[0002] Paper product packaging is the type with the largest consumption in industrial product packaging. Cartons are the main form of transportation packaging and are widely used in the sales packaging of various products such as food, medicine, and electronics. The production process of cartons usually includes the following steps: First, raw material preparation; second, cardboard production; third, printing; fourth, die-cutting and creasing; fifth, folding, nailing, and flipping.

[0003] In the fifth step of carton production, a carton processing system is mainly used to process the four-sided cardboard after the fourth step. The carton processing system includes a conveying mechanism, a folding mechanism, a nailing mechanism, and a flipping mechanism. Among them, the conveying mechanism is mainly used to transport the cardboard throughout the processing process; the folding mechanism is mainly used to fold the two sides on the upper side of the four-sided cardboard so that the two sides on the side coincide with the two middle sides respectively; the nailing mechanism is mainly used to nail and connect the ends of the two sides on the side; the flipping mechanism is mainly used to flip the folded and nailed carton, move the connecting iron nails of the carton to the side, and enable all four creases of the carton to be folded smoothly. The flipping method is as disclosed in the patent with application number 2018217192638.

[0004] Although the existing carton processing systems can perform good folding, nailing, and flipping operations on the cardboard, they can only process cardboard of fixed sizes and cannot automatically adjust and process cardboard of different specifications, which has certain limitations. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a carton processing system to solve the problem pointed out in the background art that although the existing carton processing systems can perform good folding, nailing, and flipping operations on the cardboard, they can only process cardboard of fixed sizes and cannot automatically adjust and process cardboard of different specifications.

[0006] The present invention solves the above technical problems through the following technical means:

[0007] A carton processing system, characterized by comprising:

[0008] A machine base, on which a control system is installed;

[0009] An infeed conveyor, which is installed on the machine base and is used for feeding the four-sided cardboard;

[0010] An outfeed conveyor, which is installed on the machine base and is used for discharging the carton products;

The intermediate conveying mechanism includes an electric slide rail and two groups of processing conveyors. The two groups of processing conveyors are respectively arranged on both sides of the machine base, and the processing conveyors are movably installed on the machine base along the width direction of the machine base through the electric slide rail;

[0038] The fourth driving cylinder is mounted on the machine base and is used to drive the lifting seat to move.

[0039] Advantages of the present application:

[0040] 1. By setting up structures such as a machine base, a feeding conveyor, a discharging conveyor, an intermediate conveying mechanism, two sets of folding mechanisms, an identification mechanism, etc., when the four-sided cardboard is fed, the identification mechanism can obtain the size data of the four-sided cardboard. The control system then analyzes based on the size data and the pre-stored template data, and then controls the intermediate conveying mechanism to adjust to a state suitable for the cardboard size through the control system, so that the processing system can automatically adapt to different specifications of cardboard, thereby expanding the applicable range of the processing system.

[0041] 2. By setting up structures such as an electric slide rail, two sets of processing conveyors, and a bearing strip board, the two sets of processing conveyors and the bearing strip board cooperate with each other to realize the whole-process transportation of the cardboard, enabling the cardboard to reach each processing procedure smoothly; the two sets of processing conveyors can adjust their positions through the electric slide rail, enabling the intermediate conveying mechanism to process cardboard of different size specifications, with a wide applicable range.

[0042] 3. By setting up structures such as a pressure strip, a flipping plate, and a folding guiding component, when the four-sided cardboard is transported to the folding mechanism, it will first pass through the pressure strip and the flipping plate. The pressure strip plays a limiting role in the vertical direction for the four-sided cardboard, and then the flipping plate is driven to rotate by the second motor, causing the side surface of the four-sided cardboard to be folded by 90 degrees; then through the subsequent folding guiding component, the side surface of the four-sided cardboard is folded by 90 degrees again, enabling the folding operation of the two sides of the side of the four-sided cardboard, making the two side surfaces coincide with the two middle surfaces respectively; thus realizing the folding operation of the cardboard.

[0043] 4. By setting up structures such as a gantry, a connecting seat, a stapling machine body, and a blocking plate, when the cardboard after the folding operation is transported to the stapling mechanism, first the blocking plate is driven to rotate by the third motor, causing the blocking plate to block the moving cardboard; then the connecting seat is driven to move downward by the first driving cylinder, causing the stapling machine body to contact the cardboard; then the stapling machine body performs a stapling operation on the cardboard, stapling and connecting the ends of the two upper side surfaces of the four-sided cardboard; finally, the blocking plate and the connecting seat are controlled to reset, enabling the cardboard to be transported to the next process.

[0044] 5. In this application, by setting structures such as an auxiliary fixing component and a flipping driving component, when the cardboard is transported to the flipping mechanism after folding and nailing operations are completed, the vacuum pump is first started, and one surface of the cardboard is adsorbed and fixed through the vacuum suction plate. Then, the second driving cylinder drives the third driving cylinder and the driving plate to move upward. During this process, the third driving cylinder controls the driving plate to move towards the side close to the auxiliary fixing component, so that the driving plate can cross the bearing strip plate, thereby enabling the cardboard to flip along a trajectory similar to a parallelogram. When the output shaft strokes of the second driving cylinder and the third driving cylinder reach the preset strokes, the second driving cylinder drives the third driving cylinder and the driving plate to move downward. During this process, the driving plate that has crossed the bearing strip plate can perform a downward pressing operation on the arched cardboard, thereby assisting the cardboard to complete the subsequent flipping operation. When the output shaft of the second driving cylinder is about to reset, the second driving cylinder temporarily works, and then the third driving cylinder is controlled to reset. When the third driving cylinder is fully reset, the second driving cylinder is started again to complete the reset operation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0056] As Figures 1-9 As shown, the embodiment of the present application provides a carton processing system, including a machine base 100, a feeding conveyor 200, a discharging conveyor 300, an intermediate conveying mechanism, two folding mechanisms, an identification mechanism 600, a nailing mechanism and a flipping mechanism. Among them, the machine base 100 is used to install each mechanism, and a control system is installed on the machine base 100 for automatic control of each electrical component in the processing system; the feeding conveyor 200 is installed at the head end of the machine base 100 for the feeding process of the four-sided cardboard; the discharging conveyor 300 is installed at the tail end of the machine base 100 for the discharging of the carton products; the identification mechanism 600 is installed on the upper side of the feeding conveyor 200 for identifying the size of the four-sided cardboard and transmitting the size data to the control system; the intermediate conveying mechanism is installed between the feeding conveyor 200 and the discharging conveyor 300 for the transportation work during the processing of the four-sided cardboard; the folding mechanism, the nailing mechanism and the flipping mechanism are sequentially arranged along the conveying direction of the intermediate conveying mechanism. The folding mechanism is used for the folding operation of the four-sided cardboard, the nailing mechanism is used for the connection operation of the folded cardboard, and the flipping mechanism is used for the flipping operation of the carton products.

[0057] In this embodiment, the feeding conveyor 200 and the discharging conveyor 300 are both ordinary belt conveyors, and their specific structures will not be elaborated in detail. In addition, a flattening mechanism is provided at the tail of the feeding conveyor 200. The flattening mechanism is mainly used to flatten the four-sided cardboard so that the four-sided cardboard can enter the intermediate conveying mechanism smoothly and orderly. The structure of the flattening mechanism is prior art and will not be elaborated in this embodiment.

[0058] In this embodiment, the intermediate conveying mechanism is installed between the feeding conveyor 200 and the discharging conveyor 300. Specifically, the intermediate conveying mechanism includes an electric slide rail 410, two groups of processing conveyors 420, and a bearing strip 430. The two groups of processing conveyors 420 are respectively arranged on both sides in the width direction of the machine base 100. When conveying the cardboard, both groups of processing conveyors 420 can carry part of the area of the cardboard. In order to adapt to different specifications of cardboard, the processing conveyor 420 is movably installed on the machine base 100 along the width direction of the machine base 100 through the electric slide rail 410.

[0059] Specifically, the processing conveyor 420 includes a mounting frame 421, a conveyor belt 422, and a plurality of belt pulleys 423. A sliding seat is installed on the bottom side of the mounting frame 421, and the sliding seat is installed on the electric slide rail 410. In addition, since the processing conveyor 420 is relatively long, the number of electric slide rails 410 can be set to multiple, which is convenient for the installation of the processing conveyor 420. All the belt pulleys 423 are rotatably installed on the mounting frame 421, and a first motor for driving the belt pulleys 423 to rotate is installed on the mounting frame 421. The conveyor belt 422 is installed on a plurality of belt pulleys 423, and the conveyor belt 422 is driven to move by the belt pulleys 423.

[0060] The bearing strip 430 is fixed to the machine base 100 through a plurality of columns 431. The bearing strip is arranged at the middle position between the two groups of processing conveyors 420 and is parallel to the length direction of the processing conveyor 420. The bearing strip 430 can carry the middle part of the cardboard so that the cardboard can move smoothly and steadily.

[0061] The processing conveyor 420 further includes a bearing rod 424. The bearing rod 424 is fixed to the mounting frame 421. The bearing rod 424 can carry the side of the cardboard, and its function is the same as that of the bearing strip 430. In addition, the bearing rod 424 is arranged on the front side of the folding mechanism. It can be understood that when the four-sided cardboard is not folded, the bearing rod 424 can assist in carrying the two sides of the side of the four-sided cardboard; after the four-sided cardboard is folded, the two sides of the side of the four-sided cardboard are folded over, and the assistance of the bearing rod 424 is no longer required.

[0062] In this embodiment, the recognition mechanism 600 includes a connecting frame 610, an industrial camera 620, and a processor. The connecting frame 610 is installed on the feeding conveyor 200, and the industrial camera 620 is installed on the connecting frame 610. When the four-sided cardboard passes through the feeding conveyor 200, the industrial camera 620 can obtain the image data of the four-sided cardboard, and then the processor calculates the size data of the four-sided cardboard based on the image data; then the size data of the four-sided cardboard is transmitted to the control system, and the control system analyzes according to the size data and the pre-stored template data, and then controls the electric slide rail 410 to work, adjusting the positions of the two groups of processing conveyors 420 in the width direction of the machine base 100 to adapt to different specifications of cardboard.

[0063] In another embodiment, the industrial camera 620 can also be replaced by an ordinary camera, which can also collect image data.

[0064] It should be noted that, as Figure 9 shown, there are three main creases and one connecting edge crease on the four-sided cardboard. Among them, the three main creases can divide the four-sided cardboard into four sides, and the connecting edge crease is mainly set at the position where nails need to be driven at the end of the four-sided cardboard. When the four-sided cardboard is folded, the main creases on both sides must be outside the processing conveyor 420 to be successfully folded by the folding mechanism. It can also be understood that the two middle sides of the four-sided cardboard need to be between the two processing conveyors 420, and the two side sides need to be outside the two processing conveyors 420 for the four-sided cardboard to be successfully folded. Therefore, by adopting the above technical solution, the position of the processing conveyor 420 can be automatically adjusted according to the size of the four-sided cardboard, so that the main creases on both sides of the four-sided cardboard can be located outside the processing conveyor 420, thereby realizing the processing of different specifications of cardboard and improving the applicable range of the device.

[0065] In this embodiment, the two groups of folding mechanisms are respectively installed on the two groups of processing conveyors 420. The folding mechanism includes a pressing strip 510, a turning plate 520, and a folding guiding component 530. Among them, the pressing strip 510 is a long strip structure, the pressing strip 510 is arranged on the upper side of the conveyor belt 422, and there is a gap for the four-sided cardboard to pass between the pressing strip 510 and the conveyor belt 422. The pressing strip 510 is fixed on the mounting frame 421 through a bracket 511. The turning plate 520 is installed at the position corresponding to the pressing strip 510. One end of the turning plate 520 is hinged to the mounting frame 421, and a second motor for driving the turning plate 520 to rotate is installed on the mounting frame 421. The folding guiding component 530 is arranged on the mounting frame 421 along the length direction of the mounting frame 421. The folding guiding component 530 includes a plurality of guiding plates 531 and guiding rods 532, and its main function is to assist the four-sided cardboard to achieve folding.

[0066] When the four-sided cardboard is transported to the folding mechanism, it first passes through the pressing strip 510 and the flipping plate 520. The pressing strip 510 plays a role in limiting the four-sided cardboard in the vertical direction. Then, the flipping plate 520 is driven by the second motor to rotate, so that the side surface of the four-sided cardboard is folded by 90 degrees. Then, through the subsequent folding guiding component 530, the side surface of the four-sided cardboard is folded by 90 degrees again, and the folding operation of the two sides of the side of the four-sided cardboard can be realized, so that the two sides of the side coincide with the two middle faces respectively.

[0067] It should be noted that the design and position arrangement of structures such as the guiding plate 531 and the guiding rod 532 in the folding guiding component 530 can be designed according to specific situations, and this embodiment does not make specific limitations, as long as the folding operation can be realized. In another embodiment, the folding guiding component can also adopt a belt with a specific structure arrangement, which can also realize the folding operation of the cardboard.

[0068] In another embodiment, the flipping plate 520 in the folding mechanism can also be replaced by structures such as a flipping rod and a flipping strip, which can also realize the folding operation of the cardboard.

[0069] In this embodiment, the nailing mechanism is arranged at the rear side of the folding mechanism. The nailing mechanism includes a gantry 710, a connecting seat 720, a nailing machine body 730, and a blocking plate 750. Among them, the gantry 710 is fixed on the machine base 100 and straddles the middle conveying mechanism. The connecting seat 720 is arranged on the upper side of the middle conveying mechanism and is movably installed on the gantry 710 in the vertical direction. A first driving cylinder 760 for driving the connecting seat 720 to move is installed on the gantry 710; the nailing machine body 730 is fixed on the connecting seat 720 and is located directly above the placing strip 430. One end of the blocking plate 750 is hinged on the gantry 710 and is used to block the transmission of the cardboard on the middle conveying mechanism. A third motor for driving the blocking plate 750 to rotate is installed on the gantry 710.

[0070] When the cardboard that has completed the folding operation is transported to the nailing mechanism, first, the third motor drives the blocking plate 750 to rotate, so that the blocking plate 750 blocks the moving cardboard; then, the first driving cylinder 760 drives the connecting seat 720 to move downward, so that the nailing machine body 730 contacts the cardboard; then, the nailing machine body 730 performs a nailing operation on the cardboard to nail and connect the ends of the two upper side faces of the four-sided cardboard; finally, the blocking plate 750 and the connecting seat 720 are controlled to reset, so that the cardboard is transported to the next process.

[0071] In this embodiment, the flipping mechanism is arranged at the rear side of the nailing mechanism. The flipping mechanism includes an auxiliary fixing component 810 and a flipping driving component 820. Among them, both the auxiliary fixing component 810 and the flipping driving component 820 are arranged between two groups of processing conveyors 420 and are respectively located on both sides of the bearing strip plate 430; the auxiliary fixing component 810 is used to fix one surface of the cardboard, and the flipping driving component 820 is used to drive the flipping of the other surface of the cardboard. It can be understood that when the four-sided cardboard completes the folding and nailing operations, the flipping operation of the four-sided cardboard itself is similar to the movement of a parallelogram. By fixing one surface of the cardboard through the auxiliary fixing component 810 and then driving the flipping of the other surface through the flipping driving component 820, the flipping operation of the cardboard can be driven to be completed.

[0072] In this embodiment, the auxiliary fixing component 810 includes a vacuum suction plate 811 and a vacuum pump 812. Among them, the adsorption surface of the vacuum suction plate 811 faces upward and is parallel to the upper surface of the conveyor belt 422; the vacuum pump 812 is connected to the vacuum suction plate 811 through a hose to provide negative pressure suction for the vacuum suction plate 811.

[0073] In this embodiment, the flipping driving component 820 includes a second driving cylinder 821, a third driving cylinder 822 and a driving plate 823. Among them, the second driving cylinder 821 is arranged in the vertical direction; the third driving cylinder 822 is arranged in the width direction of the machine base 100, the third driving cylinder 822 is fixed on the output shaft of the second driving cylinder 821, and the output shaft of the third driving cylinder 822 faces the side of the auxiliary fixing component 810; the driving plate 823 is fixed on the output shaft of the third driving cylinder 822, and the upper surface of the driving plate 823 is parallel to the upper surface of the conveyor belt 422.

[0074] When the cardboard is transported to the flipping mechanism after completing the folding and nailing operations, first start the vacuum pump 812 to adsorb and fix one surface of the cardboard through the vacuum suction plate 811; then drive the third driving cylinder 822 and the driving plate 823 to move upward through the second driving cylinder 821. During this process, control the driving plate 823 to move toward the side close to the auxiliary fixing component 810 through the third driving cylinder 822, so that the driving plate 823 can cross over the bearing strip plate 430, thereby enabling the cardboard to flip along a trajectory similar to a parallelogram; when the output shaft strokes of the second driving cylinder 821 and the third driving cylinder 822 reach the preset strokes, then drive the third driving cylinder 822 and the driving plate 823 to move downward through the second driving cylinder 821. During this process, the driving plate 823 that has crossed over the bearing strip plate 430 can perform an operation of pressing down on the arched cardboard, thereby assisting the cardboard to complete the subsequent flipping operation; when the output shaft of the second driving cylinder 821 is about to reset, temporarily stop the operation of the second driving cylinder 821, and then control the third driving cylinder 822 to reset; when the third driving cylinder 822 is completely reset, then start the second driving cylinder 821 to complete the reset operation.

[0075] It should be noted that the strokes of the output shafts of the second driving cylinder 821 and the third driving cylinder 822 are also calibrated according to the size of the cardboard and are automatically set by the control system.

[0076] In another embodiment, the auxiliary fixing assembly 810 may also adopt a structure similar to a clamp to clamp and fix the front and rear ends of one side of the four-sided cardboard, and can also achieve the fixation of one side of the four-sided cardboard.

[0077] In another embodiment, the flipping drive assembly 820 may also be set as a structure such as a drive rod. One end of the drive rod is hinged to the machine base, and a motor for controlling the rotation of the drive rod is installed on the machine base. When the drive rod rotates, it can also drive the cardboard to flip, but the achieved effect is relatively poor.

[0078] In this embodiment, the flipping mechanism further includes a lifting seat 830 and a fourth driving cylinder 840. Among them, the lifting seat 830 is movably installed on the machine base 100 in the vertical direction, and the vacuum suction plate 811 and the second driving cylinder 821 are both fixed on the lifting seat 830; the fourth driving cylinder 840 is installed on the machine base 100 and is used to drive the lifting seat 830 to move. By such a setting, when the cardboard is transported to the flipping mechanism after folding and nailing operations, first, the fourth driving cylinder 840 drives the lifting seat 830 to move upward by a certain distance, for example, 5 cm, so that the vacuum suction plate 811 and the drive plate 823 rise, and the cardboard is lifted upward, so that the cardboard can be temporarily separated from the transportation of the processing conveyor 420, and then the adsorption fixation and flipping operations of the cardboard are carried out. Such a design is more conducive to realizing the flipping operation of the cardboard.

[0079] In this embodiment, the flipping mechanism further includes an auxiliary conveyor 850. The auxiliary conveyor 850 is installed on the mounting frame 421 close to the side of the vacuum suction plate 811, and the auxiliary conveyor 850 is an ordinary belt conveyor. It can be understood that when the cardboard is flipped, one side of the cardboard may be in a suspended state due to insufficient support, affecting the transmission of the cardboard. By designing the auxiliary conveyor 850, it can play a role in supporting and transporting the folded cardboard, so that the folded cardboard can be smoothly transported to the discharge conveyor 300.

[0080] In another embodiment, the flipping mechanism may also adopt the structure disclosed in the patent with the application number 2018217192638, and can also perform the flipping operation of the cardboard.

[0081] It should be noted that the motors used in this embodiment can be servo motors or stepper motors, and the driving cylinders used in this embodiment can be electric cylinders, air cylinders or oil cylinders.
