Description

Technical Field

[0001] The invention relates to the technical field of packaging box production, in particular to a cardboard gluing, buckling and turning all-in-one machine and a cardboard buckling method. Background Art

[0002] Since some packaging boxes require a snap fastener to securely fit the box lid onto the box body, the snap fastener must be assembled into a snap fastener hole in the cardboard during the production process. In the prior art, to improve the efficiency of attaching the snap fastener to the cardboard, the snap fastener and cardboard are typically assembled using automated equipment. Among the existing patents, the Chinese patent document with application number 202011557522.3 discloses an automatic frame assembly equipment, including a plastic parts loading station, a metal parts vibration plate assembly and a metal parts linkage loading robot, etc. A staff member is respectively set at the plastic parts loading station and the frame loading station to perform the initial plastic parts and frame loading. After manual loading, the plastic parts flow on the carrier circulation line with the floating carrier. At the same time, the metal parts are arranged in sequence through the metal parts vibration plate assembly and transferred to the working range of the metal parts linkage loading robot. The metal parts linkage loading robot grabs the metal parts onto the plastic parts, and the metal parts and plastic parts continue to move with the floating carrier. The product automatic assembly detection component buckles the metal parts into the plastic parts and detects the height of the buckled products. The semi-finished product automatic assembly robot arm assembly grabs the buckled products to the frame and assembles them with the frame. Finally, the finished product is lowered and transported by the frame lifting assembly. This patent document requires two workers to load the plastic parts and the frame respectively, which has a low degree of automation and low production efficiency.

[0003] There is also a Chinese patent document with application number 202211034645.8 that discloses a snap-on gray plate assembly process, in which the snap is moved to the work station with the protruding part facing upward; the glue spraying process: glue is sprayed on the flat part of the snap; the assembly process: the gray plate is moved above the snap, with the outside of the gray plate facing downward and the inside facing upward, and is plugged into the snap from top to bottom. Output process: the assembled snap-on gray plate assembly is output outward. This patent document moves the gray plate downward so that the gray plate and the snap are plugged together. The plug-in between the gray plate and the snap is not firm and is easy to fall off. A pressing mechanism needs to be added for pressing, which increases the cost. The conveying process of the gray plate and the snap is complicated, and the feeding is inconvenient and inefficient.

[0004] Therefore, the defects are very obvious and a solution is urgently needed. Summary of the Invention

[0036] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0037] like Figures 1 to 7 As shown, the present invention provides a cardboard gluing, buckling and flipping integrated machine, which includes a machine 1, a cardboard feeding device 2, a board feeding device 3, a gluing device 4, a first positioning device 5, a flipping device 6, a buckling robot 7, a buckle supply device 8 and a push plate mechanism 9. The cardboard feeding device 2 is mounted on the machine 1, and the gluing device 4, the first positioning device 5 and the flipping device 6 are sequentially arranged on the machine 1 along the board feeding direction of the board feeding device 3. The gluing device 4 is located above the board feeding device 3. The board feeding device 3 is used to transport the cardboard supplied by the cardboard feeding device 2 to the gluing device 4, the first positioning device 5 and the flipping device 6 in sequence. The buckle supply device 8 is arranged on one side of the machine 1, and the buckle punching robot 7 is movably arranged above the first positioning device 5 and the buckle supply device 8. The push plate mechanism 9 is used to push out the cardboard after being flipped by the flipping device 6; specifically, the cardboard can be a frame.

[0038] In actual application, the cardboard feeding device 2 with multiple cardboards stacked on it supplies the bottom layer of cardboard to the feeding device 3. At this time, the feeding end of the feeding device 3 not only transports the bottom layer of cardboard in the cardboard feeding device 2 to the first positioning device 5, the first positioning device 5 positions the cardboard, but also transports the cardboard positioned by the first positioning device 5 to the turning device 6. In the process of transporting the bottom layer of cardboard to the first positioning device 5, the gluing device 4 applies glue to the button hole position of the cardboard to achieve gluing while the cardboard moves. At the same time, the buckle supply device 8 supplies the buckle to the buckle position, the buckle robot 7 picks up the buckle and presses the buckle into the button hole of the cardboard positioned by the first positioning device 5, and the glue sticks the buckle to the button hole of the cardboard. The turning device 6 flips the cardboard with the buckle glued 180°, and the pushing plate mechanism 9 pushes out the cardboard after flipping 180°, so as to facilitate subsequent processing of the cardboard after the buckle is installed (for example, veneer paper on the cardboard after the buckle is installed). The invention realizes the automatic conveying, gluing, buckling (buckle punching / pressing) and 180-degree turning of cardboard, the buckling is firmly installed and not easy to fall off, and the efficiency of processing the cardboard is improved.

[0039] In this embodiment, the cardboard gluing, buckling and flipping machine also includes a second positioning device 91 arranged on the side of the flipping device 6 away from the first positioning device 5, and the pushing plate mechanism 9 is used to push the flipped cardboard to the second positioning device 91; the cardboard gluing, buckling and flipping machine also includes a surface paper feeding mechanism 93 arranged on the side of the second positioning device 91 away from the flipping device 6 and an assembly robot 92 installed on the machine 1 and movably arranged above the second positioning device 91 and the surface paper feeding mechanism 93. The assembly robot 92 is provided with a visual positioning mechanism, and the visual positioning mechanism can use a CCD camera.

[0040] In actual application, the push plate mechanism 9 pushes the cardboard flipped by the flipping device 6 to the second positioning device 91, and the second positioning device 91 positions the cardboard. At the same time, the facial paper feeding mechanism 93 transports the glued facial paper to the veneer paper station, so that the facial paper is located on the front side of the cardboard. The visual positioning mechanism on the assembly robot 92 first visually locates the hole position of the facial paper and / or the position of the buckle on the cardboard, then picks up the cardboard assembled with the buckle and accurately assembles the cardboard on the facial paper to achieve the gluing of the cardboard with the buckle and the facial paper. After the veneer paper, the facial paper feeding mechanism 93 sends the cardboard after veneer paper out.

[0041] In this embodiment, the cardboard feeding device 2 includes a storage bin mounted on the machine 1. The machine 1 is provided with a plurality of support plates 11, which form the table of the machine 1. A clearance gap is provided between two adjacent support plates 11, and a cardboard discharge gap is provided between the bottom port of the storage bin and the top surface of the support plate 11. The clearance gap is used to provide clearance space for the feeding end of the cardboard feeding device 3, the flipping end of the flipping device 6, and the pushing end of the pushing mechanism 9. The extension direction of the clearance gap is parallel to the feeding direction of the cardboard feeding device 3, which is parallel to the pushing direction of the pushing mechanism 9. The plurality of support plates 11 support the cardboard, facilitating the cardboard feeding by the cardboard feeding device 3, the 180° flipping of the cardboard by the flipping device 6, and the pushing of the cardboard by the pushing mechanism 9, thereby making the structure of the machine 1, the cardboard feeding device 3, the flipping device 6, and the pushing mechanism 9 compact. The bottom layer of cardboard in the storage bin is located in the cardboard discharge gap, and the cardboard feeding device 3 delivers the cardboard in the cardboard discharge gap. The cardboard feeding device 3 moves back and forth to continuously output the cardboard.

[0042] In this embodiment, the board feeding device 3 includes a mobile driving mechanism 31 installed on the machine 1, a first bracket 32 ​​and a second bracket 33 respectively installed on the driving ends of the mobile driving mechanism 31, a plurality of first pushing structures 34 installed on the first bracket 32 ​​and a plurality of second pushing structures 35 installed on the second bracket 33, the first bracket 32 ​​and the second bracket 33 are arranged in parallel, the first pushing structure 34 moves back and forth between the cardboard feeding device 2 and the first positioning device 5, and the second pushing structure 35 moves back and forth between the first positioning device 5 and the flipping device 6; specifically, the mobile driving mechanism 31 can adopt a linear driving module.

[0043] In actual application, at the beginning, the first pushing structure 34 is located at the rear side below the bottom port of the cardboard feeding device 2, and the second pushing structure 35 is located at the rear side of the first positioning device 5. The cardboard feeding device 2 supplies the bottom layer of cardboard to the pushing end of the first pushing structure 34, and the cardboard at the first positioning device 5 is located at the pushing end of the second pushing structure 35. At this time, the mobile driving mechanism 31 drives the first pushing structure 34 and the second pushing structure 35 to move forward synchronously, so that the first pushing structure 34 pushes the bottom layer of cardboard in the cardboard feeding device 2 to the first positioning device 5. Synchronously, the second pushing structure 35 pushes the cardboard in the first positioning device 5 to the flipping device 6 to realize progressive feeding of cardboard. After pushing the cardboard, the mobile driving mechanism 31 drives the first pushing structure 34 and the second pushing structure 35 to reset backward synchronously to facilitate the next pushing of cardboard.

[0044] In this embodiment, the first pushing structure 34 includes a pushing seat 341, a pushing block 342 and an elastic member 343. The pushing seat 341 is installed on the first bracket 32. The top of the pushing seat 341 is recessed with a pushing avoidance groove 344. The middle part of the pushing block 342 is rotatably set in the pushing avoidance groove 344. The front bottom surface of the pushing block 342 is elastically connected to the bottom wall of the pushing avoidance groove 344 via the elastic member 343. The rear top surface of the pushing block 342 is provided with a rear guide slope 345. The front top surface of the pushing block 342 can protrude outside the top surface of the pushing seat 341, and the rear part of the pushing block 342 is used to contact the bottom wall of the pushing avoidance groove 344; specifically, the elastic member 343 is a spring.

[0045] The top surface of the pushing block 342 is higher than the top surface of the pushing seat 341, so that a pushing step is formed between the pushing block 342 and the pushing seat 341, and the rear portion of the pushing block 342 is in conflict with the bottom wall of the pushing avoidance groove 344, so that the pushing block 342 maintains a stable pushing state. The pushing block 342 in the pushing state is located at the storage area of ​​the cardboard feeding device 2. At the rear side below the bottom port of the hopper, the storage hopper supplies a piece of cardboard to the pushing step formed between the pushing block 342 and the pushing seat 341. The mobile driving mechanism 31 drives the first pushing structure 34 to move away from the storage hopper, so that the pushing block 342 of the first pushing structure 34 pushes the cardboard to the first positioning device 5 to push the material forward. When the cardboard at the bottom of the storage hopper is pushed out, the remaining stacked cardboards in the storage hopper will drop by one cardboard height as a whole. When the first pushing structure 34 needs to push another cardboard, the mobile driving mechanism 31 drives the first pushing structure 34 to move away from the storage hopper. The first pushing structure 34 is reset and moved (reset backward). During the reset and movement of the first pushing structure 34, the backward guide slope 345 plays a guiding role, so that the pushing block 342 on the first pushing structure 34 can gradually move relative to the bottom cardboard of the storage bin. As the pushing block 342 moves from front to back, the top surface of the pushing block 342 will gradually come into contact with the bottom cardboard of the storage bin. The bottom cardboard of the storage bin where multiple cardboards are stacked will apply an extrusion force to the front top surface of the pushing block 342, so that the front of the pushing block 342 compresses the elastic member 343. The pushing block 342 rotates in the pushing avoidance groove 344, causing the pushing block 342 to retract into the pushing avoidance groove 344 until the pushing block 342 moves to the rear side of the storage bin, and the elastic member 343 elastically recovers, and the elastic member 343 stretches to drive the pushing block 342 to rotate, so that the front top surface of the pushing block 342 protrudes outside the top surface of the pushing seat 341 and forms a pushing step until the rear portion of the pushing block 342 contacts the bottom wall of the pushing avoidance groove 344. At this time, the cardboard at the bottom of the storage bin is located on the pushing step, so that the next cardboard can be pushed. The first pushing structure 34 has a simple structure and an ingenious and compact design. It can effectively push the cardboard without scratching the cardboard. When the pushing block 342 retreats and resets, the pushing block 342 can adaptively adjust. There is no sense of drop between the multiple pieces of cardboard stacked in the storage bin, and the stability is good, ensuring that the pushing block 342 can retreat normally and quickly to facilitate pushing the next cardboard. There is no need to configure an additional lifting driver 353 to control the lifting of the pushing block 342, which simplifies the structure and reduces costs.

[0046] Specifically, a fixing hole is recessed on the front bottom surface of the pushing block 342 and / or the bottom wall of the pushing avoidance groove 344, and the end of the elastic member 343 is inserted into the fixing hole to position the elastic member 343, thereby facilitating the disassembly and maintenance of the elastic member 343 and improving the working stability of the elastic member 343.

[0047] In this embodiment, the pusher seat 341 is threadedly connected to a height adjustment stopper 346. The high end of the height adjustment stopper 346 can protrude into the pusher avoidance groove 344 and abut against the rear portion of the pusher block 342. The height adjustment stopper 346 is screwed by a tool to allow the height adjustment stopper 346 to move vertically relative to the pusher seat 341 to adjust the effective length of the height adjustment stopper 346 extending into the pusher avoidance groove 344, thereby adjusting the height of the height adjustment stopper 346 above the bottom wall of the pusher avoidance groove 344. Since the height adjustment stopper 346 abuts against the rear portion of the pusher block 342, changing the relative position of the height adjustment stopper 346 can adjust the inclination angle of the pusher block 342, thereby adjusting the height difference between the front top surface of the pusher block 342 and the top surface of the pusher seat 341, thereby meeting the requirements for pushing cardboards of different thicknesses and improving the stability of the pusher.

[0048] Specifically, the rear top surface of the pusher seat 341 is provided with a backward inclined guide surface, and / or the front top corner of the pusher seat 341 is provided with a chamfer. This structural design facilitates the forward pushing and backward reset of the first pusher structure 34, and also prevents the first pusher structure 34 from scratching the cardboard when it moves back and forth.

[0049] In this embodiment, the second pushing mechanism 35 includes a lifting seat 351 slidably connected to the second bracket 33, one or more push blocks 352 mounted on the lifting seat 351, and a lifting actuator 353 mounted on the second bracket 33 for driving the lifting seat 351 upward and downward. The lifting actuator 353 can be a vertically mounted pneumatic cylinder. In actual application, when the push block 352 is located at the rear side of the cardboard, the moving drive mechanism 31 drives the second bracket 33, together with the lifting seat 351 and the push block 352, to move forward, so that the push block 352 pushes the cardboard from the first positioning device 5 to the turning device 6. Then, when the moving drive mechanism 31 drives the second bracket 33, together with the lifting seat 351 and the push block 352, to reset backward, the lifting actuator 353 drives the lifting seat 351 and the push block 352 downward, so that the push block 352 moves backward and resets under the cardboard. After reset, the lifting actuator 353 drives the lifting seat 351 and the push block 352 upward to facilitate pushing the next cardboard. Since the weight of a single piece of cardboard is not enough to compress the elastic member 343, the structure of the second pushing structure 35 is different from that of the first pushing structure 34. Pushing structures with different structural forms are adopted in different situations, which ensures normal progressive pushing of cardboard while controlling costs and can meet the cardboard pushing needs in different situations.

[0050] In this embodiment, the flip device 6 includes a base 61 installed on the machine 1, a flip shaft 62 rotatably connected to the base 61, a flip driver 63 installed on the base 61 and used to drive the flip shaft 62 to rotate, and a plurality of flip arms 64 installed on the flip shaft 62. The plurality of flip arms 64 are arranged along the axial direction of the flip shaft 62. Clamping grooves 65 are provided at both ends of the flip arm 64, and an elastic clamping member 66 is provided on the inner wall of the clamping groove 65.

[0051] In actual application, at the beginning, the flip arm 64 is in a horizontal state, and the clamping grooves 65 on both ends of the flip arm 64 are facing both sides, so that when one clamping groove 65 is in the feeding state, the other clamping groove 65 is in the discharging state. The mobile drive mechanism 31 drives the second pushing structure 35 to transport the cardboard positioned by the first positioning device 5 into the clamping groove 65 in the feeding state, so that the cardboard is inserted into the clamping groove 65. The elastic clamping member 66 in the clamping groove 65 elastically clamps the cardboard in the clamping groove 65. At the same time, the pushing plate mechanism 9 outputs the cardboard after flipping 180° from the clamping groove 65 in the discharging state. When a cardboard is clamped in the clamping slot 65 in the feeding state and the cardboard in the clamping slot 65 in the discharging state is discharged, the flipping driver 63 drives the flipping shaft 62 to rotate 180 degrees, so that the clamping slot 65 holding the cardboard rotates to the discharging position and the unloaded clamping slot 65 rotates to the feeding position, thereby switching the states of the two clamping slots 65, thereby realizing the flipping of the cardboard, with high flipping efficiency, and facilitating the subsequent veneer application of the cardboard. The flipping device 6 has a simple structure, simple operation, low cost, and can effectively flip the cardboard with high flipping efficiency.

[0052] In this embodiment, the elastic clamping member 66 comprises a plurality of glass ball screws or spring balls threadedly connected to the flip arm 64. The glass balls of the glass ball screws or spring balls can extend into the clamping groove 65. This structural design makes the elastic clamping member 66 simple and low-cost, and can stably clamp the cardboard in the clamping groove 65.

[0053] Specifically, the buckle supply device 8 includes a vibration plate provided on one side of the machine 1, a material rail connected to the discharge port of the vibration plate, a buckle push mechanism installed on the discharge port of the material rail, and a buckle positioning seat provided on one side of the material rail. The buckle positioning seat is provided with a buckle groove, and the buckle push end of the buckle push mechanism is used to push the buckle output from the discharge port of the material rail into the buckle groove. In actual application, a large number of buckles are placed in the vibration plate, and the vibration plate vibrates to move the buckle along the material rail until the buckle moves to the buckle push mechanism. The buckle push mechanism pushes the buckle into the buckle groove of the buckle positioning seat. The buckle groove positions the buckle, ensuring the position accuracy and stability of the buckle, so that the buckle-binding robot 7 can accurately pick up the buckle.

[0054] Preferably, both the first positioning device 5 and the second positioning device 91 can use a clapper positioning method to position the cardboard.

[0055] The present invention also provides a cardboard buckle method, based on the application of the above-mentioned cardboard gluing, buckling and turning all-in-one machine, including the following method steps:

[0056] A. A cardboard feeding device 2 with multiple cardboards stacked on it supplies the bottom layer of cardboard to a cardboard delivery device 3;

[0057] B. The feeding end of the feeding device 3 not only conveys the bottom layer of the cardboard in the cardboard feeding device 2 to the first positioning device 5, which positions the cardboard, but also conveys the cardboard positioned by the first positioning device 5 to the turning device 6 simultaneously; the feeding device 3 moves back and forth to convey the cardboard in a progressive manner;

[0058] C. During step B, when the bottom layer of cardboard is conveyed to the first positioning device 5, the gluing device 4 applies glue to the buttonhole positions of the cardboard, so that the cardboard is gluing (applying glue) while moving.
