Description

Technical Field

[0001] The present invention belongs to the technical field of paper box production, and specifically relates to a grasping device for the production of packaging paper boxes. Background Art

[0002] The production of packaging paper boxes is a process of processing paper or cardboard into various gift box types through processes such as printing, die-cutting, gluing, punching, packaging, and labeling, and is widely used in industries such as food, electronics, and cosmetics.

[0003] During the production of packaging paper boxes, it is necessary to continuously grasp the packaging paper boxes for process operations such as design, printing, die-cutting, labeling, box gluing, quality inspection, and packaging. The grasping of packaging paper boxes is usually carried out by production robots instead of manual labor. The robots rely on the writing of programs to control and can accurately and quickly grasp the paper boxes.

[0004] In the existing packaging paper box production line, robots are often used to assist in grasping packaging paper boxes to complete the labeling work. In traditional practices, a single robot usually independently grasps a single packaging paper box to a designated station for labeling. Although this single grasping method simplifies the operation, it has low efficiency and is difficult to meet the high-efficiency requirements of large-scale production. In addition, if multiple packaging paper boxes need to be processed at the same time, multiple robots are usually used to work together. Each robot needs to write a corresponding control program and may require additional control accessories for synchronization, increasing the complexity of the equipment and the maintenance cost. Even more complex is that the synchronous programming and control of multiple robots increase the debugging difficulty of the system, and the running tracks and control logics of each robot make the coordination of the overall system more difficult.

[0028] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation mode.

[0029] Such as Figures 1 to 6As shown in the figure, the grasping device for the production of packaging cartons according to the embodiment of the present invention includes a machine base 1; a machine frame 11 is fixedly connected to the top end of the machine base 1; a first electric slider 12 is slidably connected to the inner wall of the bottom of the machine frame 11; a cylinder 13 is fixedly connected to the bottom end of the first electric slider 12; a fixed frame 14 is fixedly connected to the bottom end of the cylinder 13; a sliding plate 15 is slidably connected to the inner wall of the fixed frame 14 through a second electric slider; a mating plate 16 is fixedly connected to the side of the sliding plate 15 away from the fixed frame 14; a pushing assembly is arranged inside the machine base 1, and the pushing assembly is used to push the packaging cartons to the grasping position; when grasping and labeling a large number of packaging cartons during production, the machine base 1 is used as the main support of the manipulator grasping device. First, the control program for grasping is written into the manipulator grasping device. Then, multiple cartons are pushed into the inside of the machine base 1. Relying on the pushing assembly, the multiple packaging cartons are sent to the discharge port of the machine base 1. The program controls the first electric slider 12 to drive the fixed frame 14 at the bottom end of the cylinder 13 to slide to the discharge port synchronously. Protective plates can be installed on both sides of the first electric slider 12 to protect it. The mating plate 16 connected to the sliding plate 15 slides synchronously with the fixed frame 14. At this time, multiple packaging cartons are neatly attached and arranged at the discharge port of the machine base 1. The program controls the second electric slider to drive the sliding plate 15 to slide on the fixed frame 14. The mating plate 16 cooperates with the fixed frame 14 to clamp and grasp the multiple neatly arranged packaging cartons, and synchronously grabs the multiple packaging cartons to the labeling station for labeling work. After a batch of packaging cartons is labeled, it immediately returns to the discharge port of the machine base 1 to grab the next batch of cartons, replacing the traditional grasping method of the manipulator, reducing the writing of the manipulator control program, lowering the equipment complexity, maintenance cost, and the debugging difficulty of synchronous control. At the same time, by controlling the second electric slider to drive the mating plate 16, it can freely slide close to the fixed frame 14, so as to facilitate the control of the change in the number of grasped packaging cartons. When a small number of cartons need to be grasped, the second electric slider drives the mating plate 16 close to the fixed frame 14. When a large number of cartons need to be grasped, the second electric slider drives the mating plate 16 away from the fixed frame 14, playing a role in controlling the number of grasped packaging cartons.

[0030] As Figures 1 to 3As shown in the figure, the pushing component includes a loading plate 2, a first cylinder 21, a first air pipe 22, a fixed seat 23, a second cylinder 24 and a pushing plate 25; the loading plate 2 is fixedly connected to the feeding port on the outer wall of the machine base 1; the first cylinder 21 is fixedly connected to the inner wall of the frame 11; the first air pipe 22 is fixedly connected to the first cylinder 21; the fixed seat 23 is fixedly connected to the outer wall of the machine base 1; the second cylinder 24 is fixedly connected to the fixed seat 23, and the second cylinder 24 can be connected to the first cylinder 21 through the first air pipe 22, and the output end of the second cylinder 24 is located inside the machine base 1; the pushing plate 25 is fixedly connected to the output end of the second cylinder 24; when arranging and pushing multiple packaging cartons, rely on the loading manipulator to push multiple packaging cartons into the machine base 1 from the loading plate 2 in sequence, arrange multiple packaging cartons neatly, then the first electric slider 12 slides close to the first cylinder 21 and squeezes and contracts the first cylinder 21, the gas inside the first cylinder 21 is introduced into the second cylinder 24 fixed on the fixed seat 23 through the first air pipe 22, and the first cylinder 21 can reset itself after losing the squeezing force of the first electric slider 12, then the output end of the second cylinder 24 drives the pushing plate 25 to push the sorted multiple packaging cartons to the discharge port of the machine base 1, and the program controls the second electric slider to then drive the matching plate 16 to cooperate with the fixing frame 14 to clamp and grab multiple packaging cartons and send them to the labeling station for labeling, playing a role in synchronously pushing multiple packaging cartons.

[0031] As Figure 1 and Figure 2 shown in the figure, a connecting plate 31 is fixedly connected to the bottom end of the pushing plate 25, and a plurality of threaded holes are formed in the connecting plate 31; a limiting plate 3 is arranged on the connecting plate 31; a bolt 32 is commonly threadedly connected to the limiting plate 3 and the connecting plate 31; when loading and pushing multiple packaging cartons, rely on the bolt 32 to threadedly fix the limiting plate 3 on the connecting plate 31, then push multiple packaging cartons into the space between the pushing plate 25 and the limiting plate 3 in sequence for temporary storage, which is convenient for neatly arranging multiple packaging cartons. After the arrangement is completed, the pushing plate 25 pushes multiple packaging cartons to the discharge port for grasping. The neatly arranged multiple packaging cartons can improve the stability of grasping. At the same time, when grasping different models of packaging cartons, according to the different shapes of the packaging cartons, the limiting plate 3 is correspondingly fixed on the threaded holes formed in the connecting plate 31 through the bolt 32, which can adapt to the grasping of different models of packaging cartons and improve the adaptability of grasping packaging cartons.

[0032] A guide block 4 is fixedly connected to the inner wall of the base 1 near the feed inlet, and the side of the guide block 4 close to the loading plate 2 is provided with a slope; the inner wall of the base 1 opposite to the guide block 4 is provided with an arc; when loading multiple packaging cartons, the guide block 4 is fixed on one side of the limit plate 3 and is located at the feed inlet of the base 1. The slope wall of the guide block 4 can cooperate with the arc wall of the base 1 to guide the pushed and arranged packaging cartons, so that the packaging cartons can be guided into the interior of the base 1 and neatly arranged between the second cylinder 24 and the limit plate 3 waiting to be pushed, improving the loading effect of multiple packaging cartons.

[0033] As Figure 1 、 Figures 3 to 6 shown, a third cylinder 5 is fixedly connected to the sliding plate 15 and the mating plate 16 together; the output end of the third cylinder 5 is fixedly connected with a fixing plate 51; the bottom end of the fixing plate 51 is fixedly connected with a connecting seat 52; the inner walls of both sides of the connecting seat 52 are slidably connected with inner lining plates 53; an elastic member 54 is fixedly connected between the inner lining plate 53 and the inner wall of the connecting seat 52; a transmission mechanism is arranged on the frame 11, and the transmission mechanism is used to control the telescopic movement of the inner lining plate 53; when grasping a packaging carton with an open end, since some workstations are far from the discharge port of the base 1, the carton is likely to fall off during the grasping and feeding process. When grasping and feeding for a relatively close coding workstation, the method of clamping with the mating plate 16 and the fixing frame 14 is still used for short-distance grasping and feeding. When grasping and feeding for a relatively far coding workstation, while using the mating plate 16 to cooperate with the fixing frame 14 to clamp, the program controls the first electric slider 12 to slide and trigger the transmission mechanism. The transmission mechanism sends gas into the third cylinder 5 and the fixing plate 51 communicated with the third cylinder 5. At this time, the output end of the third cylinder 5 extends downward, and the third cylinder 5 drives a plurality of connecting seats 52 connected to the bottom end of the fixing plate 51 to synchronously extend into the interior of the packaging carton. Then, gas is introduced into the plurality of connecting seats 52, and the gas pushes the inner lining plates 53 on both sides in the connecting seats 52 to slide out. The elastic member 54 is stretched and stressed. At this time, the two inner lining plates 53 squeeze the inner wall of the packaging carton in the opposite direction. The inner lining plate 53 close to the mating plate 16 squeezes one side of the packaging carton to fit on the mating plate 16, and the inner lining plate 53 on the other side and the adjacent inner lining plate 53 on another connecting seat 52 clamp the two walls of the two cartons synchronously, realizing the function of tightly clamping the open end of the packaging carton and improving the stability of long-distance grasping and feeding of the packaging carton with an open end.

[0034] The transmission mechanism includes a fourth cylinder 6, a gas guide plate 61, a second air pipe 62, a shunt box 63, a connecting pipe 64 and a matching component; the fourth cylinder 6 is fixedly connected to the inner wall of the frame 11, and the fourth cylinder 6 is arranged opposite to the first cylinder 21; the gas guide plate 61 is fixedly connected to the fourth cylinder 6; the second air pipe 62 is fixedly connected to the gas guide plate 61; the shunt box 63 is fixedly connected to the third cylinder 5, and the third cylinder 5 can be connected to the fourth cylinder 6 through the shunt box 63, the second air pipe 62 and the gas guide plate 61; the connecting pipe 64 is fixedly connected to the third cylinder 5 and the fixed plate 51, and the third cylinder 5 can be connected to the fixed plate 51 through the connecting pipe 64; the matching component is arranged on the shunt box 63 and is used to assist in controlling the gas flow at the shunt box 63; when controlling the sliding of multiple inner liners 53, the output end of the fourth cylinder 6 is retracted by sliding the first electric slider 12. After the fourth cylinder 6 loses the extrusion force of the first electric slider 12, it can reset itself. The gas inside the fourth cylinder 6 is sent into the second air pipe 62 through the gas guide plate 61. Half of the pipe of the second air pipe 62 is made of a rigid material, and the other half is made of a soft material. The gas enters the shunt box 63 for diversion, and the gas flow inside the shunt box 63 is controlled by the matching component written into the program. Most of the gas first enters the inside of the third cylinder 5 to make its output end extend, and multiple connecting seats 52 slide into the inside of multiple packaging cartons. Subsequently, part of the gas enters the fixed plate 51 through the diversion of the connecting pipe 64, and then the gas enters multiple connecting seats 52. The gas squeezes multiple inner liners 53 to extend and clamp and support both sides of the packaging carton. When the first electric slider 12 continues to slide, it will squeeze out the excess gas. On the premise of ensuring the support and clamping at multiple connecting seats 52, the excess gas is discharged externally by the matching component, thereby improving the effect of remotely grasping and feeding multiple packaging cartons.

[0035] The matching component includes a first solenoid valve 7 and a second solenoid valve 71; the first solenoid valve 7 is fixedly connected to the inside of the shunt box 63 and is located at the position of the third cylinder 5; the second solenoid valve 71 is fixedly connected to one side of the shunt box 63; when the gas in the fourth cylinder 6 is squeezed by the first electric slider 12 and sent into the shunt box 63, at this time, the program controls the second solenoid valve 71 to be in a closed state and the first solenoid valve 7 to be in an open state. A large amount of gas is introduced into the inside of the third cylinder 5 to drive the fixed plate 51 to slide down and multiple inner liners 53 to extend. When the first electric slider 12 continues to slide and squeeze, excess gas will be generated. Subsequently, the program controls the first solenoid valve 7 to close and the second solenoid valve 71 to open, and the excess gas is discharged from the second solenoid valve 71. When multiple packaging cartons are remotely sent to the working station, the first solenoid valve 7 is opened to release air, and the elastic member 54 pulls the inner liner 53 to reset, and the packaging carton is lowered, playing a role in controlling the gas flow at the shunt box 63.

[0036] One end of the inner lining plate 53 away from the elastic member 54 is fixedly connected with a pressing plate 8; the cross-sectional shape of the pressing plate 8 is trapezoidal; when a plurality of inner lining plates 53 slide out of the inside of the connecting seat 52, the pressing plate 8 with a trapezoidal surface synchronously presses the outer wall of the packaging paper box, and by increasing the contact area with the packaging paper box, the stability of grasping and supporting the packaging paper box is improved.

[0037] As Figure 1 , Figure 4 and Figure 5 shown, friction pads 9 are fixedly connected to both the fixing frame 14 and the mating plate 16, and the two friction pads 9 are arranged oppositely; a plurality of anti-slip bumps are fixedly connected to the friction pads 9; when clamping and grasping a plurality of packaging paper boxes, the two friction pads 9 are respectively fixed on the mating plate 16 and the fixing frame 14 to fit the outer walls of the two packaging paper boxes, and cooperate with a plurality of anti-slip bumps to increase friction and reduce the occurrence of the situation where the plurality of packaging paper boxes fall off during the grasping process.

[0038] As Figure 1 , Figures 3 to 5 shown, a through groove 91 is formed in the fixing frame 14, and the through groove 91 is located at a position close to the connecting seat 52; when a plurality of connecting seats 52 are installed below the sliding plate 15, the through groove 91 formed in the fixing frame 14 facilitates the displacement of the plurality of connecting seats 52, so that when the second electric slider drives the sliding plate 15 to slide and adjust the amount of grasped packaging paper boxes, it is not limited by the installation of the connecting seats 52, and the connecting seats 52 can slide through the through groove 91 when adjusting the grasping amount of the packaging paper boxes, improving the adaptability of the grasping device to adjust the grasping amount.

[0039] Working process: When grasping and applying codes to large-scale packaging cartons, the machine base 1 serves as the main support for the grasping device. First, write the control program for grasping into the grasping device. Push multiple cartons into the interior of the machine base 1, and rely on the pushing component to send multiple packaging cartons to the discharge port of the machine base 1. The program controls the first electric slider 12 to synchronously drive the fixed frame 14 at the bottom of the electric cylinder 13 to slide to the discharge port. The mating plate 16 connected to the sliding plate 15 slides synchronously with the fixed frame 14. At this time, multiple packaging cartons are neatly attached and arranged side by side at the discharge port of the machine base 1. The program controls the second electric slider to then drive the sliding plate 15 to slide on the fixed frame 14. The mating plate 16 cooperates with the fixed frame 14 to clamp and grasp multiple neatly arranged packaging cartons, and synchronously grasp multiple packaging cartons to the code application station for code application work. After a batch of packaging cartons is coded, immediately return to the discharge port of the machine base 1 to grasp the next batch of cartons, replacing the traditional grasping method of the manipulator, reducing the writing of the manipulator control program, and reducing the equipment complexity, maintenance cost, and debugging difficulty of synchronous control. At the same time, through the program control, the second electric slider drives the mating plate 16 to be able to freely slide close to the fixed frame 14, thereby facilitating the control of the change in the number of grasped packaging cartons. When a small number of cartons need to be grasped, the second electric slider drives the mating plate 16 to approach the fixed frame 14. When a large number of cartons need to be grasped, the second electric slider drives the mating plate 16 to move away from the fixed frame 14, playing a role in controlling the number of grasped packaging cartons; when pushing and arranging multiple packaging cartons, multiple packaging cartons are sequentially pushed into the interior of the machine base 1 from the feeding plate 2, and multiple packaging cartons are neatly arranged. Subsequently, the first electric slider 12 slides close to the first cylinder 21 and squeezes and contracts the first cylinder 21. The gas inside the first cylinder 21 is introduced into the second cylinder 24 fixed on the fixed seat 23 through the first air pipe 22. After the first cylinder 21 loses the squeezing force of the first electric slider 12, it can reset itself. Subsequently, the output end of the second cylinder 24 drives the push plate 25 to push the sorted multiple packaging cartons to the discharge port of the machine base 1. The program controls the second electric slider to then drive the mating plate 16 to cooperate with the fixed frame 14 to clamp and grasp multiple packaging cartons and send them to the code application station for code application, playing a role in synchronously pushing multiple packaging cartons; when feeding and pushing multiple packaging cartons, rely on the bolt 32 to threadedly fix the limiting plate 3 on the connecting plate 31. Subsequently, push multiple packaging cartons in sequence between the push plate 25 and the limiting plate 3 for temporary storage, facilitating the neat arrangement of multiple packaging cartons. After the arrangement is completed, the push plate 25 pushes multiple packaging cartons to the discharge port for grasping. The neatly arranged multiple packaging cartons can improve the stability of grasping. At the same time, when grasping different models of packaging cartons, according to the different shapes of the packaging cartons through the bolt 32, fix the limiting plate 3 on the threaded holes opened on the connecting plate 31 correspondingly, which can adapt to the grasping of different models of packaging cartons and improve the adaptability of grasping packaging cartons;

[0040] When loading multiple packaging cartons, the guiding block 4 is fixed to one side of the limiting plate 3 and is located at the feeding port of the machine base 1. The ramp wall of the guiding block 4 can cooperate with the arc wall of the machine base 1 to guide the pushed and arranged packaging cartons, so that the packaging cartons can be guided into the interior of the machine base 1 and neatly arranged between the second cylinder 24 and the limiting plate 3 to wait for pushing, improving the feeding effect of multiple packaging cartons;

[0041] When grasping the end-opening packaging paper box, since some workstations are far from the discharge port of the machine base 1, the paper box is likely to fall off during the grasping and feeding process. When grasping and feeding for the relatively close labeling workstation, the short-distance grasping and feeding is still carried out by the method of clamping with the matching plate 16 and the fixing frame 14. When grasping and feeding for the relatively far labeling workstation, while using the matching plate 16 to cooperate with the fixing frame 14 for clamping, the program controls the first electric slider 12 to slide and trigger the transmission mechanism. The transmission mechanism sends gas into the third cylinder 5 and the inside of the fixing plate 51 connected to the third cylinder 5. At this time, the output end of the third cylinder 5 extends downward, and the third cylinder 5 drives a plurality of connecting seats 52 connected to the bottom end of the fixing plate 51 to synchronously extend into the inside of the packaging paper box. Subsequently, gas is introduced into the plurality of connecting seats 52, and the gas pushes the inner lining plates 53 on both sides in the connecting seats 52 to slide out, and the elastic members 54 are stretched and stressed. At this time, the two inner lining plates 53 squeeze the inner wall of the packaging paper box in the opposite direction. The inner lining plate 53 close to the matching plate 16 squeezes one side of the packaging paper box to fit on the matching plate 16, and the inner lining plate 53 on the other side and the inner lining plate 53 close to it on another connecting seat 52 synchronously clamp the two walls of the two paper boxes, realizing the function of tightly clamping the end opening of the packaging paper box and improving the stability of the long-distance grasping and feeding of the end-opening paper box; when controlling the sliding of the plurality of inner lining plates 53, the first electric slider 12 is used to slide and push the output end of the fourth cylinder 6 to retract. After the fourth cylinder 6 loses the extrusion force of the first electric slider 12, it can reset itself. The gas inside the fourth cylinder 6 is sent into the second air pipe 62 through the air guide plate 61. Half of the pipe of the second air pipe 62 is made of hard material, and the other half is made of soft material. The gas enters the flow dividing box 63 for diversion, and the gas flow in the flow dividing box 63 is controlled by the matching components written in the program. Most of the gas first enters the inside of the third cylinder 5 to make its output end extend, and a plurality of connecting seats 52 slide into the inside of a plurality of packaging paper boxes. Subsequently, part of the gas enters the fixing plate 51 through the diversion of the connecting pipe 64, and then the gas enters the plurality of connecting seats 52. The gas squeezes the plurality of inner lining plates 53 to extend and clamp and support both sides of the packaging paper box. When the first electric slider 12 continues to slide, it will squeeze out the excess gas. On the premise of ensuring the support and clamping at the plurality of connecting seats 52, the excess gas is discharged externally by the matching components, thereby improving the effect of the long-distance grasping and feeding of a plurality of packaging paper boxes; when the gas in the fourth cylinder 6 is squeezed by the first electric slider 12 and sent into the flow dividing box 63, at this time, the program controls the second solenoid valve 71 to be in the closed state and the first solenoid valve 7 to be in the open state. A large amount of gas is introduced into the inside of the third cylinder 5 to drive the fixing plate 51 to slide downward and the plurality of inner lining plates 53 to extend. When the first electric slider 12 continues to slide and squeeze, excess gas will be generated. Subsequently, the program controls the first solenoid valve 7 to close and the second solenoid valve 71 to open, and the excess gas is discharged from the second solenoid valve 71. When a plurality of packaging paper boxes are sent to the workstation at a long distance, the first solenoid valve 7 is opened to deflate, and the elastic member 54 pulls the inner lining plate 53 to reset, and the packaging paper box is lowered, playing a role in controlling the gas flow at the flow dividing box 63;

[0042] When multiple inner liners 53 slide out of the interior of the connecting seat 52, they cooperate with the extrusion plate 8 with a trapezoidal surface to simultaneously extrude the outer wall of the packaging carton. By increasing the contact area with the packaging carton, the stability of grasping and supporting the packaging carton is improved.

[0043] When clamping and grasping multiple packaging cartons, two friction pads 9 are respectively fixed on the mating plate 16 and the fixing frame 14 to fit against the outer walls of the two packaging cartons, and cooperate with multiple anti-slip protrusions to increase friction, reducing the occurrence of the packaging cartons falling off during the grasping process.

[0044] When multiple connecting seats 52 are installed below the sliding plate 15, the through slots 91 provided on the fixing frame 14 facilitate the displacement of the multiple connecting seats 52. Thus, when the second electric slider drives the sliding plate 15 to slide and adjust the quantity of grasped packaging cartons, it is not restricted by the installation of the connecting seats 52, and the connecting seats 52 can slide past through the through slots 91 when adjusting the grasping quantity of the packaging cartons, improving the adaptability of the grasping device to adjust the grasping quantity.

[0045] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
