Description

Technical Field

[0001] This invention belongs to the field of packaging box production, and in particular relates to an automatic patching production line for high-quality packaging box inner lining boards. Background Technology

[0002] As people's living standards improve, their demands for goods are increasing. Today, with a dazzling array of products available, the first thing that often catches the eye is the packaging. Good packaging can significantly boost sales. This is especially true for high-end products, where packaging plays a crucial role in attracting consumers, increasing the product's added value, satisfying consumers' emotional needs, and strengthening the brand and corporate image.

[0003] To enhance brand image and quality, and to accommodate the insertion of anti-counterfeiting documents, some high-end product packaging, such as wine boxes, incorporates rivets during production. However, installing rivets on traditional cardboard packaging is prone to damage at the rivet holes, affecting the overall strength and quality of the packaging. To address this, a strip with a metal patch has been placed inside the box at the punched-out locations. However, attaching the metal patch to the existing strip is typically done manually, which is time-consuming, labor-intensive, inefficient, inaccurate, and costly. Furthermore, when rivets are needed on different box models or their positions change, each rivet must be re-aligned and reattached, which is extremely inconvenient. Therefore, a better and faster method is desired to accomplish this task. Summary of the Invention

[0004] The purpose of this invention is to provide an automated patching production line for high-quality packaging box inner linings that features fast patching speed, precise patching, adjustable patching distance, and a high degree of automation.

[0005] This invention is achieved through the following technical solution: An automated patch production line for high-quality packaging box inner lining boards includes a work platform 1. Above the work platform 1, a square arrangement of feeding stations 100, gluing stations 200, patching stations 300, and unloading stations 400 is evenly distributed. Above the work platform 1, a four-station turntable 2, rotatable relative to the work platform 1, is used to carry material strips 10 sequentially along each station for processing. Corresponding to each station, the four-station turntable 2 is equipped with a material strip support 12 for supporting the material strips 10. Next to the feeding station 100, material strip support 12s are sequentially arranged for feeding the material strips located at the feeding station 100. The feeding mechanism 3 and the feeding robot 4 of the feeding bar 10 are used to pick up the bar from the feeding mechanism 3 and place it on the bar support 12 located on the feeding station 100. Above the gluing station 200, there is a gluing mechanism 5. Next to the patching station 300, there is a patch feeding mechanism 6 for patching the patch 11 on the bar 10 located on the patching station 300. Next to the unloading station 400, there is a bar unloading robot 7 and an unloading conveying platform 8. The bar unloading robot 7 is used to pick up the bar from the unloading station 400 and place it on the unloading conveying platform 8. The chip feeding mechanism 6 includes a chip loading rack 13, a suction and flipping robot 14, a first chip support platform 15, and a second chip support platform 17 arranged in sequence. Above the first chip support platform 15 and the second chip support platform 17, a first chip gripping robot 16 and a second chip gripping robot 18 are also arranged in sequence. The first chip gripping robot 16 is used to transfer the chip 11 on the first chip support platform 15 to the second chip support platform 17, and the second chip gripping robot 18 is used to transfer the chip 11 on the second chip support platform 17 to the material strip located at the chip mounting station 300. The chip loading rack 13 includes four chip loading slots 131 arranged side by side. The suction and flipping robot 14 is used to pick up the chip 11 from the chip loading rack 13 and flip it to place it on the first chip support platform 15. The suction and flipping robot 14 includes a flipping arm 141, which is equipped with four suction heads for picking up chips from the four chip loading slots 131 respectively. The first chip support platform 15 and the second chip support platform 17 are each equipped with a position corresponding to the four chip loading slots 131. Four support bases 151 are provided for supporting the patches 11. These four support bases 151 are designated as first, second, third, and fourth support bases, respectively. Below the first patch support base 15, there is a first driving device for driving the first and third support bases to rotate synchronously by 90°, and a second driving device for driving the second and fourth support bases to rotate synchronously by 90°. The first and second driving devices rotate in opposite directions to facilitate relative rotation of the first and second support bases and the third and fourth support bases, thus allowing the four patches 11 to rotate relative to each other. The two components rotate relative to each other. On the second patch support platform 17, two eighth linear drive mechanisms 171 are respectively provided for driving the second and third support seats to move left and right, so as to realize the required variable distance between the two patches 11 located in the middle before patching, to adapt to different patching distance requirements. The tops of the first patch gripping robot 16 and the second patch gripping robot 18 are both fixedly connected to the movable end of a vertically arranged ninth linear drive mechanism 19. The ninth linear drive mechanism 19 is mounted on a tenth linear drive mechanism 21 horizontally mounted above the work platform 1 via a crossbeam 20, so as to simultaneously move the first patch gripping robot 16 and the second patch gripping robot 18 up, down, left, and right. This allows the first patch gripping robot 16 to transfer the patches 11 on the first patch support platform 15 to the second patch support platform 17, and the second patch gripping robot 18 to transfer the patches 11 on the second patch support platform 17 to the material strip located at the patching station 300.

[0006] Preferably, the patch loading trough 131 is inclined downward so that the patches 11 can move downward sequentially under the action of gravity so that the suction head on the flipping arm 141 can pick them up.

[0007] Preferably, each support base 151 on the first patch support platform 15 is fixedly connected to a pulley 156 below it. The pulleys 156 below the first and third support bases are connected together by a drive belt 157 so that the drive belt can drive the two support bases to rotate together. The pulleys 156 below the second and fourth support bases are connected together by another drive belt 157 so that the drive belt can drive the two support bases to rotate together. The movable end of the first drive device 152 is fixedly connected to a drive belt 157 by a fixing block 154 to drive the drive belt 157 as needed. The second drive device 153 rotates, and its movable end is fixedly connected to another transmission belt 157 via another fixed block 154 to drive the transmission belt 157 to rotate as needed. On the first patch support platform 15, next to the four support seats 151, there is also a guide rod 155 parallel to the arrangement direction of the four support seats to guide the movement of the fixed block 154. Thus, it is convenient to drive the first and third support seats to rotate synchronously by 90° via the first drive device 152, and drive the second and fourth support seats to rotate synchronously by 90° via the second drive device 153. After rotation, the four patches 11 turn towards each other in pairs.

Furthermore, a guide rod 185 is provided on the support crossbeam 181 next to the connecting rod 183 to guide the connecting rod when it moves up and down. Since the connection between the vertical cylinder and the connecting rod is a circular structure, when the ninth linear drive mechanism 19 moves the vertical cylinder 182 downward and the moving end of the vertical cylinder 182 presses down, there will be a buffering force on the connecting rod. Thus, through the cooperation of the ninth linear drive mechanism 19, the vertical cylinder 182 and the connecting rod 183, the pressing head 184 can press the patch 11 onto the strip 10 that has been coated with glue very gently.

[0015] Preferably, the material feeding mechanism 3 is fixedly connected to the movable end of at least one fourth linear drive mechanism 36 vertically arranged on the working platform 1, so as to raise or lower the height of the material feeding mechanism 3 relative to the working platform 1 as a whole according to actual production needs.

The first chip gripping robot 16 is used to transfer the chip 11 on the first chip support platform 15 to the second chip support platform 17, and the second chip gripping robot 18 is used to transfer the chip 11 on the second chip support platform 17 to the material strip located at the chip mounting station 300. The chip loading rack 13 includes four chip loading slots 131 arranged side by side. The suction and flipping robot 14 is used to pick up the chip 11 from the chip loading rack 13 and flip it to place it on the first chip support platform 15. The suction and flipping robot 14 includes a flipping arm 141, which is equipped with four suction heads for picking up chips from the four chip loading slots 131 respectively. The first chip support platform 15 and the second chip support platform 17 are each equipped with a position corresponding to the four chip loading slots 131. Four support bases 151 are provided for supporting the patches 11. These four support bases 151 are designated as first, second, third, and fourth support bases, respectively. Below the first patch support base 15, there is a first driving device for driving the first and third support bases to rotate synchronously by 90°, and a second driving device for driving the second and fourth support bases to rotate synchronously by 90°. The first and second driving devices rotate in opposite directions to facilitate relative rotation of the first and second support bases and the third and fourth support bases, thus allowing the four patches 11 to rotate relative to each other. The two components rotate relative to each other. On the second patch support platform 17, two eighth linear drive mechanisms 171 are respectively provided for driving the second and third support seats to move left and right, so as to realize the required variable distance between the two patches 11 located in the middle before patching, to adapt to different patching distance requirements. The tops of the first patch gripping robot 16 and the second patch gripping robot 18 are both fixedly connected to the movable end of a vertically arranged ninth linear drive mechanism 19. The ninth linear drive mechanism 19 is mounted on a tenth linear drive mechanism 21 horizontally mounted above the work platform 1 via a crossbeam 20, so as to simultaneously move the first patch gripping robot 16 and the second patch gripping robot 18 up, down, left, and right. This allows the first patch gripping robot 16 to transfer the patches 11 on the first patch support platform 15 to the second patch support platform 17, and the second patch gripping robot 18 to transfer the patches 11 on the second patch support platform 17 to the material strip located at the patching station 300.

[0031] Each support base 151 on the first patch support platform 15 is fixedly connected to a pulley 156 below it. The pulleys 156 below the first and third support bases are connected together by a drive belt 157 so that the drive belt can drive the two support bases to rotate together. The pulleys 156 below the second and fourth support bases are connected together by another drive belt 157 so that the drive belt can drive the two support bases to rotate together. The movable end of the first drive device 152 is fixedly connected to a drive belt 157 by a fixing block 154 so as to drive the drive belt 157 to rotate as needed. The movable end of the second drive device 153 is fixedly connected to another transmission belt 157 via another fixed block 154 to drive the transmission belt 157 to rotate as needed. On the first patch support platform 15, next to the four support seats 151, there is also a guide rod 155 parallel to the arrangement direction of the four support seats to guide the movement of the fixed block 154. Thus, it is convenient to drive the first and third support seats to rotate synchronously by 90° via the first drive device 152, and drive the second and fourth support seats to rotate synchronously by 90° via the second drive device 153. After rotation, the four patches 11 turn towards each other in pairs.

The movable end of the vertical cylinder 182 has a circular structure, and a connecting rod 183 is pin-connected to the movable end of the vertical cylinder 182. The other end of the connecting rod 183 passes downward through the support frame 181 and is fixedly connected to a downward pressure head 184 with a vacuum nozzle below. Furthermore, a guide rod 185 is provided on the support crossbeam 181 next to the connecting rod 183 to guide the connecting rod when it moves up and down. Since the connection between the vertical cylinder and the connecting rod is a circular structure, when the ninth linear drive mechanism 19 moves the vertical cylinder 182 downward and the moving end of the vertical cylinder 182 presses down, there will be a buffering force on the connecting rod. Thus, through the cooperation of the ninth linear drive mechanism 19, the vertical cylinder 182 and the connecting rod 183, the pressing head 184 can press the patch 11 onto the strip 10 that has been coated with glue very gently.

The moving platform 73 is fixed on the lead screw 72 by a nut sleeve 75 that is threadedly engaged with the lead screw 72. During operation, the drive motor 71 drives the lead screw 72 to rotate, thereby driving the moving platform 73 to move up and down along the lead screw 72. When the moving platform 73 moves, it is guided by the guide rail 74. The component to be driven in linear motion, such as two glue applicators 51, is fixedly connected to the moving platform 73.

[0046] The first linear drive mechanism 92, the second linear drive mechanism 34, the third linear drive mechanism 35, the fourth linear drive mechanism 36, the seventh linear drive mechanism 56, the eighth linear drive mechanism 171, the ninth linear drive mechanism 19, and the eleventh linear drive mechanism 82 are all cylinder linear drive devices.

[0048] The sixth linear drive mechanism 55 and the tenth linear drive mechanism 21 are linear motor drive devices.

[0049] Work process: The strip 10 is placed from the loading station 100 onto the four-station turntable 2 by the strip loading robot 4 and fixed therein. Then the four-station turntable 2 rotates 90° and brings the strip to the gluing station 200, where the strip is glued by the gluing mechanism. Then the four-station turntable 2 continues to rotate 90° and brings the strip to the patching station 300, where four patches 11 are attached to the strip. Then the four-station turntable 2 continues to rotate 90° and brings the strip to the unloading station 400, where the strip is released and picked up by the strip unloading robot 7 and placed onto the unloading conveyor platform 8. The strip 10 is then pressed by the pressing device 81 on the unloading conveyor platform 8 and enters the next process.

[0050] Specifically, At the loading station 100, the movable end of the first linear drive mechanism 92 located below the loading station 100 pushes upward to open the rocker arm-shaped material strip positioning baffle 9 outward, so that the material strip 10 can be placed into the material strip support 12 located at the station. Then, the material strip loading robot 4 takes the material strip from a hopper on the material strip feeding mechanism 3 and places it on the material strip support 12 located at the loading station 100. Then, the movable end of the first linear drive mechanism 92 retracts downward to retract the rocker arm-shaped material strip positioning baffle 9 inward under the action of the torsion spring, thereby fixing the material strip 10. At the gluing station 200, two parallel gluing devices 51, driven by the fifth linear drive mechanism 54 and the sixth linear drive mechanism 55, press down on the strip 10 twice to perform two transverse gluing operations, thereby obtaining four gluing points on the strip for patch application. While gluing, the strip is pressed down by a clamping mechanism located on its side to prevent it from being affected by the gluing force of the gluing device. At the placement station 300, the material-flipping robot 14 picks up the patch 11 from the four patch loading racks 13 and flips it onto the first patch support platform 15. The first patch support platform 15 is driven by the first and second driving devices to make the first and second support seats rotate relative to each other, and the third and fourth support seats rotate relative to each other, that is, to make the four patches 11 turn relative to each other in pairs. After turning, the four patches are transferred to the second patch support platform 17 by the first patch gripping robot 16. The second patch support platform 17 is driven by two eighth linear drive mechanisms 171 to realize the required pitch change between the two patches 11 located in the middle. After pitch change, the four patches are transferred to the placement station 300 by the second patch gripping robot 18 for patching. At the unloading station 400, the movable end of the first linear drive mechanism 92 located below the unloading station 400 is pushed upward to open the rocker arm-shaped material strip positioning baffle 9 outward, thereby releasing the material strip 10 located on the material strip support platform. Then, the material strip unloading robot 7 removes the material strip from the unloading station 400 and places it on the unloading conveying platform 8. The material strip 10 is pressed on the unloading conveying platform 8 by the pressing device 81 and then enters the next process.
