Description
Technical Field
[0001] This utility model relates to the field of anti-tipping devices, specifically to an anti-tipping structure for a vertical box opener used for rice packaging boxes. Background Technology
[0002] Existing vertical carton erecting machines use manual pushing or tilting of the loading mechanism to transport cartons to the machine's feed inlet by gravity. While these methods can achieve the purpose of transportation, when the robotic arm inside the machine picks up and grips the cartons, it causes impacts that are directly transmitted to the cartons behind. These impacts can cause the cardboard to shake or shift, leading to the cartons losing their vertical position and tipping over. Utility Model Content

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments and features of this utility model can be combined with each other.
[0026] The following description sets forth many specific details to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments described in the specification are only some embodiments of the present invention, and not all embodiments.
[0027] Combination Figures 1 to 6As shown in the figure, the anti-tipping structure of the vertical carton opener for rice packaging boxes provided in this embodiment of the utility model includes a carton opener body 1, an upper carton mechanism 2 at the feed inlet of the carton opener body 1, an upper carton frame 21, a carton to be opened vertically arranged on the upper carton frame 21, a first sector-shaped stop 211 on the upper carton frame 21, the first sector-shaped stop 211 having a sector-shaped cross-section, a support plate 3 that slides along the length direction on the upper carton frame 21, the support plate 3 being in contact with the outermost carton to be opened, the support plate 3 driving the carton to be opened along the direction from the feed inlet of the upper carton frame 21 to the feed inlet of the carton opener body 1, and an installation frame 4 installed on the upper carton frame 21, the upper end of the installation frame 4 having a second sector-shaped stop structure 43, the second sector-shaped stop 43 being vertically aligned with the first sector-shaped stop 211, the second sector-shaped stop 43 and the first sector-shaped stop 211 being vertically aligned ... The structure of the first sector-shaped block 211 is the same. One side of the first sector-shaped block 211 is an arc surface and the other side is a vertical cut surface. The vertical cut surface of the second sector-shaped block 43 and the first sector-shaped block 211 is in contact with one side of the innermost carton to be opened. The second sector-shaped block 43, the first sector-shaped block 211 and the support plate 3 form an anti-tipping component. When the mechanical arm in the carton opener body 1 picks up the innermost carton to be opened, the vertical cut surface of the second sector-shaped block 43 and the first sector-shaped block 211 abuts against the innermost carton to be opened. After the innermost carton to be opened enters the carton opener body 1, the support plate 3 drives the remaining carton to be opened. The newly formed innermost carton to be opened is squeezed through the arc surface of the second sector-shaped block 43 and the first sector-shaped block 211, and one side of it is in contact with the vertical cut surface of the second sector-shaped block 43 and the first sector-shaped block 211.
[0028] The upper box frame 21 has a gap in the middle of its bottom surface to reduce friction when the cardboard moves. The box opener body 1 has a control console 11 on one side, which is electrically connected to the box opener body 1.
[0029] Therefore, the anti-tipping component prevents the innermost carton from shaking and tipping over when it is gripped by the mechanical arm inside the carton opener body 1. This solves the problem that the impact would cause the cardboard to shake or shift, which would cause the carton to lose its vertical position and tip over.
[0030] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the upper box mechanism 2 also includes a first slide groove 212, which is longitudinally opened on the upper box frame 21 along the width, a first spring assembly 213, one end of which is fixedly connected to the first slide groove 212, and the other end of which is fixedly connected to the first sector-shaped stop 211. The first sector-shaped stop 211 elastically slides in the first slide groove 212. The mounting frame 4 also includes a second slide groove 41, which is longitudinally opened on the mounting frame 4 along the width, a second spring assembly 42, one end of which is fixedly connected to the second slide groove 41, and the other end of which is fixedly connected to the second sector-shaped stop 43. The second sector-shaped stop 43 elastically slides in the second slide groove 41.
[0031] Therefore, the carton to be opened is vertically installed on the upper carton platform 21. At this time, the support plate drive mechanism 7 is driven until one side of the innermost carton to be opened is in contact with the vertical cut surface of the second sector block 43 and the first sector block 211. Then, the mechanical arm of the carton opener body 1 is activated to suction and grab the carton to be opened. Since the vertical cut surface of the second sector block 43 and the first sector block 211 cannot directly squeeze it laterally and compress it into the slot, the impact generated during the grabbing process is blocked by the vertical cut surface of the second sector block 43 and the first sector block 211. After the grabbing is completed, the support plate 3 is driven again, so that the newly formed innermost carton to be opened is squeezed through the arc surface of the second sector block 43 and the first sector block 211, so that one side of it is in contact with the vertical cut surface of the second sector block 43 and the first sector block 211, replacing the previous carton.
[0032] In some embodiments, such as Figure 2 As shown, it also includes a support plate drive mechanism 7, which is installed on both sides of the upper box frame 21. The support plate drive mechanism 7 includes two low-frequency motors 71, which are fixedly connected to the left and right sides of the upper box frame 21 near the box opening machine body 1. The output end of the low-frequency motor 71 is fixedly connected to a screw 72. Connecting blocks are fixedly assembled on the left and right sides of the upper box frame 21 away from the box opening machine body 1. The connecting blocks are rotatably connected to the screw 72. A slider 73 is threadedly connected to the screw 72. The side wall of the slider 73 is in contact with the side wall of the upper box frame 21. A connecting rod is fixedly connected to the upper end of the slider 73. The connecting rod is fixedly connected to the support plate 3.
[0033] Thus, the carton to be opened is vertically installed on the upper platform 21. At this time, the slow motor 71 is turned on, which drives the screw 72 to rotate and causes the support plate 3 on the slider 73 to slide until the innermost side of the carton to be opened is in contact with the vertical cut surface of the second sector block 43 and the first sector block 211.
[0034] In some embodiments, such as Figure 2 and Figure 6As shown, an auxiliary fixing mechanism 8 is installed at one end of the upper box frame 21 near the box opener body 1. The auxiliary fixing mechanism 8 includes a third slide 81, which is opened laterally along the width on the upper surface of the upper box frame 21 near the box opener body 1, and a third spring assembly 82, one end of which is fixedly connected to the third slide 81. The other end of the third spring assembly 82 is fixedly connected to an arc-shaped stop 83. The arc-shaped stop 83 slides elastically in the third slide 81 and is in contact with the other side of the innermost carton to be opened.
[0035] The third spring group 82 consists of at least four springs that are evenly installed.
[0036] Therefore, the carton to be opened is vertically installed on the upper carton platform 21. At this time, the support plate drive mechanism 7 is driven until one side of the innermost carton to be opened is in contact with the vertical cut surface of the second sector block 43 and the first sector block 211. Then, the mechanical arm of the carton opener body 1 is activated to suction and grab the carton to be opened. Since the vertical cut surface of the second sector block 43 and the first sector block 211 cannot directly squeeze it laterally and compress it into the slot, the impact generated during the grabbing process is blocked by the vertical cut surface of the second sector block 43 and the first sector block 211. After the grabbing is completed, the support plate 3 is driven again, so that the newly formed innermost carton to be opened is squeezed through the arc surface of the second sector block 43 and the first sector block 211, so that one side of it is in contact with the vertical cut surface of the second sector block 43 and the first sector block 211, replacing the previous carton.
[0037] In some embodiments, such as Figure 1 and Figure 5 As shown, the carton ejector body 1 has a carton ejection platform 5 at its discharge port. A carton feeding roller assembly 51 is rotatably connected to the carton ejection platform 5. The carton after ejection is moved to the outside via the carton feeding roller assembly 51. A correction mechanism 6 is provided on both sides of the carton ejection platform 5. The correction mechanism 6 includes a cylinder 61, which is symmetrically installed on both sides of the carton ejection platform 5 near the discharge port. A connecting frame 62 is fixedly connected to the output end of the cylinder 61. The cylinder 61 drives the connecting frame 62 laterally. A correction roller 63 is rotatably connected inside the connecting frame 62. After the correction roller 63 moves, it rolls and adheres to the side wall of the carton after ejection. The carton after adhering is located on the center line of the carton ejection platform 5.
[0038] Therefore, after the carton is opened, it is transported to the carton delivery platform 5. At this time, the cylinder 61 is activated to push out the correction roller 63. The two correction rollers 63 are driven synchronously to make the carton located in the middle of the carton delivery roller group 51, preventing deviation during the conveying process. Deviation would also cause the carton to tip over. The whole device achieves the goal of preventing the impact generated when the innermost carton to be opened is picked up by the mechanical arm in the carton opener body, thus preventing the remaining carton from shaking and tipping over.
[0039] The following is in conjunction with the appendix Figure 1-6 A specific embodiment of this utility model is described below:
[0040] like Figures 1-6 As shown, the device includes a carton opener body 1, an upper carton mechanism 2 at the feed inlet of the carton opener body 1, an upper carton frame 21, a carton to be opened vertically mounted on the upper carton frame 21, a first sector-shaped stop 211 on the upper carton frame 21 with a sector-shaped cross-section, a support plate 3 that slides along the length of the upper carton frame 21, the support plate 3 being in contact with the outermost carton to be opened, and the support plate 3 driving the carton to be opened along the direction from the feed inlet of the upper carton frame 21 to the feed inlet of the carton opener body 1, and a mounting frame 4 mounted on the upper carton frame 21. The upper end of the mounting frame 4 is provided with a second sector-shaped stop structure 43, the second sector-shaped stop 43 being vertically aligned with the first sector-shaped stop 211, and the second sector-shaped stop 43 having the same structure as the first sector-shaped stop 211. One side of the fan-shaped stop 211 is an arc surface, and the other side is a vertical cut surface. The vertical cut surfaces of the second fan-shaped stop 43 and the first fan-shaped stop 211 are in contact with one side of the innermost carton to be opened. The second fan-shaped stop 43, the first fan-shaped stop 211, and the support plate 3 form an anti-tipping component. When the robotic arm inside the carton opener body 1 picks up the innermost carton to be opened, the vertical cut surfaces of the second fan-shaped stop 43 and the first fan-shaped stop 211 press against the innermost carton to be opened. After the innermost carton to be opened enters the carton opener body 1, the support plate 3 drives the remaining carton to be opened. The newly formed innermost carton to be opened is squeezed through the arc surface of the second fan-shaped stop 43 and the first fan-shaped stop 211, and one side of it is in contact with the vertical cut surface of the second fan-shaped stop 43 and the first fan-shaped stop 211.
[0041] In actual use, the carton to be opened is vertically installed on the upper platform 21. The slow-speed motor 71 is then turned on, driving the screw 72 to rotate, which in turn causes the support plate 3 on the slider 73 to slide until one side of the innermost carton to be opened is in contact with the vertical cut surfaces of the second sector-shaped block 43 and the first sector-shaped block 211, and the other side is in contact with the arc-shaped block 83 and the fixed rod of the carton opener body 1. At this point, the robotic arm of the carton opener body 1 is activated to grip and grasp the carton to be opened. Because the vertical cut surfaces of the second sector-shaped block 43 and the first sector-shaped block 211 cannot directly compress the carton laterally into the slot, the impact generated during the grasping process is blocked by the vertical cut surfaces of the second sector-shaped block 43 and the first sector-shaped block 211, preventing the carton behind it from vibrating and tipping over. The robotic arm then pulls the carton through... After the carton is gripped by the fixed rod of the carton erector body 1 and the arc-shaped stop 83, the support plate 3 continues to drive the newly formed innermost carton to be opened, so that the innermost carton to be opened is squeezed through the arc surface of the second sector-shaped stop 43 and the first sector-shaped stop 211, so that one side of it is in contact with the vertical cut surface of the second sector-shaped stop 43 and the first sector-shaped stop 211, replacing the previous carton. After the carton is opened, the carton is transported to the carton output table 5. At this time, the cylinder 61 is activated to push out the correction roller 63. The two correction rollers 63 are driven synchronously to make the carton located in the middle of the carton feeding roller group 51, preventing deviation during the conveying process. Deviation will also cause the carton to tip over. The whole device realizes that the impact generated when the innermost carton to be opened is gripped by the mechanical arm in the carton erector body will prevent the remaining carton from shaking and tipping over.
