[0036] This embodiment discloses a liquid package packaging machine, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, may include:

[0037] A carton supply device 10, the carton supply device 10 being used for supplying cartons for liquid package packaging;

[0038] The packing and conveying unit 40, one end of the packing and conveying unit 40 is adjacent to the carton supply device 10; the carton supply device 10 supplies the cartons onto the packing and conveying unit 40;

[0039] The liquid package supply device 50, the liquid package supply device is arranged on one side of the packing and conveying unit 40; the liquid package supply device supplies the liquid packages into the cartons on the packing and conveying unit 40;

[0040] The first partition supply device 20, the first partition supply device 20 is arranged on one side of the packing and conveying unit 40; the first partition supply device 20 supplies the first partitions between the cartons and the liquid packages on the packing and conveying unit 40; the first partition supply device 20 includes a first partition forming part 23 and a first partition handling part 24; the first partition forming part 23 includes a first folding part 232, a forming and positioning part 231, and a second folding part 233; the first folding part 232 is rotatably connected to one side of the forming and positioning part 231 along the length direction of the packing and conveying unit 40; the second folding part 233 is rotatably connected to the other side of the forming and positioning part 231 along the length direction of the packing and conveying unit 40; the first partition handling part 24 is used for handling the first partitions formed by the first partition forming part 23 into the cartons on the packing and conveying unit 40.

[0041] In this embodiment, the liquid package is a sealed package containing liquid, which can include a cuboid milk package. During the process of packing and transporting the liquid packages, it is easy to cause losses due to bumps. To reduce the loss rate of the liquid packages, a protective partition can be provided between the liquid packages and the cartons. At present, the degree of automation of the equipment is relatively high, and most factories use automated equipment to pack the liquid into boxes, such as Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, a liquid package packing machine is used to pack liquid packages into boxes. The liquid package packing machine may include a carton supply device 10, a packing conveyor section 40, a liquid package supply device 50, and a first partition supply device 20. The carton supply device 10, the first partition supply device 20, and the liquid package supply device 50 are sequentially arranged on the periphery of the packing conveyor section 40 along the length direction of the packing conveyor section 40. The carton supply device 10 may include a carton supply conveyor section 11 and a carton handling section 12. The end of the carton supply conveyor section 11 may be adjacent to the starting end of the packing conveyor section 40. The starting end of the packing conveyor section 40 may be located above, below, or at the same level as the end of the carton supply conveyor section 11, but the two are not directly connected. The cartons on the carton supply conveyor section 11 need to be transported to the packing conveyor section 40 by the carton handling section 12. The time for the carton supply device 10 to supply a single carton is different from the time required for the packing conveyor section 40 and other related workstations to process a single carton. The time for the carton supply device 10 to supply a single carton may be less than the time for the packing conveyor section 40 and other related workstations to process the cartons. Therefore, multiple packing conveyor sections 40 may be provided at the end of the carton supply device 10 to improve work efficiency. Alternatively, the cartons supplied by the carton supply device 10 may be partially stored, and when the carton supply device 10 has problems, the stored cartons may be supplied to the packing conveyor section 40 to improve the overall stability of the system. The packing conveyor section 40 is used to transport the cartons to various workstations on its periphery for packing work. A first partition supply device 20 is provided on one side of the packing conveyor section 40. The first partition supply device 20 is used to fold the first partition board into a U-shaped first partition and place the formed first partition into the carton to reduce the loss rate of the liquid packages in the carton. In some other embodiments, such as Figure 4 and Figure 5 As shown, the liquid package supply device 50 may include a liquid package supply conveyor section 51 and a liquid package handling section 52. The liquid package supply conveyor section 51 is arranged on the side of the first partition supply device 20 away from the carton supply device 10 along the length direction of the packing conveyor section 40. The liquid package supply conveyor section 51 may transport the liquid packages and bond multiple liquid packages into a group. The liquid package handling section 52 is provided above the liquid package supply conveyor section 51. The liquid package handling section 52 may place the multiple liquid packages bonded into a group into the first partition in the carton to complete the packing of the liquid packages. In some other embodiments, such as Figure 6 As shown, the liquid package packing machine may further include a machine frame 70. The machine frame 70 is provided on the outer contour of the entire liquid package packing machine. The machine frame 70 may support each component of the liquid package packing machine.

[0042] Such as Figure 2 and Figure 3As shown, the first partition supply device 20 may include a first partition handling part 24 and a first partition forming part 23. The first partition board may be a rectangular double-layer cardboard, and there are two creases parallel to the short side of the rectangular body and symmetrically arranged on the partition board. The first partition forming part 23 is used to fold the partition board along the creases into a U-shaped partition. The first partition handling part 24 is used to grab the first partition formed by the first partition forming part 23 and place it in a carton on the conveyor belt of the carton packing conveyor part 40. The first partition forming part 23 includes a first folding part 232, a second folding part 233 and a forming positioning part 231. The forming positioning part 231 may be provided with a vacuum chuck that sucks the first partition board, and is used to position the first partition board. The first folding part 232 and the second folding part 233 are arranged at both ends of the positioning part along the length direction of the carton packing conveyor part 40. The first folding part 232 includes a rotating plate rotatably connected to one end of the positioning part and a driving device connected to the rotating plate. The driving device may be a hydraulic cylinder, and the rotating plate is driven to move through a telescopic rod; the driving device may also be a motor, and the rotating plate is driven to move through a rotating shaft. The driving device drives the rotating plate to rotate α degrees from the horizontal state along one end of the positioning part, causing the first partition board to be folded, forming a U-shaped first partition. After the first folding part 232 folds the first partition board, the first partition board will rebound a certain distance, so α can be slightly greater than 90 degrees to offset the rebounding distance and make the forming more standard. The structure of the second folding part 233 may be the same as that of the first folding part 232. The carton packing conveyor part 40 includes a positioning device that can position the carton. The positioning device positions the carton at both ends of the carton along the length direction of the carton packing conveyor part 40. To avoid interference of the positioning device, a certain distance needs to be left between two adjacent cartons. Above the first partition supply device 20, there is an engine and a bearing plate for carrying the engine, and it has a certain dimension along the length direction of the carton packing conveyor part 40. In summary, a certain distance also needs to be left between the forming positioning parts 231 corresponding to two adjacent first partitions along the length direction of the carton packing conveyor part 40. When placing the first partition board on the forming positioning part 231, the long side of the first partition board may be parallel to the length direction of the carton packing conveyor part 40 (that is, the corresponding first partition forming part 23 arranges the first folding part 232, the forming positioning part 231 and the second folding part 233 in sequence along the length direction of the carton packing conveyor part 40), which can effectively utilize the space between two adjacent first partitions, reduce the dimension of the first partition forming part 23 in the width direction of the carton packing conveyor part 40, thereby reducing the overall width of the liquid package packaging machine and improving the floor area ratio of the liquid package packaging machine.

[0043] In some embodiments, such as Figure 7As shown, the first partition handling unit 24 includes a second horizontal movement unit 241, a second vertical movement unit 242, a rotational movement unit 243, and a second grasping unit 244; the second horizontal movement unit 241, the second vertical movement unit 242, the rotational movement unit 243, and the second grasping unit 244 are connected in sequence; during the process of the first partition handling unit 24 transporting the first partition formed by the first partition forming unit 23 into the carton on the packing conveyor unit 40, the rotational movement unit 243 drives the first partition to rotate a set angle.

[0044] In this embodiment, as Figure 7 shown, the first partition handling unit 24 may include a second horizontal movement unit 241, a second vertical movement unit 242, a rotational movement unit 243, and a second grasping unit 244. The second horizontal movement unit 241, the second vertical movement unit 242, the rotational movement unit 243, and the second grasping unit 244 are connected in sequence. The second grasping unit 244 may include a vacuum suction cup that has suction force on the first partition. The second grasping unit 244 can adsorb the first partition through the vacuum suction cup, thereby fixing the position of the first partition. A number of connecting rods may be provided between the second grasping unit 244 and the rotational movement unit 243. One end of the connecting rod is fixedly connected to the second grasping unit 244, and the other end is fixedly connected to the rotational movement unit 243. The fixed connection method may be threaded connection or welding. During the process of the first partition handling unit 24 transporting the first partition formed by the first partition forming unit 23 into the carton on the packing conveyor unit 40, the rotational movement unit 243 drives the first partition on the second grasping unit 244 to rotate a set angle. The driving method of the rotational movement unit 243 may be that the motor and the connecting rod are rotationally connected, and the connecting rod is driven to move by the telescopic rod, thereby driving the rotational movement unit 243 to rotate. The rotational movement unit 243 is fixedly connected to the second vertical movement unit 242, and the second vertical movement unit 242 moves vertically, thereby driving the first partition to move vertically. The driving method may be electric drive or pneumatic device drive. The second vertical movement unit 242 is fixedly connected to the second horizontal movement unit 241, and the second horizontal movement unit 241 moves horizontally, thereby driving the first partition to move horizontally. The driving method may be motor drive or pneumatic device drive.

[0045] In some embodiments, as Figure 7 shown, the rotational movement unit 243 drives the first partition to rotate at an angle of 90 degrees.

[0046] In this embodiment, as Figure 7As shown, the rotary motion part 243 drives the first partition to rotate by 90 degrees. To reduce the width of the conveyor belt of the packing conveyor part 40 and save costs, the cartons used for packing can be placed on the conveyor belt with their long sides parallel to the length direction of the packing conveyor part 40. After being formed by the first partition forming part 23, the first partition is smaller in the dimension parallel to the length direction of the packing conveyor part 40. After rotating 90 degrees, it corresponds to the long side direction of the carton, facilitating its placement into the carton.

[0047] In some embodiments, as Figure 7 and Figure 8 shown, the first partition supply device 20 further includes a first partition board storage part 21 and a first partition board handling part 22; the first partition board storage part 21 is arranged on one side of the first partition forming part 23 away from the packing conveyor part 40; the first partition board handling part 22 is arranged on the periphery of the first partition board storage part 21; the first partition board handling part 22 transports the first partition boards stored in the first partition board storage part 21 to the first partition forming part 23.

[0048] In this embodiment, as Figure 7 and Figure 8 shown, the first partition supply device 20 may include a first partition board storage part 21 and a first partition board handling part 22. The first partition board storage part is arranged on one side of the first partition forming part 23 away from the packing conveyor part 40. The first partition board storage part can store and supply the first partition boards, enabling the packaging machine to work continuously. The placement mode of the first partition boards can be overlapping placement with their long sides parallel to the length direction of the packing conveyor part 40, facilitating the grasping and placement by the first partition board handling part 22. The first partition board handling part 22 is arranged on the periphery of the first partition board storage part 21 and can be arranged above the side of the first partition board storage part 21. The first partition board handling part 22 can grasp the first partition boards stored in the first partition board storage part and place the first partition boards with their long sides parallel to the length direction of the packing conveyor part 40 on the first partition forming part 23.

[0049] In some embodiments, as Figure 7 shown, the first partition board handling part 22 includes a first horizontal motion part 221, a first vertical motion part 222, and a first grasping part 223; the first horizontal motion part 221, the first vertical motion part 222, and the first grasping part 223 are connected in sequence.

[0050] In this embodiment, as Figure 7As shown, the first partition board handling part 22 includes a first horizontal movement part 221, a first vertical movement part 222, and a first grasping part 223. The first horizontal movement part 221, the first vertical movement part 222, and the first grasping part 223 are connected in sequence. The first grasping part 223 can be provided with a vacuum suction cup that has suction force on the first partition, and can play a role in fixing the first partition board. The first vertical movement part 222 is fixedly connected to the first grasping part 223. The first vertical movement part 222 moves in the vertical direction, thereby driving the first partition board to move in the vertical direction. The first vertical movement part 222 can be driven by a motor or a pneumatic device. The first horizontal movement part 221 is fixedly connected to the first vertical movement part 222. The first horizontal movement part 221 moves horizontally, thereby driving the first partition board to move in the horizontal direction. The first horizontal movement part 221 can be driven by a motor or a pneumatic device.

[0051] In some embodiments, as Figure 8 shown, the first partition board storage part 21 includes an annular drive chain 211, a drive shaft 212, a driven shaft 213, a first lifting plate 214, and a fixed support plate 216; the drive shaft 212 is arranged at one end of the annular drive chain 211; the driven shaft 213 is arranged at the other end of the annular drive chain 211; the drive shaft 212 drives the annular drive chain 211 to move circumferentially around the drive shaft 212 and the driven shaft 213; one end of the first lifting plate 214 is fixedly connected to the annular drive chain 211; the fixed support plate 216 is adjacent to the lower end part in the vertical direction of the annular drive chain 211; an avoidance groove can be arranged on the fixed support plate 216; the first lifting plate 214 passes through the avoidance groove of the fixed support plate 216 during the movement along with the annular drive chain 211; at least the space on one side of the annular drive chain 211 swept by the first lifting plate 214 is set as the storage space for the first partition board.

[0052] In this embodiment, as Figure 8As shown, the first partition board storage part 21 includes an annular drive chain 211, a drive shaft 212, a driven shaft 213, a first lifting plate 214, and a fixed support plate 216. The drive shaft 212 and the driven shaft 213 can be respectively adjacent to both ends of the first partition board storage part 21 along the length direction. The drive shaft 212 can be arranged at one end far from the discharge port of the first partition board storage part 21, and the driven shaft 213 can be arranged at one end close to the discharge port of the first partition board storage part 21. The drive shaft 212 is connected with a drive device. When placed at the lower end, it will not block the discharge port, and it makes the center of gravity of the first partition board storage part lower and the stability higher. The drive shaft 212 drives the annular drive chain 211 to move around the drive shaft 212 and the driven shaft 213. A number of sprockets are sleeved on the drive shaft 212, and an equal number of corresponding sprockets are sleeved on the driven shaft 213. Multiple annular drive chains 211 are arranged on the drive shaft 212 and the driven shaft 213. The annular drive chain 211 meshes with the sprockets on the drive shaft 212 and the corresponding sprockets on the driven shaft 213 at the same time. The drive equipment drives the drive shaft 212 to rotate, thereby driving the sprockets and the driven shaft 213 to move. The first lifting plate 214 is fixedly connected with the annular drive chain 211 and moves together with the annular drive chain 211. The first lifting plate 214 can support the stored first partition board and move upward under the drive of the drive shaft 212, facilitating the handling of the first partition board. The fixed support plate 216 is adjacent to the lower end of the annular drive chain 211 in the vertical direction and is arranged above the lower end of the annular drive chain 211 in the vertical direction. Avoidance grooves are formed on the fixed tray. When the first lifting plate 214 moves along with the annular conveyor chain, it can pass through the avoidance grooves of the fixed tray without interference, enabling the first lifting plate 214 to move freely along with the annular conveyor chain without being blocked. The fixed tray can store the first partition board. When the first lifting plate 214 moves to a high position along with the annular conveyor chain, a gap will be generated between the fixed tray and the first lifting plate 214. The first partition board can be placed on the fixed tray for the next lifting of the first lifting plate 214, which can reduce the time for placing the first partition board and improve work efficiency. The long side of the first partition board is placed on the first lifting plate 214 along the length direction of the packing conveyor part 40. Compared with the long side of the first partition board being placed on the first lifting plate 214 along the width direction of the packing conveyor part 40, the size required by the first partition board storage part 21 along the width direction of the packing conveyor part 40 is lower, the torque formed between the first lifting plate 214 and the first partition board is shorter, and the force required for the first lifting plate 214 to lift the first partition board is smaller. At least the space on one side of the annular drive chain 211 swept by the first lifting plate 214 is set as the storage space for the first partition board and can be used to store the first partition board.

[0053] In some embodiments, such as Figure 9As shown, the first partition supply device 20 further includes a second lifting plate 215; one end of the second lifting plate 215 is fixedly connected to the annular drive chain 211; the first lifting plate 214 and the second lifting plate 215 are arranged at intervals on the outer contour track of the annular drive chain 211.

[0054] In this embodiment, as Figure 9 shown, the first partition supply device 20 further includes a second lifting plate 215. The second lifting plate 215 is fixedly connected to the annular drive chain 211. The first lifting plate 214 and the second lifting plate 215 are arranged at intervals on the outer contour track of the annular drive chain 211. By setting two lifting plates to rotate with the annular drive chain 211 to support and drive the first partition plate in sequence, when the first lifting plate 214 leaves the storage space of the first partition plate, the other lifting plate can support and drive the first partition plate. The interval time for the first partition plate storage part 21 to supply the first partition plate can be shortened, and the working efficiency is higher.

The second partition supply device 30 is arranged on the side of the first partition supply device 20 away from the carton supply device 10, and its structure can be similar to that of the first partition supply device 20, so it will not be elaborated here. After the first partition and the liquid package are packed into the case, there is still a large empty space in the carton, and the second partition can be packed. During packing, the second partition is arranged directly above the first partition, and its groove faces the opening of the carton. By setting the second partition supply device 30 for packing, the space of the carton can be fully utilized, materials can be saved, and the overall packing efficiency of the liquid package packaging machine can be improved.
