Description

Technical Field

[0001] This invention relates to the field of cardboard processing equipment technology, and specifically to a highly adaptable cardboard palletizing machine. Background Technology

[0002] Cardboard boxes are used to package various items. After cardboard boxes are produced, multiple un-expanded cardboard bundles are usually bundled together and then stacked for storage. In the cardboard box production system, a large number of cardboard boxes need to be bundled and stacked daily. Traditionally, this was done manually, which was extremely inefficient and unsuitable for modern production needs. Currently, most companies use automated palletizing equipment to replace manual labor, making production more efficient.

[0003] Existing automated palletizing equipment mainly uses multi-axis robotic arms for automatic palletizing. Although this can reduce the labor intensity of workers and improve production efficiency, it still has the following shortcomings in actual use: First, because the multi-axis robotic arm can only pick up one bundle of cardboard at a time, the palletizing efficiency is low; second, because the multi-axis robotic arm has a small range of motion, the height of cardboard palletizing is limited, and it is not suitable for palletizing large cardboard areas.

[0020] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] like Figures 1-13As shown, a highly adaptable cardboard palletizer includes a cardboard shaping mechanism 40, a cardboard forklift mechanism 10, and a cardboard stacking mechanism 20 arranged sequentially. One side of the cardboard stacking mechanism 20 is provided with a cardboard conveying mechanism 30 for conveying pallets to a palletizing platform 22. The feeding end of the cardboard shaping mechanism 40 is also provided with a feeding conveying mechanism 50. The feeding conveying mechanism 50 includes a feeding conveying frame 51, several feeding conveying rollers 52 arranged side-by-side on the feeding conveying frame 51, and a feeding conveying motor (not shown) for driving the feeding conveying rollers 52 to rotate. The discharging end of the feeding conveying frame 51 is provided with a feeding baffle 53. In actual operation, the feeding end of the feeding conveying mechanism 50 can be connected to an upstream cardboard bundling mechanism, so that the bundled cardboard is conveyed to the cardboard shaping mechanism 40 through the feeding conveying mechanism 50.

[0023] By setting up a cardboard shaping mechanism 40, a cardboard forklift mechanism 10, and a cardboard stacking mechanism 20, the cardboard is shaped in advance according to the stacking requirements, and then forked to the stacking platform 22 of the cardboard stacking mechanism 20 by the cardboard forklift mechanism. This allows for the stacking of large-area cardboard bundles or the stacking of multiple small-area cardboard bundles side by side, improving the stacking efficiency of the cardboard. At the same time, the lifting and stacking method allows for a higher and more stable number of cardboard stacks.

[0024] like Figures 2-4 As shown, the cardboard shaping mechanism 40 includes a shaping frame 41 and a shaping conveying assembly 42, a shaping baffle 43, a first side pusher 44, and a second side pusher 45 mounted on the shaping frame 41. The shaping baffle 43 is movably mounted at the discharge end of the shaping frame 41. The first side pusher 44 and the second side pusher 45 are movably mounted between the incoming baffle 53 and the shaping baffle 43, and are arranged opposite to each other along the conveying direction perpendicular to the cardboard. The shaping conveying assembly 42 includes multiple shaping conveying rollers 421 arranged side by side and a conveying drive motor (not shown) for driving the shaping conveying rollers 421 to rotate. The lower ends of the first side pusher 44 and the second side pusher 45 are provided with arc-shaped clearance grooves 441 that are adapted to the shape of the shaping conveying rollers 421. By setting the arc-shaped clearance grooves 441, the first side pusher 44 and the second side pusher 45 can fit more closely to the shaping conveying rollers 421, and can better push the cardboard to move. It should be noted that the structure of the incoming material conveying motor driving the incoming material conveying roller 52 to rotate, and the structure of the conveying drive motor driving the shaping conveying roller 421 to rotate are both conventional technical means that are easy for those skilled in the art to think of, and will not be described in detail here.

[0025] Specifically, the upper end of the forming frame 41 is provided with two parallel side push guide rails 411. A first side push crossbeam 412 and a second side push crossbeam 413 are slidably spanned on the two side push guide rails 411. The extension directions of the first side push crossbeam 412 and the second side push crossbeam 413 are both parallel to the conveying direction of the cardboard. The forming frame 41 is provided with a first side push drive assembly 46 and a second side push drive assembly 47 that drive the first side push crossbeam 412 and the second side push crossbeam 413 to slide along the side push guide rails 411. The first side push plate 44 is installed on the first side push crossbeam 412. The first side push crossbeam 412 is provided with a first side push lifting assembly 48 that drives the first side push plate 44 to move up and down. The second side push plate 45 is installed on the second side push crossbeam 413. The second side push crossbeam 413 is provided with a second side push lifting assembly 481 that drives the second side push plate 45 to move up and down. By setting up the first side push lifting assembly 48 and the second side push lifting assembly 481, the first side push plate 44 and the second side push plate 45 can be controlled to move upward before the paperboard is conveyed. This avoids the paperboard being blocked by the first side push plate 44 and the second side push plate 45, and saves the waiting time caused by the first side push plate 44 and the second side push plate 45 resetting, thereby improving the conveying efficiency and shaping efficiency of the paperboard.

[0026] In this invention, there are two sets of the first side-push lifting assembly 48 and the second side-push lifting assembly 481. The two sets of the first side-push lifting assembly 48 are spaced apart on the first side-push crossbeam 412, and the two sets of the second side-push lifting assembly 481 are spaced apart on the second side-push crossbeam 413. The first side-push lifting assembly 48 and the second side-push lifting assembly 481 have the same structure, both including a side-push lifting cylinder 482 and a side-push lifting plate 483 whose up-and-down movement is controlled by the side-push lifting cylinder 482. The first side-push plate 44 and the second side-push plate 45 are respectively installed on the corresponding two side-push lifting plates 483. During operation, the first side-push plate 44 or the second side-push plate 45 is controlled to move up and down by controlling the side-push lifting cylinder 482 to work synchronously. The first side-push drive assembly 46 includes a first side-push motor 461, a first side-push main shaft 462 driven to rotate by the first side-push motor 461, and a first side-push drive belt 463 driven to move by the first side-push main shaft 462. The first side-push crossbeam 412 is fixedly connected to the first side-push drive belt 463 and is driven to slide along the side-push guide rail 411 by the first side-push drive belt 463. The second side-push drive assembly 47 includes a second side-push motor 471, a second side-push main shaft 472 driven to rotate by the second side-push motor 471, and a second side-push drive belt 473 driven to move by the second side-push main shaft 472. The second side-push crossbeam 413 is fixedly connected to the second side-push drive belt 473 and is driven to slide along the side-push guide rail 411 by the second side-push drive belt 473.

[0027] The discharge end of the material conveying frame 51 is provided with a material blocking cylinder 54 for driving the material blocking plate 53 to move up and down. The output shaft of the material blocking cylinder 54 is connected to the material blocking plate lifting seat 55. The material blocking plate 53 is installed on the material blocking plate lifting seat 55. The discharge end of the shaping frame 41 is provided with a shaping blocking cylinder 431 for driving the shaping plate 43 to move up and down. The output shaft of the shaping blocking cylinder 431 is connected to the shaping plate lifting seat 432. The shaping plate 43 is installed on the shaping plate lifting seat 432. During the shaping process, the first side push plate 44 is moved to a specific position according to the size of the cardboard to be stacked and the stacking requirements. Then, the shaping baffle cylinder 431 controls the shaping baffle 43 to rise and block the discharge end of the shaping frame 41. When the conveyed cardboard touches the shaping baffle 43, the second side push plate 45 pushes the cardboard to the side of the first side push plate 44 for shaping, so that the cardboard is arranged according to the required requirements. After the shaping is completed, the incoming material baffle cylinder 54 controls the incoming material baffle 53 to rise and block the discharge end of the incoming material conveyor 51. The shaping baffle cylinder 431 controls the shaping baffle 43 to descend and leave the discharge end of the shaping frame 41. Finally, the shaping conveying assembly 42 conveys the shaped cardboard to the cardboard forklift mechanism 10.

[0028] It should be understood that in practical applications, the incoming material baffle 53 and the shaping baffle 43 can also be installed by rotation, and the incoming material blocking cylinder 54 and the shaping material blocking cylinder 431 can also be replaced by a motor.

[0029] like Figures 5-6 As shown, the cardboard forklift mechanism 10 includes a forklift frame 11 and a forklift transfer assembly 12 and a forklift assembly 13 mounted on the forklift frame 11. The forklift assembly 13 includes a forklift seat 131 and a forklift drive member 132 that drives the forklift seat 131 to move toward the cardboard stacking mechanism 20. The forklift seat 131 is provided with a plurality of parallel and spaced forklift arms 133. The forklift transfer assembly 12 includes a conveyor belt 121 for conveying the cardboard output from the cardboard shaping mechanism 40 to the forklift arms 133 and a forklift transfer drive member 122 that drives the conveyor belt 121 to move. The conveyor belt 121 is provided in multiple sets, which are distributed in parallel and spaced apart, and can move up and down relative to the forklift arms 133.

[0030] Specifically, the forklift conveying assembly 12 further includes a forklift conveying bracket 123, which is movably mounted on the forklift frame 11. The forklift frame 11 is provided with a conveying lifting drive component 124 that drives the forklift conveying bracket 123 to move up and down. The conveyor belt 121 and the forklift conveying drive component 122 are both mounted on the forklift conveying bracket 123. The conveying lifting drive component 124 is a conveying lifting cylinder, and multiple conveying lifting cylinders are provided. The forklift conveying bracket 123 is provided with a vertical guide rod 125, and the forklift frame 11 is provided with a guide sleeve 126 that is adapted to the guide rod 125. The guide rod 125 and the guide sleeve 126 are slidably connected. When paperboard needs to be transferred, multiple transfer lifting cylinders, under the control of the control system, simultaneously control the forklift transfer bracket 123 to rise, making the conveyor belt 121 higher than the forklift arm 133. At this time, the paperboard is conveyed from the paperboard shaping mechanism 40 onto the conveyor belt 121, which then transports the paperboard above the forklift arm 133. Then, under the control of the control system, the multiple transfer lifting cylinders simultaneously control the forklift transfer bracket 123 to descend, making the conveyor belt 121 lower than the forklift arm 133, allowing the paperboard to fall onto the forklift arm 133. At this point, the forklift drive 132, through the forklift seat 131, causes the forklift arm 133 to drive the paperboard towards the paperboard stacking mechanism 20. In practical applications, electric cylinders can also be used instead of transfer lifting cylinders. It should be noted that the synchronous control of multiple cylinders is a mature technology in this field and is not an innovation of this application. The specific control method and principle will not be described in detail here.

[0031] In this invention, the forklift drive 122 is a forklift motor, and the output shaft of the forklift motor is connected to the forklift main shaft 127 via a synchronous belt. Multiple conveyor belts 121 are driven synchronously by the forklift main shaft 127. The forklift arms 133 and the conveyor belts 121 are distributed alternately.

[0032] Specifically, the forklift frame 11 is provided with a forklift slide rail 111, the forklift seat 131 is slidably mounted on the forklift slide rail 111, the forklift drive component 132 is a forklift drive motor, the output shaft of the forklift drive motor is driven and connected to the forklift main shaft 134 via a synchronous belt, the two ends of the forklift main shaft 134 are provided with forklift drive belts 135, the two ends of the forklift seat 131 are respectively fixedly connected to the corresponding forklift drive belts 135, and the extension direction of the forklift slide rail 111 is parallel to the forklift drive belts 135. The forklift frame 11 is provided with a fork arm support seat 112 at one end near the cardboard stacking mechanism 20, the top of the fork arm support seat 112 is provided with a support roller 113, one end of the forklift arm 133 is fixedly connected to the forklift seat 131, and the cantilever end of the forklift arm 133 overlaps the upper side of the support roller 113. The forklift arm 133 is provided with a forklift guide ramp 136 at the material receiving end, which facilitates the smooth conveying of the shaped cardboard onto the forklift arm 133 and avoids jamming.

[0033] like Figures 7-11 As shown, the cardboard stacking mechanism 20 includes a stacking frame 21 and a stacking platform 22 disposed on the stacking frame 21, a stacking lifting drive 23 that drives the stacking platform 22 to move up and down, and a front stacking baffle 24 and a rear stacking baffle 25 that cooperate with the forklift arm 133 to stack cardboard on the stacking platform 22. The front stacking baffle 24 and the rear stacking baffle 25 are both comb-shaped, so that when the front stacking baffle 24 and the rear stacking baffle 25 move downward, they can pass through the forklift arm 133 and only block and position the cardboard on the forklift arm 133.

[0034] Specifically, the stacking lifting drive 23 is a stacking lifting motor. The output shaft of the stacking lifting motor is connected to a stacking lifting main shaft 231. Both ends of the stacking lifting main shaft 231 are connected to stacking lifting secondary shafts 233 extending in the same direction via right-angle steering reducers 232. Each of the two stacking lifting secondary shafts 233 is equipped with a stacking lifting gear 234. A stacking lifting chain 235 meshes with the stacking lifting gear 234. One end of the stacking lifting chain 235 is connected to the palletizing platform 22, and the other end of the stacking lifting chain 235 passes upward around the stacking lifting gear 234 and is connected downward to a counterweight 236. By setting the counterweight 236, the force on both ends of the stacking lifting chain 235 is more even, which facilitates the lifting control of the palletizing platform 22.

[0035] In this invention, the stacking frame 21 is provided with a platform lifting guide rail 215 for guiding the lifting and lowering of the palletizing platform 22. The platform lifting guide rail 215 has a T-shaped cross-section.

[0039] Before the cardboard is forked, the front drive assembly 26 controls the stacking front baffle 24 to move to the discharge end of the forklift frame 11. Then, the stacking front baffle drive 28 controls the stacking front baffle 24 to move downward, thereby pre-positioning the cardboard conveyed by the forklift conveying assembly 12 until the cardboard is transferred to the forklift arm 133. Then, the stacking front baffle drive 28 controls the stacking front baffle 24 to move upward. Next, the rear drive assembly 27 controls the stacking rear baffle 25 to move to a specific position along the baffle lateral slide rail 214 according to the size of the cardboard to be stacked. The stacking rear baffle drive 29 controls the stacking rear baffle 25 to move downward, blocking the rear end of the cardboard forked by the forklift arm 133. When the cardboard is forked above the stacking platform 22, the stacking... The front stacking drive 28 controls the front stacking baffle 24 to move downwards, blocking the front end of the cardboard. Then, the front drive assembly 26 controls the front stacking baffle 24 to move towards the rear stacking baffle 25, so that the front stacking baffle 24 and the rear stacking baffle 25 abut against the front and rear ends of the cardboard, respectively. Finally, the forklift drive 132 uses the forklift seat 131 to reset the forklift arm 133 away from the cardboard stacking mechanism 20. At this time, the cardboard is released from the forklift arm 133 under the limitation of the front stacking baffle 24 and the rear stacking baffle 25 and falls onto the stacking platform 22, thus completing the stacking of one layer of cardboard. Then, the stacking lifting drive 23 controls the stacking platform 22 to descend one layer, waiting for the next layer of cardboard to be stacked. In order to facilitate the transfer and storage of cardboard, a pallet is placed on the stacking platform 22 before stacking, so that the cardboard is stacked on the pallet 100, which makes it easy to transport the stacked cardboard by forklift.

Pallet ejection gears are fixed at both ends of the pallet ejection main shaft 222. Pallet ejection chains 223 are meshed on the pallet ejection gears. Pallet ejection crossbars 224 are provided on the two pallet ejection chains 223. One end of the pallet ejection chain 223 near the material discharge end of the palletizing platform 22 extends out of the outer side of the palletizing platform 22. During stacking, the pallet ejection crossbars 224 rotate with the pallet ejection chains 223 under the control of the pallet ejection motor 221 to the bottom of the palletizing platform 22. After stacking is completed, the pallet ejection crossbars 224 rotate to the top of the front end of the palletizing platform 22 and push the pallets stacked on the cardboard from the palletizing platform 22 from front to back. By extending the pallet ejection chain 223 beyond the palletizing platform 22, the cardboard on the pallet can be completely detached from the palletizing platform 22 after the pallet is ejected, thus preventing the cardboard on the pallet from being overturned when the palletizing platform 22 rises.

[0043] like Figures 12-13 As shown, the pallet conveying mechanism 30 includes a pallet pushing platform 31 and a pallet pushing motor 32 mounted on the pallet pushing platform 31. The pallet pushing platform 31 has parallel pallet pushing guide rails 33, and a pushing connecting plate 34 is slidably mounted on the pallet pushing guide rails 33. The pushing connecting plate 34 extends from front to back, and a pallet pushing crossbar 35 is mounted at the extended end of the pushing connecting plate 34. The output shaft of the pallet pushing motor 32 is driven and connected to a pallet pushing main shaft 36 via a synchronous belt. Pallet pushing belts 37 are driven and connected to both ends of the pallet pushing main shaft 36. The pushing connecting plate 34 is fixedly connected to the pallet pushing belts 37 and is driven by the pallet pushing belts 37 to move along the pallet pushing guide rails 33. A pushing cover 38 is provided outside the pallet pushing motor 32 and the pallet pushing main shaft 36.

[0044] In this embodiment, when the cardboard area is small, it can be stacked simultaneously on two smaller pallets 100, such as... Figure 14 As shown, when the cardboard area is large, the cardboard can be stacked on a large pallet 100, or multiple small cardboard pieces can be stacked side by side on a large pallet 100.

[0045] In summary, this invention, by setting up a cardboard shaping mechanism, a cardboard forklift mechanism, and a cardboard stacking mechanism, enables the cardboard to be shaped in advance according to the stacking requirements, and then forked to the stacking platform of the cardboard stacking mechanism by the cardboard forklift mechanism. This allows for the stacking of large-area cardboard bundles, as well as the side-by-side stacking of multiple small-area cardboard bundles, greatly improving the flexibility of stacking. At the same time, the lifting and stacking method allows for higher and more stable cardboard stacking layers.
