Detailed Implementation
[0019] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0020] See Figure 1-4 This embodiment relates to an automatic stacking device for cardboard boxes 110, including a frame 100 and a conveyor 1 for conveying cardboard boxes 110, which is inclined at a certain angle and rotatably equipped with several sets of rollers 11. A vision inspection component 2 for inspecting the appearance of cardboard boxes 110 is also provided on the conveyor 100 along the conveying end direction of the conveyor 1 and positioned on one side of the vision inspection component 2. A stacking component 3 for stacking and piling cardboard boxes 110 is provided on the frame 100 along the conveying end direction of the conveyor 1. The stacking component 3 includes a fixed base 31 provided on the frame 100 and a cylinder 3 provided on the fixed base 31. The support frame 32, which is driven to slide up and down at the end of the conveyor 1, and the second conveyor 33, which is formed by a number of second rollers 331 rotatably arranged on the support frame 32, are provided at the end of the second conveyor 33. The stop 35, which is driven to slide up and down by the second cylinder 34, is provided at the end of the conveyor 33. The frame 100, which is placed above the support frame 32, is provided with a stacking frame 4 for stacking cartons 110. The bottom two sides of the stacking frame 4 are also rotatably provided with baffles 41. The stacking frame 4 at the two ends below the baffles 41 is also provided with blocks 42.
[0021] Specifically in this embodiment, such as Figure 1 The overall structure of this automatic stacking device for cartons 110, as shown, allows for the sequential transport of cartons 110 after batch packaging via a conveyor 1 mounted on the frame 100. The conveyor 1 can also be connected to a conveyor line on an automatic packaging line for the corresponding cartons 110, depending on usage requirements. The conveyor 1, tilted at a certain angle, ensures that the cartons 110 placed on it are pre-positioned along its transport direction by several sets of rollers 11 mounted on the conveyor 1. Figure 2After the visual inspection component 2, as shown, performs visual inspection such as appearance inspection, the cardboard box 110 arrives at the stacking component 3 located at the end of the conveyor belt 1 on the frame 100. When the cardboard box 110 is on the second conveyor belt 33 via several sets of second rollers 331, it moves from... Figure 4 As can be seen, the stop 35 located at the end of the second conveyor 33 can be used to adapt and stop the carton 110 placed on the second conveyor 33 under the push of the second cylinder 34. Specifically, the second cylinder 34 can push the stop 35 to move up and down according to the detection structure of the vision inspection component 2. That is, when the carton 110 on the second conveyor 33 passes the inspection of the vision inspection component 2 on the conveyor 1, it can be seen that... Figure 3As shown, the second cylinder 34 drives the stop 35 to move upward and block the carton 110. At the same time, the cylinder 311 works to push the support frame 32 and the second conveyor 33 on it, as well as the carton 110 on the second conveyor 33, upward along the stacking frame 4 set at the corresponding position above the frame 100. During the rising of the carton 110, the two sets of baffles 41 structures rotatably set on the bottom two sides of the stacking frame 4 can contact the two sides of the carton 110 and rotate upward to the corresponding angle as the carton 110 rises. Then, under the push of the cylinder 311, the carton 110 is completely placed inside the stacking frame 4 and the bottom of the carton 110 separates from the baffles 41 rotatably set on the bottom two sides of the stacking frame 4. The baffles 41 can automatically rotate and return to the initial position under the blocking of the lower stop 42. When the cylinder 311 operates, it drives the support frame 32 and the second conveyor 33 on it to move downward and return to the initial position. During the descent of the carton 110 on the second conveyor 33, the two sets of baffles 41 on both sides of the bottom frame of the stacking frame 4 rotate back to the initial position to block the two sides of the carton 110 and place the carton 110 on the bottom two sides of the stacking frame 4. This process is repeated to realize the sequential stacking and stacking of the carton 110 on the second conveyor 33 within the stacking frame 4. Conversely, when the carton 110 on the second conveyor 33 is detected by the visual inspection component 2 on the conveyor 1 and a carton 110 that fails the inspection is detected, the second cylinder 34 drives the stop 35 to move downward to facilitate the operator to remove the corresponding carton 110 and carry out subsequent processing. This automatic carton stacking device 110, through the corresponding structural settings of the conveyor 1, vision inspection component 2, and stacking component 3 on its frame 100, has a certain working efficiency while having a compact and simple overall structure. It is easy to operate and, compared with traditional robotic arms, can effectively improve the utilization rate of operating space to a certain extent. It can meet different usage environments and effectively reduce usage costs. It has high applicability and structural adaptability. In addition, it can appropriately reduce unnecessary movement of the carton 110 during operation, effectively shorten the operating distance of the carton 110 during the stacking process, and also effectively reduce unnecessary damage and deformation to the surface of the carton 110 during the stacking process, further improving the stability and efficiency of the carton 110 stacking.In addition, this automatic cardboard box stacking device can also perform real-time visual inspection of the appearance of the cardboard boxes 110 before stacking, under the detection of the visual inspection component 2. This inspection checks whether the packaging parameters such as the specifications, labels, or specific types and quantities of internal items pasted or printed on the outside of the cardboard boxes 110 are accurate or their positions are accurate, depending on the packaging requirements. Combined with the stop 35 on the second conveyor 33 of the stacking component 3, which is driven up and down by the second cylinder 34, it is convenient for operators to remove unqualified cardboard boxes 110 and perform other subsequent operations. This further improves the functional versatility of this automatic cardboard box stacking device and the overall packaging effect and quality of the cardboard boxes 110, meets different packaging requirements, effectively improves the uniformity of the packaging quality of the batch of cardboard boxes 110 after stacking and the safety of the batch of cardboard boxes 110 during transportation, and improves after-sales quality.
[0022] Several sets of rollers 11 rotatably mounted on the conveyor 1 are distributed at both ends of the conveyor 1 with gaps. The visual inspection component 2 includes multiple sets of visual inspection probes 21 mounted on the frame 100 via mounting brackets 20, respectively positioned above the conveyor 1 on both sides and below the gaps. The visual inspection probes 21 are mounted on the mounting brackets 20 at corresponding positions via connecting seats 22 hinged to them. Specifically, from... Figure 2 As can be seen, the arrangement of multiple sets of visual inspection probes 21 at corresponding positions on the conveyor 1 and mounting frame 20 using this structure can further expand the detection range of the carton 110 as it moves on the conveyor 1, improve the comprehensiveness of the detection by the multiple sets of visual inspection probes 21, and enhance the detection effect and accuracy of this visual inspection component 2. Simultaneously, during detection, the multiple sets of visual inspection probes 21 mounted on the mounting frame 20 via the connecting seat 22 can also rotate at a certain angle on the connecting seat 22 to ensure that the visual inspection probes 21 have the optimal detection angle, facilitating installation, disassembly, and adjustment, and improving operational convenience and flexibility.
[0023] The second conveyor 33 is rotatably mounted on the support frame 32 via a fixed frame 332 at its bottom. The second conveyor 33 is tilted at an appropriate angle along the end of the conveyor 1 by a stop bar 101 located at a corresponding position on the frame 100. The support frame 32 has a second stop bar 321 at an appropriate height located at the top below the stop bar 101 on the frame 100. See details for further information. Figure 1 and Figure 3 The second conveyor channel 33, which is rotatably mounted on the support frame 32 shown, is in the corresponding state under the push of the cylinder 311. The second conveyor channel 33 on the support frame 32 is located in Figure 1In the initial position shown, the fixing bracket 332 at its bottom can abut against the stop bar 101 at the corresponding position on the frame 100, allowing the second conveyor 33 to adapt to the same tilt angle as the conveyor 1 on the frame 100. This further improves the smoothness and efficiency of the carton 110's transport from the conveyor 1 to the second conveyor 33. Simultaneously, the up-and-down movement of the stop block 35 driven by the second cylinder 34 on the second conveyor 33 facilitates subsequent processing such as the discharge of cartons 110 with substandard packaging quality. Furthermore, for cartons 110 that have passed the inspection by the vision inspection component 2 on the second conveyor 33, during the upward movement driven by the cylinder 311, see... Figure 3 As shown, the second conveyor 33 on the support frame 32 can rotate at an appropriate angle under the action of gravity through the fixed frame 332 at its bottom. Subsequently, it abuts against the second stop bar 321 at the corresponding position on the top of the support frame 32 and separates from the stop bar 101 on the frame 100. At this time, the second conveyor 33 on the support frame 32 can maintain a horizontal state so as to carry out the subsequent stacking process of carton 110 in the stacking frame 4 above the frame 100. After the carton 110 is stacked, the support frame 32 returns to the initial position under the drive of the cylinder 311. The second conveyor 33 on it continues to maintain the same tilt angle as the conveyor 1 so as to facilitate the normal conveying process of the next carton 110. This further improves the conveying effect and conveying stability of the conveyor 1 and the second conveyor 33 on the frame 100 and reduces the phenomenon of carton 110 getting stuck during the conveying process.
[0024] The stop 35 is also rotatably equipped with multiple sets of third rollers 351, from Figure 3 or Figure 4 As can be seen, when the baffle 35 with this structure is used to discharge the carton 110 with unqualified packaging quality, the multiple sets of third rollers 351 mounted on it can play a certain guiding role, further improving the convenience and efficiency of the carton 110 discharge and removal process.
[0025] The frame 100 is further provided with a second frame 5, which is located at the end of the second conveyor 33. The second frame 5 is provided with a second stacking frame 51 for stacking cartons. Figure 1 As can be seen, the addition of the second frame 5 and the second stacking frame 51 on it facilitates the unified collection and subsequent processing of unqualified cartons 110 on the second conveyor 33 during the rejection process, further improving the continuity and efficiency of the entire workflow of this automatic carton 110 stacking device for conveying, detecting, rejecting and stacking cartons 110, and meeting different usage needs.
[0026] The second stacking frame 51 is further equipped with a lifting assembly 6. The lifting assembly 6 includes a second fixed seat 61 built into the second stacking frame 51 below the second conveyor 33. A support plate 62 is provided above the second fixed seat 61. The support plate 62 is driven to slide up and down by multiple sets of connecting rods 621 provided at its bottom and a third cylinder 611 connected to the second fixed seat 61. An opening is provided on one side of the frame of the second stacking frame 51 above the second fixed seat 61. Specifically, from... Figure 1 and Figure 5 As can be seen, the support plate 62 can move up and down above the second fixed seat 61 within the second stacking frame 51 under the drive of the third cylinder 611 mounted on the second fixed seat 61. This allows the defective cartons 110 rejected on the second conveyor channel 33 to be stored on the support plate 62. To ensure optimal stacking, the maximum stroke of the third cylinder 611 on the second fixed seat 61 is set such that the highest point of the support plate 62 driven by it is lower than the end of the second conveyor channel 33. This facilitates the stacking of cartons 110 on the support plate 62 under the drive of the third cylinder 611. Furthermore, individual cartons 110 can be stacked through the adaptable opening on one side of the second stacking frame 51. The addition of the lifting component 6 inside the second stacking frame 51 during the removal of carton 110 further enhances the functionality of this automatic carton 110 stacking device, effectively improving the stacking effect of the carton 110 inside, and effectively reducing the impact caused by the impact of the carton 110 inside the second stacking frame 51 during the stacking process, thus preventing unnecessary damage and deformation of the carton 110. Furthermore, in conjunction with the sliding connection process of multiple sets of connecting rods 621 at the bottom of the support plate 62 to the second fixed seat 61, the stability and load-bearing capacity of the support plate 62 during the up-and-down movement can be further improved, reducing unnecessary positional displacement of the carton 110 during the stacking process, and improving the stacking effect and stacking stability of the carton 110.
