[0002] Traditional cartoning machines mostly use a linear conveying structure, and the carton blanks pass through the opening, loading and sealing stations in sequence along the linear conveying path. This type of design requires each station to be arranged linearly along the conveying direction, resulting in a large overall length of the equipment and high requirements for factory space, especially in a compact production environment. At the same time, the carton blank needs to complete the entire movement from the starting end to the discharge end, the travel between stations is long, and the single operation cycle time increases, which restricts the improvement of cartoning efficiency. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0022] Please refer to Figures 1 to 7 , and a rotary top-opening box loading machine provided by an embodiment of the present application will be described. The rotary top-opening box loading machine includes a frame 100, a turntable 200, a box loading assembly, and a transfer assembly. Among them: The turntable 200 is rotatably mounted on the frame 100 and forms a number of support arms 201 evenly distributed around its own axis; the cartoning assembly includes a magazine 300 for accommodating the carton blanks 1000, two folding mechanisms 400 respectively for unfolding the carton blanks 1000 into a state where they can be loaded from the top (i.e., unfolding to form cartons) and closing the cartons after loading, a loading mechanism 500 for loading the target material, and an output conveyor belt 600. The magazine 300, the folding mechanisms 400, the loading mechanism 500, and the output conveyor belt 600 are circumferentially spaced around the axis of the turntable 200; the transfer assembly includes a carton holder 700 for clamping the carton blanks 1000 and a carton loading mechanism 800 for transferring the carton blanks 1000 from the magazine 300 to the carton holder 700. The carton holder 700 is connected to the support arm 201 and is used to rotate with the turntable 200 so that the carton blanks 1000 can sequentially pass through the folding mechanism 400 for unfolding the carton blanks 1000 into a state where they can be loaded from the top, the loading mechanism 500, the folding mechanism 400 for closing the carton after loading, and reach the front end of the output conveyor belt 600. The carton loading mechanism 800 is arranged radially along the turntable 200 between the carton holder 700 and the magazine 300. In this embodiment, the output conveyor belt 600 can convey the packaged products to the target position. Here, the conveying direction of the output conveyor belt 600 is parallel to the radial direction of the turntable 200. When the carton holder 700 rotates to the position of the output conveyor belt 600, the carton holder 700 is aligned with the output conveyor belt 600. This embodiment also includes a pushing plate 601 for pushing the carton (i.e., the product) filled with materials from the carton holder 700 and pushing it along the bottom guide plate 406 to the output conveyor belt 600. It can be understood that the pushing plate can be driven by a linear driving device such as a cylinder or a linear module; at the same time, it can be understood that the loading mechanism 500 can adopt the mechanical hand structure of the prior art to pick up the target material from the feeding conveyor device and load it into the carton with the top open.

[0023] According to the above structure provided in the present embodiment, in the rotary disk type top opening cartoning machine provided in the present embodiment, the silo 300 for placing the carton blank 1000, the folding mechanism 400 for unfolding the carton blank 1000 to the top opening state and for closing the carton after loading, the loading mechanism 500 for loading the carton blank 1000 with the target material, and the discharge conveyor belt 600 are distributed at intervals around the axial direction of the rotary disk 200. The rotary disk 200 rotates around the axial direction and drives the support arms 201 and the carton holder 700 evenly distributed in the circumferential direction to move, so that the carton blank 1000 can form a circular circulation path between the silo 300, the folding mechanism 400, the loading mechanism 500 and the discharge conveyor belt 600. Compared with the traditional linear conveying structure, the compact distribution of each station around the rotary disk 200 in the present embodiment can significantly shorten the transfer stroke of the carton blank 1000, so that the rotary disk type top opening cartoning machine provided in the present embodiment can achieve a higher cartoning efficiency, which is far superior to the prior art.

[0024] In another embodiment of the present application, please refer to Figures 1 to 7 The box loading mechanism 800 includes a linear module 801, a moving seat 802 which is transmission-connected to the linear module 801 and can be driven by the linear module 801, a box blank taking seat 803 connected to the moving seat 802, a box taking suction cup 804 which is installed on the box blank taking seat 803 and can suck the carton blank 1000 from the hopper 300, and also includes a box fixing suction cup 805 which is connected to the carton holder 700 and can suck the carton blank 1000 from the box taking suction cup 804; the moving seat 802 is used to move along the radial direction of the turntable 200, and the axial directions of the box taking suction cup 804 and the box fixing suction cup 805 are parallel to the moving direction of the moving seat 802. Please refer to the following for details. Figure 6 As shown, after the box-taking suction cup 804 of this embodiment sucks the carton blank 1000 from the hopper 300, the box-taking seat 803 is driven by the linear module 801 arranged above the hopper 300 to move toward the carton holder 700. It can be understood here that the width of the box-taking suction cup 804 and the box-taking seat 803 is smaller than the width of the carton holder 700, so that the box-taking suction cup 804 and the box-taking seat 803 can pass through the carton holder 700 until the vertical surface (that is, the corresponding long side 1001) of the carton blank 1000 abuts against the fixed The box sucker 805 is sucked by the fixed box sucker 805, the box sucker 804 is released, and then the box sucker 804 and the box blank seat 803 continue to move forward a set distance to leave the track area where the carton holder 700 rotates with the turntable 200, and when the turntable 200 rotates through a division (that is, when the next empty carton holder 700 is aligned with the exit of the silo 300), the linear module 801 drives the box blank seat 803 and the box sucker 804 to pass through the carton holder 700 to reach the exit of the silo 300 for the next box removal, and so on. In this embodiment, the linear drive module can adopt a structure such as a linear motor commonly used in the art, which will not be described in detail here.

[0025] According to the above structure provided in this embodiment, by driving the moving seat 802 to linearly move along the radial direction of the turntable 200 through the linear module 801, the box blank picking seat 803 and the box blank picking suction cup 804 can be driven to adsorb the paper box blank 1000 from the magazine 300 along the shortest path. At the same time, since the axial directions of the box fixing suction cup 805 and the box blank picking suction cup 804 are parallel to the moving direction of the moving seat 802, it can be ensured that the paper box blank 1000 always maintains the same posture during the transfer process. In addition, the box blank picking suction cup 804 and the box fixing suction cup 805 can cooperate to complete the adsorption and release actions of the paper box blank 1000. After the box blank picking suction cup 804 clamps the paper box blank 1000 on the paper box clamping seat 700, the box fixing suction cup 805 can still stably fix the paper box blank 1000 in the paper box clamping seat 700 by adsorbing the paper box blank 1000, which is beneficial to further improving the box loading efficiency of the turntable type top-opening box loading machine in this embodiment.

[0026] In another embodiment of the present application, please refer to Figures 1 to 7 together. The paper box blank 1000 includes a long side 1001 and short sides 1002 connected to both sides of the long side 1001, and further includes a bottom cover 1003 connected to the long side 1001, a box bottom insertion tongue 1004 connected to the bottom cover 1003, and a front bottom folding tongue 1005 and a rear bottom folding tongue 1006 connected to the short sides 1002 on both sides; the folding box mechanism 400 for unfolding the paper box blank 1000 into a state capable of loading materials at the top includes an opening box guide plate 401, a bottom folding tongue mechanism for folding the front bottom folding tongue 1005 and the rear bottom folding tongue 1006 to be perpendicular to the short side 1002, and a bottom cover folding mechanism for folding the bottom cover 1003 to be perpendicular to the long side 1001 and inserting the box bottom insertion tongue 1004 into the interior of the paper box blank 1000. The opening box guide plate 401, the bottom folding tongue mechanism, and the bottom cover folding mechanism are sequentially spaced apart around the axial direction of the turntable 200 and are located between the magazine 300 and the loading mechanism 500; the opening box guide plate 401 forms an arc-shaped edge 411 with an axial direction parallel to the axial direction of the turntable 200. The arc-shaped edge 411 is arranged between the magazine 300 and the support arm 201 and is located on the moving path of the paper box blank 1000 so that the paper box blank 1000 can be unfolded into a state where the long side 1001 and the short side 1002 are perpendicular to each other during the process of abutting against the arc-shaped edge 411.

[0027] According to the above structure provided in this embodiment, in this embodiment, by arranging the arc-shaped edge 411 formed by the box-opening guide plate 401 on the movement path of the paper box blank 1000 between the magazine 300 and the support arm 201, the paper box blank 1000 can be naturally unfolded into a state where the long side 1001 is perpendicular to the short side 1002 in a manner of continuously abutting against the arc-shaped edge 411 during the process of being transferred from the magazine 300 to the paper box holder 700. This can eliminate the efficiency loss caused by the pause-type pressing and folding actions in the traditional box-opening station. In addition, since the bottom tongue folding mechanism and the bottom cover folding mechanism are sequentially distributed along the circumferential direction of the turntable 200, when the paper box blank 1000 rotates to the corresponding station, the bottom tongue folding mechanism and the bottom cover folding mechanism can respectively drive the front bottom folding tongue 1005, the rear bottom folding tongue 1006 and the bottom cover 1003 to be precisely folded in stages. Moreover, during the folding process of the bottom cover 1003, the box bottom inserting tongue 1004 can also be synchronously inserted into the interior of the paper box blank 1000, which is beneficial to further improving the box loading efficiency of the turntable type upper opening and box loading machine in this embodiment.

[0028] In another embodiment of the present application, please also refer to Figures 1 to 7 , the bottom tongue folding mechanism includes a front bottom closing small tongue guide rod 421 and a rear bottom closing small tongue plate 422; the front bottom closing small tongue guide rod 421 is formed into a shape that can guide the front bottom folding tongue 1005 and the rear bottom folding tongue 1006 to be folded perpendicular to the short side 1002. The rear bottom closing small tongue plate 422 and the front bottom closing small tongue guide rod 421 are sequentially arranged at intervals along the circumferential direction of the turntable 200 and are rotatably installed on the frame 100. The rotation center axis of the rear bottom closing small tongue plate 422 is perpendicular to the axial direction of the turntable 200 and forms a preset length so that the rear bottom closing small tongue plate 422 can drive the rear bottom folding tongue 1006 to enter above the guiding and folding path of the front bottom closing small tongue guide rod 421 during rotation.

[0029] According to the above structure provided in this embodiment, by matching the preset guiding shape of the front bottom tongue guide rod 421 with the moving path of the carton blank 1000, the front bottom folding tongue 1005 and the rear bottom folding tongue 1006 can be automatically folded along the guide rod contour to the target angle perpendicular to the short side 1002 without additional pauses for adjustment during the rotation of the turntable 200. Additionally, through the layout design of the preset length of the rear bottom tongue plate 422 and the rotation central axis perpendicular to the axial direction of the turntable 200, the rear bottom tongue plate 422 can push the rear bottom folding tongue 1006 accurately above the guiding and folding path of the front bottom tongue guide rod 421 during rotation, and then the front bottom tongue guide rod 421 completes the final folding when the carton blank 1000 travels with the carton clamping seat 700. In this way, it is ensured that the rear bottom folding tongue 1006 accurately enters above the front bottom tongue guide rod 421 during the continuous movement of the carton blank 1000 and is guided and folded by the front bottom tongue guide rod 421, which is beneficial to further improving the cartoning efficiency of the rotary top-opening cartoning machine in this embodiment. Here, it can be understood that the rear bottom tongue plate 422 can be driven by a motor or a rotary cylinder.

[0030] In another embodiment of the present application, please refer to Figures 1 to 7 , the bottom cover folding mechanism includes a folding box bottom guide rod 431 for guiding the folding of the bottom cover 1003 and a support bar 432 arranged side by side with the folding box bottom guide rod 431. The support bar 432 is arranged on the flipping path of the bottom cover 1003 and forms a preset folding corner edge so that after the bottom cover 1003 abuts against the support bar 432, the box bottom insertion tongue 1004 forms a shape capable of being inserted into the interior of the carton blank 1000; the bottom cover folding mechanism further includes a pressing bottom plate 433, a folding bottom insertion tongue plate 434, a first driving mechanism 435 drivingly connected to the pressing bottom plate 433, a second driving mechanism 436 drivingly connected to the folding bottom insertion tongue plate 434, and a third driving mechanism 437 drivingly connected to the support bar 432. The pressing bottom plate 433 and the folding bottom insertion tongue plate 434 are stacked. The moving path of the pressing bottom plate 433 interferes with the moving path of the bottom cover 1003 and can fold the bottom cover 1003 to be perpendicular to the long side 1001. The moving path of the folding bottom insertion tongue plate 434 interferes with the moving path of the box bottom insertion tongue 1004 and can cooperate with the pressing bottom plate 433 to insert the box bottom insertion tongue 1004 into the interior of the carton blank 1000. The output direction of the third driving mechanism 437 is perpendicular to the axial direction of the turntable 200 and can drive the support bar 432 to withdraw from or enter the flipping path area of the bottom cover 1003. In this embodiment, the first driving mechanism 435, the second driving mechanism 436, and the third driving mechanism 437 can all adopt common structures such as cylinders or motors in the art, and will not be elaborated here.

[0031] According to the above structure provided in this embodiment, by matching the preset guiding shape of the folding bottom guide rod 431 with the moving path of the paper box blank 1000, the bottom cover 1003 can be naturally folded along the guide rod contour to the preliminary position where it abuts against the folding edge during the process of following the turntable 200. At the same time, the support bar 432 can limit the position of the bottom cover 1003 through its preset folding edge. When the folding bottom tongue plate 434 rises and forces the box bottom tongue 1004 to form a pre-insertion posture when abutting against the support bar 432, it provides space prediction for subsequent precise insertion. After the third driving mechanism 437 drives the support bar 432 to withdraw from the folding path of the bottom cover 1003 along the direction perpendicular to the axial direction of the turntable 200 (this direction is also the horizontal longitudinal direction of the vertical surface formed after the pre-folding of the current box bottom tongue 1004), the pressing bottom plate 433 can be driven by the first driving mechanism 435 to apply pressure along the folding direction of the bottom cover 1003, so as to completely press the bottom cover 1003 to the vertical state, and at the same time make the box bottom tongue 1004 insert into the interior of the paper box blank 1000 along the guiding surface formed by the side wall of the folding bottom tongue plate 434. In this embodiment, through the dynamic advancement and retreat of the support bar 432 and the action timing coordination of the folding bottom guide rod 431, the pressing bottom plate 433, and the folding bottom tongue plate 434, and combined with the rigid support provided by the support bar 432 for the pre-folding of the box bottom tongue 1004 at the initial stage of the folding of the bottom cover 1003, the skew of the box bottom tongue 1004 can be effectively avoided, ensuring the reliability of the box bottom closing action, which is beneficial to further improving the box loading efficiency of the turntable type upper-opening box loading machine in this embodiment.

[0032] In another embodiment of the present application, please refer to Figures 1 to 7 as well. The paper box blank 1000 further includes a top cover 1007 connected to the long side 1001, a box top tongue 1008 connected to the top cover 1007, and a front top folding tongue 1009 and a rear top folding tongue 1010 connected to the two short sides 1002. The front bottom folding tongue 1005 and the front top folding tongue 1009 are connected to both ends of the short side 1002 along the height direction of the short side 1002, and the rear bottom folding tongue 1006 and the rear top folding tongue 1010 are connected to both ends of the short side 1002 along the height direction of the short side 1002. The bottom cover 1003 and the top cover 1007 are arranged at both ends of the long side 1001 along the height direction of the long side 1001. The folding box mechanism 400 for closing the paper box after loading is also arranged between the loading mechanism 500 and the discharging conveyor belt 600 along the circumferential direction of the turntable 200 and is used for folding the front top folding tongue 1009 and the rear top folding tongue 1010 to be perpendicular to the short side 1002, for folding the top cover 1007 to be perpendicular to the long side 1001, and for inserting the box top tongue 1008 into the interior of the paper box blank 1000.

[0033] According to the above structure provided in this embodiment, since the positions of the top cover 1007, the top box insert tongue 1008, the front top folding tongue 1009, and the rear top folding tongue 1010 correspond to the positions of the bottom cover 1003, the bottom box insert tongue 1004, the front bottom folding tongue 1005, and the rear bottom folding tongue 1006 respectively, a set of box folding mechanisms 400 additionally provided between the loading mechanism 500 and the discharging conveyor belt 600 along the axial direction of the turntable 200 can correspondingly fold the front top folding tongue 1009 and the rear top folding tongue 1010 to be perpendicular to the short side 1002, and can also fold the top cover 1007 to be perpendicular to the long side 1001 and insert the top box insert tongue 1008 into the interior of the paper box blank 1000. The principle and structure are the same as those of the box folding mechanism 400 for unfolding the paper box blank 1000 into a state capable of top loading, except that the corresponding components are located above the paper box blank 1000, which will not be elaborated here. Through the above structure, the box loading efficiency of the turntable type top-opening box loading machine in this embodiment can be further improved.

[0034] It should be noted that since the front bottom folding tongue 1005 and the front top folding tongue 1009 are connected to both ends of the short side 1002 along the height direction of the short side 1002, the rear bottom folding tongue 1006 and the rear top folding tongue 1010 are connected to both ends of the short side 1002 along the height direction of the short side 1002, and the bottom cover 1003 and the top cover 1007 are arranged at both ends of the long side 1001 along the height direction of the long side 1001, in the actual production process, the box folding mechanism 400 arranged between the magazine 300 and the loading mechanism 500 and the box folding mechanism 400 arranged between the loading mechanism 500 and the discharging conveyor belt 600 should be distributed on both sides of the paper box blank 1000 along the height direction of the paper box blank 1000. In this way, the box folding mechanism 400 arranged between the magazine 300 and the loading mechanism 500 can close the bottom cover 1003 of the paper box blank 1000 to form the paper box blank 1000 into a top-opening loading state, while the box folding mechanism 400 arranged between the loading mechanism 500 and the discharging conveyor belt 600 can close the top cover 1007 of the paper box blank 1000 after loading is completed to achieve the final packaging effect of the product.

[0035] In another embodiment of the present application, please also refer to Figures 1 to 7 , this turntable type top-opening box loading machine further includes a small tongue plate 404 arranged between the magazine 300 and the loading mechanism 500 along the circumferential direction of the turntable 200; the small tongue plate 404 is rotatably installed on the frame 100 and the rotation central axis is perpendicular to the axial direction of the turntable 200, and the rotation path of the small tongue plate 404 also interferes with the movement path of the front top folding tongue 1009 and can drive the geometric center of the front top folding tongue 1009 to move away from the geometric center of the paper box blank 1000 around the axial direction of the turntable 200 during the rotation process.

[0036] According to the above structure provided in this embodiment, through the interference design of the small tongue plate 404 with the axis of the turntable 200 perpendicular to the axial direction of the turntable 200 and the traveling path of the carton blank 1000, when the carton blank 1000 moves with the turntable 200 to between the magazine 300 and the loading mechanism 500, the small tongue plate 404 rotates around the axis and forces the geometric center of the front top folding tongue 1009 to deflect outward around the axis formed by the connection of the front top folding tongue 1009 and the corresponding short side 1002 with its rotation trajectory. In this way, it can avoid the inward folding of the front top folding tongue 1009 and interfere with the loading process of the loading mechanism 500, which is also beneficial to further improve the cartoning efficiency of the turntable type upper cover opening cartoning machine in this embodiment.

[0037] In another embodiment of the present application, please refer to Figures 1 to 7 together. This turntable type upper cover opening cartoning machine further includes a pressing plate 405 arranged circumferentially along the turntable 200 between the loading mechanism 500 and the carton folding mechanism 400 for closing the carton after loading; the pressing plate 405 is movably installed on the frame 100, and the moving direction of the pressing plate 405 is parallel to the axial direction of the turntable 200. The moving path of the pressing plate 405 is also adapted to the moving path of the target material inside the carton blank 1000.

[0038] According to the above structure provided in this embodiment, through the design that the linear moving path of the pressing plate 405 along the axial direction of the turntable 200 is adapted to the moving path of the material inside the carton blank 1000, when the carton blank 1000 rotates with the turntable 200 to the position of the pressing plate 405, the pressing plate 405 can be driven by the driving mechanism to vertically press downward along the axial direction of the turntable 200 and instantaneously compact the target material loaded inside the carton blank 1000, ensuring the stable positioning of the material in the carton and eliminating the risk of difficult insertion of the box top inserting tongue 1008 when the top cover 1007 is closed due to the loose material. This is also beneficial to further improve the cartoning efficiency of the turntable type upper cover opening cartoning machine in this embodiment.

[0039] In another embodiment of the present application, please refer to Figures 1 to 7 together. The turntable type upper cover opening cartoning machine further includes a bottom supporting guide plate 406, and this bottom supporting guide plate 406 is used to support the bottom of the carton formed after the carton blank 1000 is unfolded; the bottom supporting guide plate 406 forms an arc coaxial with the turntable 200 and extends from the loading mechanism 500 to the discharge conveyor belt 600. The front end of the bottom supporting guide plate 406 is also connected to the end of the carton folding bottom guide rod 431.

[0040] According to the above structure provided in this embodiment, through the arc design of the bottom supporting guide plate 406 coaxial with the turntable 200 and the layout arrangement extending from the loading mechanism 500 to the discharging conveyor belt 600, the bottom of the carton blank 1000 can always be in contact with the bottom supporting guide plate 406 during the loading process and subsequent conveying process for sliding support, so as to prevent the bottom cover 1003 from accidentally opening due to uneven force during the loading or transfer process, which is also conducive to further improving the cartoning efficiency of the turntable type top-opening cartoning machine in this embodiment.

[0041] In another embodiment of the present application, please also refer to Figures 1 to 7 , the turntable type top-opening cartoning machine further includes a vertical cover guide plate 407 and a side guard rail 408 coaxially arranged with the bottom supporting guide plate 406. The vertical cover guide plate 407 and the side guard rail 408 are arranged above the bottom supporting guide plate 406 along the radial direction of the bottom supporting guide plate 406; the vertical cover guide plate 407 extends from the position of the small tongue plate 404 to the loading mechanism 500 and is used to abut against the top cover 1007 to limit the top cover 1007 from automatically folding to be perpendicular to the long side 1001 under the action of gravity. The path side guard rail 408 extends from the head to the tail along the carton blank 1000 to the adjacent sides of the storage bin 300 and the discharging conveyor belt 600; the bottom supporting guide plate 406 and the side guard rail 408 are used to conduct sliding guidance on the unfolded carton blank 1000 when the carton clamping seat 700 drives the carton blank 1000 clamped therein to move forward.

[0042] According to the above structure provided in this embodiment, by arranging the vertical cover guide plate 407 coaxial with the bottom supporting guide plate 406 and the side guard rail 408 above the bottom supporting guide plate 406 along the radial direction of the bottom supporting guide plate 406, three-dimensional space limit and movement guidance can be formed for the carton blank 1000, so that the folding carton blank can maintain a stable posture during the rotation process with the turntable 200. In addition, the vertical cover guide plate 407 extending from the position of the small tongue plate 404 to the loading mechanism 500 and continuously abutting against the inner wall of the top cover 1007 in this embodiment can keep the top cover 1007 in an open state all the time before loading, so that the loading process can be carried out efficiently, which is also conducive to further improving the cartoning efficiency of the turntable type top-opening cartoning machine in this embodiment.

[0043] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
