Description

TECHNICAL FIELD

[0001] The present application relates to a carton frame positioning production process for carton frame positioning production. BACKGROUND

[0002] Carton frame positioning production refers to positioning the carton frame board in an unfolded state on the face paper to facilitate subsequent production of the carton frame and the carton. The prior art carton frame positioning production, when the size (referring to the circumference length) of the carton frame is small, the length of the face paper and the frame board is also small, and automatic production can be performed by using a frame positioning machine; but when the size of the carton frame is large, since the size of the face paper is limited by the die-cutting indentation equipment and the length is generally not more than 1.1m, the positioning production of the face paper of half of the frame can only be performed on the frame positioning machine, and the positioning production of the face paper of the other half of the frame can only be performed manually, which is low in production efficiency. SUMMARY

[0003] In view of the deficiencies of the prior art, the purpose of the present application is to provide a carton frame positioning production process which realizes automatic positioning production of large-size carton frames by using a splicing method and improves work efficiency.

[0004] To solve the above technical problems, the first process method adopted by the present application is:

[0005] The paper box frame positioning production process is characterized in that: the frame positioning product is composed of first and second two face papers spliced at the head and tail and first and second two frame boards spliced at the head and tail; during work, the positioning conveying table alternately performs first and second conveying actions, the first conveying action is relatively short, the first face paper in the waiting station is sent to the first positioning station, the second conveying action is relatively long, the second face paper in the waiting station is sent to the second positioning station, the first and second positioning stations are separated by a distance slightly smaller than the length of the face paper and equal to the length of the frame board; first, the positioning conveying table performs the first conveying action, the first face paper in the waiting station is sent to the first positioning station, and the second face paper is sent to the waiting station at the same time, then the first suction nozzle assembly places the grabbed first frame board on the first face paper to make the first frame board and the first face paper adhere together, and then the first nozzle assembly lifts the first frame board and the first face paper together; then, the positioning conveying table performs the second conveying action, the second face paper in the waiting station is sent to the second positioning station, and the subsequent first face paper is sent to the waiting station at the same time, then the first and second suction nozzle assemblies perform synchronous actions, the first suction nozzle assembly places the grabbed first frame board and the first face paper, and the second suction nozzle assembly places the grabbed second frame board on the second face paper, so that the first and second face papers and the first and second frame boards adhere to each other to form the frame positioning product; finally, the first suction nozzle assembly releases the first frame board, the second suction nozzle assembly releases the second frame board, the positioning conveying table performs the first conveying action again, and the completed frame positioning product is conveyed to the next process, and the subsequent first face paper in the waiting station is sent to the first positioning station, and the subsequent second face paper is sent to the waiting station, and the cycle is repeated to complete the paper box frame positioning production.

[0006] After the above technical scheme is adopted, the first and second two face papers of the same size and the first and second two frame boards of the same size are used as raw materials, the automatic production of the large-specification paper box frame positioning product is realized by using the splicing mode and reasonable splicing action sequence, the work efficiency is improved, and the idea is ingenious. The length of the two face papers spliced at the head and tail matches the circumference of the large-specification paper box frame (there is a little overlap between the two face papers after splicing, and the overlap is adhered by glue), and the length of the two frame boards spliced at the head and tail matches the circumference of the large-specification paper box frame (the two frame boards are close to each other after splicing, and only a small slot gap is left). In addition, the waiting station with a fixed position is specially arranged on the positioning conveying table, the face paper can stay in the waiting station for a short time to preliminarily dry the surface glue, thereby ensuring that the face paper and the frame board can be adhered firmly in the positioning station, and each face paper reaching the waiting station is conveyed together with the conveying action of the positioning conveying table without extra staying time, thereby improving the work efficiency.

[0007] In order to realize that each sheet paper arriving at the waiting station is transmitted together with the transmission action of the positioning conveying table, and the sheet paper arrives at the same position of the waiting station under the premise that the transmission action distance of the positioning conveying table is different, as the preferred technical scheme: when the positioning conveying table performs the transmission action each time, the sheet paper is sent to the positioning conveying table by the bridge conveying table and is sent to the waiting station together with the positioning conveying table, the bridge conveying table is controlled by the servo motor and is different from the starting time of the positioning conveying table; when working, the sheet paper on the bridge conveying table is detected and positioned in advance by the first sensing probe, when the positioning conveying table performs the first transmission action, the servo motor controls the starting time of the bridge conveying table to be earlier, when the positioning conveying table performs the second transmission action, the servo motor controls the starting time of the bridge conveying table to be later, so that the first and second sheet papers arriving at the positioning conveying table and being conveyed together with the positioning conveying table can arrive at the same position of the waiting station under the premise that the transmission distance is different.

[0008] After the above technical scheme is adopted, although the transmission distance of the positioning conveying table when performing the second transmission action is farther than the distance of the first transmission action, because the lag action of the bridge conveying table is controlled, the sheet paper sent out by the bridge conveying table can arrive at the positioning conveying table and be transmitted together with the positioning conveying table later, so that the sheet paper can accurately arrive at the waiting station of the same position of the first transmission action although the second transmission action of the positioning conveying table is far away. That is, although the positioning conveying table has two different transmission distances, the sheet paper can arrive at the waiting station of the fixed position together with the transmission of the positioning conveying table, the design is ingenious, and the production speed is better improved.

[0009] As the preferred technical scheme, the first suction nozzle assembly and the second suction nozzle assembly are installed side by side on the deviation rectifying moving frame, the first suction nozzle assembly is driven to move up and down by the first cylinder, and the second suction nozzle assembly is driven to move up and down by the second cylinder.

[0010] In order to solve the above technical problems, the second process mode adopted by the present application is:

[0011] The frame positioning product is composed of first and second face papers spliced at the head and tail and first and second frame boards spliced at the head and tail. During operation, the positioning conveying table alternately performs first and second conveying actions. The first conveying action has a relatively short distance and sends the first face paper at the waiting station to the first positioning station. The second conveying action has a relatively long distance and sends the second face paper at the waiting station to the second positioning station. The first and second positioning stations are separated by a distance slightly less than the length of the face paper and equal to the length of the frame board. First, the positioning conveying table performs the second conveying action and sends the second face paper at the waiting station to the second positioning station while sending the first face paper to the waiting station. Then, the second suction nozzle assembly places the second frame board placed on the second face paper to make the second frame board and the second face paper adhere to each other. Subsequently, the second nozzle assembly lifts the second frame board and the second face paper. Next, the positioning conveying table performs the first conveying action and sends the first face paper at the waiting station to the first positioning station while sending the subsequent second face paper to the waiting station. Subsequently, the first and second suction nozzle assemblies perform synchronous actions. The second suction nozzle assembly places the second frame board and the second face paper. The first suction nozzle assembly places the first frame board on the first face paper. Thus, the first and second face papers and the first and second frame boards adhere to each other to form the frame positioning product. Finally, the first suction nozzle assembly releases the first frame board, the second suction nozzle assembly releases the second frame board, the positioning conveying table performs the second conveying action again, and the completed frame positioning product is conveyed to the next process. At the same time, the subsequent second face paper at the waiting station is sent to the second positioning station, and the subsequent first face paper is sent to the waiting station. The cycle is repeated to complete the frame positioning production. BRIEF DESCRIPTION OF DRAWINGS

[0023] As shown in Figure 3 , 4 and 5, the first type of carton enclosure positioning production process of the present invention is as follows: first, the fly-over paper feeding component 2 performs back-and-forth paper feeding action to feed the face papers in the face paper feeding area 1 one by one to the over-bridge conveying table 3, the over-bridge conveying table 3 is controlled by a servo motor to convey the face papers, the face papers are detected and positioned by a first sensing probe, and then conveyed to the positioning conveying table 5 after being coated by the glue coating component 4, the positioning conveying table 5 is controlled and driven by a main servo motor; during operation, the positioning conveying table 5 alternately performs first and second conveying actions, the first conveying action is relatively close to convey the first face paper in the waiting station to the first positioning station, the second conveying action is relatively far to convey the second face paper in the waiting station to the second positioning station, the first and second positioning stations are separated by a distance slightly smaller than the length of the face paper and equal to the length of the enclosure board; first, the first face paper is conveyed to the first positioning station, the second face paper is conveyed to the second positioning station, and the first and second enclosure boards are conveyed to the first and second enclosure board positioning stations, respectively, by the fly-over board conveying component 6, the fly-over board conveying component 6 is controlled by a servo motor to convey the first and second enclosure boards to the first and second enclosure board positioning stations, respectively, the first and second enclosure boards are positioned and fixed on the first and second face papers, respectively, by the positioning and fixing component 7, the positioning and fixing component 7 is controlled by a servo motor to position and fix the first and second enclosure boards on the first and second face papers, respectively, the first and second enclosure boards are conveyed to the first and second enclosure board conveying stations, respectively, by the fly-over board conveying component 8, the fly-over board conveying component 8 is controlled by a servo motor to convey the first and second enclosure boards to the first and second enclosure board conveying stations, respectively, and the first and second enclosure boards are conveyed to the first and second enclosure board conveying stations, respectively, by the fly-over board conveying component 9, the fly-over board conveying component 9 is controlled by a servo motor to convey the first and second enclosure boards to the first and second enclosure board conveying stations, respectively. Figure 5The positioning conveying table 5 performs a first conveying action, the first side paper in the waiting station is sent to the first positioning station, and the second side paper sent by the bridge conveying table 3 is sent to the waiting station. At this time, the first suction nozzle assembly 6 and the second suction nozzle assembly 8 respectively grab the first frame plate and the second frame plate from the frame plate loading station 13 (the frame plate in the frame plate loading area 12 is pushed to the frame plate loading station 13 by the pushing plate 11 in advance), and are moved to the upper side of the first side paper. Then, the first suction nozzle assembly 6 places the grabbed first frame plate on the first side paper (at this time, the second suction nozzle assembly 8 remains stationary), so that the first frame plate is adhered to the first side paper, and the first end of the first frame plate protrudes from the first end of the first side paper (after completion, as shown in Figure 5 The first suction nozzle assembly 6 lifts the first frame plate together with the first side paper. Then, the positioning conveying table 5 performs a second conveying action, the second side paper in the waiting station is sent to the second positioning station, and the subsequent first side paper (i.e., the third side paper) sent by the bridge conveying table 3 is sent to the waiting station. During this process, the second side paper passes below the first side paper, and the tail end of the second side paper is slightly staggered with the first end of the first side paper. Then, the first and second suction nozzle assemblies move synchronously, the first suction nozzle assembly 6 places the grabbed first frame plate and the first side paper, the first end of the first frame plate is adhered to the second side paper, the slight staggered part of the first end of the first side paper and the tail end of the second side paper is adhered together, the second suction nozzle assembly 8 places the grabbed second frame plate on the second side paper, and the second frame plate is adhered to the second side paper, the first end of the second frame plate protrudes from the first end of the second side paper, and the tail end of the second frame plate is close to the first end of the first frame plate (after completion, as shown in Figure 5 The first and second side papers and the first and second frame plates are adhered to each other to form a frame positioning product as shown in Figure 1 The first suction nozzle assembly 6 releases the first frame plate, the second suction nozzle assembly 8 releases the second frame plate, and the positioning conveying table 5 performs a first conveying action again to convey the completed frame positioning product to the next process, and at the same time, the subsequent first side paper in the waiting station is sent to the first positioning station, and the subsequent second side paper (i.e., the fourth side paper) is sent to the waiting station. The first suction nozzle assembly 6 places the grabbed first frame plate on the first side paper, and the first frame plate is adhered to the first side paper (after completion, as shown in Figure 5 The positioning conveying table performs a second conveying action again, and after the positioning action is completed, as shown in Figure 5 The first and second side papers and the first and second frame plates are adhered to each other to form a frame positioning product as shown in Figure 1The shown paper box frame positioning production. In the above production process, the surface paper in the waiting station can be preliminarily dried to ensure that the surface paper can be firmly adhered to the frame plate in the first and second positioning stations; in addition, if the first and second surface paper enters the positioning conveying table 5 with a deviation, the positioning conveying table is provided with a second sensing probe in the waiting station to detect, the second sensing probe will send a signal to control the positioning conveying table 5 to correct the deviation, so that the surface paper reaches the accurate position of the waiting station, in addition, the positioning conveying table 5 is provided with a third sensing probe in the positioning station to detect whether the surface paper reaches the accurate position of the positioning station, if there is a position and direction deviation, the third sensing probe will send a signal to control the moving frame 10 to move and correct the deviation, adjust the first and second suction nozzle assemblies and the frame plate grabbed by them, so that the position of the frame plate is adapted to the surface paper, and the accurate position of the surface paper and the frame plate is ensured.

[0024] The surface paper on the bridge conveying table 3 is sent to the positioning conveying table in the following way: when the positioning conveying table 5 performs a conveying action each time, the bridge conveying table 3 sends the positioned surface paper to the positioning conveying table and sends it to the waiting station with the positioning conveying table, the starting time of the bridge conveying table 3 controlled by the servo motor is different from that of the positioning conveying table 5; when working, the surface paper on the bridge conveying table 3 is preliminarily detected by the first sensing probe, when the positioning conveying table 5 performs a conveying action, the servo motor controls the bridge conveying table 3 to start earlier, when the positioning conveying table 5 performs a second conveying action, the servo motor controls the bridge conveying table 3 to start later, so that the first and second surface papers reaching the positioning conveying table 5 and conveyed by the positioning conveying table 5 can reach the same position of the waiting station under the premise of different first and second conveying distances.

[0025] The first suction nozzle assembly 6 and the second suction nozzle assembly 8 are installed side by side on the same moving frame 10, the moving frame 10 can move horizontally and vertically, and the first suction nozzle assembly 6 and the second suction nozzle assembly 8 can be horizontally adjusted in angle, the first suction nozzle assembly 6 is driven to move up and down by the first air cylinder 7, the second suction nozzle assembly 8 is driven to move up and down by the second air cylinder 9, the positioning conveying table 5 is provided with a surrounding frame plate feeding station 13 in the direction of the inner side of the first and second positioning stations, the first surrounding frame plate and the second surrounding frame plate are arranged in the surrounding frame plate feeding station 13 in sequence during work, the surrounding frame plate feeding station 13 is provided with a surrounding frame plate feeding area 12 in the direction of the inner side, and a pushing plate 11 that moves back and forth is arranged between the surrounding frame plate feeding station 13 and the surrounding frame plate feeding area 12, the pushing plate 11 pushes the surrounding frame plate in the surrounding frame plate feeding area 12 to the surrounding frame plate feeding station 13 to wait when the pushing plate 11 moves. The advantages of the above design are that: the first and second suction nozzle assemblies simultaneously grab the first and second surrounding frame plates from the surrounding frame plate feeding station during work, but the second suction nozzle assembly does not lower the grabbed second surrounding frame plate together with the first surrounding frame plate when the first suction nozzle assembly lowers the grabbed first surrounding frame plate to be placed on the first paper, so that the front end of the second surrounding frame plate does not collide with the rear end of the completed surrounding frame positioning product conveyed in front to cause adhesion (see Figure 5 the middle (D) state, if the second surrounding frame plate is also lowered at this time, it will definitely cause adhesion with the tail end of the first paper), so that the design conveying distance of the positioning conveying table one-time conveying action can be shortened as much as possible, and the design conveying distance of the positioning conveying table two-time conveying action is also shortened correspondingly, and the work efficiency is improved.
