Description

Technical Field

[0001] This utility model relates to the field of box sealing technology, and in particular to a box sealing device. Background Technology

[0002] In related technologies, to ensure the safety of goods, some items are stored in packaging boxes for turnover and transportation. This serves to distinguish them from other items, prevent damage from compression, and also prevent loss during transportation and sorting. When sealing the boxes, manual sealing is usually used. The general process involves closing the lid, attaching the two side latches, and affixing the box barcode. Because some packaging box lids (such as those with a corrugated interlocking design) require high precision when closing, the process involves many steps, resulting in long manual operation times. Furthermore, the sealing pressure is even greater when multiple boxes are cleared at once, requiring an immediate increase in sealing manpower. However, manual sealing is greatly affected by human factors, has low efficiency, and carries the risk of exceeding the stipulated working time. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a box-sealing device that can achieve mechanized box sealing, thereby improving sealing efficiency.

[0004] According to a first aspect of the present invention, a box sealing device is used to seal a packaging box, the packaging box including a box body with an upward opening, a cover for sealing the opening of the box body, and a latch for locking the cover and the box body; the box sealing device includes: a frame; a conveying device, the conveying device being disposed on the frame, including a conveying mechanism and a carrying mechanism connected to the conveying mechanism, the carrying mechanism being used to carry the packaging box, and the conveying mechanism being used to drive the carrying mechanism to convey the packaging box along a first direction; a guide rod, the guide rod being connected to the frame, the guide rod including a first section and a second section connected to each other, the first section and the second section being connected to each other. The second segment is arranged sequentially along the first direction. The first segment is inclined upward along the first direction, and the second segment extends along the first direction and is inclined towards the bearing mechanism. The first segment and the second segment are used to abut against the cover to drive the cover to flip towards the opening during the process of the packaging box along the first direction. A capping device is arranged downstream of the guide rod along the first direction. The capping device includes a pressing head, which is arranged above the conveying mechanism along a second direction. The pressing head can move along the second direction for pressing the cover. The second direction is a vertical direction.

[0005] According to the first aspect of the present invention, the sealing device has at least the following beneficial effects: the lid of the packaging box is opened to allow items to be placed inside the packaging box. After the items are placed, the conveying device conveys the packaging box to the position of the guide rod. As the packaging box passes the guide rod, the guide rod guides the lid to flip and cover the opening of the box. The first section is used to abut the lid to drive the lid to flip upward, and the second section is used to abut the lid to drive the lid to flip toward the opening. Therefore, as the packaging box is conveyed along the first direction through the guide rod, the lid contacts the first section. Under the abutting and guiding action of the first section, the lid flips upward. The packaging box continues to be conveyed along the first direction, causing the lid to contact the second section. Under the abutting action of the second section, the lid flips toward the opening of the box, thereby at least partially covering the opening. Then, the lid is pressed by the pressing device, thereby locking the lid onto the opening of the box.

[0006] According to some embodiments of the present invention, the sealing device includes two guide rods, namely a left rod and a right rod, which are respectively arranged on both sides of the conveying path of the packaging box.

[0007] According to some embodiments of the present invention, the end of the first segment away from the second segment is lower than the bearing surface of the bearing mechanism along a second direction; and / or, the second segment is inclined downward along the first direction.

[0008] According to some embodiments of this utility model, the left rod and the right rod are symmetrically arranged on both sides of the conveying path of the packaging box so that the cover flips synchronously.

[0009] According to some embodiments of the present invention, a first gap is provided between the first segment of the left rod and the first segment of the right rod to allow the packaging box to pass between the left rod and the right rod, and a second gap is provided between at least a portion of the second segment of the left rod and the second segment of the right rod, the second gap being smaller than the first gap.

[0010] According to some embodiments of the present invention, the sealing device further includes a first scanning device and a second scanning device. The first scanning device is disposed upstream of the guide rod along the first direction and is used to scan the information of the packaging box. The second scanning device is disposed upstream of the guide rod along the first direction and is used to scan the information of the items inside the packaging box.

[0011] According to some embodiments of the present invention, the carton sealing device further includes a labeling device, which is disposed downstream of the capping device along the first direction, and is used to apply a label to the carton.

[0012] According to some embodiments of the present invention, the sealing device further includes an information processing device. The first scanning device, the second scanning device, and the labeling device are all signal-connected to the information processing device. The information processing device is used to generate printing information based on the information of the packaging box and / or the information of the items inside the packaging box. The labeling device is also used to print the label based on the printing information.

[0013] According to some embodiments of the present invention, the sealing equipment further includes a visual inspection device, which is disposed downstream of the capping device and is used to inspect the appearance of the packaging box.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The sealing device in the first embodiment of this utility model is used to seal a packaging box 1. The packaging box 1 includes a box body 11 with an opening, a cover 12 covering the opening of the box body 11, and a latch for locking the cover 12 and the box body 11. The cover 12 is rotatably mounted on the box body 11, and the cover 12 can be flipped relative to the box body 11 to open or cover the opening of the box body 11. The rotation axis of the cover 12 during flipping is set along the edge of the opening. (See reference...) Figure 4 , Figure 5 and Figure 6During the flipping process of the lid 12, there are a first position, a second position, and a third position. The packaging box 1 corresponding to the first, second, and third positions of the lid 12 has a first state, a second state, and a third state. When the lid 12 is in the first position, the angle between the plane of the opening of the box 11 and the plane of the lid 12 itself is not less than 90°, so that the opening of the box 11 can be fully opened to avoid the lid 12 blocking the opening. At this time, it is more convenient to put items into the box 11.

[0031] The sealing equipment includes: a frame 2, a conveying device 3, a guide rod 4, and a capping device 5. The conveying device 3 is mounted on the frame 2 and includes a conveying mechanism and a carrying mechanism connected to the conveying mechanism. The carrying mechanism carries the packaging box 1, and the conveying mechanism drives the carrying mechanism to convey the packaging box 1 along a first direction. Placing the packaging box 1 in its first state on the carrying mechanism allows for two main advantages: First, the packaging box 1 can be placed directly onto the carrying mechanism after the items are placed inside, thus making placement more convenient. Second, the packaging box 1 can be placed on the carrying mechanism first, and then items can be added inside.

[0032] Reference Figure 7 and Figure 8 The guide rod 4 is connected to the frame 2. The guide rod 4 includes a first section 43 and a second section 44 connected to each other. The first section 43 and the second section 44 are arranged sequentially along a first direction. The first section 43 is inclined upward along the first direction, and the second section 44 is inclined towards the support mechanism along the first direction to drive the cover 12 to flip. When the cover 12 is in the second position, the angle between the plane where the opening of the box 11 is located and the plane where the cover 12 itself is located is less than 90°. The cover 12 switches from the first position to the second position by rotating around the rotation axis. After the packaging box 1 is placed on the support mechanism, the conveying device 3 drives the packaging box 1 to move. When the packaging box 1 moves relative to the guide rod 4, the guide rod 4 abuts against the cover 12 and slides relative to the cover 12, thereby guiding the cover 12 to flip to the second position. At this time, the cover 12 is above the opening and covers the opening of the box 11 to a certain extent. When the cover 12 slides along the first segment 43, the first segment 43 tilts upward, thereby driving the cover 12 to flip upward. When the cover 12 passes through the first segment 43 and slides along the second segment 44, the second segment 44 tilts in the first direction toward the direction of the bearing mechanism, thereby causing the cover 12 to flip toward the position of the opening, thereby reaching the second position.

[0033] The capping device 5 is positioned downstream of the guide rod 4 along a first direction. The capping device 5 includes a pressing head positioned above the packaging box 1 along a second direction. The pressing head can move along the second direction to press the cover 12, which is the orientation of the opening of the box 11. After the cover 12 is guided to the second position by the guide rod 4, the capping device 5 presses the cover 12 to the third position. When the cover 12 is in the third position, it is fixedly covering the opening of the box 11, and a latch secures the cover 12 to the opening. Specifically, when the packaging box 1 in the second state is conveyed by the conveying device 3 to the area below the capping device 5, the pressing head moves closer to the packaging box 1 along the second direction, thereby pressing the cover 12 tightly against the opening of the box 11 and locking the cover 12 onto the box 11. This allows the cover 12 to switch from the second position to the third position. The latch can be implemented in various ways. For example, it can consist of a latch and a buckle. When one cover 12 is provided, one of the latch and the buckle is provided on the cover 12, and the other is provided on the box 11. When the cover pressing device 5 presses down on the cover 12, the latch and the buckle are fixed together, thereby fixing the cover 12 to the box 11. Similarly, when two covers 12 are provided, the latch and the buckle are provided on the two covers respectively.

[0034] In some embodiments, the second segment 44 remains abutting against the cover 12 to prevent the cover 12 from tipping out before the package 1 continues to be conveyed past the guide rod 4. The capping device 5 may be disposed adjacent to the second segment 44, for example, the distance between the capping device and the second segment 44 may be no less than the length of the package 1 along the first direction, thereby allowing the cover 12 to be pressed down by the pressure head before it disengages from the second segment 44.

[0035] In some embodiments, the capping device 5 may further include a moving mechanism connected to the frame 2, and a pressing head connected to the moving mechanism. The moving mechanism is used to adjust the position of the pressing head along a first direction, so that the position of the pressing head can be adjusted according to the packaging box 1 to be sealed, so that the pressing head can press the cap 12 before the cap 12 disengages from the second segment 44. The moving mechanism may be a linear motion mechanism commonly used in industrial equipment, such as a synchronous belt linear motion mechanism, a gear and rack linear motion mechanism, a lead screw module linear motion mechanism, a cylinder linear motion mechanism, etc.

[0036] According to some embodiments of this utility model, the sealing device includes two guide rods 4, namely a left rod 41 and a right rod 42, which are respectively arranged on both sides of the conveying path of the packaging box 1. The packaging box 1 includes a single-lid packaging box 1 and a double-lid packaging box 1. The single-lid packaging box 1 has only one lid 12, in which case only one guide rod 4 is needed to switch the lid 12 from the first position to the second position. The double-lid packaging box 1 has two oppositely arranged lids 12, namely a left lid 13 and a right lid 14. In this case, two guide rods 4 are needed to guide the two lids 12, namely the left rod 41 and the right rod 42. The left rod 41 and the right rod 42 are respectively arranged on both sides of the conveying path of the packaging box 1. The left rod 41 guides the left lid 13 to rotate from the first position to the second position around the rotating axis, and the right rod 42 guides the right lid 14 to rotate from the first position to the second position around the rotating axis.

[0037] According to some embodiments of this utility model, the end of the first segment 43 furthest from the second segment 44 is lower than the supporting mechanism along the first direction. When the cover 12 is in the first position, the cover 12 may fold outwards at an excessive angle under gravity, potentially preventing the upper part of the first segment 43 from directly contacting the lower side of the cover 12 in the first position, which could lead to jamming. Therefore, by lowering the end of the first segment 43 furthest from the second segment 44 along the first direction below the supporting mechanism, the cover 12 can be smoothly guided by the first segment 43. Furthermore, the angle at which the first segment 43 tilts upwards along the first direction does not exceed 45 degrees, and the angle at which the second segment 44 tilts towards the supporting mechanism along the first direction does not exceed 45 degrees, further preventing the packaging box 1 from jamming when passing through the guide rod 4.

[0038] In some embodiments, the second segment 44 is inclined downward in a first direction, so that the cover 12, which is guided upward by the first segment 43, can be further inward and downward against the opening of the box 11 as it passes through the second segment 44, so that the cover 12 at least partially covers the opening of the box 11.

[0039] According to some embodiments of this utility model, the left rod 41 and the right rod 42 are symmetrically arranged on both sides of the conveying path of the packaging box 1 so that the cover 12 flips synchronously. In some embodiments, when the packaging box 1 has a left cover 13 and a right cover 14, synchronous flipping of the left cover 13 and the right cover 14 allows for more accurate alignment, thus necessitating the symmetrical arrangement of the left rod 41 and the right rod 42. In other embodiments, the left cover 13 needs to be flipped first, followed by the right cover 14. In this case, the left rod 41 and the right rod 42 can be adjusted to accommodate different requirements of the cover 12.

[0040] According to some embodiments of this utility model, the distance between the first segment 43 of the left rod 41 and the first segment 43 of the right rod 42 is greater than the width of the box 11, so that the packaging box 1 can pass between the left rod 41 and the right rod 42. When the packaging box 1 passes through the first segment 43, since the first segment 43 and the box 11 are at the same height, in order to avoid interference between the box 11 and the first segment 43, the distance between the first segment 43 of the left rod 41 and the first segment 43 of the right rod 42 is greater than the width of the box 11. The distance between at least a portion of the second segment 44 of the left rod 41 and the second segment 44 of the right rod 42 is less than the width of the box 11. After the lid 12 is flipped, if the angle between the plane where the opening of the box 11 is located and the plane where the lid 12 itself is located is less than 90°, the lid 12 will switch to the second position under the action of gravity; if the angle between the plane where the opening of the box 11 is located and the plane where the lid 12 itself is located is greater than 90°, the lid 12 will return to the first position under the action of gravity. Therefore, the distance between at least a portion of the second segment 44 of the left rod 41 and the second segment 44 of the right rod 42 is less than the width of the box 11, thereby ensuring the flipping angle of the cover 12 so that it can be switched to the second position after passing through the guide rod 4.

[0041] According to some embodiments of this utility model, the sealing device further includes a first scanning device 6 and a second scanning device 7. The first scanning device 6 is disposed upstream of the guide rod 4 along a first direction and is used to scan the information of the packaging box 1. The second scanning device 7 is disposed upstream of the guide rod 4 along the first direction and is used to scan the information of the items inside the packaging box 1. To ensure that the items are placed in the correct packaging box 1, before sealing the packaging box 1, the first scanning device 6 scans the information of the packaging box 1, and the second scanning device 7 scans the information of the items inside the packaging box 1, thereby making a correspondence to ensure that the information of the items corresponds to the information of the packaging box 1.

[0042] According to some embodiments of this utility model, the sealing equipment further includes a labeling device 8, which is disposed downstream of the capping device 5 along a first direction. The labeling device 8 is used to apply labels to the packaging box 1. After sealing, labels need to be applied to the packaging box 1 to record information about the packaging box 1. Furthermore, labels are applied to the locking positions to prevent the locking from being opened again.

[0043] According to some embodiments of this utility model, the sealing equipment further includes an information processing device. The first scanning device 6, the second scanning device 7, and the labeling device 8 are all signal-connected to the information processing device. The information processing device is used to generate printing information based on the information of the packaging box 1 and / or the information of the items inside the packaging box 1. The labeling device 8 is also used to print labels based on the printing information. By directly generating printing information from the information scanned by the first scanning device 6 and the second scanning device 7 and printing the labels, which are then directly affixed to the packaging box 1, it is not only more convenient but also greatly improves efficiency.

[0044] According to some embodiments of this utility model, the sealing equipment also includes a visual inspection device 9, which is located downstream of the capping device 5 and used to inspect the appearance of the packaging box 1. To ensure the packaging box 1 is properly sealed and to avoid defective products, a visual inspection device 9 is installed for inspection. The visual inspection device 9 captures and analyzes images in real time using a camera or similar device, accurately identifying the shape, size, color, and other features of objects, thereby achieving high-precision inspection results. The visual inspection device 9 mainly consists of two parts: hardware and software. The hardware part includes a camera (such as an industrial camera), lens, light source, and sensors. The light source optimizes the contrast of the target object; the camera captures images; and the lens determines the resolution and field of view. The software part covers image processing algorithms and a decision-making system. Through edge detection, feature matching, deep learning, and other algorithms, the system can extract key information from images. In some advanced applications, such as the 3D visual inspection device 9, it also includes an image acquisition card and AI software algorithms, where the AI ​​algorithms are relatively more valuable. The visual inspection device 9 utilizes computer control and artificial intelligence technology to collect and process product image information through a camera, automatically identifying product defects, damage, or other problems. Its workflow is as follows: The device detects image information of the product being inspected through a camera, and performs image acquisition, sampling, and digital signal conversion processing on the raw image information. The processed digital signal is then input into a computer for image processing, feature extraction, defect identification, and other algorithmic analysis. The system determines whether the product has defects, damage, or other problems, and outputs the detection results to the production control system via a data interface, enabling automatic control and optimization of the production process.

[0045] According to some embodiments of this utility model, a roller is rotatably provided on the pressing head. The roller is located at the end of the pressing head facing the bearing mechanism and is used to abut against the cover 12. When the pressing head presses against the cover 12, the pressing head will slide to a certain extent relative to the cover 12. Therefore, the roller is provided to abut against the cover, thereby avoiding damage to the packaging box 1.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
