[0004] After the paper roll of the automatic paper splicer is used up, a paper core remains on the paper roll holder of the automatic paper splicer. At this time, the paper core needs to be removed and a new paper roll installed.

[0005] Since paper rolls are made of fragile materials and are heavy, usually around 2 tons, manual handling is extremely physically demanding and can easily cause damage to the surface of the paper rolls.

[0006] Furthermore, the process of mounting the paper roll onto the paper roll holder typically requires two people, one to push the paper roll to maintain its position, and the other to operate the automatic splicer to clamp the paper roll using a clamping head, which is time-consuming and labor-intensive.

[0007] Although the paper cores are light and removing them is not a burden for the workers, one worker usually has to run multiple automatic splicers, and sometimes it is difficult to remove the paper cores in a timely manner.

[0008] Therefore, if you want to automatically change paper for the automatic paper splicer, you need to solve the problems of paper roll storage, movement, loading and paper core unloading at the same time. Summary of the Invention

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] The facing papers on the front and back of the gypsum board are in a rolled state before being used to clamp the gypsum slurry. The facing papers generally include a paper roll 11 and a paper core 12 in its axis. The paper core 12 is in a hollow cylindrical shape.

[0055] The structure related to paper loading and unloading in the existing automatic paper splicer 1 includes a paper roll holder 13, which usually has two paper roll holders 13, one of which is a spare. When the paper roll 11 on one paper roll holder 13 is in use, the paper roll 11 on the other paper roll holder 13 is in a standby state. When the spare paper roll 11 is activated, only the paper core 12 is left on the original paper roll holder 13, and it needs to be removed and replaced with a new paper roll 11.

[0056] Typically, the paper roll holder 13 includes two clamping heads 131 and two force arms 132. The two force arms 132 can swing around one end. The two clamping heads 131 are respectively installed at the free ends of the two force arms 132. One of the clamping heads 131 has a motor, and the other clamping head 131 has a disc brake.

[0057] The two force arms 132 can swing around a horizontal axis under the action of a hydraulic system or a motor, and can also perform linear motion along a horizontal line under the action of a hydraulic system or a motor, so as to drive the clamping heads 131 to rise, fall, approach and move away from each other, so that the two clamping heads 131 can be inserted into the interior of the paper core 12 from both ends, clamp the paper roll 11 and then lift it, so that the paper roll 11 can be lifted off the ground and suspended in the air to rotate.

[0058] Figure 1 A mechanical diagram showing the process of manually replacing a paper roll 11 is shown. A track 14 is provided below a paper roll support 13 , a track trolley 15 is mounted on the track 14 , and the paper roll 11 is usually placed beside the track 14 .

[0059] In the figure, the two clamping heads 131 have been moved away from each other and raised in advance to avoid the moving path of the rail trolley 15, and the paper core 12 is taken away directly by the staff.

[0060] The paper roll 11 is pushed onto the rail trolley 15 by a staff member, and then the rail trolley 15 is moved via the track 14 so that the rail trolley 15 and the paper roll 11 are moved between the two clamping heads 131 .

[0061] Figure 2 (a) in ~ Figure 2 (f) shows a simplified diagram of the steps of replacing the paper roll 11, wherein: Figure 2 As shown in (a), the two paper rolls 11 on the automatic paper splicer 1 are in a state where they do not need to be replaced;

[0062] like Figure 2 As shown in (b), a paper roll 11 on the automatic paper splicer 1 is about to run out;

[0063] like Figure 2 As shown in (c), the two clamping heads 131 are away from each other, and the staff removes a paper core 12 from the automatic paper splicer 1;

[0064] like Figure 2 As shown in (d), the staff pushes the new paper roll 11 between the two clamping heads 131;

[0065] like Figure 2 As shown in (e), the two clamping heads 131 are close to each other, clamping a new paper roll 11 for standby use;

[0066] like Figure 2 As shown in (f), the other paper roll 11 has been used up and needs to be replaced, and a new paper roll 11 has been used.

[0067] Since the paper roll 11 is heavy, usually about 2 tons, manual handling is extremely physically demanding. Using mechanical equipment to carry the paper roll 11 is also difficult to do stably. Because the paper roll 11 is made of paper, it cannot be directly clamped, otherwise the surface will be easily damaged. The only part of the paper roll 11 that can be clamped is the paper core 12. The specifications of the paper rolls 11 stored in a warehouse vary. Therefore, it is difficult for automated equipment to accurately align the paper core 12 and insert it into it to clamp the paper roll 11. The automated equipment can easily damage the paper roll 11 when discharging.

[0068] Furthermore, the process of installing the paper roll 11 on the paper roll holder 13 usually requires two people to perform, one of whom pushes the paper roll 11 to maintain its position, and the other operates the automatic paper splicer 1 to clamp the paper roll 11 using the clamping head 131, which is time-consuming and has high labor costs.

[0069] Meanwhile, although the paper core 12 is light and removing the paper core 12 is not a burden for the staff, one staff member usually has to operate multiple automatic paper splicers, and sometimes it is difficult to remove the paper core 12 in time.

[0070] Therefore, if you want to automatically change paper for the automatic paper splicer, you need to solve the problems of paper roll storage, movement, loading and paper core unloading at the same time.

[0071] In order to solve the above technical problems.

[0072] This specific embodiment provides an embodiment of an automatic paper changing system to solve the above technical problems.

[0073] like Figure 3 As shown, its main structure includes:

[0074] Travel system 2, used for carrying weight and walking on the ground, travel system 2 can be RGV rail vehicle or AVG intelligent vehicle;

[0075] The paper roll transfer device 3 is moved on the ground by the walking system 2. The paper roll transfer device 3 is used to carry the paper roll 11 and cooperate with the movement of the automatic paper splicer 1 to complete the loading action;

[0076] The paper roll storage 4 is used to store the paper roll 11 and ensure that the stored paper roll 11 always has a rolling movement tendency in one direction;

[0077] A paper roll feeder 5 is provided beside the paper roll storage 4 and in the rolling direction of the paper roll 11 stored in the paper roll storage 4. The paper roll feeder 5 is used to take the paper roll 11 from the inside of the paper roll storage 4 and roll it onto the paper roll transfer device 3.

[0078] The paper core transfer device 6 is moved on the ground by the walking system 2 . The paper core transfer device 6 is used to carry the paper core 12 and cooperate with the movement of the automatic paper splicer 1 to complete the movement of removing the paper core 12 from the clamping head 131 .

[0079] The automatic paper changing system completes the paper changing process through the following steps:

[0080] S1. After the spare paper roll of the automatic paper splicer 1 is activated, only the paper core 12 and about 2 meters of residual paper are left on the used paper roll.

[0081] S2, such as Figure 6 As shown, the traveling system 2 drives the paper core transfer device 6 to move to the side of the paper core 12 , and the automatic paper splicer 1 and the paper core transfer device 6 work in conjunction to remove the paper core 12 on the paper roll holder 13 .

[0082] S3, such as Figure 7 As shown, the traveling system 2 drives the paper roll transfer loader 3 to move to the side of the paper core 12 , and the automatic paper splicer 1 and the paper roll transfer loader 3 work in conjunction to move the paper roll 11 on the paper roll transfer loader 3 to the paper roll support 13 .

[0083] S4, such as Figure 8 As shown, the traveling system 2 drives the paper roll transfer loader 3 to move to the side of the paper roll feeder 5. The paper roll feeder 5 takes out a paper roll 11 from the paper roll storage 4 and rolls it onto the paper roll transfer loader 3 for standby use.

[0084] Specifically, such as Figure 4 As shown:

[0085] The traveling system 2 includes: a first sub-carriage 21 for carrying the paper roll transfer device 3;

[0086] The second sub-carriage 22 is used to carry the paper core transfer device 6 .

[0087] The paper roll transfer device 3 and the paper core transfer device 6 are moved by a first sub-carriage 21 and a second sub-carriage 22 respectively. The first sub-carriage 21 and the second sub-carriage 22 can be AVG intelligent vehicles.

[0088] Furthermore, two AVG smart cars are used in one scene, and their parking positions partially overlap, making it difficult to plan the driving paths of the two AVG smart cars.

[0089] Moreover, the price of the AVG intelligent vehicle is relatively high, while the price of the RGV rail vehicle is relatively low and it is strong and durable, and is suitable for transporting the paper roll 11 of about 2 tons. Therefore, the traveling system 2 preferably uses the RGV rail vehicle.

[0090] To this end, an optional embodiment is provided, such as Figure 5 As shown, its specific structure is described as follows.

[0091] A first track 23 is formed on the ground. The first track 23 connects the paper roll feeder 5 and each automatic paper splicer 1 . The first track 23 is used for the first sub-carriage 21 and the second sub-carriage 22 to travel.

[0092] With the arrangement direction of the multiple automatic paper splicers 1 in the workshop as the center line, the first track 23 for the first sub-vehicle 21 to travel and the first track 23 for the second sub-vehicle 22 to travel are respectively located on both sides of the automatic paper splicer 1.

[0093] Furthermore, the RGV railcar can only move on the track, and therefore, each automatic paper splicer 1 needs to be equipped with two paper roll storages 4 and paper roll feeders 5, resulting in the paper roll storages 4 and paper roll feeders 5 occupying a large amount of workshop space.

[0094] In order to solve this technical problem.

[0095] The traveling system 2 includes: a mother vehicle 24 for carrying the first sub-vehicle 21 and the second sub-vehicle 22. The top surface of the mother vehicle 24 is formed with a sub-vehicle track 241 for the first sub-vehicle 21 and the second sub-vehicle 22 to travel and capable of connecting with the first track 23;

[0096] The second track 25 is formed on the ground and connects the paper roll feeder 5 and each first track 23 . The second track 25 is used for the mother vehicle 24 to travel. The first track 23 is perpendicular to the second track 25 .

[0097] The first sub-trolley 21 and the second sub-trolley 22 can move independently or through the mother cart 24. The mother cart 24 is used to move the first sub-trolley 21 and the second sub-trolley 22 to different first tracks 23, so that the paper core transfer device 6 and the paper roll transfer device 3 can perform the actions of removing paper cores 12 and supplying paper rolls 11 to different automatic paper splicers 1.

[0098] Further:

[0099] In order to prevent the first sub-carriage 21 and the second sub-carriage 22 from colliding with the paper roll holder 13 when they move, an optional embodiment is provided below. Figure 3 As shown, its specific structure is described as follows.

[0100] A first induction switch 71 and a second induction switch 72 are formed on the ground. The first induction switch 71 is arranged beside the paper roll holder 13 of the automatic paper splicer 1, and the second induction switch 72 is arranged directly below the paper roll holder 13 of the automatic paper splicer 1. The first induction switch 71 and the second induction switch 72 are both used to sense whether there is a walking system 2 directly above them.

[0101] The first induction switch 71 and the second induction switch 72 can be photoelectric switches or metal proximity switches. When the traveling system 2 is located directly above the first induction switch 71 and the second induction switch 72 , the first induction switch 71 and the second induction switch 72 send signals.

[0102] When the first induction switch 71 sends a signal, the paper roll support 13 rises to avoid the movement of the walking system 2 and prevent the paper roll transfer device 3 or the paper core transfer device 6 from colliding with the paper roll support 13 .

[0103] When the second induction switch 72 sends a signal, the paper roll support 13 is lowered to place the paper core 12 into the working area of ​​the paper core transfer device 6 , or to move the clamping head 131 into the working area of ​​the paper roll transfer device 3 .

[0104] Further:

[0105] When a worker blocks the photoelectric switch, or the metal toe of a worker's safety shoe approaches the metal proximity switch, it is easy to cause the first induction switch 71 and the second induction switch 72 to send out an erroneous signal.

[0106] To this end, an optional embodiment is provided, and its specific structure is described as follows.

[0107] The first induction switch 71 and the second induction switch 72 are signal receivers. A signal transmitter is installed on the walking system 2. The first induction switch 71 and the second induction switch 72 detect the strength of the signal to determine whether there is a walking system 2 directly above them.

[0108] The first induction switch 71 and the second induction switch 72 can be Bluetooth signal transceivers or WIFI signal transceivers. The same transceivers are installed on the walking system 2, and the position of the walking system 2 is determined by the strength of the Bluetooth or WIFI signal.

[0109] Further:

[0110] The moving path of the walking system 2 is long and can easily intersect with the moving path of pedestrians.

[0111] A laser radar is installed on the walking system 2, and the laser radar is used to detect obstacles in the forward direction of the walking system 2.

[0112] The laser radar is used to prevent the walking system 2 from colliding with pedestrians.

[0113] like Figure 9 、 10 , 11, and 12, this specific embodiment will further illustrate the specific structure of the paper core transfer device 6:

[0114] The paper core transfer device 6 includes: a storage box 61, which is placed on the carrying surface of the walking system 2, and an opening 611 is formed on the top surface of the storage box 61;

[0115] The stripping member 63 is movably connected to the material storage box 61. The stripping member 63 has the freedom to move along a first direction and a second direction. The first direction is parallel to the axis of the paper core 12 on the clamping head 131, and the second direction is perpendicular to the axis of the paper core 12 on the clamping head 131. The movement stroke of the stripping member 63 along the first direction meets the following conditions: less than the stroke of the clamping head 131 minus the axial length of the clamping head 131, and greater than the stroke of the clamping head 131 minus two axial lengths of the clamping head 131.

[0116] The sixth driver 64 connects the stripping member 63 and the storage box 61 , and is used to drive the stripping member 63 to move along the second direction so that the stripping member 63 can contact and connect with the paper core 12 ;

[0117] The guide module 65 is capable of contacting the movable clamping head 131 of the two clamping heads 131 and moving along with the movement of the clamping head 131. The guide module 65 is elastically connected to the stripping member 63 so that the stripping member 63 moves along the first direction to the end of the stroke.

[0118] The reset module 66 connects the stripping member 63 and the guide module 65 . The reset module 66 is used to enable the stripping member 63 and the guide module 65 to return to their original positions after they have moved and when no external force acts on them.

[0119] Specifically, the stripping member 63 may be a mechanical clamping claw, and the function of the stripping member 63 is to clamp the paper core 12 .

[0120] The stripping member 63 can be moved along the first direction by the air cylinder. However, this requires that the actuator of the air cylinder and the clamping head 131 keep moving synchronously at the same time and speed, which is difficult to achieve.

[0121] However, by using the guide module 65 to drag the stripping piece 63 through the reset module 66 and the guide module 65 to move along with one clamping head 131 , the stripping piece 63 can easily move synchronously with the clamping head 131 at the same time and speed.

[0122] The paper core 12 moves synchronously with the stripping piece 63 so that one end of the paper core 12 is separated from the stationary clamping head 131, and then the stripping piece 63 moves to the end of the stroke and stops moving, and the movable clamping head 131 continues to move and separates from the other end of the paper core 12. When both ends of the paper core 12 are separated from the clamping head 131, the stripping piece 63 releases the paper core 12 and makes it fall into the interior of the storage box 61.

[0123] After the clamping head 131 is reset, the stripping member 63 and the guide module 65 are reset under the action of the resilience of the reset module 66 , and the distance between the stripping member 63 and the guide module 65 is restored.

[0124] Furthermore, when the spare paper roll 11 is activated, not only the paper core 12 but also about 2 meters of paper are left from the previously used paper roll 11 . This portion of paper also needs to be put into the storage box 61 , otherwise it will affect the operation of the automatic paper splicer 1 .

[0125] In order to guide the paper core 12 stripped by the stripping member 63 and the remaining paper therein to fall into the interior of the storage box 61 through the opening 611 , an optional embodiment is provided below, and its specific structure is described as follows.

[0126] One side of the opening 611 is located on the side of the storage box 61 away from the automatic paper splicer 1, and the other side of the opening 611 is located in the middle of the storage box 61 and is formed with a discharge plate 62. The discharge plate 62 extends upward and close to the automatic paper splicer 1. When the clamping head 131 of the automatic paper splicer 1 descends, the bottom of the paper core 12 on the paper roll holder 13 can overlap the top surface of the discharge plate 62.

[0127] When the paper core 12 rolls along the discharge plate 62 into the interior of the storage box 61 , the paper core 12 drags the paper remaining on the surface of the paper core 12 into the interior of the storage box 61 .

[0128] Furthermore, if there is a long piece of paper remaining on the paper core 12, such as about 3 meters of paper, about 1 meter of paper will overlap the edge of the opening 611 and remain outside the storage box 61. In order to solve this problem.

[0129] The bottom wall 612 inside the material storage box 61 is inclined downward and toward the automatic paper splicer 1 .

[0130] The paper core 12 rolls along the unloading plate 62 in the direction away from the automatic paper splicer 1. After the paper core 12 enters the interior of the opening 611, the paper core 12 rolls along the bottom wall 612 in the direction close to the automatic paper splicer 1 to extend the moving distance of the paper core 12 during the unloading process, thereby allowing the longer paper remaining on the paper core 12 to completely enter the interior of the storage box 61.

[0131] Optionally: In order to facilitate the staff to take out the paper core 12 collected in the storage box 61.

[0132] A movable door 613 is provided on the side of the storage box 61 at the lowest point near the bottom wall thereof.

[0133] The top of the movable door 613 is rotatably connected to the storage box 61 through a pin, and the side of the movable door 613 is fixedly connected to the storage box 61 through a latch. By pulling out the latch, the movable door 613 can be opened by the handle to take out the paper core 12 inside the storage box 61.

[0134] On the other hand, this specific embodiment further provides a stripping member 63 that is different from the clamping claws, which can not only achieve the purpose of frictionally connecting the paper core 12 , but also guide the paper core 12 to move along the stripping plate 62 .

[0135] The paper core transfer device 6 further includes a first slide post 67, which is fixedly connected to the storage box 61, and the axis of the first slide post 67 is parallel to the first direction. The stripping member 63 is connected to the first slide post 67 via a cylindrical pair.

[0136] The top surface of the stripping plate 62 is smooth, the stripping piece 63 is a claw-shaped plate, and the bottom surface of the stripping piece 63 is rough. When the stripping piece 63 rotates along the second direction, it can press the paper core 12 overlapping the top surface of the stripping plate 62, so that the stripping piece 63 is frictionally connected to the paper core 12, and the stripping plate 62 and the paper core 12 slip.

[0137] The stripping member 63 can move along the axis of the first slide post 67 or rotate around the axis of the first slide post 67 .

[0138] In order to facilitate the relative movement between the unloading plate 62 and the paper core 12, the unloading plate 62 can also be replaced by a roller table or a universal ball table.

[0139] The sixth driver 64 can adopt a cylinder. The main body of the sixth driver 64 is connected to the storage box 61 through a cylindrical pair. The executive part of the sixth driver 64 is connected to the stripping piece 63 through a cylindrical pair. The axial movement of the stripping piece 63 along the first sliding column 67 has no effect on the position of the sixth driver 64.

[0140] When both ends of the paper core 12 are separated from the clamping head 131 , the pressure transmitted to the stripping member 63 by the sixth driver 64 causes the stripping member 63 to continue to rotate downward, thereby pushing the paper core 12 to move along the discharge plate 62 into the storage box 61 .

[0141] Furthermore: since the unloading plate 62 must be offset from the stripping piece 63, the stripping piece 63 can continue to push the paper core 12 over the unloading plate 62 to make it fall. Since the two force points of the paper core 12 are not in the same position, the paper core 12 is easily pushed and flipped by the stripping piece 63, making it difficult for the paper core 12 to pass through the opening 611 and enter the storage box 61.

[0142] In order to solve this problem, an optional embodiment is provided below, and its specific structure is described as follows.

[0143] When the stripping piece 63 moves along the second direction, it does not contact the storage box 61 and the unloading plate 62. There are two unloading plates 62, and the stripping piece 63 is located between the two unloading plates 62. When the stripping piece 63 moves to the maximum stroke along the second direction, the paper core 12 on the unloading plate 62 is pushed into the interior of the storage box 61 by the stripping piece 63.

[0144] The two stripping plates 62 are used to prevent the paper core 12 from turning over.

[0145] Optionally, the reset module 66 includes a first elastic member 661 , and the first elastic member 661 is located on a side of the stripping member 63 close to the movable clamping head 131 ;

[0146] A first stop ring 671 and a second stop ring 672 are formed on the first slide column 67, and the first stop ring 671 and the second stop ring 672 are respectively located on both sides of the stripping piece 63, wherein the first stop ring 671 is close to the movable clamping head 131, and the first elastic piece 661 is mounted on the first slide column 67, and the two ends of the first elastic piece 661 are against the stripping piece 63 and the first stop ring 671.

[0147] Specifically, the first elastic member 661 is a spring, and the first elastic member 661 is used to drive the stripping member 63 to reset.

[0148] The first stop ring 671 and the second stop ring 672 are also used to limit the travel of the stripping piece 63 in the first direction. When the stripping piece 63 contacts the second stop ring 672, the stripping piece 63 is located at the starting point of its own travel. When the first elastic piece 661 is compressed to the limit, the stripping piece 63 is located at the end point of its own travel.

[0149] Furthermore: Since the stripping piece 63 has two degrees of freedom at the same time, in order to always elastically connect the stripping piece 63 and the guide module 65, the guide module 65 must also have two degrees of freedom, that is, the guide module 65 can also move along the first direction and the second direction. For this purpose, an optional embodiment of the guide module 65 is provided below, and its specific structure is described as follows.

[0150] The guide module 65 includes a guide block 651, which is in the shape of a long strip. One end of the guide block 651 is connected to the first slide column 67 through a cylindrical pair. The guide block 651 is transmission-connected to the executive part of the sixth driver 64 and rotates synchronously with the stripping member 63. When the stripping member 63 rotates along the second direction and presses the paper core 12, the free end of the guide block 651 is coaxial with the axis of the paper core 12.

[0151] When the unloading plate 62 and the stripping piece 63 clamp the paper core 12, the free end of the guide block 651 is coaxial with the axis of the paper core 12, so that when the clamping head 131 moves, the side of the clamping head 131 away from the paper core 12 can contact the guide block 651 and push the guide block 651 to move.

[0152] A rubber pad 652 is installed on one side of the guide block 651 close to the clamping head 131 . The rubber pad 652 is used to prevent the motor or disc brake installed on the clamping head 131 from being damaged by the guide block 651 .

[0153] Optionally, the middle end of the stripping member 63 is slidably connected to the guide block 651 via a second sliding post 68 , the second sliding post 68 is parallel to the first sliding post 67 , and the actuator of the sixth driver 64 is connected to the second sliding post 68 via a cylindrical pair.

[0154] The sixth driver 64 drives the stripping member 63 and the guide block 651 to move synchronously via the second slide post 68 .

[0155] Optionally, the guide block 651 and the stripping piece 63 are elastically connected via the following structure.

[0156] The reset module 66 includes a second elastic member 662 , and the second elastic member 662 is located on a side of the stripping member 63 away from the movable clamping head 131 ;

[0157] A third stop ring 681 and a fourth stop ring 682 are formed on the second slide column 68, and the third stop ring 681 and the fourth stop ring 682 are respectively located on both sides of the stripping piece 63, wherein the third stop ring 681 is close to the movable clamping head 131, and the second elastic piece 662 is mounted on the second slide column 68, and both ends of the second elastic piece 662 are against the stripping piece 63 and the fourth stop ring 682.

[0158] Specifically, the second elastic member 662 is a spring, and the second elastic member 662 is used to elastically connect the stripping member 63 and the guide module 65 so that the stripping member 63 can move along with the guide module 65 .

[0159] After the paper core 12 enters the material storage box 61 , the second elastic member 662 drives the guide module 65 to reset by the rebound force until the stripping member 63 contacts the third stop ring 681 .

[0160] like Figure 13 、 14 , 15, and 16, this specific embodiment will further illustrate the specific structures of the paper roll storage 4 and the paper roll feeder 5:

[0161] The paper roll feeder 5 includes a discharge slope 511 that is inclined downward and toward the discharge direction. The paper roll transfer device 3 can be moved to the lower end of the discharge slope 511 by the walking system 2.

[0162] The blocking belt 54 has a length and two ends, the ends of the blocking belt 54 are respectively located above and below the discharge slope 511, and the blocking belt 54 generates a damping force that can prevent the paper roll 11 from rolling down the discharge slope 511;

[0163] Wherein: both ends of the blocking belt 54 are fixedly connected to the frame, and the blocking belt 54 can be elastically retracted;

[0164] Alternatively, one end of the material blocking belt 54 is fixedly connected to the frame, and the other end of the material blocking belt 54 is slidably mounted on the frame and dampingly connected to the frame;

[0165] Alternatively, one end of the blocking belt 54 is fixedly connected to the frame, and the other end of the blocking belt 54 is wound on a rotatable belt reel 53, and the belt reel 53 is dampingly connected to the frame.

[0166] The paper roll feeder 5 can slowly remove the paper roll 11 from the paper roll storage 4 by the following three methods to prevent the paper roll 11 from being removed from the paper roll storage 4 too quickly, thereby causing the paper roll 11 and / or the paper roll transfer device 3 to be damaged.

[0167] Method 1: Both ends of the blocking belt 54 are fixedly connected to the frame. The blocking belt 54 can be elastically extended. The downward rolling movement of the paper roll 11 is hindered by the elastic force generated by the extension of the blocking belt 54.

[0168] Method 2: One end of the blocking belt 54 is fixedly connected to the frame, and the other end of the blocking belt 54 is slidably mounted on the frame through a slider. There is a large damping force between the slider and the frame that hinders the sliding of the blocking belt 54. The damping force is sufficient to hinder the downward rolling movement of the paper roll 11.

[0169] Method 3: One end of the blocking belt 54 is fixedly connected to the frame, and the other end of the blocking belt 54 is installed on the frame through the belt reel 53 so as to be reeled or released. There is a large damping force between the belt reel 53 and the frame that hinders the rotation of the belt reel 53. The damping force is sufficient to hinder the downward rolling movement of the paper roll 11.

[0170] Optionally:

[0171] The paper roll feeder 5 includes a stop block 51 and a fifth driver 52. A discharge slope 511 is formed on the top surface of the stop block 51. The fifth driver 52 is used to drive the stop block 51 to move up and down.

[0172] The paper roll storage 4 is provided with a supporting plate 44 that is tilted downward and abuts against the side wall of the stop block 51 . The supporting plate 44 is used to support multiple paper rolls 11 and enables the multiple paper rolls 11 to move toward the stop block 51 under the action of gravity.

[0173] Specifically, the paper roll storage 4 is a storage rack with a steel structure, and baffle plates 45 for abutting against the end surfaces of the paper roll 11 are provided on both sides of a carrying plate 44 .

[0174] The stopper 51 is used to prevent the paper rolls 11 stored in the paper roll storage 4 from rolling. The fifth driver 52 is a hydraulic system, which includes a guide mechanism and a hydraulic cylinder. The hydraulic cylinder is used to drive the stopper 51 to move up and down. The guide mechanism is used to guide the movement direction of the stopper 51. The stopper 51 is raised and lowered vertically so that the paper rolls 11 stored in the paper roll storage 4 are blocked by the stopper 51 or one of them rolls onto the discharge slope 511.

[0175] The belt reel 53 is rotatably connected to the frame or the blocking block 51 , and the rotation axis of the belt reel 53 is horizontal and perpendicular to the rolling direction of the paper roll 11 .

[0176] The retaining tape 54 is a braided tape.

[0177] The paper roll feeder 5 works in the following way to remove one paper roll 11 at a time from the inside of the paper roll storage 4: S1, after the fifth driver 52 drives the blocking block 51 to descend, the paper rolls 11 stored in the paper roll storage 4 roll toward the blocking block 51, and one of the paper rolls 11 rolls onto the unloading slope 511, and the paper roll 11 on the unloading slope 511 is blocked by the blocking belt 54 and stops moving.

[0178] S2 , after the fifth driver 52 drives the blocking block 51 to rise, the paper roll 11 stored in the paper roll storage 4 is blocked by the blocking block 51 , and the paper roll 11 on the unloading slope 511 has a tendency to roll away from the paper roll storage 4 .

[0179] S3 , under the obstruction of the blocking belt 54 , the belt reel 53 slowly moves onto the paper roll transfer device 3 to prevent the paper roll 11 from falling down quickly and damaging the paper roll transfer device 3 .

[0180] S4 , disconnecting the blocking belt 54 from the paper roll storage 4 , and reeling the blocking belt 54 by the belt drum 53 to separate the paper roll 11 from the blocking belt 54 , and then reconnecting the blocking belt 54 to the paper roll storage 4 .

[0181] A hook 41 is installed on the frame, and the material blocking belt 54 is connected to the hook 41 through a hanging hole 541 . The hanging hole 541 is located at the end of the material blocking belt 54 .

[0182] Furthermore, the hook 41 is connected to the frame via a third driver 42 , and the third driver 42 is used to drive the hook 41 to rotate, so that the hook 41 hooks the hanging hole 541 or releases the hanging hole 541 .

[0183] The third driver 42 can be a motor or a cylinder. The position of the third driver 42 on the paper roll storage 4 can be adjusted so that a distance is left between the hook 41 and the blocking block 51 for the paper roll 11 to pass through.

[0184] The opening of the hook 41 faces the rolling direction of the paper roll 11. When the third driver 42 drives the hook 41 to rotate toward the paper roll storage 4, the opening of the hook 41 moves downward and toward the rolling direction of the automatic paper splicer 1, so that the end of the blocking belt 54 is separated from the hook 41.

[0185] Furthermore, the third driver 42 is connected to the frame via a fourth driver (not shown in the figure), and the fourth driver is used to drive the third driver 42 to move so that the hook 41 approaches or moves away from the tape reel 53 .

[0186] The fourth driver can be a servo electric push rod, which is mainly used to drive the hook 41 to rise and fall so that the hook 41 is close to the tape reel 53, making it easier for the staff to hang the hanging hole 541 on the hook 41, and then the fourth driver 43 drives the hook 41 to reset.

[0187] Furthermore, this specific embodiment also provides an embodiment in which a motor automatically hooks the end of the material blocking belt 54 onto the hook 41 .

[0188] The belt reel 53 is driven to rotate by the motor, and the belt reel 53 is in driving connection with the output shaft of the motor;

[0189] The belt reel 53 is connected to the frame or the material block 51 through a torque sensor 532. The torque sensor 532 is used to detect the torque borne by the belt reel 53.

[0190] The blocking tape 54 is wound up by the tape reel 53 , and when the tape reel 53 continues to rewind, the hanging hole 541 performs a circular motion, and the motion trajectory of the hanging hole 541 falls within the moving stroke of the hook 41 .

[0191] The above embodiment is used to automatically hook the end of the blocking belt 54 on the hook 41. The specific working steps of step S4 are as follows: S41, the third driver 42 drives the hook 41 to rotate to disconnect the blocking belt 54 from the frame, one end of the blocking belt 54 is separated from the hook 41, and the belt reel 53 reels the blocking belt 54 so that the paper roll 11 is separated from the blocking belt 54.

[0192] S42, the fourth driver 43 drives the hook 41 to approach the tape reel 53, so that after the blocking tape 54 is completely wound up by the tape reel 53, when the tape reel 53 continues to rotate under the drive of the motor, the end of the blocking tape 54 is swung by the tape reel 53, so that the hanging hole 541 performs a circular motion, and the hook 41 is located in the motion trajectory of the hanging hole 541.

[0193] S43, the hanging hole 541 is hooked by the hook 41, the belt drum 53 stops rotating immediately, the torque output by the motor on the belt drum 53 increases instantly, the torque sensor 532 sends a signal to the controller, the controller determines that the blocking belt 54 is connected to the hook 41, the controller sends a signal to the motor and the fourth driver 43, the motor stops working, and the fourth driver 43 drives the hook 41 to reset.

[0194] On the other hand, the tape reel 53 needs to reel in the blocking tape 54 to separate from the paper roll 11 , but the paper roll 11 is heavy and it is difficult to rotate the tape reel 53 by manpower.

[0195] The damper includes a motor, and the belt reel 53 is in driving connection with an output shaft of the motor. The motor is used to drive or hinder the belt reel 53 from rotating.

[0196] The motor is a roller motor, which is built into the take-up drum 53 and is therefore not shown in the figure. The motor can output torque to the take-up drum 53 to counteract the weight of the paper roll 11, thereby reducing the rotation speed of the take-up drum 53. At the same time, the motor can also retract the material blocking belt 54 after the paper roll 11 moves to the paper roll transfer device 3.

[0197] Furthermore, the energy consumed by reducing the rotation speed of the belt reel 53 through the torque output by the motor is too much.

[0198] The damper includes a brake 531 , which is used to prevent the belt reel 53 from rotating.

[0199] The brake 531 is a disc brake, which is mounted on the rotating shaft of the tape reel 53 . Compared with a motor, the brake 531 consumes less energy to hinder the rotation of the tape reel 53 .

[0200] Furthermore, the damper includes a torque sensor 532 , which is connected to the tape reel 53 and the paper roll storage 4 or the blocking block 51 . The torque sensor 532 is used to detect the torque borne by the tape reel 53 .

[0201] When the paper roll 11 moves to the unloading slope 511, the brake 531 is in a locked state, the blocking belt 54 is stretched straight, and the belt drum 53 is subjected to a large torque. The controller determines that the paper roll 11 is on the unloading slope 511 through the signal sent by the torque sensor 532, and then the fifth driver 52 drives the blocking block 51 to rise.

[0202] When the paper roll 11 moves onto the paper roll transfer device 3, the blocking belt 54 is stretched straight, but the weight of the paper roll 11 is completely borne by the paper roll transfer device 3, and the belt drum 53 does not bear any torque. The controller determines that the paper roll 11 is on the paper roll transfer device 3 through the signal sent by the torque sensor 532. The staff unties the connection between the blocking belt 54 and the paper roll storage 4, and then the motor rotates the belt drum 53 to reel in the blocking belt 54, so that the paper roll 11 is separated from the paper roll transfer device 3.

[0203] like Figure 17 、 18 , 19, 20, this specific embodiment will further explain the specific structure of the paper roll transfer device 3:

[0204] The paper roll transfer device 3 includes: an adaptive slide 31, which is arranged on the walking system 2 and can move along a first direction, which is horizontal;

[0205] A first driver 32 is connected to the adaptive slide 31 and the walking system 2. The first driver 32 is used to drive the adaptive slide 31 back to its original position when the position of the adaptive slide 31 changes;

[0206] The paper roll supporting platform 33 is arranged on the adaptive slide 31. The paper roll supporting platform 33 is used to support the paper roll 11. When the paper roll 11 is placed on the paper roll supporting platform 33, the intersection line of the horizontal plane where the axis of the paper roll 11 is located and the curved surface where the motion trajectory of the actuator of the paper roll holder 13 is located is parallel to the axis of the paper roll 11.

[0207] The traveling system 2 is used to drive the paper roll transfer device 3 to move to the side of the automatic paper splicer 1 and to make the paper core 12 substantially located between the two clamping heads 131 .

[0208] Specifically, the executing parts of the paper roll holder 13 are the clamping head 131 and the lever arm 132 , wherein the clamping head 131 can also be regarded as the executing end of the paper roll holder 13 .

[0209] The clamping head 131 performs circular motion and linear movement under the action of the force arm 132 and the hydraulic system, so that the clamping head 131 can move along the fan-shaped curved surface. The intersection of the curved surface and the horizontal plane where the axis of the paper roll 11 is located is the intersection line of the two. When the axes of the clamping head 131 and the paper roll 11 are both located on the intersection line, the clamping head 131 can be inserted into the interior of the paper core 12.

[0210] Since in the existing paper roll 11, only one of the two force arms 132 performs linear movement under the action of the hydraulic system, when the two clamping heads 131 insert the paper core 12 and clamp the paper roll 11, the paper roll 11 will be pushed by the clamping heads 131 to move along its own axial direction. At this time, the adaptive slide 31 moves on the walking system 2, and the adaptive slide 31, the paper roll supporting platform 33 and the paper roll 11 remain relatively stationary.

[0211] After the clamping head 131 clamps the paper roll 11, the clamping head 131 rises under the action of the force arm 132 and the hydraulic system, lifting the paper roll 11, so that the paper roll 11 is separated from the paper roll supporting platform 33. The adaptive slide 31 returns to its original position under the action of the first driver 32, and the walking system 2 moves the paper roll transfer device 3 away, and the loading operation is completed.

[0212] Furthermore, after the paper roll 11 moves to the paper roll supporting platform 33, the blocking belt 54 needs to be pulled out from under the paper roll 11. During the process of pulling out the blocking belt 54, the paper roll 11 may roll and fall off the paper roll supporting platform 33, or the paper roll 11 may not roll, causing its surface to be scratched by the blocking belt 54.

[0213] In order to solve the above technical problems.

[0214] The paper roll transfer device 3 includes: a driving roller 34, which is arranged on the paper roll supporting platform 33 and can rotate, and the axis of the driving roller 34 is parallel to the first direction;

[0215] The driven roller 35 is disposed on the paper roll supporting platform 33 and is rotatable. The axis of the driven roller 35 is parallel to the axis of the driving roller 34 .

[0216] When the blocking belt 54 is wound, the paper roll 11 rotates idly on the driving roller 34 and the driven roller 35 .

[0217] In order to automatically achieve the result of aligning the axis of the clamping head 131 with the axis of the paper core 12 in the above-mentioned working steps, a controller that can link the automatic paper splicer 1, the walking system 2 and the paper roll transfer device 3 is also required, so that the automatic paper roll feeding vehicle can automatically perform the feeding action without manual operation.

[0218] To this end, an optional embodiment is provided, and its specific structure is described as follows.

[0219] A code disc (not shown) is mounted on the rotating shaft of the paper roll holder 13 , and the code disc is used to read the rotation angle of the rotating shaft.

[0220] Specifically, the hydraulic system that controls the swing of the lever arm 132 in the paper roll holder 13 is communicated with the controller. The controller reads the swing angle of the paper roll holder 13 through the code disk, and sends a stop signal to the paper roll holder 13 when the lever arm 132 swings to a specified angle, so that the lever arm 132 stops at the specified angle, and then the clamping head 131 stops at a specified height.

[0221] The paper roll holder 13 stops swinging at the following two angles: 1. An angle at which the clamping head 131 rises to the highest height to avoid the traveling system 2 .

[0222] Second, the angle at which the clamping head 131 is aligned with the axis of the paper core 12 is such that the clamping head 131 can be inserted into the paper core 12 .

[0223] The diameters of paper rolls 11 of the same specifications are the same. When the paper roll 11 is placed on the paper roll supporting platform 33, the height of the axis of the paper roll 11 is fixed. Therefore, the staff can input the diameters of paper rolls 11 of different specifications into the controller in advance, and the controller will automatically calculate the height of the axis of the paper roll 11.

[0224] Subsequently, the controller calculates the angle that the paper roll holder 13 needs to swing to make the clamping head 131 flush with the axis of the paper roll 11 based on the height of the axis of the paper roll 11, and then establishes a comparison table between the specifications of the paper roll 11 and the swing angles of the paper roll holder 13. The subsequent controller can obtain the swing angles that the paper roll holder 13 needs to swing when clamping paper rolls 11 of different specifications by looking up the table.

[0225] Furthermore, when the specifications of the paper roll 11 are changed, the diameter of the paper roll 11 changes, and the height of the axis of the paper roll 11 will also change accordingly. In this case, it is necessary to adjust the rotation angle of the lever arm 132 and / or the linear movement distance of the paper roll support platform 33 in the horizontal direction so that when the diameter of the paper roll 11 is changed, the axis of the paper roll 11 can still be aligned with the axis of the clamping head 131. To this end, it is necessary to obtain the diameter of the paper roll 11 and then modify the rotation angle of the lever arm 132.

[0226] Several optional embodiments for obtaining the diameter of the paper roll 11 are provided below.

[0227] Optionally: the paper roll transfer device 3 includes: a visual detection device (not shown in the figure), which is arranged on the walking system 2 and faces the paper roll supporting platform 33, and is used to obtain an image above the paper roll supporting platform 33 from the first direction.

[0228] The visual inspection device includes a CCD camera and an image processor. The CCD camera obtains an end surface image of the paper roll 11 on the paper roll supporting platform 33 from an axial perspective, and then obtains the diameter of the paper roll 11 through the image processor.

[0229] However, CCD cameras are greatly affected by light environment and vibration, and are easily damaged in collisions, and are not suitable for installation on the walking system 2 that moves around.

[0230] As another optional implementation of the above embodiment: the active roller 34 can actively rotate;

[0231] The driven roller 35 can be driven to rotate;

[0232] The paper roll transfer device 3 includes a distance meter, which is arranged on the paper roll supporting platform 33 and located between the active roller 34 and the driven roller 35. The distance meter is used to measure the distance between the outer peripheral surface of the paper roll 11 placed on the active roller 34 and the driven roller 35 and itself.

[0233] The figure does not show a rangefinder, which may use a laser rangefinder sensor.

[0234] The active roller 34 and the driven roller 35 are used to drive the paper roll 11 to rotate one circle, so that the distance meter can obtain the distance between each part of the paper roll 11 and itself, and obtain an average value, thereby eliminating the roundness error of the paper roll 11.

[0235] Since the distance between the active roller 34 and the driven roller 35 is fixed, the curvature of the outer circumference of the paper roll 11 and the height of its axis can be calculated by measuring the distance between the outer circumference of the paper roll 11 and the distance meter, combined with the distance between the active roller 34 and the driven roller 35.

[0236] However, when the specifications of the paper roll 11 vary greatly, causing the diameter of the paper roll 11 to vary greatly, the distance between the active roller 34 and the driven roller 35 should be adjusted so that the active roller 34 and the driven roller 35 can always better support the paper roll 11. At this time, the distance meter will no longer be applicable.

[0237] As another optional implementation of the above embodiment: the active roller 34 can actively rotate;

[0238] The driven roller 35 can be driven to rotate;

[0239] The paper roll transfer device 3 further includes: an inkjet device 36, which is disposed on the paper roll support platform 33 and located between the active roller 34 and the driven roller 35, and is used to spray dots of pigment onto the outer peripheral surface of the paper roll 11;

[0240] The detector 37 is disposed beside the inkjet 36 and is used to sense the pigment dots ejected by the inkjet 36 and send out signals.

[0241] The pigment sprayed by the inkjet 36 can gradually disappear over time, or fade at high temperatures when the gypsum board is being dried, so that the pigment sprayed by the inkjet 36 has no effect on the surface quality of the gypsum board.

[0242] The detector 37 can be a color sensor or a CCD camera. The detector 37 is communicatively connected to the controller. When the paper roll 11 rotates one circle, the pigment point passes through the detector 37 twice, causing the detector 37 to emit two signals. The time difference between the two signals emitted by the detector 37 can be used to determine the time required for the paper roll 11 to rotate one circle.

[0243] Because the rotational speed and circumference of the active roller 34 are constant, the number of rotations of the active roller 34 can be calculated based on the time required for the paper roll 11 to rotate one circle. The circumference of the paper roll 11 can be calculated based on the number of rotations of the active roller 34 and its circumference, and thus the height of the axis of the paper roll 11 can be obtained.

[0244] Furthermore: when the traveling system 2 is an RGV rail vehicle, the position of the paper roll 11 on the traveling system 2 is fixed. After the height of the axis of the paper roll 11 changes, the axis of the paper roll 11 does not coincide with the motion trajectory of the clamping head 131. Therefore, it is necessary to move the paper roll 11 so that its axis coincides with the motion trajectory of the clamping head 131.

[0245] When the traveling system 2 is an AVG intelligent vehicle, the paper roll 11 can move synchronously with the traveling system 2 so that the axis of the paper roll 11 can fall on the motion trajectory of the clamping head 131. However, an angle may be formed between the axis of the paper roll 11 and the motion trajectory of the clamping head 131, and it is difficult for the AVG intelligent vehicle to make precise turns in a small range. Therefore, it is necessary to rotate the paper roll 11 so that its axis coincides with the motion trajectory of the clamping head 131.

[0246] In order to solve the above technical problems.

[0247] The paper roll transfer device 3 includes a second driver 38, which is connected to the adaptive slide 31 and the paper roll supporting platform 33. The second driver 38 is communicatively connected to the controller and is used to drive the paper roll supporting platform 33 to move so that the paper roll 11 is aligned with the paper roll support 13.

[0248] Optionally: the second drive 38 includes a servo slide and / or a servo turntable;

[0249] The servo slide is connected to the adaptive slide 31 and the paper roll carrier 33, and is used to drive the paper roll carrier 33 to move a specified distance along a second direction, where the second direction is horizontal and perpendicular to the first direction;

[0250] The servo turntable is connected to the adaptive slide 31 and the paper roll supporting platform 33 and is used to drive the paper roll supporting platform 33 to rotate around a vertical axis at a specified angle.

[0251] The specific structures of the paper roll supporting platform 33 and the second driver 38 should be selected according to actual needs.

[0252] When the traveling system 2 is an RGV rail vehicle, the relative distance between the traveling system 2 and the automatic paper splicer 1 is fixed. As long as the track 14 is parallel to the axis of the clamping head 131 , the axis of the paper roll 11 on the traveling system 2 must be parallel to the axis of the clamping head 131 .

[0253] Different paper rolls 11 have different diameters, so the axes of different paper rolls 11 are located at different heights. However, as long as the second driver 38 drives the paper roll support platform 33 to move horizontally, the axis of the paper core 12 must be able to intersect with the axis of the clamping head 131 in a straight line.

[0254] Therefore, when the traveling system 2 is an RGV rail vehicle, the second drive 38 is a servo slide.

[0255] When the walking system 2 is an AVG intelligent vehicle, the relative distance between the walking system 2 and the automatic paper splicer 1 can be adjusted automatically by the walking system 2. At this time, the possible problem is that there is an angle between the axis of the paper roll 11 and the axis of the clamping head 131. However, as long as the second driver 38 drives the paper roll supporting platform 33 to rotate around the vertical axis, the axis of the paper core 12 must be able to intersect with the axis of the clamping head 131 in a line.

[0256] Therefore, when the traveling system 2 is an AVG intelligent vehicle, the second drive 38 is a servo turntable.

[0257] When the traveling system 2 is driven by a worker, for example, the traveling system 2 is a forklift, the second driver 38 is a combination of a servo slide and a servo turntable, which eliminates errors caused by manual driving through multiple movements.

[0258] Optionally: the adaptive slide 31 includes: a body 311 slidably connected to a paper roll carrying platform 33 ;

[0259] Wheels 312 are provided on the circumference of the vehicle body 311 and abut against the bearing surface of the traveling system 2;

[0260] The guide rod 313 horizontally passes through the vehicle body 311 and is connected to the bearing surface of the traveling system 2 .

[0261] The vehicle body 311 is used to bear the weight of the paper roll bearing platform 33 . The weight of the vehicle body 311 is borne by the wheels 312 . The guide rods 313 are only used to guide the moving direction of the vehicle body 311 . The guide rods 313 themselves are not subjected to any force.

[0262] Optionally: the first driver 32 includes: an elastic member 321 connected to the bearing surface of the walking system 2 and abutting against one side of the vehicle body 311 in the moving direction;

[0263] The damping stopper 322 is connected to the bearing surface of the traveling system 2 and abuts against the other side of the vehicle body 311 in the moving direction.

[0264] The elastic member 321 is a spring mounted on the guide rod 313, and the damping stop 322 is a hydraulic damper. When the paper roll holder 13 clamps the paper roll 11, the paper roll 11 moves along with the clamping head 131, causing the vehicle body 311 to move on the bearing surface of the walking system 2 through the wheels 312, and the elastic member 321 is compressed.

[0265] After the paper roll 11 is lifted by the paper roll support 13 , the elastic member 321 drives the body 311 to return to its original position by its own elastic force, so that the body 311 hits the damping stopper 322 and stops moving.

[0266] Optionally, the paper roll transfer device 3 includes a weighing device (not shown in the figure), which is used to weigh the weight of the paper roll 11 placed on the paper roll supporting platform 33 .

[0267] The weighing device is a combination of multiple tension and pressure sensors, which can be installed between the walking system 2 and the load-bearing surface of the walking system 2, or between the adaptive slide 31 and the walking system 2, or between the adaptive slide 31 and the paper roll supporting platform 33. The weighing device obtains the weight of the paper roll 11 through the change in the pressure on the paper roll supporting platform 33.

[0268] The weigher sends a signal to the controller so that the controller can determine whether there is a paper roll 11 on the paper roll supporting platform 33 .

[0269] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the embodiments of the present invention.
