Description

Technical Field

[0001] This application relates to the field of rewinding machines, and more particularly to a labeling device and a three-axis rewinding machine using the labeling device. Background Technology

[0002] Rewinders are key downstream equipment in the papermaking and packaging industries, used to slit large rolls of paper, film, and other materials and rewind them into smaller, more compact finished rolls. Existing rewinders have a labeling station set on the movement trajectory of the air shaft of the turntable. When the rolled paper reaches this station, it is labeled by the labeling device, and after labeling, the turntable continues to rotate to the discharge station for discharge.

[0003] The aforementioned technologies have the following drawbacks: the labeling mechanism can only complete the labeling action after the turntable has rotated and the air shaft has moved to the labeling station, resulting in low efficiency. Summary of the Invention

[0004] To improve equipment operating efficiency, this application provides a labeling device and a three-axis rewinding machine using the labeling device.

[0005] This application provides a labeling device, which adopts the following technical solution:

[0006] A labeling device, comprising a label dispensing mechanism and a label delivery mechanism, characterized in that:

[0007] The label dispensing mechanism is used to separate the labels from the label roll and convey them to the label feeding mechanism;

[0008] The label feeding mechanism includes a label suction roller for receiving labels, a label feeding power source for driving the label suction roller, and a fixed tension roller. The label feeding power source drives the label suction roller to move between the position where the label is output by the label receiving mechanism and the position where it abuts against the fixed tension roller.

[0009] By adopting the above technical solution, when this labeling device is applied to a rewinding machine, since the position of the fixed tension roller is fixed and does not rotate with the turntable, when labeling is required, the label dispensing mechanism separates the label from the label roll, and the label is adsorbed onto the label suction roller. Then, the label feeding power source drives the label suction roller to move towards the fixed tension roller. When the label suction roller comes into contact with the fixed tension roller, the label is adhered to the paper, completing the labeling action. Because the labeling process does not need to be carried out on the air shaft that rotates with the turntable, but is completed in conjunction with the fixed tension roller, the equipment does not need to stop and wait for the labeling to be completed during operation, thus resulting in higher equipment operating efficiency.

[0010] Preferably, the label feeding mechanism further includes a label feeding bracket that is driven to move by the label feeding power source, and the movable tension roller is mounted on the label feeding bracket.

[0011] By adopting the above technical solution, the label feeding support is driven by the label feeding power source, which in turn drives the movable tension roller to move.

[0012] Preferably, the label feeding power source is a label feeding motor, the output end of the label feeding motor is connected to a label feeding screw, and one side of the label feeding bracket is formed with a connecting seat that is threadedly connected to the label feeding screw.

[0013] Preferably, the bidding mechanism includes a bidding screw installed on the frame and arranged in the front-to-back direction, a bidding motor connected to and moving along the bidding screw, a bidding bracket installed above the bidding motor, and at least two sets of bidding components installed on the bidding bracket.

[0014] By adopting the above technical solution, the number of bidding components is set to at least two sets, which enables multiple bids to be issued at one time, improving the bidding efficiency and reducing the waiting time of the suction roller when it approaches the bidding mechanism.

[0015] Preferably, the label dispensing component is located above the label suction roller, the label suction roller is a hollow cylindrical tube, and multiple rows of label suction holes are formed on one side of the label suction roller. A label suction motor that drives the label suction roller to rotate is installed on the label feeding bracket.

[0016] By adopting the above technical solution, when the distance between the end of the paper and the fixed tension roller is similar to the semi-circular arc length of the label suction roller, the label feeding power source drives the label suction roller to move until the label suction roller comes into contact with the fixed tension roller. At this time, the label suction motor drives the label suction roller to rotate at the same surface linear speed as the paper winding speed, so that the label is just partially attached to the end of the paper cut off.

[0017] Preferably, each of the bidding components includes a bidding plate, a bidding mounting plate, a waste tray, and an output motor mounted on the bidding plate. A sensor for detecting whether the label tape is being fed normally is provided on the bidding plate below the bidding mounting plate. A separation plate is installed on the side of the bidding mechanism near the label feeding mechanism on the bidding plate. A separation tip is formed on the side of the separation plate near the label feeding mechanism.

[0018] By adopting the above technical solution, the output motor drives the waste tray to rotate, causing the label tape to be wound onto the waste tray after passing through the separation plate. When the label tape passes through the separation plate, the label and paper tape on the label tape separate, allowing the label to reach the suction roller and be absorbed by the suction roller.

[0019] Preferably, the label dispensing component is located on one side of the label suction roller, and the label suction roller has a label suction hole formed on the position opposite to the fixed tension roller.

[0020] By adopting the above technical solution, the label suction hole is set on the side of the label suction roller facing the fixed tension roller, so that the label suction roller can complete the labeling action without rotation when it is used for labeling, making the device simpler.

[0021] Secondly, this application provides a three-axis rewinding machine, which adopts the following technical solution:

[0022] A three-axis rewinding machine includes a frame, a winding device, a cutting device, a discharge device located on the frame, and the aforementioned labeling device.

[0023] By adopting the above technical solutions, rapid labeling can be achieved, thereby improving equipment operating efficiency.

[0024] Preferably, the winding device further includes an upper swing arm, an upper swing pressure roller, an upper swing force source, a lower swing arm, a lower swing pressure roller, and a lower swing force source rotatably connected to the frame. The upper and lower swing arms are rotatably connected to the frame via the same shaft. Driven by the upper swing force source, the upper swing arm moves the upper swing pressure roller closer to or away from the upper side of the air shaft located at the winding station. Driven by the lower swing force source, the lower swing arm moves the lower swing pressure roller closer to or away from the lower side of the air shaft located at the winding station. The cutting device includes an upper cutting assembly and a lower cutting assembly, wherein the upper cutting assembly includes... The assembly includes an upper cutter and an upper cutting power source that drives the upper cutter. The lower cutting assembly includes a lower cutter and a lower cutting power source that drives the lower cutter. The upper cutting power source is mounted on the frame, and the upper cutter is mounted below the upper cutting power source. The cutting edge of the upper cutter faces downward and is located on the right side of the air shaft of the winding station. The right side of the cutter is tangent to the surface of the air shaft of the winding station. The lower cutting power source is mounted on the frame, and the lower cutter is mounted on the left side of the lower cutting power source. The cutting edge of the lower cutter faces left, and the upper surface of the lower cutter is tangent to the surface of the air shaft of the winding station.

[0025] By adopting the above technical solution, after the roll on the air shaft at the winding station has wound up a sufficient amount of paper, the turntable rotates, and the air shaft at the winding station rotates to the discharge station. The label feeding power source drives the label suction roller to move downwards to a position close to but not in contact with the fixed tension roller. At this time, the lower surface of the movable tension roller is lower than the upper surface of the fixed tension roller. The air shaft continues to rotate, and during this process, the upper and lower swing arm power sources drive the upper and lower swing pressure rollers to press down on the roll on the air shaft that has just arrived at the winding station. The lower cutting power source drives the lower cutter to a position that engages with the upper cutter, and simultaneously, the upper cutter moves downwards to cut the paper.

[0026] Preferably, the discharge device includes a first discharge cylinder mounted on the frame at the discharge station on the right side of the air shaft. The first discharge cylinder is a rodless cylinder, and its extension direction is along the front-rear direction. A second discharge cylinder is connected to the slider of the first discharge cylinder. The piston rod of the second discharge cylinder faces to the left, and a discharge pusher is connected to the piston rod of the second discharge cylinder. The discharge block is fixedly connected to the discharge pusher after passing through two horizontally extending oblong holes on the surface of the discharge block with bolts. The left side of the discharge block is arc-shaped. A discharge pressing roller for pressing the paper is installed above the air shaft at the discharge station on the frame. The discharge pressing roller can move up and down with the cooperation of the discharge pressing power source.

[0027] By adopting the above technical solution, after the paper is wound onto the roll of the air expansion shaft at the discharge station, the second discharge cylinder drives the unloading block to abut against the paper. After the air expansion shaft releases the roll, the first discharge cylinder unloads the roll from the air expansion shaft. The position of the unloading block can be adjusted to match the diameter of the rolled roll after winding, according to the design.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When this labeling device is applied to a rewinding machine, since the position of the fixed tension roller is fixed and does not rotate with the turntable, when labeling is required, the label dispensing mechanism separates the label from the label roll, and the label is adsorbed onto the label suction roller. Then, the label feeding power source drives the label suction roller to move towards the fixed tension roller. When the label suction roller comes into contact with the fixed tension roller, the label is adhered to the paper, completing the labeling action. Because the labeling process does not need to be carried out on the air shaft that rotates with the turntable, but is completed in conjunction with the fixed tension roller, the equipment does not need to stop and wait for the labeling to be completed during operation, thus resulting in higher equipment operating efficiency.

[0030] 2. Set the number of dispensing components to at least two sets so that multiple bids can be dispensed at once, improving dispensing efficiency and reducing the waiting time of the suction roller when it approaches the dispensing mechanism.

[0031] 3. When the distance between the end of the paper and the fixed tension roller is close to the semi-circular arc length of the label suction roller, the label feeding power source drives the label suction roller to move until the label suction roller comes into contact with the fixed tension roller. At this time, the label suction motor drives the label suction roller to rotate at the same surface linear speed as the paper winding speed, so that the label is just partially attached to the end of the cut paper.

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses a three-axis rewinding machine. The terms "up," "down," "left," and "right" used in the embodiments are schematic representations of relative directions and are not limitations on the positional relationship.

[0039] like Figure 1 As shown, the three-axis rewinding machine includes a frame 1, a winding device 2 located on the frame 1, a cutting device 3, a labeling device 4, and a discharge device 5.

[0040] like Figure 1 As shown, the winding device 2 includes a turntable 6, a drive power source for rotating the turntable 6, three air shafts 7 mounted on the turntable 6, and a winding power source for driving the three air shafts 7 to rotate. The turntable 6 is rotatably connected to the frame 1 via a central rotating shaft 8. The three air shafts 7 are evenly distributed around the circumference of the turntable 6 with their axes perpendicular to the surface of the turntable 6. For ease of description, the position of the air shaft 7 in the upper left corner of the figure is named the winding station, and the position of the air shaft 7 in the upper right corner of the figure is named the unloading station.

[0041] like Figure 1 and Figure 2As shown, the winding device 2 also includes an upper swing arm 9, an upper swing pressure roller 10, an upper swing force source, a lower swing arm 11, a lower swing pressure roller 12, and a lower swing force source, all rotatably connected to the frame 1. The upper swing arm 9 and the lower swing arm 11 are rotatably connected to the frame 1 via the same shaft. Driven by the upper swing force source, the upper swing arm 9 moves the upper swing pressure roller 10 closer to or away from the upper side of the air shaft 7 located at the winding station. Driven by the lower swing force source, the lower swing arm 11 moves the lower swing pressure roller 12 closer to or away from the lower side of the air shaft 7 located at the winding station.

[0042] like Figure 2 As shown, the cutting device 3 includes an upper cutting assembly 13 and a lower cutting assembly 14. The upper cutting assembly 13 includes an upper cutting blade 15 and an upper cutting power source 16 that drives the upper cutting blade 15. The lower cutting assembly 14 includes a lower cutting blade 17 and a lower cutting power source 18 that drives the lower cutting blade 17. The upper cutting power source 16 is mounted on the frame 1, and the upper cutting blade 15 is mounted below the upper cutting power source 16. The cutting edge of the upper cutting blade 15 faces downward and is located to the right of the air shaft 7 at the winding station. The right side of the upper cutting blade 15 is tangent to the surface of the air shaft 7 at the winding station. The upper cutting power source 16 drives the upper cutting blade 15 to move up and down to cut the paper. The lower cutting power source 18 is mounted on the frame 1, and the lower cutting blade 17 is mounted to the left of the lower cutting power source 18. The cutting edge of the lower cutter 17 faces to the left, and the upper surface of the lower cutter 17 is tangent to the surface of the air shaft 7 of the winding station. The lower cutter 17 is driven to move left and right by the lower cutting power source 18 to approach or move away from the air shaft 7 of the winding station.

[0043] like Figure 3 As shown, the labeling device 4 includes a label dispensing mechanism 19 and a label feeding mechanism 20. The label dispensing mechanism 19 includes a label dispensing screw 21 mounted on the frame 1 and arranged in the front-to-back direction, a label dispensing motor 22 connected to and moving along the label dispensing screw 21, and a label dispensing bracket 23 mounted above the label dispensing motor 22. Three sets of label dispensing components 24 are mounted on the label dispensing bracket 23. Each set of label dispensing components 24 includes a label dispensing plate 25, a label mounting plate 26, a waste tray 27, and an output motor 28 mounted on the label dispensing plate 25. Label rolls are mounted on the label mounting plate 26, and the output motor 28 drives the waste tray 27 to rotate. A sensor 29 for detecting whether the label tape is being fed normally is located on the label dispensing plate 25 below the label mounting plate 26. A separating plate 30 is mounted on the side of the label dispensing mechanism 19 near the label feeding mechanism 20 on the label dispensing plate 25. A separating tip is formed on the side of the separating plate 30 near the label feeding mechanism 20. The label tape from the label roll passes through sensor 29, then wraps around separator plate 30, and is finally wound onto waste tray 27. During operation, output motor 28 drives waste tray 27 to rotate, causing the label tape to pass through separator plate 30 and be wound onto waste tray 27. As the label tape passes through separator plate 30, the label and paper tape separate, allowing the label to be conveyed to the next station via label feeding mechanism 20.

[0044] like Figure 3 As shown, the label feeding mechanism 20 includes a label feeding power source 31 mounted on the frame 1, a label feeding slide rail 32, a label feeding bracket 33 connected to a slider on the label feeding slide rail 32, a movable tension roller 34 mounted on the label feeding bracket 33, a label suction roller 35, and a fixed tension roller 36 located above the central rotating shaft 8 and rotatably connected to the frame 1. The distance between the fixed tension roller 36 and the central rotating shaft 8 is less than the distance between the air shaft 7 and the central rotating shaft 8. The label feeding power source 31 includes a label feeding motor 37, the output end of which is connected to a label feeding screw 38. A connecting seat 39 threadedly connected to the label feeding screw 38 is formed on one side of the label feeding bracket 33. The label suction roller 35 is a hollow cylindrical tube, and multiple rows of label suction holes 40 are formed on one side of the label suction roller 35. By drawing negative pressure inside the label suction roller 35, the label is adsorbed onto the label suction holes 40 on the label suction roller 35. A label-feeding bracket 33 is equipped with a label-feeding motor that drives the label-feeding roller 35 to rotate. The label-feeding motor is a servo motor, which drives the label-feeding roller 35 to rotate. The movable tension roller 34 is located on the label-feeding bracket 33 at the lower right of the label-feeding roller 35. When the label-feeding roller 35 abuts against the fixed tension roller 36, the lower surface of the movable tension roller 34 is lower than the upper surface of the fixed tension roller 36. When the movable tension roller 34 is in its highest position, it is higher than the highest position of the air shaft 7 when it rotates with the turntable 6.

[0045] like Figure 4 As shown, the discharge device 5 includes a first discharge cylinder 41 mounted on the frame 1 at the discharge station, located to the right of the air shaft 7. The first discharge cylinder 41 is a rodless cylinder, extending in the front-rear direction. A second discharge cylinder 42 is connected to the slider of the first discharge cylinder 41. The piston rod of the second discharge cylinder 42 faces to the left, and a discharge pusher 43 is connected to the piston rod of the second discharge cylinder 42. The unloading block 44 is fixedly connected to the discharge pusher 43 after passing through two horizontally extending oblong holes on the surface of the unloading block 44 with bolts. The left side of the unloading block 44 is arc-shaped. A discharge clamping roller 45 for pressing the paper is mounted above the air shaft 7 at the discharge station on the frame 1. The discharge clamping roller 45 can move up and down with the cooperation of the discharge clamping power source.

[0046] Specific usage process:

[0047] The output motor 28 drives the waste tray 27 to rotate, so that the label tape is wound onto the waste tray 27 after passing through the separation plate 30. When the label tape passes through the separation plate 30, the label and paper tape on the label tape separate, so that the label reaches the suction roller 35 and is attracted by the suction roller 35.

[0048] After the roll on the air shaft 7 at the winding station has wound up a sufficient amount of paper, the turntable 6 rotates, and the air shaft 7 at the winding station rotates to the discharge station. The label feeding power source 31 drives the label suction roller 35 to move downwards to a position close to but not in contact with the fixed tension roller 36. At this time, the lower surface of the movable tension roller 34 is lower than the upper surface of the fixed tension roller 36. The air shaft 7 continues to rotate. During this process, the power sources of the upper swing arm 9 and the lower swing arm 11 drive the upper swing pressure roller 10 and the lower swing pressure roller 12 to press down on the roll on the air shaft 7 that has just arrived at the winding station. The lower cutting power source 18 drives the lower cutter 17 to a position that cooperates with the upper cutter 15, and at the same time, the upper cutter 15 moves downwards to cut the paper.

[0049] The cut paper continues to be wound towards the discharge station from the portion connected to the air shaft 7. When the distance between the end of the paper and the fixed tension roller 36 is close to the semi-circular arc length of the label suction roller 35, the label feeding power source 31 drives the label suction roller 35 to continue moving downwards until the label suction roller 35 abuts against the fixed tension roller 36. At this time, the label suction roller 35 rotates counterclockwise at the same surface linear velocity as the paper winding speed, so that the label is just partially attached to the cut end of the paper. The paper continues to be wound until the other part of the label is attached to the wound part of the paper, so that the paper is completely wound and fixed on the roll. The second discharge cylinder 42 drives the unloading block 44 to abut against the paper, and after the air shaft 7 releases the roll, the first discharge cylinder 41 unloads the roll from the air shaft 7.

[0050] The portion of the cut paper that connects to the air shaft 7 at the winding station is wound onto the roll of the air shaft 7 after the air shaft 7 at the winding station begins to rotate.

[0051] Example 2:

[0052] The only difference between this embodiment and Embodiment 1 is that the label-absorbing roller 35 can be in any shape other than cylindrical, and multiple rows of label-absorbing holes 40 are formed on the lower side of the label-absorbing roller 35, with the separation tip of the separation plate 30 facing the position below the label-absorbing holes 40.

[0053] In use: The output motor 28 drives the waste tray 27 to rotate, so that the label tape is wound onto the waste tray 27 after passing through the separation plate 30. When the label tape passes through the separation plate 30, the label and paper tape on the label tape are separated, so that the label reaches the position below the suction roller 35 directly opposite the suction hole 40 and is attracted by the suction roller 35.

[0054] After the paper is cut, the portion of the paper connected to the air shaft 7 at the discharge station continues to wind towards the discharge station. When the paper reaches the position of the fixed tension roller 36, the label feeding power source 31 drives the label suction roller 35 to continue moving downwards until the label suction roller 35 abuts against the fixed tension roller 36. When the label suction roller 35 abuts against the fixed tension roller 36, the label portion adheres to the tail of the paper and moves away from the label suction roller 35 along with the paper. The paper continues to wind until the other portion of the label adheres to the wound portion of the paper, so that the paper is completely wound and fixed on the roll. The second discharge cylinder 42 drives the unloading block 44 to abut against the paper, and after the air shaft 7 releases the roll, the first discharge cylinder 41 unloads the roll from the air shaft 7.

[0055] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
