[0027] In traditional filling machines, when a roll of packaging material 100 is about to be used up, a new roll of packaging material 100 needs to be connected with the remaining packaging material 100 in the filling machine. This work involves a series of operations, including identifying the new packaging material 100, checking its surface integrity, cutting the end of the packaging material 100, and maneuvering it around the guide rollers inside the filling machine. These operations take a long time for operators and consume a lot of physical strength. Because they consist of a series of operations with many steps and high judgment requirements, they have always been done manually.

[0028] Please refer to the reference. Figure 1 and Figure 2 This application proposes an automatic packaging material splicing device, including an automatic guide carriage 1, a rotating component 2, a gripping component 3, and an operating component 4. By integrating the automatic guide carriage 1, rotating component 2, gripping component 3, and operating component 4, the device automates the splicing process of packaging material 100. The automatic guide carriage 1 provides a moving platform, the rotating component 2 drives the packaging material 100 to rotate, the gripping component 3 pulls the uncoiled end of the packaging material 100, and the operating component 4 includes an operating table 41 for placing the uncoiled end of the packaging material 100 and a cutting component 42 for cutting the end of the packaging material 100. This effectively solves the problems of numerous manual operation steps, long time consumption, and high physical labor costs in the splicing process of packaging material 100 in a filling machine.

[0029] The automated guided vehicle 1, serving as the mobile carrier of the device, can be configured with a wheeled drive mechanism, using motors to drive the wheels for ground movement. For example, the automated guided vehicle 1 can employ a differential drive system, controlling the speed difference between the left and right wheels to achieve steering. Alternatively, the automated guided vehicle 1 can employ an omnidirectional wheel drive system, enabling translation and rotation in any direction. The automated guided vehicle 1 carries all other components, enabling it to move to different packaging material 100 storage locations or next to the filling machine.

[0030] The rotating assembly 2 is mounted on the automated guided vehicle 1 and is adapted to roll against the packaging material 100 to drive the packaging material 100 to rotate. In one implementation, the rotating assembly 2 may include one or more rollers that are driven to rotate by a motor. When the rollers contact the outer surface of the packaging material 100, the rotational force of the rollers is transmitted to the packaging material 100 through friction, thereby causing the packaging material 100 to rotate about its central axis. For example, the rollers may be configured to be fixed to the automated guided vehicle 1, and the movement of the automated guided vehicle 1 brings the rollers into contact with the packaging material 100.

[0031] One end of the gripping component 3 is mounted on the automated guided vehicle 1, and the other end is adapted to grip and pull the unwound end of the packaging material 100. In one implementation, the gripping component 3 may include a mechanical clamp that pneumatically or electrically drives the gripper 44 to open and close, thereby clamping the unwound end of the packaging material 100. This mechanical clamp can be mounted on a linear guide rail 431 and moved in a straight line by a linear actuator (e.g., a lead screw or synchronous belt), thereby achieving the pulling of the packaging material 100.

[0032] The operating component 4 includes an operating table 41 and a cutting component 42. The operating table 41 is mounted on the automatic guide trolley 1 and is used to place the uncoiled end of the packaging material 100. The cutting component 42 is mounted on the operating table 41 and is used to cut the end of the packaging material 100. The gripping component 3 is adapted to pull the uncoiled end of the packaging material 100 to the operating table 41, or to pull the packaging material 100 on the operating table 41 to the filling machine. Alternatively, the operating table 41 can be a metal plate with a flat surface treated to reduce friction, facilitating the sliding of the packaging material 100. The cutting component 42 can be a blade fixedly mounted on the edge of the operating table 41. When the packaging material 100 is pulled under the blade, a vertical drive mechanism presses the blade down, completing the cutting of the packaging material 100. After gripping the uncoiled end of the packaging material 100, the gripping component 3 moves to a designated position on the operating table 41 for cutting. After the cutting is completed, the gripping component 3 can grip the processed packaging material 100 end again and pull it to the feed port of the filling machine to complete the preparation work before splicing.

[0033] This device uses an automated guided vehicle 1 to provide a mobile platform, a rotating component 2 to position the packaging material 100, a gripping component 3 to grip and pull the uncoiled end of the packaging material 100, and an operating component 4 to cut the end of the packaging material 100. This automates the traditional manual operation, which involves numerous steps, long processing times, and high physical exertion. Therefore, this device effectively solves the problems of complex, time-consuming, and labor-intensive manual operation during the splicing of packaging material 100 in filling machines, improving the efficiency of packaging material splicing, achieving preset accuracy, and reducing the physical exertion of operators.

[0034] According to one embodiment of this application, the operating component 4 further includes a clamping member 43, which is disposed on the operating table 41, and the packaging material 100 is clamped between the clamping member 43 and the operating table 41.

[0035] For example, the clamping component 43 is a mechanism used to apply pressure to the packaging material 100, generating sufficient friction or directly mechanically fixing it to the operating table 41, thereby preventing displacement of the packaging material 100 during operation. Its core function is to provide a stable clamping force, ensuring the positional accuracy of the packaging material 100 during operations such as cutting and traction. For instance, the clamping component 43 can be a pneumatically or hydraulically driven pressure plate, driven downwards by a cylinder to firmly press the packaging material 100 onto the operating table 41. This method can provide a large clamping force and is suitable for packaging materials 100 of different thicknesses and materials.

[0036] Placing the clamping component 43 on the operating table 41 means that the clamping component 43 is directly associated with the placement area of ​​the packaging material 100. This layout ensures that the clamping component 43 can directly act on the packaging material 100, immediately securing it after it is placed on the operating table 41, thus providing stable support and positioning for the packaging material 100 before subsequent processing (such as cutting). This direct setup simplifies the securing process and improves the immediacy and effectiveness of the operation.

[0037] Through the above technical solution, the operating component 4 can effectively solve the problem of the packaging material 100 moving due to lack of fixation when placing and cutting the unwound end of the packaging material 100. For example, when the unwound end of the packaging material 100 is pulled to the operating table 41, the clamping component 43 can quickly activate, firmly clamping the packaging material 100 between itself and the operating table 41. This clamping action provides stable support and positioning for the packaging material 100, preventing it from sliding or shifting when the cutting component 42 performs end cutting.

[0038] According to one embodiment of this application, a clamping member 43 is movably disposed on an operating table 41. The clamping member 43 is adapted to clamp the packaging material 100 relative to the operating table 41 so that the end of the packaging material 100 is close to the cutting member 42.

[0039] For example, the clamping component 43 is movably disposed on the operating table 41, meaning that the clamping component 43 is not fixed to a certain position on the operating table 41, but can be displaced along the operating table 41. For example, the clamping component 43 can be mounted on one or more linear guides, achieving smooth linear motion through a slider or roller mechanism. The mechanism driving this movement can be a lead screw and nut mechanism driven by a stepper motor or servo motor, or a transmission system consisting of a synchronous belt and pulleys. This movable arrangement provides a basis for subsequent precise position adjustment of the packaging material 100.

[0040] By moving the packaging material 100 as described above, the end of the packaging material 100 can be brought closer to the cutting component 42. The purpose is to accurately position the unwound end of the packaging material 100 within the working area of ​​the cutting component 42. For example, the position of the end of the packaging material 100 can be detected by setting a sensor (such as a photoelectric sensor, a vision sensor, or a limit switch) and the position information can be fed back to the control system. The control system drives the pressing component 43 to move according to the preset cutting position until the end of the packaging material 100 reaches the optimal cutting position, thereby facilitating the precise cutting operation of the cutting component 42.

[0041] According to one embodiment of this application, the clamping component 43 includes: a first driving member, a slide rail 431, a clamping member 432, and a second driving member 433. The first driving member is located on the operating table 41 and its function is to provide a precise power source for the slide rail 431, enabling it to move along a preset path and distance, thereby ensuring that the end of the packaging material 100 is accurately guided to the predetermined position of the cutting component 42. The first driving member can be implemented in various forms. For example, it can be a servo motor, which, by precisely controlling its rotation angle and speed, works in conjunction with a lead screw or rack and pinion mechanism to achieve precise linear movement of the slide rail 431; alternatively, it can be a stepper motor, whose step angle is controlled by pulse signals to drive the slide rail 431 to perform quantitative displacement; or it can be a cylinder or hydraulic cylinder, which, by controlling the on / off state and flow rate of air or hydraulic pressure, drives the slide rail 431 to perform reciprocating linear motion.

[0042] The slide rail 431 is movably mounted on the operating table 41 and connected to the first driving member, which drives the slide rail 431 to move closer to or away from the cutting component 42. The function of the slide rail 431 is to provide a stable linear movement path for the clamping component 432, ensuring that the packaging material 100 does not shift or jitter when clamped and moved, thereby guaranteeing cutting accuracy. For example, the slide rail 431 can be a linear guide, such as a ball bearing linear guide, which has high precision and low friction characteristics, ensuring that the clamping component 432 moves smoothly and accurately on the operating table 41; alternatively, it can be a dovetail guide, which provides stable guidance and load-bearing capacity through its unique geometry.

[0043] A clamping member 432 is disposed on the slide rail 431, and the packaging material 100 is clamped between the clamping member 432 and the operating table 41. The function of the clamping member 432 is to directly contact the packaging material 100 and firmly fix it above the operating table 41, preventing the packaging material 100 from shifting during movement and cutting, and ensuring the accuracy of cutting. The clamping member 432 can be a pneumatic gripper 44, which is driven by air pressure to open and close, realizing the rapid clamping and release of the packaging material 100; or it can be a mechanical clamp, which realizes the clamping action under the action of the second driving member 433 through a linkage mechanism or cam mechanism.

[0044] The second driving member 433 is connected to the clamping member 432. The second driving member 433 drives a portion of the clamping member 432 to move closer to or further away from the packaging material 100 to clamp or release the packaging material 100. The function of the second driving member 433 is to achieve automated clamping and releasing of the packaging material 100, improve operational efficiency, reduce manual intervention, and ensure the stability and consistency of the clamping force. The second driving member 433 can be a small cylinder that controls the airflow direction to drive the moving part of the clamping member 432 to open and close.

[0045] Through the above technical solution, the first driving component precisely drives the slide rail 431 to move on the operating table 41, so that the clamping component 432 can stably and accurately pull the uncoiled end of the packaging material 100 to the predetermined position of the cutting component 42. The second driving component 433 is responsible for precisely controlling the clamping and releasing of the packaging material 100 by the clamping component 432, ensuring that the packaging material 100 is always firmly fixed during the movement, avoiding displacement caused by unstable clamping.

[0046] like Figure 2 As shown, according to one embodiment of this application, the operating component 4 further includes a fixing structure. The fixing structure includes a gripper 44, which is disposed on the operating table 41 and located above the operating table 41, and is used to grip the packaging material 100; and a third driving member 45, which is connected to the gripper 44 and is used to drive the gripper 44 to move up and down.

[0047] The fixing structure is a mechanism used to stabilize and fix the packaging material 100 in the vertical direction. Its main function is to temporarily fix the packaging material 100 after the gripping component 3 has completed the initial traction of the unwinding end of the packaging material 100, thereby allowing the gripping component 3 to adjust its position or perform other operations. This structure can be implemented in various forms. For example, it can be a frame-type support system integrated on the operating table 41, which has adjustable fixing units; or it can be an independent module connected to the operating table 41 via a robotic arm or guide rail system, which can be adjusted according to the size and position of the packaging material 100.

[0048] The gripper 44 is the core component of the fixing structure, used to directly clamp the packaging material 100. The gripper 44 is located above the operating table 41 to ensure effective fixing of the packaging material 100 from above. The gripper 44 can be implemented in ways including but not limited to using a pneumatic or hydraulically driven gripper, and its clamping surface can be covered with a soft material to avoid damaging the packaging material 100.

[0049] The third driving member 45 is connected to the gripper 44, and its function is to drive the gripper 44 to perform lifting and lowering movements. This lifting and lowering capability allows the gripper 44 to adapt to packaging materials 100 of different thicknesses or heights and to precisely adjust the gripping position. By introducing a fixing structure, this application effectively solves the problem that the gripping component 3 needs to move from the side of the packaging material 100 facing away from the operating table 41 to the side facing the operating table 41 for gripping during operation. For example, when the gripping component 3 pulls the unwound end of the packaging material 100 to the operating table 41, the gripper 44 in the fixing structure, driven by the third driving member 45, can precisely descend and grip the packaging material 100, thereby stably fixing the packaging material 100 above the operating table 41. In this fixed state, the gripping component 3 can temporarily release the packaging material 100 and flexibly adjust its position, moving from the back side of the packaging material 100 to the front side. Subsequently, the gripping component 3 can re-grip the side of the packaging material 100 facing the operating table 41 to facilitate the transfer of the packaging material 100 to the filling machine or for subsequent splicing operations. This design not only avoids manual intervention and improves the level of automation, but also ensures the accuracy and reliability of the gripping component 3 when gripping from different sides by stably and vertically fixing the packaging material 100, thereby improving the efficiency and success rate of splicing the packaging material 100.

[0050] According to one embodiment of this application, the aforementioned fixing structure further includes a bending member 46 and a fourth driving member 47. The bending member 46 is located at one end of the operating table 41, below the uncoiled end of the packaging material. The bending member 46 is a structural component used to support, abut, or bend the packaging material 100. For example, the bending member 46 can be a metal plate fixed to the edge of the operating table 41, with one end located below the packaging material 100, forming a supporting surface. When the bending member 46 is raised, it can form a right angle with the table surface of the operating table 41. The fourth driving member 47 is connected to the bending member 46. The fourth driving member 47 drives the bending member 46 to abut against the bottom surface of the packaging material 100 and lifts the packaging material 100. The fourth driving member 47 is an actuator for driving the movement of the bending member 46. For example, the fourth driving member 47 can be a cylinder or a hydraulic cylinder, driving the bending member 46 to perform linear reciprocating motion through the extension and retraction of the piston rod, achieving abutment and lifting.

[0051] Through the above technical solution, in the fixed structure of the operating component 4, by introducing a bending component 46 and a fourth driving component 47, the bending component 46 is located at one end of the operating table 41 and below the packaging material 100, and the fourth driving component 47 drives the bending component 46 to abut against the bottom surface of the packaging material 100 and lift the packaging material 100. The lifting effect of the bending component 46 can lift the packaging material 100 after cutting, making it easier for the gripping component 3 to grip the packaging material 100, or by cooperating with the operating table 41, bend the end of the packaging material 100 into a right angle to meet the requirements of the packaging material splicing structure, further optimizing the automated splicing process.

[0052] According to one embodiment of this application, the operating component 4 further includes a collection box 48, which is disposed on the automated guided vehicle 1 and located below the cutting component 42.

[0053] For example, the collection bin 48 is a container for collecting waste or debris, designed to hold the end waste of the packaging material 100 cut off by the cutting component 42. The collection bin 48 can be an open box structure made of metal, plastic, or other durable materials, with sufficient internal space to hold a certain amount of waste; for example, it can be an open-top container or one with an openable lid. The collection bin 48 is located on the automated guided vehicle 1 to ensure that it can move with the automated guided vehicle 1, enabling centralized management and transportation of waste. The collection bin 48 can be securely fixed to the body structure of the automated guided vehicle 1 by bolts, welding, or clips to ensure its stability during movement. Located below the cutting component 42, the collection bin 48 utilizes gravity to allow the waste generated by the cutting component 42 to fall naturally into the collection bin 48, preventing scattering. The opening or inlet of the collection bin 48 can be directly below the cutting component 42, ensuring that the cut waste falls vertically and accurately into the collection bin 48.

[0054] like Figure 3As shown, according to one embodiment of this application, the rotating assembly 2 includes a telescopic member 21 and a friction wheel 22. The telescopic member 21 is disposed on the automated guided vehicle 1. The telescopic member 21 is a mechanical structure capable of changing its length or position, typically achieved through telescopic movement. For example, the telescopic member 21 can be a cylinder or hydraulic cylinder, with a piston rod extended or retracted by pneumatic or hydraulic pressure, thereby driving the friction wheel 22 connected thereto to move. The telescopic member 21 provides the friction wheel 22 with adjustable radial or lateral movement capability, enabling it to precisely contact or separate from the surface of the packaging material 100. The friction wheel 22 is rotatably disposed on the telescopic member 21. The friction wheel 22 is a wheel-shaped component with a certain coefficient of friction, which transmits power or drives the movement of another object by contacting and rotating with the surface of another object using friction. As the component that directly contacts the packaging material 100 and applies rotational force, the design and material selection of the friction wheel 22 directly affect the driving efficiency and the protection of the packaging material 100. The telescopic member 21 is adapted to extend and drive the friction wheel 22 to move, so that the friction wheel 22 abuts against the packaging material 100.

[0055] Through the above technical solution, the telescopic component 21 is installed on the automated guided vehicle 1, providing an adjustable mounting base for the friction wheel 22. The telescopic component 21 can extend or retract precisely, driving the friction wheel 22 to move, thereby enabling the friction wheel 22 to dynamically adjust according to the actual position of the packaging material 100, achieving precise contact with the packaging material 100.

[0056] According to one embodiment of this application, the rotating assembly 2 further includes a first identification element 23, which is disposed on the automated guided vehicle 1. The first identification element 23 is used to identify the position of the packaging material 100 so that the friction wheel 22 abuts against the packaging material 100.

[0057] For example, the first identification element 23 is a sensor or detection device used to detect and determine the precise position of the packaging material 100. The concept is to provide real-time, accurate position data to guide the action of subsequent mechanical components. The first identification element 23 can employ a vision sensor, such as an industrial camera combined with image processing algorithms. By acquiring and analyzing images of the packaging material 100, the edges, center lines, or specific marker points of the packaging material 100 can be accurately identified, thereby determining its position in space.

[0058] Through the above technical solution, the first identification component 23 can accurately identify the position of the packaging material 100 and feed the position information back to the control system. Based on this precise position data, the telescopic component 21 on the automated guided vehicle 1 can drive the friction wheel 22 to move accurately to the predetermined position and make precise contact with the surface of the packaging material 100.

[0059] According to one embodiment of this application, the gripping assembly 3 includes a rotating arm 31 and a gripping member 32. One end of the rotating arm 31 is rotatably connected to the automated guided vehicle 1, and the gripping member 32 is disposed at the end of the rotating arm 31 away from the automated guided vehicle 1, and the gripping member 32 is adapted to grip the unwound end of the packaging material 100.

[0060] For example, the rotating arm 31 is a robotic arm structure with a rotatable connection point, whose main function is to extend the working range of the gripping assembly 3 and adjust the posture of the gripper 32. The rotating arm 31 can be designed as a multi-joint robotic arm, for example, composed of multiple rods connected by rotary joints, each joint being independently driveable to achieve multi-degree-of-freedom movement, enabling it to flexibly reach the unwinding end of the packaging material 100 at different positions and angles. Alternatively, the rotating arm 31 can also be a single-arm structure, rotating through its connection point with the automated guided vehicle 1, and combined with a telescopic or pitching mechanism to adjust the position and posture of the gripper 32.

[0061] Through the above technical solution, the gripping component 3 incorporates a rotating arm 31 and rotatably connects it to the automated guided vehicle 1, thereby achieving significant degrees of freedom of movement. The rotating arm 31 can rotate around its connection point, greatly expanding the working range of the gripper 32. It can adapt to the unwinding end of the packaging material 100 at different positions and angles around the filling machine. When the rotating arm 31 rotates, the gripper 32 can approach the target with a larger arc or more precise adjustments, significantly improving the positioning accuracy and success rate of the gripping operation.

[0062] According to one embodiment of this application, the gripping component 32 is provided with a suction cup 33, which is used to adsorb the unwound end of the packaging material 100; the gripping component 3 also includes a second identification component 34, which is used to identify the material information of the packaging material 100.

[0063] For example, the suction cup 33 on the gripper 32 is a device that uses internal and external pressure differences to adsorb onto the surface of an object. Its function is to achieve a firm and non-destructive grip on the unwound end of the packaging material 100 through a negative pressure adsorption mechanism, effectively avoiding problems such as slippage, displacement, or damage to the packaging material during traction. The suction cup 33 can be in the form of a pneumatic suction cup 33, which generates negative pressure by connecting a vacuum pump or a Venturi generator, creating a region inside the suction cup 33 with a pressure lower than the external atmospheric pressure, thereby tightly adsorbing the unwound end of the packaging material. The suction cup 33 can be made of materials with good flexibility and sealing properties, such as silicone, nitrile rubber, or polyurethane, to adapt to packaging materials with different materials and surface characteristics, ensuring the stability and reliability of the adsorption. Furthermore, the number and arrangement of the suction cups 33 can be optimized according to the size and shape of the unwound end of the packaging material 100 to provide sufficient adsorption force and evenly distribute stress.

[0064] Meanwhile, the grasping component 3 also includes a second identification element 34, which is a device or system for automatically acquiring packaging material-related information. Its function is to achieve automated identification of material information such as packaging material type, specifications, batch, production date, and quality status, thereby reducing the need for manual inspection and improving operational accuracy and efficiency. For example, the second identification element 34 can be implemented using various technologies. For instance, it can be a visual recognition system, including one or more cameras, an image acquisition module, and an image processing unit, which acquires the required material information by performing image recognition and analysis on barcodes, QR codes, text, or specific patterns printed on the surface of the packaging material 100. As another example, the second identification element 34 can be a radio frequency identification (RFID) reader; when an RFID tag is pre-attached to the packaging material 100, the reader can wirelessly read the material information stored in the tag.

[0065] The above technical solution is illustrated below with a more specific example: In a production facility, when a roll of packaging material in a filling machine is about to run out, the system issues a command to replace the packaging material.

[0066] Automated Guided Vehicle 1 Movement and Packaging Material Identification: The automated packaging material splicing device autonomously moves to the side of the new packaging material 100 roll. The second identification element 34 on the gripping component 3 scans the new packaging material 100 to obtain its material information and confirm that it meets production requirements. This step replaces manual identification and inspection of the packaging material 100.

[0067] Packaging material positioning and rotation: The automated guided vehicle 1 adjusts its position so that the rotating assembly 2 is close to the packaging material 100 roll. The first identification element 23 on the rotating assembly 2 detects the position of the packaging material 100 roll. Subsequently, the telescopic element 21 of the rotating assembly 2 extends, causing the friction wheel 22 to come into contact with the outer surface of the packaging material 100 roll. The friction wheel 22 begins to rotate to locate the unwound end of the packaging material 100.

[0068] Unwinding end gripping: The rotating arm 31 of the gripping component 3 extends and rotates, and the gripping part 32 at its end is equipped with a suction cup 33, which is close to the unwinding end of the packaging material 100. The suction cup 33 is activated to attract and grip the unwinding end of the packaging material 100.

[0069] Packaging material is pulled to operating table 41: The gripping component 3 pulls the unwound end of the gripped packaging material 100 and moves it to the operating table 41 on the automated guided vehicle 1. The unwound end of the packaging material 100 is placed on the operating table 41.

[0070] Packaging material fixing and cutting: The clamping component 43 of the operating assembly 4 is activated. The clamping component 43 includes a first driving member, a slide rail 431, a clamping member 432, and a second driving member 433. The first driving member drives the slide rail 431 to move, causing the clamping member 432 to approach the packaging material 100 on the operating table 41. The second driving member 433 drives the clamping member 432 to clamp the packaging material 100, fixing it between the operating table 41 and the clamping member 432. The clamping component 43 moves on the operating table 41, bringing the end of the packaging material 100 closer to the cutting component 42. The cutting component 42 is activated to cut the end of the packaging material 100. The cut waste falls into the collection box 48 below the operating table 41.

[0071] Vertical Fixing and Bending: The fixing structure includes a gripper 44 and a third drive member 45. The third drive member 45 drives the gripper 44 to descend, clamping the packaging material 100 on the operating table 41 to provide additional fixation. Simultaneously, the fixing structure also includes a bending member 46 and a fourth drive member 47. The fourth drive member 47 drives the bending member 46 to rise from below the operating table 41, abutting against the bottom surface of the packaging material 100 and lifting the uncoiled end of the packaging material 100 for pre-bending, preparing it for subsequent splicing or guiding.

[0072] Packaging material is pulled to the filling machine: After the end processing is completed, the gripping component 3 grips the unwound end of the packaging material 100 again and pulls it from the operating table 41 to the filling machine to dock with the remaining packaging material in the filling machine.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
