Description

Technical Field

[0001] This invention relates to the field of cardboard processing technology, and in particular to a fully automatic cardboard protective buckle assembly machine. Background Technology

[0002] With the rapid development of the logistics industry, the demand for cardboard boxes, as an important packaging material, is increasing daily. Cardboard boxes require ventilation during the storage and transportation of fruits or special items to prevent spoilage. Therefore, the assembly of protective buckles is a crucial step in the production of such boxes. These buckles enable ventilation, enhance the structural strength of the box, and prevent animals such as rats and cockroaches from entering through the vents. Protective buckles are typically assembled from two components mounted on the inner and outer sides of the box. Traditional assembly relies heavily on manual labor, requiring workers to manually install the buckles on both sides of the cardboard and fasten them, resulting in low efficiency. While some semi-automated assembly equipment can install buckles on one side, manual intervention is still needed to flip the cardboard and assemble the buckle on the other side, making it difficult to meet the needs of large-scale production.

[0003] In view of this, the inventor made a new invention. Summary of the Invention

Detailed Implementation

[0036] The following is in conjunction with the appendix Figures 1 to 13 The present invention will be described in detail.

[0037] This invention discloses a fully automatic cardboard protective buckle assembly machine, comprising a first assembly mechanism 1 and a second assembly mechanism 2. The first assembly mechanism 1 is equipped with a first conveying platform 11 for feeding cardboard and a first flipping conveying device 3 for flipping and conveying the cardboard to the second assembly mechanism 2. The second assembly mechanism 2 is equipped with a second conveying platform 21. The cardboard of the cardboard box is as follows... Figure 12 As shown, the cardboard has mounting holes 8 for assembling the protective buckle. The protective buckle is composed of fasteners a6 and b7 that interlock with each other. See [reference image for shapes of fasteners a6 and b7]. Figure 13The cardboard has two opposite sides. One side of the cardboard is equipped with fastener a6 on the first conveying platform 11 and then transported to the second conveying platform 21 by the first flipping conveying device 3. The other side of the cardboard is equipped with fastener b on the second conveying platform 21, and the protective buckle is then assembled.

[0038] The first assembly mechanism 1 is equipped with a first fastener feeding device 4, and a first support 12 is provided on the first conveying platform 11. A first fastener assembly device 13 is provided on the first support 12. The first fastener assembly device 13 can grab fastener a6 from the first fastener feeding device 4 and assemble fastener a6 onto the cardboard. Cardboard boxes typically have four sides and side panels that form the top and bottom of the box. Protective fasteners are usually required at two locations on the cardboard to allow ventilation. In this solution, two sets of first fastener feeding devices 4 and first fastener assembly devices 13 are symmetrically arranged. The two first fastener feeding devices 4 simultaneously grab fastener a6 from their respective first fastener feeding devices 4 and assemble them onto the mounting holes 8 of the cardboard.

[0039] See Figure 7 The first fastener feeding device 4 is equipped with a vibrating feeder 41, a conveying channel 42, and a preparation platform 43 located at the discharge end of the conveying channel 42. The preparation platform 43 has a material dispensing port 44. Fasteners a6 are stacked in the vibrating feeder 41. The vibrating feeder 41 in this embodiment uses vibration to transport fasteners a6 through the conveying channel 42. This method is a commonly used vibration conveying technology in the prior art, and its specific structure will not be described in detail in this invention. Fasteners a6 are transported out from the conveying channel 42 and enter the material dispensing port 44 of the preparation platform 43. The first fastener assembly device 13 picks up fasteners a6 from the material dispensing port 44 and assembles them onto the mounting holes 8 of the cardboard.

[0040] See Figure 8The first fastener assembly device 13 is provided with a first guide rail 1301 fixedly connected to the first bracket 12. A moving module a1302 is provided on the first guide rail 1301. A first motor 1303 is provided at one end of the first guide rail 1301, which can drive the moving module a1302 to move linearly along the first guide rail 1301. The moving module a1302 is provided with a first cylinder 1304. The first cylinder 1304 extends downward and a first gripper 1305 is provided at the extended end. A bidirectional support clamp 1306 is provided inside the first gripper 1305. The first motor 1303 drives the moving module a1302 to move, causing the first gripper 1305 to move above the material preparation table 43. The bidirectional support clamp 1306 corresponds to the position of the material picking port 44. Then, the first cylinder 1304 drives the first gripper 1305 to move downward, causing the bidirectional support clamp 1306 to extend into the fastener a6. Then, the bidirectional support clamp 1306 opens to grab the fastener a6. Then, the first cylinder 1304 drives the first gripper 1305 to reset. The first motor 1303 drives the first gripper 1305 to move above the mounting hole 8 of the cardboard. The first cylinder 1304 drives the first gripper 1305 to press down against the cardboard, assembling the fastener a6 into the mounting hole 8. The fastener a6 is then installed.

[0041] The bidirectional support clamp 1306 is provided with a first curved arm 1307 and a second curved arm 1308 that are symmetrically arranged. The bent parts of the first curved arm 1307 and the second curved arm 1308 are movably connected to a first gripper 1305. A first support arm 1309 is provided at one end of the first curved arm 1307, and a second support arm 1310 is provided at one end of the second curved arm 1308. Both the first support arm 1309 and the second support arm 1310 are provided with a transverse guide opening 1311. A positioning rod 1312 is provided inside the first gripper 1305, passing through the transverse guide opening 1311. A third cylinder 1313 is provided inside the first gripper 1305. The other ends of the first curved arm 1307 and the second curved arm 1308 are movably connected to the extended end of the third cylinder 1313. See also Figure 9When the extended end of the third cylinder 1313 moves downward, it drives the first crank arm 1307 and the second crank arm 1308 to move, causing one end of the first crank arm 1307 and the second crank arm 1308 to separate from each other, so that the first support arm 1309 and the second support arm 1310 separate to support the inner wall of the fastener a6, and the bidirectional support clamp 1306 grabs the fastener a6. After the fastener a6 is installed, the extended end of the third cylinder 1313 retracts upward, and at the same time pulls the first crank arm 1307 and the second crank arm 1308, causing one end of the first crank arm 1307 and the second crank arm 1308 to move closer to each other, and the first support wall and the second support arm 1310 displace to release the fastener a6. Fastener a6 is assembled into the mounting hole 8 of the cardboard by pressing and fastening. The lower end of the first clamp 1305 is in the shape of a ring. When assembling fastener a6, the lower end of the first clamp 1305 can abut against the top of fastener a6 and press fastener a6 into the mounting hole 8 of the cardboard.

[0042] Considering that some cartons have higher ventilation requirements, two protective buckles may need to be installed in the same position. The material preparation table 43 is provided with two material picking ports 44. The first fastener feeding device 4 is provided with a driving device, which can drive the material preparation table 43 to reciprocate, so that the two material picking ports 44 take turns picking up materials from the material conveying channel 42. The driving device in this solution can be a telescopic cylinder, which drives the material preparation table 43 to reciprocate, so that the two material picking ports 44 take turns picking up materials from the material conveying channel 42. The driving device in this solution can also be a gear and rack transmission mechanism, with a rack set at the bottom of the material preparation table 43. The motor drives the gear to rotate, and the meshing of the rack realizes the linear movement of the material preparation table 43, etc. The driving device in this solution is not limited, and its specific structure is a commonly used mechanical transmission structure in the prior art. This solution will not describe the driving device in detail. The function of the driving device is to drive the material preparation table 43 to reciprocate, so that the two material picking ports 44 take turns picking up materials from the material conveying channel 42. Two first grippers 1305 are provided, each corresponding to one of the two material handling ports 44, so as to simultaneously grip two fasteners a6 for installation.

[0043] The first assembly mechanism 1 is equipped with a rack 14 for stacking cardboard. Multiple conveyor belts 141 for supporting and transporting the cardboard are located at the bottom of the rack 14. The rack 14 is equipped with a limiting plate 142, with a certain height difference between the bottom of the limiting plate 142 and the top surface of the conveyor belts 141, allowing individual cardboard pieces to pass through the bottom of the limiting plate 142. In this invention, one side of the cardboard is typically coated to reduce the coefficient of friction on the cardboard surface. The cardboard pieces are stacked within the rack 14, with the bottommost cardboard piece abutting against the conveyor belts 141. See also... Figure 4The bottom of the material rack 14 is equipped with a power roller assembly 144 and a fourth motor 145 that drives the power roller assembly 144 to rotate. Multiple conveyor belts 141 are provided, each fitted onto the power roller assembly 144. When cardboard needs to be transported, the fourth motor 145 drives the power roller assembly 144 to rotate, causing the conveyor belts 141 to roll. The conveyor belts 141 then move the cardboard, transporting it from the bottom of the limiting plate 142 to the first conveying platform 11. Additionally, the surface of the conveyor belts 141 typically has an anti-slip design or is equipped with an anti-slip layer made of materials such as silicone or rubber to increase the friction between the conveyor belts 141 and the cardboard, preventing slippage.

[0044] The material rack 14 is equipped with a guide plate 143, which is inclined. The higher end of the guide plate 143 engages with the conveyor belt 141, and the lower end extends to the first material conveying platform 11. After the cardboard passes under the limiting plate 142, the bottom of the front end of the cardboard contacts the guide plate 143, causing the cardboard to gradually separate from the conveyor belt 141 as it moves forward. Finally, guided by the guide plate 143, the rear end of the cardboard falls into the designated position on the first material conveying platform 11, facilitating the positioning and transportation of the cardboard.

[0045] The first feeding platform 11 is composed of multiple parallel strip-shaped components 111. A first pushing device 5 is disposed below the first feeding platform 11. The first pushing device 5 has pushers 51 extending from the spaces between the strip-shaped components 111 to the top of the first feeding platform 11. The first pushing device 5 can drive the pushers 51 to transport the cardboard from the first feeding platform 11 to the first flipping feeding device 3. Multiple first pushing devices 5 are arranged aligned with each other, and each first pushing device 5 has multiple pushers 51. The pushers 51 push the rear end of the cardboard, causing the cardboard to move, thus realizing the feeding of the cardboard. (See also...) Figure 6 The first pushing device 5 includes a transmission belt 52, synchronous pulleys a53 and b54 connected to the transmission belt 52, and a third motor 55 driving the synchronous pulley a53. The pusher 51 is fixedly connected to the transmission belt 52. The third motor 55 drives the synchronous pulley a53 to rotate, causing the transmission belt 52 to roll and drive the pusher 51 to move. After the cardboard enters the first conveying platform 11 from the material rack 14, the pusher 51 pushes the cardboard to the bottom of the first support 12 for fastener a6 installation. After the fastener a6 is installed, the pusher 51 continues to push forward, pushing the cardboard into the first flipping conveying device 3.

[0046] The synchronous pulleys a53 and b54 are identical in size and shape. The surface of synchronous pulley a53 has three recesses 56, which are equidistant. The center distance between adjacent pushers 51 on the transmission belt 52 is (circumference of synchronous pulley a53 / 3) × n (n is an integer). That is, the center distance between adjacent pushers 51 on the transmission belt 52 is an integer multiple of one-third of the circumference of synchronous pulley a53. This ensures that when pusher 51 reaches synchronous pulley a53 or synchronous pulley b54, pusher 51 is always located at the position corresponding to the recesses 56, preventing pusher 51 from directly contacting synchronous pulley a53 and synchronous pulley b54.

[0047] The first flipping conveyor 3 is equipped with a shaft 31, on which a plurality of feeders 32 are mounted. Each feeder 32 has multiple feeding ports 33 equidistant from the shaft 31, capable of accommodating cardboard. The feeding ports 33 of the feeders 32 are aligned with each other. A servo motor 34 is mounted at one end of the shaft 31, which intermittently drives the shaft 31 to rotate, causing the feeders 32 to transport the cardboard from one side of the first flipping conveyor 33 to the other side and flip the cardboard over. The number of feeding ports 33 is two or more (an even number). When one feeding port 33 is accurately facing the first conveying platform 11, at least another feeding port 33 is accurately facing the second conveying platform 21. This allows cardboard from one feeding port 33 to enter the second conveying platform 21 while another feeding port 33 is receiving cardboard from the first conveying platform 11, thus improving conveying efficiency. The servo motor 34 intermittently drives the shaft 31 to rotate. The number of rotations of the shaft 31 each time is 360° divided by the number of feeding ports 33 of a single feeder 32. When a feeder 32 has eight feeding ports 33, the servo motor 34 drives the shaft 31 to rotate 45° each time. After one feeding port 33 leaves its original position, another feeding port 33 takes over. The first pushing device 5 can drive the pusher 51 to push the cardboard into the feeding port 33. The first flipping feeding device 3 only needs to rotate intermittently in one direction to continuously transport a large number of cardboards to the next station. Moreover, the transported cardboard will automatically flip over without manual intervention, saving manpower and greatly increasing production capacity.

[0048] The second feeding platform 21 is composed of multiple parallel strip components 111. A second pushing device is provided below the second feeding platform 21, with one end of the second pushing device located below the first flipping feeding device 3. The second pushing device is equipped with a pusher 51, which drives the pusher 51 to transport the cardboard from the first flipping feeding device 3 to the second feeding platform 21 and continue to advance it. The structure of the second pushing device is the same as that of the first pushing device 5. The second pushing device drives the pusher 51 to push the cardboard from the feeding port 33 onto the second feeding platform 21. Compared with the state where the cardboard is on the first feeding platform 11, the cardboard has completed one front-to-back flip when it is on the second feeding platform 21. At this time, the fastener a abuts against the second feeding platform 21.

[0049] The second assembly mechanism 2 is equipped with a second fastener feeding device 401. A second support 22 is mounted on the second conveying platform 21, and a second fastener assembly device 23 is mounted on the second support 22. The second fastener assembly device 23 can pick up fastener b7 from the second fastener feeding device 401 and assemble fastener b7 onto the cardboard, thus fastening fastener b7 to fastener a6. The second fastener feeding device 401 has the same structure as the first fastener feeding device 4, also having a vibrating tray 41, a conveying channel 42, and a preparation platform 43. The preparation platform 43 of both the first and second fastener feeding devices 401 has the same structure. Fastener b7 is conveyed out from the conveying channel 42 and enters the feeding port 44 of the preparation platform 43. The second fastener assembly device 23 picks up fastener b7 from the feeding port 44 and assembles it onto the mounting hole 8 of the cardboard, thus fastening fastener b7 to fastener a6.

[0050] The second fastener assembly device 23 is provided with a second guide rail 2301 fixedly connected to the second bracket 22. A moving module b2302 is provided on the second guide rail 2301. A second motor 2303 is provided at one end of the second guide rail 2301, which can drive the moving module b2302 to move linearly along the second guide rail 2301. The moving module b2302 is provided with a second cylinder 2304. The second cylinder 2304 extends downward and a second gripper 2305 is provided at the extended end. A three-way support clamp 2306 is provided inside the first gripper 1305. The second motor 2303 drives the moving module b2302 to move, causing the second gripper 2305 to move above the corresponding material preparation table 43. The three-way support clamp 2306 corresponds to the position of the material picking port 44. Then, the second cylinder 2304 drives the second gripper 2305 to move downward, causing the three-way support clamp 2306 to extend into the fastener b7. Then, the three-way support clamp 2306 opens to grab the fastener b7. The second cylinder 2304 drives the second gripper 2305 to reset. The second motor 2303 drives the second gripper 2305 to move above the mounting hole 8 of the cardboard. The second cylinder 2304 drives the second gripper 2305 downward to assemble the fastener b7 into the mounting hole 8. By pressing the fastener b7, the fastener b7 and the fastener a6 are fastened together, and the protective buckle is assembled.

[0051] The first fastener assembly device 13 and the second fastener assembly device 23 enable the two fasteners of the protective buckle to be fastened together on both sides of the cardboard box. The protective buckle is automatically fed and assembled, resulting in high assembly efficiency.

[0052] See Figure 10 The three-way support clamp 2306 is equipped with a connecting module 2307. The bottom of the connecting module 2307 has three piston grooves 2308, each containing a movable piston block 2309. Each piston block 2309 has a support block 2310. The connecting module 2307 has an air passage 2311 connecting all the piston grooves 2308. An air pipe and an air pump are connected to the air passage 2311. Air is blown through the air passage 2311 to push the piston block 2309 out of the piston groove 2308, thus opening the support block 2310 to grip the fastener b7. The second gripper 2305 has a limiting ring, which is larger than the connecting module 2307 and its position corresponds to that of the piston block 2309. The limiting ring restricts the movement of the piston block 2309. The support block 2310 is as follows: Figure 11 As shown, it includes a thinner first part 2312 and a thicker second part 2313. The second part 2313 and the first part 2312 form a step difference. The second part 2313 can extend into the ring of the fastener b7. The first part 2312 is used to hold the top of the fastener b7. The second cylinder 2304 drives the second gripper 2305 to move downward, so that the first part 2312 can press the fastener b7 into the mounting hole 8 of the cardboard, so that the fastener b7 is fastened with the fastener a6.

[0053] The first guide rail 1301 and the second guide rail 2301 are each equipped with multiple sensors 1314. The moving module a1302 and the moving module b2302 are equipped with metal pieces 1315 that can be sensed by the sensors 1314. When the moving module a1302 and the moving module b2302 move rapidly, the metal pieces 1315 enter the sensing position of the sensor 1314, and the first motor 1303 or the second motor 2303 will stop suddenly to ensure that the first gripper 1305 and the second gripper 2305 stay in the designated position, thereby improving accuracy.

[0054] Considering that the cardboard needs to be flipped over after the protective buckle is installed so that the inspection equipment can check the finished quality of the cardboard, or to facilitate the subsequent assembly of the cardboard into cartons, in this solution, the second assembly mechanism 2 is equipped with a second flipping conveyor device 301, and the second conveyor platform 21 is located between the first flipping conveyor device 3 and the second flipping conveyor device 301. The shape and size of the second flipping mechanism are the same as those of the first flipping mechanism. The second pushing device pushes the cardboard from the conveying port 33 of the first pushing device 5 to the second conveyor platform 21, and then continues to push the cardboard under the second bracket 22 for the installation of the fastener b7. After the protective buckle is installed, the second pushing device pushes the cardboard into the conveying port 33 of the second flipping conveyor device 301. Of course, depending on the actual usage requirements, a third pushing device with the same structure as the first pushing device 5 can be set on the other side of the second flipping mechanism to facilitate pushing the cardboard transported by the second flipping mechanism to a carton folding machine or quality inspection equipment, etc.
