The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Figure 1 This is a three-dimensional structural diagram of the paper separating and transferring mechanism of a paper gluing machine according to an embodiment of this application. The illustrated paper separating and transferring mechanism, applied to a paper gluing machine, utilizes a planetary gear set to drive the deflection wheel shaft to rotate in the opposite direction of the planetary gear set's rotation as the deflection wheel shaft moves along the clearance groove. This keeps the swing arm upright, driving the material-taking component to move vertically in an arc shape, and enabling the material-taking component to carry the sheets of paper separated from the hopper in a vertically arc shape. This achieves the beneficial effects of separating and transferring paper, ensuring that only one sheet of paper is taken each time, guaranteeing the orderly operation of the entire machine, and improving production efficiency.

[0038] Please see Figures 1 to 9 The paper separating and transferring mechanism of the paper pasting machine according to this application embodiment includes a frame 100, a material handling assembly 200, a deflection wheel shaft 300, a planetary gear set 400, and a cam drive assembly 500. In this embodiment, a clearance groove 111 is provided on the side plate 11 of the frame 100. The deflection wheel shaft 300 is movably installed in the clearance groove 111. One axial end of the deflection wheel shaft 300, which passes through the clearance groove 111 and extends outward, is fixedly connected to the swing arm 21 of the material handling assembly 200. The other axial end of the deflection wheel shaft 300 is drive-connected to the planetary gear set 400. The end of the planetary gear set 400 away from the connection with the deflection wheel shaft 300 is movably connected to the side plate 11 through a connecting shaft 41. The cam drive assembly 500 is drive-connected to the planetary gear set 400.

[0039] The cam drive assembly 500 is used to drive the planetary gear set 400 to rotate around the connecting shaft 41 as the central axis, so that the deflection wheel shaft 300 moves in an arc.

[0040] In this embodiment, the arc-shaped movement trajectory of the deflection wheel shaft 300 matches the arc-shaped trajectory of the clearance groove 111. That is, during the arc-shaped movement, the deflection wheel shaft 300 moves along the clearance groove 111. The arc-shaped movement trajectory of the deflection wheel shaft 300 lies on the circle of rotation of the planetary gear set 400, which is a circle with the connecting shaft 41 as its center and the length of the planetary gear set 400 as its radius. In this embodiment, the transmission connection between the deflection wheel shaft 300 and the planetary gear set 400 is achieved by setting corresponding ball bearings at the connection point. This ensures that the deflection wheel shaft 300 and the planetary gear set 400 are in a fixed connection state in the axial direction. That is, during operation, the deflection wheel shaft 300 does not move relative to the planetary gear set 400 in the axial direction, but the deflection wheel shaft 300 can be driven by the planetary gear set 400 to rotate around its central axis. In this embodiment, the cam drive assembly 500 lifts... Power is supplied to drive the planetary gear set 400 to rotate around the connecting shaft 41, which in turn drives the deflection wheel shaft 300 to move in an arc (that is, along the clearance groove 111). This causes the material picking component 200 connected to the deflection wheel shaft 300 to follow an arc-shaped trajectory during the picking and conveying of paper. In this embodiment, the connecting shaft 41 connects the planetary gear set 400 to the side plate 11. In some optional embodiments, the connecting shaft 41 is provided with a ball bearing at the connection point with the planetary gear set 400. The connecting shaft 41 and the side plate 11 are rotatably connected by a rotatable pin. This allows the connecting shaft 41 to be connected to both the planetary gear set 400 and the side plate 11, while also enabling the connecting shaft 41 to rotate relative to both the planetary gear set 400 and the side plate 11. Thus, when the connecting shaft 41 is rotated by providing corresponding power, the provided power can be transmitted to the planetary gear set 400, thereby enabling the planetary gear set 400 to drive the deflection wheel shaft 300 to rotate around its central axis.

[0041] As the deflection wheel shaft 300 rotates and moves in an arc (along the clearance groove 111) following the planetary gear set 400, the planetary gear set 400 also drives the deflection wheel shaft 300 to rotate in the opposite direction of the planetary gear set 400's rotation, so that the swing arm 21 remains in an upright state and drives the material taking component 200 to move vertically in an arc.

[0042] In this embodiment, when the deflection wheel shaft 300 moves in an arc shape under the power provided by the cam drive assembly 500, the deflection wheel shaft 300 also rotates in the opposite direction of the planetary gear set 400 due to the reverse rotation power provided by the planetary gear set 400. For example, when the deflection wheel shaft 300 moves in an arc shape under the power provided by the cam drive assembly 500 and deflects 10° clockwise, the planetary gear set 400 provides the corresponding power to drive the deflection wheel shaft 300 to rotate 10° counterclockwise. In this way, the swing arm 21 installed on one end of the deflection wheel shaft 300 and used to connect the picking assembly 200 is always in a deflected state in space, thereby maintaining the vertical state and pulling or lifting the picking assembly 200. This ensures that the picking assembly 200 is always in the initial horizontal state when picking up paper throughout the entire paper picking and feeding process, reducing the paper being lifted up due to the deflection of the picking assembly 200, and preventing the paper from being loosened and falling off relative to the picking assembly 200 due to tilting due to being lifted up, thus ensuring effective paper picking and feeding.

[0043] The feeding assembly 200 is used to carry the sheets of paper picked up from the hopper (not labeled in the attached diagram) in a vertical arc motion and transfer them to the feed roller (see attached diagram). Figure 1 (The dotted part).

[0044] In the paper feeding and transferring mechanism of the aforementioned paper gluing machine, a feeding assembly 200, a deflection wheel shaft 300, a planetary gear set 400, and a cam drive assembly 500 are mounted on the frame 100. The two ends of the deflection wheel shaft 300 are connected axially to the swing arm 21 of the feeding assembly 200 and the planetary gear set 400, respectively. The planetary gear set 400 is movably connected to the side plate 11 via a connecting shaft 41, and the cam drive assembly 500 is connected to the planetary gear set 400 for transmission. The cam drive assembly 500 drives the planetary gear set 400 to rotate around the connecting shaft 41, causing the deflection wheel shaft 300 to move in an arc shape, and the deflection wheel shaft 300 follows the rotation of the planetary gear set 400. When moving in an arc, the planetary gear set 400 drives the deflection wheel shaft 300 to rotate in the opposite direction of the planetary gear set 400, so that the swing arm 21 maintains an upright state and drives the picking component 200 to move vertically in an arc, and the picking component 200 carries the paper picked from the hopper in a vertical arc, and smoothly and effectively transfers it to the feeding roller in a way that avoids double-sheet picking or paper not being fed in place. This solves the problems of easy double-sheet picking and paper picking errors in related technologies, realizes the benefits of picking paper in sheets, ensures that only one sheet of paper is picked up each time, ensures the orderly operation of the whole machine, and improves production efficiency.

[0045] It should be noted that the reference Figures 2 to 4In some optional embodiments, an arc-shaped clearance groove 111 is provided at the position corresponding to the side plate 11, so that the deflection wheel shaft 300 moves along the clearance groove 111 when it moves in an arc. When the cam drive assembly 500 drives the planetary gear set 400 to deflect and causes the deflection wheel shaft 300 to move in an arc along the clearance groove 111, the movement trajectory of the deflection wheel shaft 300 is the corresponding arc. For example, the deflection wheel shaft 300 moves from the highest vertical position (reference) Figure 2 Rotate clockwise 45° (reference) Figure 3 The deflector shaft 300 is located in the middle of the clearance groove 111), and then deflects clockwise by 45° (reference). Figure 4 During this process, the planetary gear set 400 drives the deflection wheel shaft 300 to rotate counterclockwise by 45°. After rotating counterclockwise by 45°, the swing arm 21 remains in a vertical position and moves vertically in an arc, driving the feeding component 200 to remain in the initial horizontal position throughout the entire paper feeding process, and feeding the paper during the vertical arc movement.

[0046] To achieve paper handling, refer to... Figures 1 to 6 In one embodiment, the material picking assembly 200 further includes a horizontal shaft 22 and a material picking device 23. The two ends of the horizontal shaft 22 are respectively connected to the corresponding swing arms 21. Multiple material picking devices 23 are horizontally spaced on the horizontal shaft 22. When the swing arms 21 drive the material picking assembly 200 to move vertically in an arc to the material bin, each material picking device 23 picks up a sheet of paper from the material bin. When the swing arms 21 drive the material picking assembly 200 to move vertically in an arc to the point of docking with the feeding roller, each material picking device 23 places the picked-up paper onto the feeding roller.

[0047] In some of the alternative embodiments, the paper-picking device that can pick up and put down the paper is suitable for the paper-picking device of the present application embodiment. For example, the paper-picking device 23 can be a vacuum nozzle or a vacuum suction cup. At the same time, the paper-picking device 23 is mounted on the horizontal shaft 22 by a locking buckle and is set toward the corresponding paper.

[0048] With this setup, using vacuum adsorption, as the horizontal axis 22 moves vertically in an arc shape driven by the swing arm 21, the picking device 23 adsorbs the corresponding paper, realizing the separation and picking of paper from the hopper, and then vertically in an arc shape to the feeding roller. The paper will not be lifted or tilted during the movement, and there is no need to increase the suction force to reduce the paper falling off relative to the picking device 23. The paper transfer efficiency is high and the paper empty suction rate is reduced. At the same time, it can be understood that because the swing arm 21 drives the horizontal axis 22 and the picking device 23 to move vertically in an arc shape, the picking device 23 is in a horizontal adsorption state after picking up the paper. During the paper movement, the picking device 23 only needs to provide the set suction force to adsorb the paper, without the need to adjust the suction force of the picking device 23 to ensure that the paper does not fall off, reducing the control difficulty of paper separation and transfer.

[0049] To achieve the movement of the deflection wheel shaft 300 along the clearance groove 111 and the rotation of the deflection wheel shaft 300 while the drive arm 21 is in an upright position, refer to... Figures 1 to 8 In one embodiment, the planetary gear set 400 further includes a deflection plate 42, a master planetary gear 43, a slave planetary gear 44, and a first drive belt 45. The deflection plate 42 is connected to the cam drive assembly 500 via a pivot 51 perpendicular to it. A connecting shaft 41 passes perpendicularly through the deflection plate 42 and is rotatably connected to the side plate 11. The master planetary gear 43 is movably mounted on the axial end of the connecting shaft 41 away from the side plate 11. The axial end of the deflection wheel shaft 300, away from the side plate 11, passes perpendicularly through the deflection plate 42 and is connected to the slave planetary gear 44. The deflection wheel shaft 300 is also rotatably connected to the deflection plate 42. The slave planetary gear 44 is connected to the master planetary gear 43 via the first drive belt 45. The master planetary gear 43 is also connected to a first drive unit (not shown in the figures).

[0050] The cam drive assembly 500 is used to drive the deflection plate 42 to rotate about the connecting shaft 41 via the pivot 51.

[0051] In this embodiment, the cam drive assembly 500 provides power, and the deflection plate 42 rotates about the connecting shaft 41 as the central axis. In this embodiment, a ball bearing is provided at the position where the connecting shaft 41 passes through the deflection plate 42. At the same time, the connecting shaft 41 is connected to the side plate 11 through a rotatable pin, so that the planetary gear set 400 is assembled with the side plate 11 through the connecting shaft 41. When the planetary gear set 400 is driven by the cam drive assembly 500, it can rotate about the connecting shaft 41 as the central axis.

[0052] As the deflection plate 42 rotates around the connecting shaft 41, it drives the deflection wheel shaft 300 to move in an arc.

[0053] In this embodiment, when the deflection plate 42 is rotated by the power provided by the cam drive assembly 500, the deflection wheel shaft 300 moves along an arc following the rotation of the deflection plate 42, so that the deflection wheel shaft 300 drives the swing arm 21 to move accordingly. In this embodiment, the deflection plate 42 and the cam drive assembly 500 are pivotally connected by a pivot 51, and the deflection plate 42 is provided with a mounting part connected to the pivot 51. The mounting part is located in the middle and on the side of the deflection plate 42. Thus, when the cam drive assembly 500 provides power for driving, the deflection plate 42 rotates around the position of the connecting shaft 41.

[0054] The first drive unit is used to drive the planetary gear 44 to rotate through the main planetary gear 43 and the first transmission belt 45 during the arc movement of the deflection wheel shaft 300, and drive the deflection wheel shaft 300 to rotate in the opposite direction of the rotation direction of the deflection plate 42, so that the swing arm 21 maintains the vertical state and drives the material picking assembly 200 to move vertically in an arc.

[0055] In some optional embodiments, by setting different transmission ratios between the master planetary gear 43 and the slave planetary gear 44, the first drive unit drives the deflection shaft 300 to rotate in the opposite direction by a corresponding angle during the arc movement of the deflection shaft 300. For example, when the transmission ratio is set to 1:2, if the deflection shaft 300 deflects 15° in an arc, the deflection shaft 300 rotates 30° in the opposite direction. In this embodiment, to ensure that the swing arm 21 is always in an upright state, the transmission ratio between the master planetary gear 43 and the slave planetary gear 44 is set to 1:1. It is understood that other transmission ratios can also be set, and the swing arm 21 can also be kept in an upright state by adjusting the matching structure. This application does not specifically limit the transmission ratio. The transmission ratio and matching structure that allow the deflection shaft 300 to drive the swing arm 21 to rotate to an upright state during the arc movement of the deflection shaft 300 are suitable for the embodiments of this application and belong to the solutions protected by the embodiments of this application.

[0056] Understandably, with this configuration, the cam drive assembly 500 drives the deflection plate 42 to rotate around the connecting shaft 41 as the central axis, thereby driving the deflection wheel shaft 300 to move in an arc. During the arc movement of the deflection wheel shaft 300, the transmission between the main planetary gear 43 and the slave planetary gear 44 drives the deflection wheel shaft 300 to drive the swing arm 21 to rotate in the opposite direction of the rotation of the deflection plate 42, thus maintaining the vertical state. This enables the feeding assembly 200 to move vertically in an arc and allows the feeding assembly 200 to carry the paper picked up from the hopper in a vertical arc, smoothly and effectively transferring it to the feeding roller without double sheets, avoiding the occurrence of paper falling or incomplete feeding.

[0057] To achieve cam-driven power, refer to Figures 1 to 5 , Figure 8 In one embodiment, the cam drive assembly 500 further includes a connecting rod 52, a crank 53, a first rotating shaft 54, a first auxiliary roller 55, a transmission cam 56, a second rotating shaft 57, and a first transmission member 58. The first rotating shaft 54 ​​is rotatably connected to the side plates 11 located on both sides of the frame 100. Cranks 53 are rotatably connected to the first rotating shaft 54 ​​at both axial ends. The end of the crank 53 away from the first rotating shaft 54 ​​is drive-connected to the connecting rod 52. The end of the connecting rod 52 away from the crank 53 is connected to the pivot 51. The first auxiliary roller 55 is located on the crank 53 near the first rotating shaft 54 ​​and is movably connected to the transmission cams 56 located at both axial ends of the second rotating shaft 57. The second rotating shaft 57 is rotatably connected to the side plates 11 and is drive-connected to the cam drive unit 600 via the first transmission member 58 located at one axial end.

[0058] The cam drive unit 600 is used to drive the first transmission component 58 to rotate the second rotating shaft 57.

[0059] It is understood that, in some of the alternative embodiments, the cam drive unit 600 that drives the first transmission member 58 to rotate the second rotating shaft 57 is suitable for the cam drive unit of the embodiments of this application. (Refer to...) Figure 6 In this embodiment, the cam drive unit 600 includes a servo motor 61 and a second transmission component 62. The second transmission component 62 is disposed on the output shaft of the servo motor 61 and is connected to the first transmission component 58 via a second transmission belt.

[0060] The second rotating shaft 57 is used to drive the transmission cam 56 to intermittently push the first auxiliary roller 55 during the rotation process, so as to drive the first rotating shaft 54 ​​to rotate and drive the crank 53 to deflect.

[0061] In this embodiment, the transmission cam 56 and the first auxiliary roller 55 are movably connected and are connected in a high-pair movable manner. At the same time, the power provided by the cam drive unit 600 is transmitted to the transmission cam 56 through the second rotating shaft 57. Then, the corresponding power is converted into the power for the first auxiliary roller 55 to rotate and drive the crank 53 to deflect. In this embodiment, the transmission cam 56 is a disc-shaped rotary cam.

[0062] The crank 53 is used to drive the pivot 51 to pull the deflection plate 42 through the corresponding connecting rod 52 during the deflection process of the crank 53 being driven to deflect, so that the deflection plate 42 rotates about the connecting shaft 41 as the central axis.

[0063] It is understandable that with this configuration, the relative movement between the transmission cam 56 and the first auxiliary roller 55 can convert the power output from the cam drive unit 600 into the power to drive the deflection plate 42 to rotate around the connecting shaft 41. At the same time, the use of a cam structure for transmission can reduce the difficulty of control. By using a cam shape that satisfies the transmission requirements, the deflection plate 42 can be driven to rotate along a set trajectory, thereby improving the accuracy and efficiency of paper separation and material transfer.

[0064] To ensure the paper remains compressed during the paper separation and transfer process, thus preventing double-sheeting, refer to... Figures 1 to 5 , Figure 9 In one embodiment, the paper separating and transferring mechanism further includes a sheet-pressing assembly 700. The sheet-pressing assembly 700 includes a second cam 71, a second auxiliary roller 72, a pivoting linkage device 73, a rocker arm 74, and pressure claws 75. The second cam 71 is mounted on a second rotating shaft 57 and is movably connected to the second auxiliary roller 72 mounted on the pivoting linkage device 73. The pivoting linkage device 73 is connected to the side plate 11 and is drively connected to the rocker arm 74. The rocker arm 74 is also provided with a plurality of pressure claws 75 spaced apart.

[0065] The second rotating shaft 57 is used to drive the second cam 71 to intermittently push the second auxiliary roller 72 during the driven rotation process, so that the pivoting linkage device 73 pivots and drives the rocker arm 74 to swing.

[0066] In this embodiment, the second cam 71 and the second auxiliary roller 72 are movably connected and are connected in a high-pair movable manner. At the same time, the power provided by the cam drive unit 600 is transmitted to the second cam 71 through the second rotating shaft 57. Then, the second cam 71 converts the corresponding power into the power that drives the second auxiliary roller 72 to pivot the pivot linkage device 73, thereby causing the rocker arm 74 to swing. In this embodiment, the second cam 71 is also a disc-shaped rotary cam.

[0067] The swing arm 74 is used to raise or lower the transmission pressure claw 75 correspondingly during the swinging process driven by the pivoting linkage 73, so as to release the paper when the paper is picked up by the paper-picking assembly 200, and to press the paper after the paper is picked up by the paper-picking assembly 200.

[0068] With this configuration, as the deflection plate 42 is rotated by the cam drive unit 600, the pressure claw 75 is simultaneously lifted or pressed down by the second rotating shaft 57, the second cam 71, the second auxiliary roller 72, the pivot linkage device 73, and the swing rod 74, ensuring that the paper is in a compressed state and there are no double sheets during the paper separation and transfer process.

[0069] To maintain stability during the swing of the pendulum 74, reference Figures 1 to 5 , Figure 9 In one embodiment, the sheet pressing assembly 700 further includes a swing arm 76, one end of which is connected to a swing rod 74, and the other end is rotatably connected to a first rotating shaft 54.

[0070] To enable the swing arm 74 to oscillate and drive the pressure claw 75 to press or release the corresponding paper, refer to... Figures 1 to 5 , Figure 9 In one embodiment, the pivoting linkage device 73 includes a first support shaft 731, a first crank 732, a first pivot block 733, and a second pivot block 734. The first support shaft 731 is disposed perpendicular to the side plate 11. One end of the first crank 732 is pivotally connected to the first support shaft 731, and the other end is pivotally connected to the first pivot block 733. A second auxiliary roller 72 is disposed on the first crank 732. The end of the first pivot block 733 away from its pivot connection with the first crank 732 is pivotally connected to the second pivot block 734. The end of the second pivot block 734 away from its pivot connection with the first pivot block 733 is connected to the rocker arm 74.

[0071] The second cam 71 intermittently pushes the second auxiliary roller 72 so that the first crank 732 swings with the first support shaft 731 as the fulcrum.

[0072] During the swinging process, the first crank 732 sequentially drives the first pivot block 733 and the second pivot block 734 to pivot, thereby causing the swing arm 74 to swing.

[0073] With this configuration, the first crank 732, the first pivot block 733, and the second pivot block 734 of the pivot linkage device 73 are pivoted accordingly, thereby converting the rotational motion of the second rotating shaft 57 into the swinging motion of the swing arm 74, so as to realize the corresponding lifting or pressing of the transmission pressure claw 75, so as to release the paper when the paper is picked up by the paper-picking assembly 200, and to press the paper after the paper is picked up by the paper-picking assembly 200.

[0074] This application also provides a paper gluing machine, including a paper separating and transferring mechanism, which is the paper separating and transferring mechanism of the paper gluing machine in the above embodiments.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
