Description

Technical Field

[0001] This invention relates to the field of packaging technology, and in particular to a packaging device. Background Technology

[0002] With societal development, the demand for online shopping is increasing, and more products are being delivered to shoppers via long-distance transportation. This places higher demands on product packaging. For boxed products, six-sided packaging is increasingly preferred to achieve full enclosure and better waterproofing and dustproofing.

[0003] Chinese patent application number 202010992205.8, entitled "A Wrapping Method and Wrapping Machine," discloses a method for packaging a box on all six sides. This method allows for packaging on all six sides of the box. However, this method requires the box to be rotated 90 degrees, which is unsuitable for many products, potentially damaging the contents, and can also damage the box itself, affecting the final packaging quality and effect. Summary of the Invention

[0004] Therefore, it is necessary to provide a new type of packaging equipment to address the aforementioned problems that exist when packaging products on all six sides using existing methods.

[0005] The packaging equipment includes a conveyor table, a film steering frame, a sealing unit, and a film conveying unit. The film steering frame and the sealing unit are located above the conveyor table and along the conveying direction of the conveyor table. The film steering frame is located upstream of the sealing unit. The film conveying unit outputs film to the film steering frame, where the film steering frame folds and turns the film. The film steering frame includes a front steering frame, a left steering frame, a right steering frame, a lower left steering frame, and a lower right steering frame. The front steering frame spans above the conveyor table. The left and right steering frames are located on opposite sides of the conveyor table, with the front steering frame positioned upstream of the left and right steering frames. The lower left steering frame is located at the bottom of the left steering frame and forms an acute angle with the conveying direction of the conveyor table. A space for the film to pass through is provided below the lower left steering frame. The lower right steering frame is located at the bottom of the right steering frame and forms an acute angle with the conveying direction of the conveyor table. A space for the film to pass through is provided below the lower right steering frame.

[0006] In one embodiment, the angle between the conveying directions of the lower left turntable and the conveyor platform is equal to the angle between the conveying directions of the lower right turntable and the conveyor platform.

[0007] In one embodiment, the angle between the conveying directions of the lower right turntable and the conveyor table is 45°.

[0008] In one embodiment, both the lower left rotating frame and the lower right rotating frame adopt a right-angled tripod structure.

[0009] In one embodiment, the front turntable is inclined in an upstream direction toward the conveyor table.

[0010] In one embodiment, the sealing unit includes a film insertion mechanism and a film melting mechanism; the film insertion mechanism is located downstream of the film melting mechanism along the conveying direction of the conveyor table.

[0011] In one embodiment, the film insertion mechanism is located on both sides of the conveyor table, and the insertion direction of the film insertion mechanism is perpendicular to the sealing direction of the film melting mechanism.

[0012] In one embodiment, the conveyor platform adopts a split structure design, including a front conveyor platform and a rear conveyor platform; the front conveyor platform is located upstream of the film bogie to convey the product to be packaged to the film bogie; the rear conveyor platform is located downstream of the sealing unit to convey the sealed product.

[0013] In one embodiment, the lower left rotating frame and the lower right rotating frame are located between the front conveyor and the rear conveyor, and the upper surfaces of the lower left rotating frame and the lower right rotating frame are not higher than the upper surface of the front conveyor.

[0014] In one embodiment, the packaging equipment also includes a push rod located near the front conveyor to assist in moving the product to be packaged from the front conveyor to the rear conveyor.

[0015] In one embodiment, the film output by the film conveying unit is a folded film, and the folds are along the length of the film.

[0016] In one embodiment, the front rotating frame is a symmetrical bent rod structure; wherein the bending point of the bent rod is aligned with the crease of the film in the vertical direction, and the two ends of the bent rod are respectively connected to the left rotating frame and the right rotating frame in a downward inclined direction.

[0017] In one embodiment, the packaging equipment further includes a heat shrink packaging unit located downstream of the sealing unit.

[0018] In the aforementioned packaging equipment, a film turning frame and a sealing unit are sequentially arranged along the conveyor table in the direction of product transport. The film is transported to the film turning frame by the film conveyor unit, and then the film turning frame turns and spreads the film. After the sealing unit performs a pre-sealing treatment on the front end of the spread film, the product can directly enter the film inside the film at the film turning frame during the subsequent transport process with the conveyor table. The product is then moved to the sealing unit for post-sealing treatment in the form of a covered film. This achieves the goal of completing the full packaging operation of the product without any product flipping or adjustment, thus avoiding the bumping and damage to the product caused by flipping it during the full packaging process, and greatly improving the packaging quality and effect of the product.

Figure 9 The diagram shows the external structure of a six-sided box as a product to be packaged and after being sealed by a packaging device according to an embodiment of the present invention.

[0036] In one embodiment of the packaging equipment of the present invention, there are a conveyor table 1, a film turning frame 2, a sealing unit 3, and a film conveying unit 4. The conveyor table 1 is horizontally mounted on the ground and continuously conveys the six-sided box 5 to be packaged in a straight line. The film turning frame 2 and the sealing unit 3 are both located above the conveyor table 1, and along the conveying direction of the conveyor table 1, the film turning frame 2 is located upstream of the sealing unit 3. That is, the six-sided box 5 to be packaged first passes through the film turning frame 2 under the conveying action of the conveyor table 1, and then passes through the sealing unit 3. The film conveying unit 4 is provided with a film 6 for packaging the six-sided box 5, and conveys the film 6 to the film turning frame 2, where the film turning frame 2 turns and bends the film 6 to fit over the outer surface of the six-sided box 5 that has passed through the film turning frame 2.

[0037] In this embodiment, the membrane bogie 2 adopts a frame structure, including a front bogie 21, a left bogie 22, a right bogie 23, a lower left bogie 24, and a lower right bogie 25 fixedly connected by welding. The front bogie 21 spans across the top of the conveyor platform 1, while the left bogie 22 and right bogie 23 are located on opposite sides of the conveyor platform 1 in the vertical direction. The front bogie 21 is located upstream of the conveyor platform 1 compared to the left bogie 22 and right bogie 23.

[0038] The lower left rotating frame 24 is directly fixed to the bottom of the left rotating frame 22 by horizontal welding, and a space for the film to pass through is provided below the lower left rotating frame 24 for the film 6 to pass through in the horizontal direction. At the same time, when fixing the lower left rotating frame 24 to the left rotating frame 22, the turning edge of the lower left rotating frame 24 is kept at an acute angle to the conveying direction of the conveyor table 1.

[0039] The lower right rotating frame 25 is directly fixed to the bottom of the right rotating frame 23 by horizontal welding, and a space for the film to pass through is provided below the lower right rotating frame 25 for the film 6 to pass through in the horizontal direction. At the same time, when fixing the lower right rotating frame 25 and the right rotating frame 23, the turning edge of the lower right rotating frame 25 is kept at an acute angle to the conveying direction of the conveyor table 1.

[0040] See Figures 5 to 9As shown in the figure, the film turntable 2 can perform zonal turning and folding operations on the film 6 conveyed by the film conveying unit 4, enabling the film 6 to enter the film turntable 2 in a specific form and cover the six-sided box body 5 to be packaged. Among them, along the width direction of the film 6, the film 6 can be divided into a left region 62, a middle region 61, and a right region 63.

[0041] First, along the transmission direction of the conveying table 1, the film 6 vertically drops at the upstream position of the front turntable 21. During this process, the left region 62 of the film 6 makes a first turn downward in the downstream direction around the connection position between the front turntable 21 and the left turntable 22, and the right region 63 of the film 6 makes a first turn downward in the downstream direction around the connection position between the front turntable 21 and the right turntable 22. At this time, standing at the downstream position of the film turntable 2 and observing along the direction of the film 6 dropping, the film 6 is folded into a "冂" shape.

[0042] Next, when the film 6 drops close to the conveying table 1, the film conveying unit 4 continues to convey the film 6. The end of the left region 62 in the film 6 bypasses the bottom of the left turntable 22 for a second turn and extends to the lower position below the left lower turntable 24, and then makes a third turn around the left lower turntable 24 to the upper position above the left lower turntable 24. At this time, part of the left region 62 turns to be parallel to the left lower turntable 24 and points to the downstream direction of the conveying table 1, and another part of the left region 62 turns to be parallel to the left turntable 22 and points to the downstream direction of the conveying table 1; at the same time, the end of the right region 63 in the film 6 bypasses the bottom of the right turntable 23 for a second turn and extends to the lower position below the right lower turntable 25, and then makes a third turn around the right lower turntable 25 to the upper position above the right lower turntable 25. Part of the right region 63 turns to be parallel to the right lower turntable 25 and points to the downstream direction of the conveying table 1, and another part of the right region 63 turns to be parallel to the right turntable 23 and points to the downstream direction of the conveying table 1; at the same time, the end of the middle region 61 of the film 6 makes a 90° turn around the bottom of the front turntable 21 to a state parallel to the conveying table 1 and pointing to the downstream direction. At this time, by adjusting the translation distance of the left region 62 in the film 6 towards the right turntable 23 and the translation distance of the right region 63 towards the left turntable 22, the left region 62 of the film above the left lower turntable 24 and the right region 63 of the film above the right lower turntable 25 can form partial overlap, forming a "口" shape with partial overlap at the bottom.

[0043] Among them, the overlap amount between the left region and the right region in the film can be freely adjusted according to the packaging requirements, such as adjusting the positional relationship between the left lower turntable and the right lower turntable along the conveying direction of the conveying table, or adjusting the positional relationship between the left region and the right region in the film along the conveying direction of the conveying table when they respectively make the second turn.

[0044] Then, when all three areas of the film 6 have turned into an "U" shape, the film conveying unit 4 continues to convey the film 6, so that the three areas of the film 6 extend to the sealing unit 3, and the sealing unit 3 completes the front sealing operation of the free end of the film 6, thus completing the laying operation of the film 6.

[0045] Finally, the six-sided box 5 located on the conveyor table 1 enters the area formed by the left rotating frame 22, the right rotating frame 23, the lower left rotating frame 24, and the lower right rotating frame 25, thus entering the internal space formed by the turning and folding of the film 6. The front end of the six-sided box 5 contacts the front seal of the film 6. As the film conveying unit 4 continuously conveys the film 6 and the conveyor table 1 conveys the six-sided box 5, the film 6 passes through the sealing unit 3 along with the six-sided box 5. The sealing unit 3 then performs a rear-seal operation on the film at the rear end of the six-sided box, thus completing the full packaging of all six sides of the six-sided box 5. Simultaneously with the rear-seal operation of the film passing through the rear end of the six-sided box, the sealing unit 3 also completes the front-seal operation of the subsequent film, allowing the subsequent six-sided boxes to be directly conveyed to the film turning frame for continuous packaging.

[0046] In this embodiment, both the lower left rotating frame 24 and the lower right rotating frame 25 adopt an isosceles right-angled tripod structure. Specifically, one right-angled side of the lower left rotating frame 24 is fixedly connected to the bottom of the left rotating frame 22 along the conveying direction of the conveyor table 1, with its hypotenuse positioned upstream of the other right-angled side. Similarly, one right-angled side of the lower right rotating frame 25 is fixedly connected to the bottom of the right rotating frame 23 along the conveying direction of the conveyor table 1, with its hypotenuse positioned upstream of the other right-angled side.

[0047] At this point, the inclined side of the lower left rotating frame acts as a turning edge, allowing the film located below the lower left rotating frame to turn around the inclined side and then directly face the downstream direction of the conveyor table; similarly, the inclined side of the lower right rotating frame acts as a turning edge, allowing the film located below the lower right rotating frame to turn around the inclined side and then directly face the downstream direction of the conveyor table. Thus, by utilizing the 45° inclined sides of the lower left and right rotating frames as turning edges, the left and right sides of the film can be turned in a parallel manner towards the downstream direction of the conveyor table, resulting in a neat, elongated overlapping area between the left and right sides of the film (e.g., ...). Figures 7 to 9 As shown), this improves the aesthetics and security of the packaging; on the other hand, the tripod-shaped lower left and lower right rotating frames can guide the film located below them to spread out, allowing the film to smoothly complete the second and third turns, avoiding tangling during the film turning process, and improving the smoothness and stability of the film turning and conveying.

[0048] In other embodiments, depending on the packaging effect requirements, the included angle between the turning edges of the lower left and lower right rotating frames can be adjusted, i.e., the structural shape of the lower left and lower right rotating frames can be adjusted, thereby changing the film orientation after the third turn. For example, by appropriately increasing the included angle between the turning edges of the lower left and lower right rotating frames, the left side of the film can be biased towards the right rotating frame, and the right side of the film can be biased towards the left rotating frame, thus creating an overlapping effect. Similarly, in other embodiments, the included angles of the turning edges of the lower left and lower right rotating frames can be set differently to obtain an asymmetrical overlapping effect to meet different packaging requirements.

[0049] In a sealing unit 3 of a packaging device according to an embodiment of the present invention, a film insertion mechanism 31 and a film welding mechanism 32 are included. The film insertion mechanism 31 is located downstream of the film welding mechanism 32 along the conveying direction of the conveyor table 1. That is, after the six-sided box 5 of the conveyor table 1 passes through the film guide frame 2, it passes through the film welding mechanism 32 and the film insertion mechanism 31 in sequence.

[0050] At this point, before using the film melting mechanism to melt and seal the film covering the outer surface of the six-sided box, the film at the rear end of the six-sided box can be pre-inserted using the film edge insertion mechanism located between the film melting mechanism and the six-sided box, so that an M-shaped seal is formed after sealing, thereby improving the aesthetics and neatness of the six-sided box packaging.

[0051] In this embodiment, the film insertion mechanism 31 consists of two horizontally positioned cylinders, while the film welding mechanism 32 is positioned vertically. Thus, after the six-sided box passes through the film insertion mechanism, the conveyor's movement is paused, and the cylinder-structured film insertion mechanism extends to fold the film on both sides of the rear end of the six-sided box into an M-shape. Then, the film welding mechanism is controlled to weld and seal the folded film, thereby achieving full packaging of all six sides of the six-sided box.

[0052] Furthermore, the conveyor 1 adopts a split structure design, including a conveyor 1a located upstream of the film bogie and a rear conveyor 1b located downstream of the sealing unit, and the front conveyor 1a and the rear conveyor 1b are driven and controlled independently.

[0053] At this point, as the six-sided box moves through the film guide frame to the sealing unit, the rear conveyor can be independently driven and controlled to keep the six-sided box requiring sealing at the correct position for edge insertion and sealing. During this process, the front conveyor can continue to operate, transporting the next six-sided box to be packaged to the film guide frame. This allows for the continuous transfer of six-sided boxes to the film guide frame, improving the efficiency of packaging the six-sided boxes.

[0054] Furthermore, the lower left rotating frame 24 and the lower right rotating frame 25 in the film rotating frame 2 are placed between the front conveyor table 1a and the rear conveyor table 1b, and the upper surface of the lower left rotating frame 24 and the upper surface of the lower right rotating frame 25 are not higher than the upper surface of the front conveyor table 1a.

[0055] In this way, when the front conveyor transports the six-sided box to be packaged to the film turning frame, the six-sided box can slide smoothly onto the lower left and lower right turning frames. This not only avoids jamming of the six-sided box and ensures its smooth transfer, but also prevents the film wrapped around the lower left and lower right turning frames from being squeezed and damaged, thus protecting the film and ensuring the final packaging quality and effect.

[0056] Further reading Figure 3 and Figure 4 As shown, in a packaging device according to an embodiment of the present invention, a push rod 7 is also provided. At the same time, two front conveyor platforms 1a are provided upstream of the film steering frame 2. The two front conveyor platforms 1a are arranged in a parallel and spaced manner and move synchronously via a conveyor belt. The push rod 7 is located between the two front conveyor platforms 1a and is driven by an independent motor to extend out of the front conveyor platform 1a to assist in pushing the six-sided box 5 from the front conveyor platform 1a to the rear conveyor platform 1b.

[0057] At this point, when the six-sided box is moved to the lower left and lower right rotating frames but lacks the drive of the front and rear conveyor platforms, a push rod can be used to assist in pushing the six-sided box, allowing it to smoothly slide past the lower left and lower right rotating frames and move to the rear conveyor platform, ensuring the smooth progress of the packaging operation for the six-sided box.

[0058] In this embodiment, for the film that falls from top to bottom onto the film bogie upstream and then turns and spreads downstream onto the film bogie, by designing the front conveyor platforms as two parallel and spaced-apart units and placing the push rod between the two front conveyor platforms, the six-sided box can be assisted in being pushed by controlling the reciprocating extension and retraction of the push rod without affecting the continuous film spreading operation on the film bogie. Similarly, in other embodiments, depending on the installation environment of the packaging equipment and the way the film spreads on the film bogie, the push rod can also be independently fixed to the side of the front conveyor platform, and the six-sided box can be assisted in being pushed by controlling the reciprocating swing of the push rod in the horizontal direction.

[0059] Furthermore, in this embodiment, the film insertion mechanism uses a cylinder mechanism driven by pollution-free compressed air, which can minimize the pollution that may be caused to the surrounding environment during its operation, especially the pollution that may be caused to the packaged product, thereby ensuring the quality and effect of the final packaging.

[0060] In addition, depending on the shape of the six-sided box and its placement on the front conveyor, the positions of the film insertion mechanism and the film sealing mechanism can be adjusted. For example, the film insertion mechanism can be adjusted to be set in the vertical direction, while the film sealing mechanism can be adjusted to be set in the horizontal direction, so as to ensure the M-shaped folding effect of the film at the rear end of the six-sided box, thereby ensuring the packaging effect of the sealing.

[0061] In a packaging apparatus according to one embodiment of the present invention, the film 6 wound on the film roller 41 in the film conveying unit 4 is in the form of a folded film, and the folds of the film 6 are along the length direction of the film. In this way, when packaging films of the same width, the length of the roller used is only half the required width of the film, thereby reducing the external size of the film conveying unit and reducing the manufacturing cost and installation space occupied by the entire packaging apparatus.

[0062] Furthermore, for the selected folded film, the front rotating frame 21 in this embodiment adopts a symmetrical bending rod structure. The bending point of the bending rod is aligned with the crease of the film in the vertical direction, and the two ends of the bending rod are connected to the left and right rotating frames respectively in a backward tilting direction. That is, the front rotating frame is fixed across the left and right rotating frames with the middle bending point tilted forward, and the bending point of the front rotating frame is located in the middle of the left and right rotating frames.

[0063] At this point, when the folded film is transported to the film bogie, by placing the film on the front bogie and aligning the creases of the film vertically with the bending points of the front bogie, the film can be symmetrically unfolded by the bending rod-like front bogie as it falls vertically. This allows the left and right sides of the unfolded film to slide towards the left and right bogies respectively, thus enabling the film to be accurately unfolded and quickly slid into the film bogie, improving the film spreading efficiency.

[0064] See Figure 1 and Figure 2 As shown, the film conveying unit 4 is also equipped with multiple conveying rollers 42 and a power roller 44 driven by a drive motor 43. The power roller 44 is located on the conveying path of the film 6 and works in conjunction with one of the conveying rollers 42 to provide conveying power to the film 6, actively conveying the film 6 to the film bogie 2, thereby coordinating with the movement of the six-sided box to actively convey the film.

[0065] At this point, the active conveying of the film by the power rollers can reduce the moving resistance encountered when the six-sided box comes into contact with the film, allowing the six-sided box to move smoothly with the conveyor table. On the other hand, it can also reduce the force exerted by the six-sided box on the film at the front end in the direction of movement, so as to avoid damage to the front seal already formed at the front end of the six-sided box, and ensure the smooth progress of the packaging operation of the six-sided box.

[0066] Additionally, see Figure 1 As shown, in one embodiment of the packaging equipment of the present invention, a heat shrink packaging unit 8 is further provided. The heat shrink packaging unit 8 is located downstream of the sealing unit 3 and is used to perform heat shrink packaging on the six-sided box 5 after the fusion seal is completed. In this way, the coverage of the film on the surface of the six-sided box can be increased, further improving the packaging effect and quality of the six-sided box.

[0067] Based on the above description of the packaging process for a six-sided box, it can be seen that this packaging equipment can achieve full packaging of all six sides of the box without any flipping action, ensuring product protection during the entire packaging process. Similarly, the packaging equipment in the above embodiments can also achieve the same full packaging effect for products of other shapes, not limited to six-sided boxes. For example, for cylindrical products, multi-faceted products, or spherical products, full packaging can also be completed without any flipping action, achieving full protection of the product during the packaging process and improving the quality and effect of the full packaging.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
