Description

Technical Field

[0001] The present disclosure relates to the technical field of papermaking and packaging, and in particular to a roll packaging machine and a packaging method. Background Art

[0002] During the roll production process, since the rolls are easily affected by external forces such as collision and friction during handling, storage and transportation, roll packaging machines are generally used to tightly wrap the packaging materials around the outside of the roll to form a protective layer, which can effectively prevent the roll surface from being scratched and worn, and at the same time prevent the paper edges from being damaged or falling off, thereby ensuring the integrity and quality of the paper.

[0003] However, when using roll-to-roll packaging machines to wrap rolls, excess, irregular packaging material can easily form at the edges or ends of the rolls. This excess material can appear warped or uneven, requiring manual cleaning and trimming. This increases labor costs, prolongs the packaging time for individual products, hinders smooth production line operation, and reduces overall packaging efficiency. Summary of the Invention

[0004] The present disclosure is made in view of the above problems and provides a roll packaging machine and a packaging method, which reduce the possibility of excess and irregular packaging material portions appearing at the edge or end of the roll, thereby saving labor and maintenance costs.

[0005] According to one aspect of the present disclosure, a roll packaging method is provided, which is applied to a roll packaging machine. The roll packaging machine includes a wrapping paper feeding device, a waiting area for packaging, two folding devices, a cutting device, and a controller respectively connected to the wrapping paper feeding device, the waiting area for packaging, the two folding devices, and the cutting device. The waiting area for packaging has a drive roller assembly. The roll packaging method includes:

[0006] Installing the roll onto the driving roller assembly provided in the area to be packaged;

[0007] A controller is used to control the wrapping paper feeding device to feed wrapping paper to the reel, and to control the driving roller assembly to drive the reel to rotate, so that the wrapping paper is wound around the circumference of the reel. When the wrapping paper is wound to a preset number of layers, the cutting device is controlled to cut the wrapping paper, wherein the width of the wrapping paper is greater than the width of the reel.

[0008] After the tail of the wrapping paper is bonded to the wound wrapping paper, the controller drives the two folding devices to fold the parts of the wrapping paper located at both ends of the roll to obtain a packaged roll.

[0009] According to another aspect of the present disclosure, a roll packaging machine is provided, comprising a packaging paper feeding device, a waiting area for packaging, two folding devices, a cutting device, and a controller signal-connected to the packaging paper feeding device, the waiting area for packaging, the two folding devices, and the cutting device, wherein the waiting area for packaging has a drive roller;

[0010] The controller is used to install the roll onto the driving roller assembly provided in the area to be packaged;

[0011] The controller is further configured to control the wrapping paper feeding device to feed wrapping paper to the reel, and to control the driving roller assembly to drive the reel to rotate, so that the wrapping paper is wound around the circumference of the reel until the wrapping paper is wound to a preset number of layers, and then control the cutting device to cut the wrapping paper, wherein the width of the wrapping paper is greater than the width of the reel;

[0012] After the tail of the wrapping paper is bonded to the wound wrapping paper, the controller is further used to drive the two folding devices to fold the parts of the wrapping paper located at both ends of the roll to obtain a packaged roll.

[0013] In one or more technical solutions provided in the embodiments of the present disclosure, first, a controller controls a wrapping paper feeding device to feed paper to a reel, while a drive roller assembly drives the reel to rotate, causing the wrapping paper to be wound circumferentially around the reel. When the wrapping reaches a preset number of layers, the controller controls a cutting device to cut the wrapping paper. The predetermined number of layers of cutting ensures that the wrapping paper stops winding at an appropriate length, avoiding the generation of excess paper due to excessive winding and reducing the possibility of excess material, i.e., small tails, at the edges or ends of the reel. Second, after the wrapping paper is cut, the tail of the wrapping paper is bonded to the already wound wrapping paper, so that the tail is fixed to the wrapping layer of the reel and forms a single unit with the already wound wrapping paper. This prevents the tail of the wrapping paper from warping or spreading out in the axial direction of the reel due to unfixed wrapping. On the other hand, on the basis of the paper tail being fixed on the packaging layer of the roll, two folding devices are used to gradually bend the parts of the packaging paper located at both ends of the roll toward the side of the roll. In this process, the paper tail part of the packaging paper is also included in the folding range, thereby avoiding the small tail phenomenon caused by the unbonded paper tail of the packaging paper, reducing the possibility of the paper tail of the packaging paper being curled up and uneven, and no subsequent manual trimming is required. Therefore, labor costs are saved, the packaging time of a single product is reduced, the production time is shortened, the overall packaging efficiency is improved, and the appearance of the packaged roll is regular.

[0014] On this basis, the entire process of the roll packaging method of the embodiment of the present invention relies on the cooperation between the various devices of the roll packaging machine and the controller to realize automated packaging. After the roll is installed on the drive roller assembly, the controller coordinates the paper feeding, roll rotation and cutting actions without the need for a large amount of manual intervention, greatly improving packaging efficiency and reducing labor costs.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present disclosure more clearly understood, the present disclosure is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this disclosure, "multiple" means two or more, unless otherwise clearly and specifically defined. "Several" means one or more, unless otherwise clearly and specifically defined.

[0025] In the description of the present disclosure, it should be understood that the terms "up", "down", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present disclosure.

[0026] In the description of this disclosure, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0027] The roll production process is fraught with challenges in handling, storing, and transporting the rolls. During handling, the slightest carelessness can cause the rolls to collide with handling tools or other objects. During storage, poor warehouse conditions, such as uneven floors, can easily cause the rolls to squeeze and rub against each other when stacked. During transportation, the jolting of vehicles and the relative displacement of cargo can also subject the rolls to various external forces. For this reason, roll wrapping machines are typically used to tightly wrap the packaging material around the rolls. This protective layer acts like a sturdy armor around the rolls, effectively protecting the roll surface from scratches and wear, while also preventing damage to the edges and corners of the paper, thereby fully ensuring the integrity and quality of the paper.

[0028] However, when using roll-to-roll packaging machines to wrap rolls, excess, irregular packaging material can easily form at the edges or ends of the rolls. This excess material can appear warped or uneven, requiring manual cleaning and trimming. This increases labor costs, prolongs the packaging time for individual products, hinders smooth production line operation, and reduces overall packaging efficiency.

[0029] In response to the above problems, the embodiments of the present disclosure provide a roll packaging machine and a packaging method, which reduce the possibility of excess and irregular packaging material portions appearing at the edges or ends of the roll, thereby saving manpower and maintenance costs.

[0030] In practical applications, the roll packaging method provided by the embodiment of the present disclosure is applied to the roll packaging machine of the embodiment of the present disclosure.

[0031] Figure 1 FIG. 1 shows a schematic structural diagram of a roll packaging machine according to an embodiment of the present disclosure. Figure 1 As shown, the roll packaging machine of the embodiment of the present disclosure includes a wrapping paper feeding device (not shown in the figure), a waiting area 100, two folding devices 200, a cutting device (not shown in the figure), and a controller (not shown in the figure) that is signal-connected to the wrapping paper feeding device, the waiting area 100, the two folding devices 200, and the cutting device. Among them, the waiting area 100 has a drive roller assembly 110, and the roll 300 can be installed on the drive roller assembly 110 in the waiting area 100. It should be understood that the drive roller assembly 110 can include a first drive roller 111 and a second drive roller 112, and the roll 300 can be installed on the first drive roller 111 and the second drive roller 112, so that the controller can be used to control the rotation of the drive roller assembly 110 to drive the roll 300 to rotate.

[0032] It is understandable that the controller may be a chip with signal processing capability, such as a processor in a computer device.

[0033] Each operation in the above method disclosed in the embodiment of the present disclosure can be completed by an integrated logic circuit of the hardware in the processor or an instruction in the form of software. The above processor can be a general-purpose processor, a digital signal processor (DSP), an ASIC, a field-programmable gate array (FPGA) or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component. The general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc. The steps of the method disclosed in the embodiment of the present disclosure can be directly embodied as being executed by a hardware decoding processor, or being executed by a combination of hardware and software modules in the decoding processor. The software module can be located in a memory, such as a random access memory, a flash memory, a read-only memory, a programmable read-only memory or an electrically erasable programmable memory, a register, or other mature storage media in the art. The processor reads the information in the memory and completes the above operations in combination with its hardware.

[0034] In one achievable embodiment, the roll packaging machine of the present disclosure further includes a gluing device connected to the controller signal. It should be understood that the gluing device is used to apply glue to the wrapping paper before packaging so that the wrapping paper can be bonded to the roll during the packaging process.

[0035] In one example, Figure 1 As shown, each hemming device 200 of the disclosed embodiment includes a drive arm 210 and a hemming portion 220, each of which is signal-connected to a controller. It should be understood that the hemming portion 220 is located at one end of the drive arm 210 and is rotationally connected to the drive arm 210. When the hemming portion 220 is in operation, it is located between the drive arm 210 and the end of the reel 300.

[0036] Illustratively, the hem portion 220 of the disclosed embodiment includes a plurality of hem wings 221 fixed to one end of the drive arm 210, wherein the plurality of hem wings 221 are connected to the controller signal. The plurality of hem wings 221 have a common fixing point, so that the plurality of hem wings 211 are combined into a circle.

[0037] For example, the hemming portion of the disclosed embodiment further includes an elastic buffer secured to the hemming flaps 211. The elastic buffer is located at the end of the hemming portion 220 near the roll. In other words, the elastic buffer is located between the hemming flaps 211 and the end of the roll 300. This elastic buffer prevents damage to the wrapping paper during the hemming process, ensuring its integrity and improving the packaging yield.

[0038] In an optional embodiment, the roll packaging machine of the present disclosure further includes a positioning transfer device, which is connected to the controller by signal. The positioning transfer device can transfer the roll to be packaged to the packaging area 100 of the roll packaging machine before packaging.

[0039] In one implementation, the packaging paper feeding device of the disclosed embodiment includes a paper feed roller and an adjustment device, each of which is signal-connected to a controller. The adjustment device is used to adjust the paper feed speed of the paper feed roller. The adjustment device allows for flexible control of the paper feed speed to meet the requirements of different specifications and packaging speeds, thereby improving the applicability and flexibility of the packaging machine.

[0040] The roll wrapping machine of the disclosed embodiment may further include an auxiliary pressing device, which is signal-connected to the controller. The auxiliary pressing device is configured to press the tail of the wrapping paper after it has adhered to the wound wrapping paper, thereby tightly connecting the tail to the wound wrapping paper.

[0041] Based on the above roll packaging machine, Figure 2FIG. 1 is a flow chart showing a roll packaging method according to an embodiment of the present disclosure. Figure 2 The roll packaging method provided by the embodiment of the present disclosure includes:

[0042] Step 201: Install the roll onto the driving roller assembly provided in the area to be packaged.

[0043] In actual application, before packaging the roll, the roll is first installed on the drive roller assembly in the packaging area. The drive roller assembly can be driven by its power to automatically transport the roll in the packaging area according to the set speed and direction.

[0044] Step 202: Use a controller to control the wrapping paper feeding device to feed the wrapping paper to the roll, and control the drive roller assembly to drive the roll to rotate, so that the wrapping paper is wound around the circumference of the roll until the wrapping paper is wound to a preset number of layers, and then control the cutting device to cut the wrapping paper, wherein the width of the wrapping paper is greater than the width of the roll.

[0045] It is understandable that the above-mentioned preset number of layers can be set according to the performance of the wrapping paper and the performance of the roll. Under the premise of ensuring the packaging quality and function, a suitable preset number of packaging layers can be selected.

[0046] In actual application, the controller controls the wrapping paper feeding device to feed paper to the reel, and at the same time, the drive roller assembly drives the reel to rotate, so that the wrapping paper is wound circumferentially around the reel. When the winding reaches a preset number of layers, the controller controls the cutting device to cut the wrapping paper. The cutting method of the preset number of layers can ensure that the wrapping paper stops winding at an appropriate length, avoiding the generation of excess paper due to excessive winding, and reducing the possibility of excess material, i.e., small tails, appearing at the edge or end of the reel from the source.

[0047] Step 203: The tail of the wrapping paper to be wrapped is bonded to the wound wrapping paper, and the controller drives two folding devices to fold the wrapping paper at both ends of the roll to obtain a wrapped roll.

[0048] In actual application, after cutting the wrapping paper, the tail of the wrapping paper is bonded to the already wound wrapping paper, so that the tail is fixed to the packaging layer of the roll. The tail and the already wound wrapping paper form a whole. On the one hand, this prevents the tail of the paper from curling up or spreading out in the axial direction of the roll due to not being fixed. On the other hand, based on the fact that the tail of the paper is fixed to the packaging layer of the roll, two folding devices are used to gradually bend the parts of the wrapping paper at both ends of the roll toward the side of the roll. In this process, the tail of the wrapping paper is also included in the folding range, thereby avoiding the small tail phenomenon caused by the tail of the wrapping paper being not bonded, reducing the possibility of the tail of the wrapping paper curling up and being uneven, and eliminating the need for subsequent manual trimming. Therefore, labor costs are saved, the packaging time of a single product is reduced, production time is shortened, and overall packaging efficiency is improved. The appearance of the wrapped roll is also regular.

[0049] On this basis, the entire process of the roll packaging method of the embodiment of the present invention relies on the cooperation between the various devices of the roll packaging machine and the controller to realize automated packaging. After the roll is installed on the drive roller assembly, the controller coordinates the paper feeding, roll rotation and cutting actions without the need for a large amount of manual intervention, greatly improving packaging efficiency and reducing labor costs.

[0050] In one example, the disclosed embodiment utilizes a controller to control a wrapping paper feeding device to feed paper toward the roll. Before the wrapping paper is wound around the roll, the method further includes: utilizing the controller to control a gluing device to apply glue to the wrapping paper, such that the side of the wrapping paper closest to the roll is coated with glue. This gluing provides a coating of glue on the side of the wrapping paper closest to the roll. As the wrapping paper is wound, the glue fills the tiny gap between the wrapping paper and the roll, increasing friction and adhesion between the two, allowing the wrapping paper to adhere tightly to the roll, preventing relative slippage between the wrapping paper and the roll, and making the surface of the wrapped roll smoother and flatter, thereby improving the product's appearance and visual quality.

[0051] Specifically, the gluing device can be used to apply glue around the edge of the packaging paper, and the gluing device can be avoided from being paused during the gluing process, thereby preventing the sizing agent from gathering together into lumps during the gluing process, and avoiding the phenomenon of small tails appearing during the folding process due to the lumping of the sizing agent.

[0052] In one conceivable implementation, the disclosed embodiment utilizes a controller to drive two folding devices to fold the portions of the wrapping paper at the ends of a roll, thereby producing a packaged roll. Specifically, the process involves: first, attaching the tail of the paper to be wrapped to the wound wrapping paper, and then using the controller to drive the drive arms to move the folding devices to the ends of the roll. Secondly, the folding devices are driven to rotate at a preset speed, folding the portions of the wrapping paper at the ends of the roll during rotation, thereby producing a packaged roll.

[0053] In practice, the folding device precisely folds the wrapping paper at both ends of the roll, resulting in neat, smooth edges without unevenness or warping. This significantly enhances the product's overall aesthetics and visual appeal in the market. Furthermore, the controller-driven folding device automates the folding process, reducing manual operations and labor costs. It also significantly shortens the packaging time for a single roll, improving overall production efficiency.

[0054] It is understandable that the preset speed of the rotation of the above-mentioned folding portion can be determined according to the material and thickness of the packaging paper to ensure that the packaging paper will not be damaged. It is not explained here and can be set according to specific needs.

[0055] For example, since the hemming portion includes a plurality of hemming wings fixed to one end of a driving arm, the method further includes: first, using a controller to drive the driving arm to cause the plurality of hemming wings to abut against the ends of the roll at a predetermined pressure. Then, using the controller to drive the plurality of hemming wings to rotate at a predetermined speed, thereby hemming the portions of the wrapping paper at the ends of the roll during the rotation, thereby obtaining a packaged roll.

[0056] In practice, multiple hemming wings provide comprehensive support for the wrapping paper at the ends of the roll, ensuring a tight fit and more complete, secure wrapping. This tight wrapping enhances package stability, preventing the wrapping paper from loosening at the ends during handling and storage, and providing more reliable protection for the roll.

[0057] For example, the preset pressure and speed of the folding wings can be flexibly adjusted according to factors such as the size of different rolls, the material and thickness of the wrapping paper, so that the folding method can adapt to diverse packaging needs without the need for frequent equipment replacement or complex mechanical modifications, thereby improving the versatility of the equipment and production flexibility.

[0058] In an optional manner, the embodiment of the present disclosure installs the roll onto the drive roller assembly of the area to be packaged, specifically including: using a controller to control the positioning transfer device to transfer the roll to the area to be packaged, so that the roll is located on the drive roller assembly of the area to be packaged.

[0059] In practice, the positioning and transfer device can be automated and coordinated with the entire packaging production line. The controller can control the positioning and transfer device's operation according to the real-time status of the production line, such as the packaging equipment's operating progress and material supply. This ensures that the roll is transferred to the drive roller assembly at the appropriate time, seamlessly integrating the entire production process and avoiding production stoppages or waiting times.

[0060] Illustratively, in the embodiment of the present disclosure, after the tail of the wrapping paper is bonded to the wound wrapping paper, the method further includes: using a controller to control an auxiliary pressing device to press the tail of the paper so that the tail of the paper is tightly connected to the wound wrapping paper. By pressing the tail of the paper with the auxiliary pressing device, it is possible to avoid unevenness such as wrinkles and bulges in the tail of the paper, making the surface of the roll after packaging smoother and flatter, improving the overall appearance quality of the product, gaining a better visual impression for the product in the market, and enhancing the market competitiveness of the product. On the basis of the tail of the paper being tightly connected to the wound wrapping paper by pressing, two folding devices are then used to gradually bend the parts of the wrapping paper located at both ends of the roll toward the sides of the roll. In this process, the tail of the wrapping paper is also included in the folding range, thereby avoiding the small tail phenomenon of the tail of the wrapping paper due to non-bonding, reducing the possibility of the tail of the wrapping paper being warped and uneven, and eliminating the need for subsequent manual trimming, thereby saving labor costs.

[0061] Example 1

[0062] First, the roll is transferred to the packaging area and lowered into place. The wrapping paper is then fed in. During this process, the edge glue sprayer is activated, and the drive roller assembly begins to rotate, driving the roll. Simultaneously, the folding device presses down on the end of the roll to fold the edges. After the desired number of layers are wrapped, the cutter device cuts the wrapping paper, and the drive roller assembly and folding device rotate simultaneously. Finally, the folding completes the packaging process. This process often creates an irregular, untidy portion of packaging material at the edge, known as a "tail." Figure 3 A schematic diagram of a packaged roll according to a first embodiment of the present disclosure is shown.

[0063] Example 2

[0064] First, the reel is transferred to the packaging area and lowered into place. The wrapping paper is then fed in. During this process, the edge glue sprayer is activated, and the drive roller assembly begins to rotate, driving the reel. After the set number of layers has been wrapped, the cutter device cuts the wrapping paper, allowing the tail to adhere to the already wound wrapping paper. An auxiliary pressing device then presses the tail firmly against the wound wrapping paper. The folding device then presses down on the end of the reel to fold the edge, while the drive roller assembly and folding device rotate simultaneously. Finally, the folding completes the packaging process, leaving no excess, irregular packaging material, or "tails." Figure 4 A schematic diagram of a packaged roll according to the second embodiment of the present disclosure is shown.

[0065] Depend on Figure 3 and Figure 4 It can be seen that the roll packaging method of the embodiment of the present disclosure can avoid the phenomenon of generating excess irregular packaging material parts, i.e., small tails, at the end of packaging.

[0066] In summary, the roll-to-roll packaging machine and packaging method of the disclosed embodiments adhere the paper tail to the already wound wrapping paper after cutting, effectively preventing the paper tail from forming a "tail" along the roll axis and ensuring a smooth packaging surface. Subsequent folding of the paper tail during operation further avoids unevenness caused by unbonded paper tails, resulting in a more regular and aesthetically pleasing appearance of the wrapped roll, enhancing the overall product image.

[0067] Furthermore, by eliminating problems like curled and uneven paper tails, manual trimming of the tails is no longer necessary, reducing labor input and costs. Consequently, the packaging time for a single product is significantly shortened. In large-scale production, this effectively compresses overall production time, significantly improving packaging efficiency and increasing production capacity. Furthermore, the tails form a single unit with the already wrapped wrapping paper, creating a tighter connection between the wrapping layers and enhancing the stability of the entire package. This prevents the wrapping paper from loosening during subsequent handling and storage, effectively protecting the roll.
