Description

Technical Field

[0001] This invention belongs to the field of packaging technology, specifically an enclosing mechanism and a paper wrapping machine. Background Technology

[0002] As an important packaging and transportation carrier for welding materials, welding wire spools have high requirements for rust prevention performance during production and storage. To prevent welding wire from getting damp and rusting during storage and transportation, a layer of rust-proof paper is usually wrapped around the outside of the welding wire spool, and labels or tape are affixed to the joints of the rust-proof paper to fix and seal it.

[0003] Currently, the process of wrapping welding wire spools with anti-rust paper is mostly done manually. Operators wrap the anti-rust paper around the outside of the spool and then manually attach labels to the overlapping areas to secure it. This method is labor-intensive, inefficient, and highly dependent on the operator's skill level, easily leading to problems such as inconsistent wrapping tightness and inaccurate label placement.

[0004] Existing automated enclosing and wrapping mechanisms fix the welding wire spool to a rotating roller, and use a robotic arm to press one end of the rust-proof paper onto the outer surface of the welding wire spool. Then, the rotating roller drives the welding wire spool to rotate, and the rust-proof paper wraps around the spool under the action of a secondary roller. The surface of the secondary roller is in close contact with the outer surface of the welding wire spool, helping the rust-proof paper to smoothly wrap the spool and maintain a certain pressure. After wrapping, the automated equipment uses a cutting device to cut the rust-proof paper and joins the two ends together, completing the wrapping of the welding wire spool.

[0005] However, this automated paper wrapping technology still has some problems. Because the outer diameter of the outer rings at both ends of the welding wire spool is larger than that of the middle welding wire ring, an unconstrained free section inevitably forms at the joint after the rust-proof paper is wrapped. This free joint section is not effectively constrained during the cutting of the rust-proof paper, making it prone to deviation or lifting during labeling. Especially in automated labeling operations, insufficient fixing force can cause the rust-proof paper to loosen after labeling, fail to fully seal, or result in folds and wrinkles at the joint, affecting the packaging quality and rust-proof effect. Summary of the Invention

[0006] The purpose of this invention is to provide a closing mechanism and a paper wrapping machine to solve the problems mentioned in the prior art.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The main rotating arm drives the actuators to rotate around the wire reel.

The rotating actuators provide precise wrapping force, enabling the paper tape to smoothly wrap around and join the wire reel, reducing errors caused by manual operation. The pressure plate on the secondary rotating arm ensures close contact between the paper tape and the surface of the wire reel, effectively preventing the paper tape from loosening or deviating, ensuring the rust prevention effect and packaging quality of the wire reel.

[0023] However, there may be instances where unnecessary detailed descriptions are omitted. For example, detailed descriptions of well-known matters or repetitive descriptions of essentially the same structures may be omitted. This is to avoid unnecessarily lengthy descriptions and to facilitate understanding by those skilled in the art. Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this application and are not intended to limit the subject matter of the claims.

[0024] Please see Figures 1-4 As shown in the embodiment of the present invention, an enclosing mechanism includes a main rotating arm 1, an actuating gripper 2, and a secondary rotating arm 3. The two main rotating arms 1 are controllably rotatable. The two actuating grippers 2 perform gripping actions on their respective main rotating arms 1. The two secondary rotating arms 3 are controllably rotatable, and pressure plates 31 are provided on the secondary rotating arms 3.

[0025] The two main rotating arms 1 are controllable rotating components that rotate in opposite directions. They drive the actuator grippers 2 to rotate around the welding wire reel, gripping the rust-proof paper strip and wrapping it around the reel. The two actuator grippers 2 are located on the main rotating arms 1, performing the gripping action before rotation and maintaining the gripping action during rotation, thus constraining both ends of the rust-proof paper. The auxiliary rotating arm 3 controls the rotation of the pressure plate 31, which presses the paper strip onto the surface of the welding wire reel, ensuring a tight fit between the paper strip and the reel.

[0026] Furthermore, since the diameter of the outer rings at both ends of the welding wire spool is larger than the diameter of the welding wire in the middle of the spool, and the actuator 2 needs to hold the paper tape, and the actuator 2 itself has thickness, the actuator 2 cannot send the paper tape end into the inner area of ​​the welding wire spool and make the paper tape end contact with the welding wire. At this time, the paper tape is only in a preliminary encirclement state relative to the welding wire spool, but at this time, a large area of ​​the paper tape has been confined between the two outer rings of the welding wire spool, and its posture has been initially constrained, providing a basis for subsequent secondary stable encirclement.

[0027] The width of the pressure plate 31 is smaller than the width of the welding wire area in the middle of the welding wire spool. By setting a bracket that extends radially inward relative to the welding wire spool on the main rotating arm 1, and / or deflecting the pressure plate 31 to a certain angle, the pressure plate 31 can be inserted into the inner circumference of the welding wire spool while the auxiliary rotating arm 3 avoids the main structure of the welding wire spool, drives the pressure plate 31 to rotate, and ensures that the pressure plate 31 is always in contact with the paper tape.

[0028] In a typical embodiment, at the initial stage of the enclosing mechanism, the two main rotating arms 1 extend 180°, and the two actuators 2 respectively grasp both ends of the paper tape. Subsequently, the main rotating arms 1 drive the actuators 2 to rotate around the path of the welding wire reel. Importantly, the two actuators 2 rotate in opposite directions, and each main rotating arm 1 drives the actuator 2 to rotate 90°, achieving the initial enclosing of the paper tape onto the welding wire reel.

[0029] Then, the pressing stage begins. The secondary rotating arm 3 drives the pressure plate 31 to rotate. During the rotation, the pressure plate 31 contacts the paper tape and presses it against the surface of the wire spool, ensuring that the paper tape and the wire spool are fully adhered. Importantly, the two secondary rotating arms 3 rotate in opposite directions.

[0030] It should be noted that the rotation of the pressure plate 31 extends to the joint area at both ends of the paper tape. The purpose of this pressing action is to ensure that the two ends of the paper tape are firmly joined and tightly fixed to the surface of the welding wire spool, forming a stable rust-proof seal, thereby avoiding potential problems such as loosening, wrinkling, or misalignment of the paper tape.

[0031] It should be further explained that since the main rotating arm 1 only plays a preliminary enclosing role, while the auxiliary rotating arm 3 needs to drive the pressure plate 31 to press the paper tape into contact with the welding wire spool, the auxiliary rotating arm 3 needs to avoid the actuator gripper 2 during rotation to avoid interference.

[0032] In one specific embodiment, the main rotating arm 1 is mounted on the frame, and the main shaft of the main rotating arm 1 is connected to the reducer and the motor in sequence, and is rotated in a controlled manner by the motor.

[0033] Optionally, the auxiliary rotating arm 3 can be mounted on the main rotating arm 1, or can be used as an independent rotating module relative to the main rotating arm 1.

[0034] In one embodiment, the auxiliary rotating arm 3 is an independent rotating module relative to the main rotating arm 1. The auxiliary rotating arm 3 is mounted on the frame, and the main shaft of the auxiliary rotating arm 3 is connected to the reducer and the motor in sequence, and is rotated in a controlled manner by the motor.

[0035] In one embodiment, two auxiliary rotating arms 3 are disposed on corresponding main rotating arms 1. During the rotation of the main rotating arm 1, the auxiliary rotating arms 3 rotate synchronously with the main rotating arm 1 at the corresponding angle, but during this process, the auxiliary rotating arms 3 are in an inactive state. After the main rotating arm 1 has completed its rotation, the auxiliary rotating arms 3 drive the pressure plate 31 to start rotating. After the main rotating arm 1 has rotated a certain angle, the auxiliary rotating arms 3 rotate the remaining angle until the two ends of the paper tape are joined.

[0036] In a further embodiment, the main rotating arm 1 includes an actuating cylinder 11, which extends outward to form a support arm 12. One end of the actuating cylinder 11 is hinged to the support arm 12 and the other end is hinged to the auxiliary rotating arm 3.

[0037] In its specific operation, after the gripper 2 completes its enclosing action, the actuator 11 begins to move. The actuator 11, through extension and retraction, causes the auxiliary rotating arm 3, hinged to it, to rotate relative to the main rotating arm 1. This causes the pressure plate 31 on the auxiliary rotating arm 3 to gradually approach the outer circle of the wire spool and engage the paper tape. Because the actuator 11, support arm 12, and auxiliary rotating arm 3 are hinged, the auxiliary rotating arm 3 can form a reasonable rotation trajectory around the main rotating arm 1 during its movement, allowing the pressure plate 31 to gradually apply pressure to the paper tape in a smooth and controllable manner.

[0038] In this process, the actuator cylinder 11 not only provides the driving force required for the pressing plate 31 to press, but also achieves precise control over the pressing position, pressing force and pressing rhythm through the controllability of the stroke and output force, thereby avoiding problems such as paper tape wrinkling, misalignment or excessive force caused by the instantaneous pressing of the pressing plate 31.

[0039] Furthermore, in the scheme where the auxiliary rotating arm 3 is driven by a motor, positional interference can easily occur between the motor and the various mechanisms of the main rotating arm 1. However, by controlling the movement of the auxiliary rotating arm 3 through the actuator 11, the assembly of the drive components and the enclosing mechanism can be changed from a vertical arrangement to a horizontal arrangement, making reasonable use of the cantilever rotation space of the main rotating arm 1.

[0040] Furthermore, by placing the auxiliary rotating arm 3 on the main rotating arm 1, a portion of the stroke of the auxiliary rotating arm 3 is completed by the main rotating arm 1. On the one hand, this avoids interference between the assembly position of the auxiliary rotating arm 3 and the rotation area of ​​the main rotating arm 1. On the other hand, in order to avoid interference with the welding wire spool during wire feeding, each auxiliary rotating arm 3 needs to rotate a large angle. However, with the main rotating arm 1 bearing part of the angle, each auxiliary rotating arm 3 only needs to rotate a small range of angles, significantly reducing the stroke of the auxiliary rotating arm 3.

[0041] In one specific embodiment, when the welding wire spool is fed and positioned, the central axis of the welding wire spool is located between the central axes of the two auxiliary rotating arms 3, so that the rotation path of the auxiliary rotating arms 3 is basically in contact with the outer circle of the welding wire spool.

[0042] Specifically, the enclosing mechanism ensures a clear division of labor and sequential coordination between the movement of the auxiliary rotating arm 3 and the pressure plate 31 and the enclosing action of the main rotating arm 1. First, the main rotating arm 1 completes the enclosing and positioning of the paper tape, and then the actuator 11 drives the auxiliary rotating arm 3 to complete the pressing and end-constraining of the paper tape. This method makes the transition of the paper tape from the enclosed state to the fully bonded state smoother and more controllable, improving the consistency and reliability of the paper tape pressing.

[0043] Furthermore, during the execution of the enclosing mechanism, there is a handover of control over the paper tape between the execution gripper 2 and the pressure plate 31. If the execution gripper 2 clamps the paper tape too tightly, the paper tape is prone to tearing due to bidirectional constraint when the pressure plate 31 drags the paper tape and applies pressure to the joint end. If the execution gripper 2 releases the paper tape directly when the pressure plate 31 intervenes, the paper tape is in an uncontrolled state before a stable press is formed, which can easily lead to problems such as deviation and lifting, affecting the subsequent jointing and labeling quality.

[0044] Therefore, a buffer plate 22 is provided between the two clamping plates 21 of the actuator 2, so that the clamping of the paper tape by the actuator 2 changes from rigid clamping to a flexible clamping structure with elasticity and compliance. The buffer plate 22 can limit the maximum clamping force of the actuator 2 on the paper tape while maintaining the basic clamping and positioning of the paper tape, thereby avoiding excessive constraint on the paper tape. When the auxiliary rotating arm 3 drives the pressure plate 31 to rotate and gradually take over the paper tape, the dragging force applied by the pressure plate 31 to the paper tape can cause the buffer plate 22 to undergo slight deformation or displacement, so that the clamping force of the actuator 2 on the paper tape changes adaptively, thereby realizing a smooth transition of the paper tape between the actuator 2 and the pressure plate 31.

[0045] Furthermore, the buffer plate 22 can achieve controlled release during the process of the pressure plate 31 dragging the paper tape, that is, it allows the paper tape to slide relative to the actuator gripper 2 without completely loosening the paper tape, thereby avoiding the paper tape from breaking due to excessive clamping and preventing the paper tape from deviating uncontrollably due to sudden loss of constraint.

[0046] In one specific embodiment, the actuator 2 is driven by a cylinder and has two clamping plates, with a buffer plate 22 disposed on at least one of the clamping plates. A spring is disposed between the buffer plate 22 and the clamping plate.

[0047] Furthermore, the contact end of the pressure plate 31 forms two pressing portions 311, which are separated from each other to form a clearance portion 312. The pressing portion 311 is located at the end that contacts the paper tape. The design of the pressing portion 311 ensures that when the pressure plate 31 presses the paper tape, it can constrain the paper tape to the outer surface of the wire spool to the maximum extent, so that the joint end of the paper tape and the wire spool form a firm and seamless bond. The clearance portion 312 forms a separation space between the two pressing portions 311, providing the necessary space for the subsequent labeling process. During the pressing of the paper tape, the clearance portion 312 can avoid interference between the pressure plate 31 and the label area, ensuring that the labeling mechanism 6 can smoothly intervene and accurately apply the label.

[0048] Furthermore, in automated packaging lines, the labeling process typically requires precise application of labels onto paper tape. The clearance section 312 provides additional space to prevent the pressure plate 31 from obstructing or hindering the label position, ensuring that the label can be applied to the correct position on the paper tape.

[0049] Please see Figure 1 , Figures 5-7 As shown, another aspect of the present invention provides a paper wrapping machine, including a closing mechanism, a conveyor belt 4, a transmission mechanism 5, a labeling mechanism 6, and a paper feeding mechanism 7.

[0050] Specifically, conveyor belt 4 is responsible for feeding the welding wire spool into the execution range of the enclosing mechanism, and after the enclosing mechanism completes the wrapping of the welding wire spool, it transports the wrapped welding wire spool to the next workstation.

[0051] The paper feeding mechanism 7 ensures that the anti-rust paper can continuously and stably produce the wrapping paper tape and sends the paper tape to the enclosing mechanism. The paper tape is then connected to the execution gripper 2 of the enclosing mechanism, so that the execution gripper 2 can smoothly grab both ends of the paper tape. Then the enclosing mechanism withdraws from the paper feeding mechanism 7 and continues to perform the wrapping operation around the welding wire reel.

[0052] The function of the transmission mechanism 5 is to adjust the movement trajectory of the enclosing mechanism, ensuring that the enclosing mechanism can effectively connect between the conveyor belt 4 and the paper feeding mechanism 7. The precise control of the transmission mechanism 5 enables the enclosing mechanism to move up and down and translate as needed, thereby controlling the enclosing mechanism to move to the paper feeding mechanism 7 to clamp the paper tape, and then move onto the conveyor belt 4 to perform the paper wrapping process after clamping the paper tape.

[0053] After the enclosing mechanism completes the wrapping, the labeling mechanism 6 accurately affixes the label to the paper tape. Throughout the process, the labeling mechanism 6 works in conjunction with the enclosing mechanism to ensure that each wire reel not only completes the wrapping of the paper tape but also completes the labeling and sealing process.

[0054] In some embodiments, please refer to Figure 6 and Figure 8As shown, the transmission mechanism 5 includes a lifting module 51 and a translation module 52.

[0055] The core function of the lifting module 51 is to adjust the height of the enclosing mechanism to ensure that it does not interfere with the paper feeding mechanism 7 or the wire reel during the gripping and wrapping process. The lifting module 51 mainly adjusts the position of the enclosing mechanism by moving up and down. When the gripper 2 of the enclosing mechanism grips both ends of the paper tape, it needs to move within a certain height range to ensure the gripping accuracy of the paper tape.

[0056] The main function of the translation module 52 is to control the horizontal movement of the enclosing mechanism, ensuring that the enclosing mechanism can accurately transfer between the paper feeding mechanism 7 and the conveyor belt 4. Through the control of the translation module 52, the enclosing mechanism can smoothly transfer from the position of the paper feeding mechanism 7 to the wire reel to perform the wrapping operation, ensuring that the paper tape enters the area around the wire reel at the appropriate time and accurately completes the wrapping task.

[0057] Furthermore, the lifting module 51 adjusts the height of the enclosing mechanism, while the translation module 52 adjusts the horizontal position of the enclosing mechanism, ensuring that the gripper 2 can smoothly grasp the paper tape and rotate around the welding wire reel, without interfering with other mechanical components throughout the process. When the paper feeding mechanism 7 provides the paper tape, the lifting module 51 and translation module 52 ensure that the enclosing mechanism can complete the grasping and wrapping action of the paper tape at the appropriate height and position.

[0058] In some embodiments, please refer to Figure 7 and Figure 10 As shown, the paper feeding mechanism 7 includes a second tensioning roller system 71, a guide rail 72, a first clamping table 73 and a second clamping table 74, and a shearing mechanism 75 is provided on the first clamping table 73.

[0059] Specifically, the rust-proof paper is placed on the wrapping machine in the form of a reel. One end of the rust-proof paper passes through the second tension roller system 71 and then exits through the first clamping table 73 into the paper feeding path. At this time, the second tension roller system 71 is responsible for adjusting the tension of the paper strip to ensure that the paper strip is not too loose or too tight, so as to ensure that the paper strip can be pulled out smoothly.

[0060] During the paper feeding operation, the second clamping table 74 begins to approach the first clamping table 73 along the guide rail 72 and clamps the end of the paper tape. At this time, the first clamping table 73 releases its grip on the paper tape, allowing the paper tape to move freely. After clamping the paper tape, the second clamping table 74 retracts along the guide rail 72, continuously pulling the paper tape out of the reel until the set standard length is reached.

[0061] When the pulled-out paper tape reaches the predetermined length, the first clamping table 73 re-clamps the end of the paper tape. After the paper tape length is determined and it is securely clamped, the enclosing mechanism begins to operate. The enclosing mechanism drives the actuator gripper 2 to grasp both ends of the paper tape. After the enclosing mechanism grasps both ends of the paper tape, the cutting mechanism 75 cuts the paper tape, completing the process of a standard length of paper tape being fed to the enclosing mechanism.

[0062] It should be noted that after the shearing mechanism 75 cuts the paper tape, the end of the paper tape fed from the reel is still stably held by the first clamping table 73, which can prepare for the subsequent clamping and pulling out by the second clamping table 74, thus providing a basis for the continuous automatic feeding of the paper tape.

[0063] It should be further noted that after the shearing mechanism 75 cuts the paper tape, in order for the second clamping table 74 to clamp the paper tape again, a certain distance must be maintained between the shearing mechanism 75 and the first clamping table 73. This ensures that after the shearing mechanism 75 cuts the paper tape, there is still a free end available for the second clamping table 74 to clamp. Furthermore, during the clamping process by the second clamping table 74, the blade of the shearing mechanism 75 must remain in a non-interfering position.

[0064] In one specific embodiment, as the second feeding table 74 moves closer to the first feeding table 73 on the guide rail 72, the first feeding table 73 also moves closer to the second feeding table 74 on the guide rail 72, so as to reduce the time for the paper tape to open.

[0065] In some embodiments, please refer to Figure 7 and Figure 9 As shown, the labeling mechanism 6 includes a first tension roller system 61, a label dispensing table 62, and a labeling robot 63. The adhesive side of the label is attached to the label tape, which is placed on the labeling mechanism 6 in the form of a reel. One end of the label tape passes around the first tension roller system 61 and extends out from the label dispensing table 62.

[0066] The function of the first tensioning roller system 61 is to ensure that the label tape tension is appropriate, preventing the label tape from becoming too loose or too tight. Appropriate tension ensures a stable supply of label tape to the label dispensing station 62, preventing jamming, jumping, or misalignment. The label dispensing station 62, through a drive mechanism, conveys the label tape from the label roll, primarily responsible for delivering the label tape to the appropriate position so that the labels can smoothly enter the working range of the labeling robot 63, facilitating the robot's gripping of the labels. The labeling robot 63 is responsible for accurately affixing the labels to the paper tape after gripping them.

[0067] In one specific embodiment, the labeling robot 63 includes a horizontal displacement mechanism, a vertical displacement mechanism, a rotation mechanism, and an actuator. The actuator is used to grasp and release labels. The horizontal displacement mechanism controls the horizontal movement of the actuator, enabling it to move across a large distance between the label dispensing table 62 and the welding wire reel. The vertical displacement mechanism controls the vertical movement of the actuator, ensuring it can adapt to welding wire reels of different heights and guaranteeing that the labels are accurately attached to the target position. The rotation mechanism provides the rotation function for the actuator, allowing it to switch between grasping labels in a horizontal position and attaching labels in a vertical position.

[0068] In a further embodiment, the labeling mechanism 6 has a first telescopic cylinder that extends horizontally. A second telescopic cylinder that extends vertically is located at the output end of the first telescopic cylinder. A rotating shaft is located at the output end of the second telescopic cylinder, and the rotating shaft is driven to rotate by a motor; an actuator is located on the rotating shaft.

[0069] In one specific embodiment, the labeling robot 63 is equipped with a vacuum adsorption module 64 at its actuating end. The vacuum adsorption module 64 creates a negative pressure area on the surface of the actuating end that contacts the label, causing the label to adhere tightly to the actuating end. This adsorption force allows the label to remain securely held at the actuating end of the robot, preventing the label from slipping or shifting during operation.

[0070] More specifically, when the labeling robot 63 needs to apply a label, the vacuum adsorption module 64 uses adsorption force to adhere the label to the execution end. At this time, other displacement mechanisms of the labeling robot 63 control the robot to move the label accurately to the target position. Due to the vacuum adsorption, the label can remain stable throughout the movement, and is not prone to slipping or deformation. When the labeling robot 63 reaches the target position, the vacuum adsorption module 64 maintains the adsorption force until the adhesive surface of the label is accurately attached to the paper tape. At this point, the adsorption force is released, and the label detaches from the execution end.

[0071] Please see Figure 5 and Figure 11 As shown, the conveyor belt 4 is composed of roller tracks, and the conveyor belt 4 is equipped with a limit pin 41 that can be raised and lowered vertically.

[0072] On the one hand, the limit pin 41 is a positioning device installed on the conveyor belt 4. When the conveyor belt 4 stops, the limit pin 41 plays the role of fixing the position of the welding wire spool, preventing the welding wire spool from running off-center, and avoiding the inaccuracy of subsequent wrapping operations due to unstable position.

[0073] On the other hand, the limiting pin 41 located in the paper tape wrapping area has a special function. The welding wire spool is designed with a central hole, and the limiting pin 41 can be inserted into the central hole of the welding wire spool to achieve positional constraint on the welding wire spool. During the wrapping process, the welding wire spool needs to be precisely held in a fixed position so that the paper tape can be wrapped evenly and accurately on the surface of the welding wire spool. After the limiting pin 41 is inserted into the central hole of the welding wire spool, it can effectively prevent the position of the welding wire spool from shifting during the wrapping process.
