face is tensioned by a tensioning wheel. The first driving sprocket, the first driven sprocket, and the first conveying chain 1501 are provided on both sides of the conveying channel. The two ends of the push rod 1505 are respectively connected to the two first conveying chains 1501. Under the action of the third driver 1502, the speed of the push rod 1505 moving from the back to the front is greater than the conveying speed of the conveying mechanism 12. The push rod 1505 pushes the milk bags in the same product group 30 to move forward and close to each other, completing the alignment of the milk bags in the front and rear directions. After completing the sorting, the push rod 1505 moves upward, then moves backward, and then moves downward to the rear of the next group of product groups 30, and finally repeats the above sorting process. The first gathering rod 1503 and the second gathering rod 1504 are both installed on the frame 11 and arranged at intervals 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 arranged in sequence along the moving path of the first conveying chain 1501. The third driver 1502 is connected to the first active sprocket to drive the push rod 1505 to push the boxed product along the conveying path of the conveying channel. When the push rod 1505 pushes the product group 30 forward, the product group 30 moves forward between the first gathering rod 1503 and the second gathering rod 1504. Since the distance between the first gathering rod 1503 and the second gathering rod 1504 gradually decreases, the milk packages in the same product group 30 move along the left and right directions, so that the milk packages are brought together and the milk is neatly arranged in the left and right directions.

[0071] Furthermore, guide wheels are rotatably mounted on the first gathering rod 1503 and the second gathering rod 1504. The guide wheels are arranged at intervals along the extension path of the conveying channel. The guide wheels on the first gathering rod 1503 and the guide wheels on the second gathering rod 1504 are arranged opposite to each other, so that the milk bags can be conveyed more smoothly under the action of the guide wheels.

[0072] In one embodiment, the paper feeding mechanism 16 includes a box frame 1601 provided on the frame 11, a second loader 1602 having a second conveyor belt and mounted on the box frame 1601, a placement rack 1603 having a placement portion 1604 and mounted on the box frame 1601, an adsorbent 1605 for adsorbing the box paper 20 on the second conveyor belt to the placement portion 1604, and a pusher 1606 for pushing the box paper 20 on the placement portion 1604 to the conveying passage. The adsorbent 1605 and the pusher 1606 are both mounted on the placement rack 1603. The box frame 1601 is used to store a plurality of box papers 20 stacked in sequence, and a plurality of paper boxes stacked in sequence are placed on the second conveyor belt. The adsorbent 1605 is a suction cup, and the adsorbent 1605 can move up and down, so that the box papers 20 on the box frame 1601 can be placed one by one on the placement portion 1604 on the placement rack 1603. The pusher 1606 is a cylinder / electric telescopic rod and other components. After the box paper 20 is placed on the placement portion 1604, the box paper 20 is sent to the conveying channel and is 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 also includes a paper pusher 1607, a limit seat 1608, a guide rod 1609, and a support guardrail 1610. The box frame 1601 has a paper outlet, and the paper pusher 1607 is installed on the second conveyor belt. The box frame 1601 is provided with a guide rod 1609, and the paper pusher 1607 is sleeved on the guide rod 1609 to achieve smooth sliding, thereby reducing the load of the second conveyor belt. A plurality of 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 to the paper outlet. The edge of the paper outlet is provided with a limit seat 1608, and the paper boxes 20 are placed to fall. When the absorber 1605 absorbs the paper boxes 20 and passes through the paper outlet and downwardly detaches from the box frame 1601, the edge of the paper boxes 20 is deformed so that it can detach from the box frame 1601 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 portion 1604 is tilted and gradually rises along the conveying path of the conveying channel. A support guardrail 1610 is provided at the lower end of the placement rack 1603 to prevent the box paper 20 from escaping from the placement portion 1604 due to gravity. The pusher 1606 can push the box paper 20 out at an angle, so that the milk packages of the product group 30 fall on the non-edge area of ​​the box paper 20, which facilitates the folding of the edge area of ​​the box paper 20 to form a box body.

[0075] In one embodiment, the carton sealing mechanism 17 includes an upper paper folding arm 1701 for folding part of the carton downward to form an upper sealing part, a rear paper folding arm 1702 for folding part of the carton downward to form a rear sealing part, a first side paper 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 with the rear sealing part, and a second side paper 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 bag of the product group 30 falls onto the box paper 20, the product group 30 presses the box paper 20 onto the conveying channel so that the box paper 20 lies flat on the conveying channel. The upper folding paper arm 1701 can make horizontal reciprocating motions forward and backward. Through the backward motion of the upper folding paper arm 1701 and the forward motion of the box paper 20, the upper folding paper arm 1701 can fold the front end of the box paper 20 upward and backward to form an upper sealing portion. The rear folding paper arm 1702 moves upward to fold the rear end of the box paper 20 upward to form a rear sealing portion, and the rear sealing portion is bonded to the upper sealing portion. There are two first side folding paper arms 1703, which are respectively located on the two sides of the product group 30. The first side folding paper arm 1703 bends the front end and the rear end of the left and right sides of the box paper 20 backward and forward respectively to form two first side sealing portions bonded to the two sides of the product group 30. In addition, when the front or rear end of the first side folding arm 1703 on the left and right sides of the box paper 20 is long enough, it can also be bent forward or backward to form a folded portion to seal the left and right sides of the product group 30. The upper folding arm 1701, the rear folding arm 1702, and the first side folding arm 1703 can work simultaneously or step by step and in any order.

[0077] The upper glue sprayer 1705 is used to spray sealant on the upper sealing part and / or the rear sealing part, and then under the action of the sealant, the pressing arm 1707 presses the upper sealing part and the rear sealing part together. The side glue sprayer 1706 is used to spray sealant on the first side sealing part, and the second side folding arm 1704 first folds part of the paper box downward and / or folds downward to form a second side sealing part. In this embodiment, the upper edge and the lower edge of the paper box are bent close to each other to form abutment on the first side sealing part, and then under the action of the sealant, the second side folding arm 1704 presses the second side sealing part on the first side sealing part to achieve the bonding of the first side sealing part and the second side sealing part, and the box sealing mechanism 17 completes the box sealing. The upper glue sprayer 1705 and the side glue sprayer 1706 can both spray hot melt glue to achieve the sealing of the box body.

[0078] Optionally, the conveying mechanism 12 includes a first carrier belt 1201 and 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, and the box sealing mechanism 17 is located above the first carrier chain 1202. There are two first carrier chains 1202 and they are arranged from left to right. A third conveying chain 1714 is arranged between the two first carrier chains 1202. The third conveying chain 1714 or a conveyor belt is used to realize the cyclic movement of the third conveying chain 1714 through a third driving sprocket and a third driven sprocket. The rear folding arm 1702 is installed on the third conveying chain 1714, and the third conveying chain 1714 drives the rear folding arm 1702 to circulate. The length of the third conveying chain 1714 in the front-to-back direction is less than the length of the first carrier chain 1202 in the front-to-back direction. In this way, the rear folding arm 1702 is driven by the third conveying chain 1714 to bend the rear end of the box paper 20 upward, and then push the box paper 20 and the milk bag forward together for a certain distance, and then the rear folding arm 1702 moves downward and then moves backward to perform the next folding. The first carrier chain 1202 circulates, and there are multiple chain sleeves 1203 and they are arranged on the first carrier chain 1202 at intervals along the moving path of the first carrier chain 1202.

The rotating plate and the fixed plate are arranged in sequence from back to front, the fixed plate is fixed to the frame 11, the rotating plate is rotatably mounted on the frame 11, and the rotating axis of the rotating plate is vertically arranged. When the box paper 20 passes through the first side folding arm 1703, it first passes through the fixed plate, and the fixed plate supports the front edges of the left and right sides of the box paper 20 so that the front ends of the left and right sides of the box paper 20 are bent backward to form a first side sealing portion, and then the rotating plate rotates forward so that the rear ends of the left and right sides of the box paper 20 are bent forward to form another first side sealing portion, so as to facilitate the bonding of the second side sealing portion with the first side sealing 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 the back to the front. The arc plate is bent upward from the front to the back to facilitate the box paper 20 to enter between the first side paper folding arm 1703 and the first carrier chain 1202. Then, under the action of the straight plate, the upper sealing part is pressed on the rear sealing part.

[0082] Furthermore, in order to increase the area of ​​the upper seal portion pressed on the rear seal portion, the box 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, and after the rear seal portion is formed, the upper end of the rear seal portion is located on the rotation path of the folding arm 1713, so that the upper end of the rear seal portion is bent downward to form a sealing portion horizontally attached to the upper surface of the product group 30, and then the first side folding arm 1703 presses the upper seal portion on the sealing portion.

The second conveying chain 1709 is cyclically moved by the second driving sprocket and the second driven sprocket. Along the moving path of the second conveying chain 1709, the first positioning seat 1710 and the second positioning seat 1711 are alternately arranged.

[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 at the rear end of the second conveying chain 1709 is smaller than the detour diameter at the front end of the second conveying chain 1709, and the box is clamped into the box clamping gap 1712 from the rear end of the second conveying chain 1709. The detour diameter at 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, and the box leaves the box clamping gap 1712 from the front end of the second conveying chain 1709. The detour diameter at the front end of the second conveying chain 1709 is larger, which is convenient for loosening the box that has been sealed and conveyed.
