Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging paperboard robot automatic processing, more specifically, it relates to a packaging paperboard automatic processing robot and method. BACKGROUND

[0002] Packaging box paperboard is produced and processed through industrial robot systems, among which the positioning and punching processing of paperboard hand hole is the most common using industrial robots. The accurate positioning and punching processing of paperboard hand hole by industrial robots has the following effects: 1. Improving production efficiency: positioning and punching hand hole can help ensure the accurate and consistent position of hand hole, thereby improving production efficiency and reducing adjustment and waste in the production process. 2. Ensure product consistency: positioning and punching hand hole can ensure the consistent position of hand hole of each paperboard packaging box, so that the final product appearance is neat and consistent, improving the overall quality of the product. 3. Convenient to use: reasonably designed hand hole can provide convenient hand carrying method, which is convenient for consumers to carry and use the product, increasing the practicality and convenience of the product. 4. Aesthetics improvement: positioning and punching hand hole helps to make the shape of the hand carrying part regular and beautiful, improving the appearance of the product. 5. Meet the design requirements: in the production of paperboard packaging box, designing fixed position hand hole may be part of the product design, and positioning and punching can ensure production according to design requirements.

[0003] Currently, there are two ways of punching by industrial robots on packaging paperboard: single paperboard single punching and multi-paperboard stacking punching.

[0004] The single paperboard single punching method combines the conveying line with the punching machine. When the single paperboard is transported to the bottom of the punching head, the punching head is driven to punch the paperboard. However, single paperboard single punching increases the processing time of a single paperboard, making the entire production process less efficient. Moreover, single paperboard single punching cannot ensure that the hole positions on each paperboard are the same, resulting in some minor errors.

[0005] The multi-paperboard stacking punching method transports multiple stacked paperboards to the bottom of the punching head through the conveying line, then positions the paperboards, and finally punches the paperboards with the punching head. However, positioning the paperboards can only ensure that the punching hole positions of the multiple paperboards are consistent, while there is a certain gap between the stacked paperboard layers. Since the paperboards are not tightly attached, the paperboards may be unevenly punched, resulting in uneven punching edges, burrs and flash, and even deformation or tearing. In addition, the overall integration of the robot is not high enough. Specifically, the positioning of the paperboard, punching, and ejection of the waste material after punching are all performed separately, which means that each operation requires a separate drive, resulting in increased production costs.

[0023] The beneficial effects of the present application are:

[0024] By utilizing the stroke of the output end of the air cylinder pushing the mounting frame to move downward, the control plate is first pulled by the elastic rope to move to drive the two positioning and correcting plates to position and correct the front and back sides of the preliminarily positioned and corrected paperboard, and the two L-shaped pressing plates are driven to move by the continuous movement of the output end of the air cylinder to press the paperboard on the blanking platform, so as to realize the all-around fixation of the paperboard and ensure the accuracy of blanking.

[0045] Referring to Figure 4 、 Figure 5 and Figure 6 , the control assembly 702 comprises a reset plate two 7021 fixedly installed at the top of the control plate 7012 and two L-shaped plates 7022 fixedly installed at the right side of the support frame 7011 and front and back symmetry, the reset plate two 7021 and the L-shaped plates 7022 are jointly installed with reset springs two 7023, and the right side of the reset plate two 7021 is fixedly installed with two limiting rods three 7024 slidingly penetrating the two L-shaped plates 7022 and front and back symmetry.

[0046] Referring to Figure 1 、 Figure 4 、 Figure 5 and Figure 6 , the left side of the fixing frame 4 is fixedly installed with a fixed pulley two 7025, the top of the support frame 7011 is fixedly installed with a fixed pulley three 7026, the same elastic rope 7027 is wound outside the fixed pulley two 7025 and the fixed pulley three 7026, the left end of the elastic rope 7027 is fixedly connected with the reset plate two 7021, the left side of the mounting frame 604 extends an extension plate, the right end of the elastic rope 7027 is fixedly connected with the extension plate, and the elastic coefficient of the elastic rope 7027 is greater than the elastic coefficient of the reset springs two 7023.

[0047] Referring to Figure 1 、 Figure 2 and Figure 11 , the top of the machine body 1 is fixedly installed with a double-shaft air cylinder 7018, the baffle 7019 is fixedly installed at the output end of the double-shaft air cylinder 7018, the top of the blanking platform 9 is rotatably installed with front and back symmetrical pulleys 10, and the top of the blanking platform 9 is provided with two blanking ports 6025 matched with the blanking heads 6023.

[0048] Referring to Figure 1 and Figure 2The bottom of the punching platform 9 is fixedly provided with a discharging box 11 corresponding to the discharging port 6025, and a receiving box 12 is movably arranged on the inner wall of the bottom of the machine body 1 and located directly below the discharging box 11.

[0049] In use, in the initial state, the output end of the double-shaft air cylinder 7018 pushes the baffle 7019 to rise above the punching platform 9, and then the stacked paperboard to be punched is conveyed to the top of the punching platform 9 by the left conveying belt 3, and then abuts against the baffle 7019, so that the paperboard is aligned in the left-right direction for preliminary positioning and correction. Then, the air cylinder 5 is started, and the output end of the air cylinder 5 pushes the mounting frame 604 to move downward. First, the extension plate pulls the right end of the elastic cord 7027 to move downward and overcomes the elastic force of the second reset spring 7023 to pull the second reset plate 7021 to move rightward, so as to drive the control plate 7012 to move rightward, and then the control groove 7013 pushes the slide rod 7014 to slide along the inclined groove 7010, so as to drive the two slide rods 7014 to move close to each other, and the two positioning and correction plates 7016 move close to the paperboard and push the paperboard, so as to generate a pressing force on the paperboard. The pressing force presses the paperboard against the baffle 7019, so as to ensure the position of the paperboard in the front-rear direction, and then the positioning and correction of the stacked paperboard in the front-rear and left-right directions are realized, so as to ensure that the paperboard is in a completely stable and accurate position on the punching platform, thereby improving the punching accuracy and the punching quality, and reducing the waste rate. Then, the output end of the air cylinder 5 continues to push, and the punching unit 6 punches the paperboard. In this process, the elastic cord 7027 gradually extends as the extension plate moves downward.

[0050] When the punching is completed, the output end of the air cylinder 5 drives the extension plate to move upward. First, the elastic cord 7027 begins to gradually contract. When the elastic cord 7027 is completely contracted, the second reset spring 7023 releases its elastic potential energy, drives the control plate 7012 to move leftward, and then drives the two positioning and correction plates 7016 to reset.

[0051] Referring to Figure 7 , Figure 8 , Figure 9 and Figure 10 , the pressing assembly 601 comprises a mounting plate 6011 fixedly arranged at the bottom of the mounting frame 604, and the bottom of the mounting plate 6011 is fixedly provided with L-shaped pressing plates 6013 through two buffer springs 6012 arranged symmetrically left and right.

[0052] Referring to Figure 7 , Figure 8 , Figure 9 and Figure 10The blanking assembly 602 includes a moving plate 6022 fixedly installed at the output end of the air cylinder 5 and two blanking heads 6023 fixedly installed at the bottom of the moving plate 6022 in left-right symmetry, the top of the moving plate 6022 is fixedly connected with the mounting frame 604 through a strong spring 6021, the elastic coefficient of the strong spring 6021 is greater than the elastic coefficient of the buffer spring 6012 and the elastic cord 7027, and the length of the blanking head 6023 is greater than the height of the stacked paperboard after being compressed.

[0053] Referring to Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , the top of the moving plate 6022 is fixedly installed with two limit rods two 6024 in front-back symmetry, and the top ends of the limit rods two 6024 slide through the mounting frame 604.

[0054] In specific use, the output end of the air cylinder 5 not only drives the downward movement of the mounting frame 604, but also drives the synchronous downward movement of the two mounting plates 6011, after the positioning and correction assembly 701 positions and corrects the stacked paperboard in four directions of front, back, left and right, the output end of the air cylinder 5 continues to drive the downward movement of the mounting frame 604, so that the L-shaped pressing plate 6013 contacts the paperboard and compresses the paperboard on the top of the blanking platform 9, thereby ensuring that the paperboard remains stable during blanking, and further improving the precision of blanking. Because of the accurate positioning and stable compression of the paperboard before blanking, the blanking quality problem caused by position deviation or shaking can be significantly reduced, thereby reducing the scrap rate and improving the production efficiency. At the same time, the buffer spring 6012 is compressed, until the bottom of the mounting plate 6011 contacts the L-shaped pressing plate 6013, at this time the buffer spring 6012 is compressed to the limit, and the output end of the air cylinder 5 continues to drive the downward movement of the moving plate 6022, and stretches the strong spring 6021 to drive the downward movement of the moving plate 6022, thereby driving the downward movement of the blanking head 6023 to punch the pull hole on the positioned, corrected and compressed stacked paperboard.

[0055] When the blanking is completed, the output end of the air cylinder 5 is retracted to drive the upward movement of the mounting frame 604, and the buffer spring 6012 gradually releases its elastic potential energy with the movement of the mounting frame 604, and finally the L-shaped pressing plate 6013 is separated from the paperboard for resetting.

[0056] Referring to Figure 7 , Figure 8 , Figure 9 and Figure 10 , the ejection assembly 603 includes a reset plate one 6032 fixedly installed at the top of the moving plate 6022 through a reset spring one 6031, and the reset plate one 6032 is fixedly installed with an ejection rod 6033 sliding through the moving plate 6022 and the blanking head 6023 and extending into the ejection cavity.

[0058] In specific use, in the punching process, when the moving plate 6022 moves downward, the fixed pulley one 6035 is driven to move downward, and the pull rope 6036 arranged outside the automatic take-up wheel 6034 is pulled, when the punching is completed, the pull rope 6036 on the automatic take-up wheel 6034 has been completely stretched, and the punching waste may be stuck in the ejection cavity and cannot be discharged from the discharge port 6025, at this time, the output end of the cylinder 5 pushes the moving plate 6022 to continue to move a small distance, at this time, the pull rope 6036 is fixedly connected with the one end of the automatic take-up wheel 6034, the fixed pulley two 7025 continues to move downward, thereby driving the pull rope 6036 to pull the reset plate one 6032 to move downward and compress the reset spring one 6031, thereby driving the ejection rod 6033 to move downward, the punching waste stuck in the ejection cavity after the punching is completed is ejected, and enters the receiving box 12 through the discharge port 6025 and the discharge box 11 to be collected.

[0059] After the punching is completed, the output end of the cylinder 5 is retracted, driving the mounting frame 604 to move upward, in this process, the moving plate 6022 first moves upward, driving the fixed pulley two 7025 to move upward, the reset spring one 6031 is gradually released, driving the reset plate one 6032 to reset, after the reset plate one 6032 resets, the moving plate 6022 continues to move upward, and the automatic take-up wheel 6034 starts to rotate to wind the pull rope 6036.

[0060] Referring to Figures 1-12 , the application also provides a use method of the packaging paperboard automatic processing robot, comprising the following steps:

[0061] S1: the left conveying belt 3 conveys the stacked paperboard to be punched to the top of the punching platform 9 to the right, then abuts against the baffle 7019, so that the paperboard is aligned in the left-right direction to be preliminarily positioned and corrected, then the two positioning and correcting plates 7016 are close to the paperboard and push the paperboard, the paperboard is pressed on the baffle 7019, and the paperboard is positioned in the front-rear direction.

[0062] S2: after positioning and correction, the output end of the cylinder 5 continues to push the mounting frame 604 to move downward, so that the L-shaped pressing plate 6013 contacts the paperboard and presses the paperboard on the top of the punching platform 9.

[0063] S3: After the paperboard is pressed, the output end of the air cylinder 5 continues to push and drive the moving plate 6022 to move downward, and in turn drive the punching head 6023 to move downward, to punch the pull hole on the stacked paperboard which has been positioned, corrected and pressed.

[0064] S4: When the punching is completed, the output end of the air cylinder 5 pushes the moving plate 6022 to continue to move a small distance, drives the ejection rod 6033 to move downward, ejects the punching waste which is clamped in the ejection cavity after the punching is completed, and enters the collection box 12 through the discharge port 6025 and the discharge box 11 to be collected, at the same time drives the baffle 7019 to move downward, starts the conveying belts 3 on the left and right sides, and the next batch of stacked paperboard to be punched is conveyed to the right through the conveying belt 3 on the left side to the process of pushing the punched paperboard to the conveying belt 3 on the right side.
