Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The facing papers on the front and back of the gypsum board are in a wound state before being used to hold the gypsum slurry. It usually includes a paper roll 11 and a paper core 12 in its axis. The paper core 12 is in the shape of a hollow cylinder.

[0034] In an existing paper core removal device of an automatic paper splicing machine, the structures related to the upper paper and the lower paper include paper roll brackets 13. There are usually 2 paper roll brackets 13, one of which is spare. When the paper roll 11 on one paper roll bracket 13 is in use, the paper roll 11 on the other paper roll bracket 13 is in a spare state. When the spare paper roll 11 is enabled, only the paper core 12 remains on the original paper roll bracket 13, and it needs to be removed and a new paper roll 11 needs to be replaced.

[0035] Generally, the paper roll bracket 13 includes 2 clamping heads 131 and 2 force arms 132. The 2 force arms 132 can swing around one end thereof. The 2 clamping heads 131 are respectively installed at the free ends of the 2 force arms 132. One of the clamping heads 131 has a motor, and the other clamping head 131 has a disc brake.

[0036] The 2 force arms 132 can perform a swinging motion around a horizontal axis under the action of a hydraulic system or a motor, and perform a linear motion along the horizontal line under the action of the hydraulic system or the motor to realize the actions of driving the clamping heads 131 to rise, fall, approach each other and move away from each other, so that the 2 clamping heads 131 can be inserted into the inside 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 for rotation.

[0037] Figure 1A mechanical schematic diagram showing the process of manually replacing the paper roll 11 is presented. A track 14 is provided below the paper roll bracket 13, and a track trolley 15 is installed on the track 14. The paper roll 11 is usually placed beside the track 14.

[0038] 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 track trolley 15, and the paper core 12 is directly taken away by the staff.

[0039] The paper roll 11 is pushed by the staff onto the track trolley 15, and then the track trolley 15 is moved through the track 14 so that the track trolley 15 and the paper roll 11 are moved between the two clamping heads 131.

[0040] Since the paper core 12 is very light, removing the paper core 12 is not a burden for the staff. However, a staff member usually operates multiple automatic paper splicing machines, and sometimes it is difficult to timely remove the paper core 12. When designing a device for automatically supplying the paper roll 11 to the automatic paper splicing machine, the remaining paper core 12 on the automatic paper splicing machine will interfere with the automatic feeding of the paper roll 11.

[0041] As Figures 2 - 5 shown, an embodiment of a paper core removal device for an automatic paper splicing machine is provided to solve the above technical problems.

[0042] Its main structure includes a traveling system 2 and a paper core transfer device 6.

[0043] The traveling system 2 bears weight and travels on the ground. The traveling system 2 can be an RGV rail vehicle or an AVG intelligent vehicle;

[0044] The paper core transfer device 6 moves on the ground through the traveling system 2. The paper core transfer device 6 is used to carry the paper core 12 and cooperate with the action of the automatic paper splicing machine 1 to complete the action of removing the paper core 12 from the clamping head 131;

[0045] Among them, the paper core transfer device 6 includes a storage box 61, a stripping member 63, a driver 64, a guiding module 65, and a reset module 66.

[0046] The storage box 61 is placed on the bearing surface of the traveling system 2, and an opening 611 is formed on the top surface of the storage box 61;

[0047] The stripping member 63 is movably connected to the storage box 61. The stripping member 63 has degrees of freedom of moving 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 stroke of the stripping member 63 moving along the first direction satisfies the following conditions:

[0048] 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 2 times the axial length of the clamping head 131;

[0049] The driver 64 connects the stripping member 63 and the storage box 61. The driver 64 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;

[0050] The guiding module 65 contacts the moving clamping head 131 among the two clamping heads 131 and moves along with the movement of the clamping head 131. The guiding module 65 is elastically connected to the stripping member 63 so that the stripping member 63 moves to the end of the stroke along the first direction;

[0051] The reset module 66 connects the stripping member 63 and the guiding module 65. The reset module 66 is used to enable the stripping member 63 and the guiding module 65 to return to their original positions after moving and losing the external force.

[0052] As previously described, when the staff removes the paper core 12 from the paper roll bracket 13, one of the two force arms 132 moves away from the other, so that the two clamping heads 131 move away from each other. At this time, one end of the paper core 12 is separated from one clamping head 131, and the other end of the paper core 12 is still inserted into one clamping head 131.

[0053] The stripping member 63 can adopt a mechanical claw, and the function of the stripping member 63 is to clamp the paper core 12.

[0054] The stripping member 63 can move along the first direction through a cylinder. However, this requires the cylinder to move synchronously with the clamping head 131 at the same time and at the same speed, which is relatively difficult to achieve.

[0055] However, by using the guiding module 65 to drag the stripping member 63 through the reset module 66, and at the same time the guiding module 65 moves along with one clamping head 131, the stripping member 63 can easily move synchronously with the clamping head 131 at the same time and at the same speed.

[0056] The paper core 12 moves synchronously with the stripping member 63 so that one end of the paper core 12 is separated from the stationary clamping head 131. Then the stripping member 63 moves to the end of the stroke and stops moving. The moving clamping head 131 continues to move and is separated 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 member 63 releases the paper core 12 and makes it fall into the interior of the storage box 61.

[0057] After the clamping head 131 is reset, the stripping member 63 and the guiding module 65 are reset under the resilience of the reset module 66, and the distance between the stripping member 63 and the guiding module 65 is restored.

[0058] Furthermore:

[0059] When the spare paper roll 11 is enabled, not only the paper core 12 remains from the previously used paper roll 11, but also about 2 meters of paper remains. This part of the paper also needs to enter the interior of the storage box 61, otherwise it will affect the operation of the automatic paper splicing machine 1.

[0060] In order to guide the paper core 12 and the remaining paper peeled off by the stripping member 63 to fall into the interior of the storage box 61 through the opening 611, the following provides an optional embodiment, and its specific structure is described as follows.

[0061] One side of the opening 611 is located on the side of the storage box 61 away from the automatic paper splicing machine 1, and the other side of the opening 611 is located in the middle of the storage box 61 and a discharge plate 62 is formed. The discharge plate 62 extends upward and in the direction close to the automatic paper splicing machine 1. When the clamping head 131 of the automatic paper splicing machine 1 descends, the bottom of the paper core 12 on the paper roll bracket 13 can be lapped on the top surface of the discharge plate 62.

[0062] During the process that the paper core 12 rolls along the discharge plate 62 into the interior of the storage box 61, the paper core 12 drags the remaining paper on its surface and enters the interior of the storage box 61 together.

[0063] Furthermore:

[0064] If there is a relatively long piece of paper remaining on the paper core 12, such as about 3 meters of paper, then about 1 meter of paper will still be lapped on the edge of the opening 611 and remain outside the storage box 61. To solve this problem.

[0065] The bottom wall 612 inside the storage box 61 slopes downward and in the direction close to the automatic paper splicing machine 1.

[0066] The paper core 12 rolls along the discharge plate 62 in the direction away from the automatic paper splicing machine 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 splicing machine 1 to extend the moving distance of the process of discharging the paper core 12, so that the relatively long paper remaining on the paper core 12 can also completely enter the interior of the storage box 61.

[0067] Optionally:

[0068] To facilitate the staff to take out the paper cores 12 collected inside the storage box 61.

[0069] A movable door 613 is provided at the lowest part of the side of the storage box 61 close to its bottom wall.

[0070] The top of the movable door 613 is rotatably connected to the storage box 61 through a pin shaft, and the side of the movable door 613 is fixedly connected to the storage box 61 through a bolt. Pulling out the bolt allows the movable door 613 to be opened through the handle to take out the paper core 12 inside the storage box 61.

[0071] On the other hand:

[0072] This specific embodiment also provides a stripping member 63 different from the clamping jaws, which can not only achieve the purpose of frictionally connecting with the paper core 12, but also guide the paper core 12 to move along the unloading plate 62.

[0073] The paper core transfer device 6 further includes a first sliding column 67, the first sliding column 67 is fixedly connected to the storage box 61, the axis of the first sliding column 67 is parallel to the first direction, and the stripping member 63 is connected to the first sliding column 67 through a cylindrical pair;

[0074] The top surface of the unloading plate 62 is a smooth surface, the stripping member 63 is a claw-shaped plate member, the bottom surface of the stripping member 63 is a rough surface, and when the stripping member 63 rotates along the second direction, it can press the paper core 12 lapped on the top surface of the unloading plate 62, so that the stripping member 63 is frictionally connected to the paper core 12, and the unloading plate 62 and the paper core 12 slip relative to each other.

[0075] The stripping member 63 can move along the axis of the first sliding column 67 or rotate around the axis of the first sliding column 67.

[0076] To facilitate the relative movement between the unloading plate 62 and the paper core 12, the unloading plate 62 can also be replaced with a roller table or a universal ball table.

[0077] The driver 64 can be a cylinder. The body of the driver 64 is connected to the storage box 61 through a cylindrical pair, and the actuator of the driver 64 is connected to the stripping member 63 through a cylindrical pair. The movement of the stripping member 63 along the axial direction of the first sliding column 67 has no influence on the position of the driver 64.

[0078] When both ends of the paper core 12 are separated from the clamping head 131, the pressure transmitted by the driver 64 to the stripping member 63 causes the stripping member 63 to continue to rotate downward, thereby pushing the paper core 12 to move along the unloading plate 62 into the storage box 61.

[0079] Furthermore:

[0080] Since the unloading plate 62 must be misaligned with the stripping member 63 so that the stripping member 63 can push the paper core 12 to continue to fall over the unloading plate 62, because the two force application points of the paper core 12 are not in the same position, the paper core 12 is easily pushed and flipped by the stripping member 63, making it difficult for the paper core 12 to enter the storage box 61 through the opening 611.

[0081] To solve this problem, the following provides an alternative embodiment, and its specific structure is described as follows.

[0082] When the stripping member 63 moves along the second direction, it does not contact the storage box 61 and the unloading plate 62. There are 2 unloading plates 62, and the stripping member 63 is located between the 2 unloading plates 62. When the stripping member 63 moves to the maximum stroke along the second direction, the paper core 12 on the unloading plate 62 is pushed by the stripping member 63 into the interior of the storage box 61.

[0083] The 2 unloading plates 62 are used to prevent the paper core 12 from flipping.

[0084] Optionally:

[0085] The reset module 66 includes a first elastic member 661, and the first elastic member 661 is located on the side of the stripping member 63 close to the movable clamping head 131;

[0086] A first stop ring 671 and a second stop ring 672 are formed on the first sliding column 67. The first stop ring 671 and the second stop ring 672 are respectively located on both sides of the stripping member 63. Among them, the first stop ring 671 is close to the movable clamping head 131. The first elastic member 661 is sleeved on the first sliding column 67, and both ends of the first elastic member 661 abut against the stripping member 63 and the first stop ring 671.

[0087] Specifically:

[0088] The first elastic member 661 is a spring, and the first elastic member 661 is used to drive the stripping member 63 to reset.

[0089] The first stop ring 671 and the second stop ring 672 are also used to limit the stroke of the stripping member 63 in the first direction. When the stripping member 63 contacts the second stop ring 672, the stripping member 63 is at the starting point of its own stroke. When the first elastic member 661 is compressed to the limit, the stripping member 63 is at the end point of its own stroke.

[0090] Furthermore:

[0091] Since the stripping member 63 has 2 degrees of freedom at the same time, in order to always elastically connect the stripping member 63 and the guiding module 65, the guiding module 65 also has to have 2 degrees of freedom, that is, the guiding module 65 can also move along the first direction and the second direction. For this reason, the following provides an alternative embodiment of the guiding module 65, and its specific structure is described as follows.

[0092] The guiding module 65 includes a guiding block 651 which is in a long strip shape. One end of the guiding block 651 is connected to the first sliding column 67 through a cylindrical pair. The guiding block 651 is in transmission connection with the execution part of the driver 64 and rotates synchronously with the stripping part 63. When the stripping part 63 rotates along the second direction and presses on the paper core 12, the free end of the guiding block 651 is coaxial with the axis of the paper core 12.

[0093] When the unloading plate 62 and the stripping part 63 clamp the paper core 12, the free end of the guiding block 651 is coaxial with the axis of the paper core 12. That is, when the clamping head 131 moves, the side of the clamping head 131 away from the paper core 12 can contact the guiding block 651 and push the guiding block 651 to move.

[0094] A rubber pad 652 is installed on the side of the guiding 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 guiding block 651.

[0095] Optionally:

[0096] The middle end of the stripping part 63 is slidably connected to the guiding block 651 through a second sliding column 68. The second sliding column 68 is parallel to the first sliding column 67. The execution part of the driver 64 is connected to the second sliding column 68 through a cylindrical pair.

[0097] The driver 64 drives the stripping part 63 and the guiding block 651 to move synchronously through the second sliding column 68.

[0098] Optionally:

[0099] The guiding block 651 and the stripping part 63 are elastically connected through the following structure.

[0100] The reset module 66 includes a second elastic member 662 which is located on the side of the stripping part 63 away from the movable clamping head 131;

[0101] A third stop ring 681 and a fourth stop ring 682 are formed on the second sliding column 68. The third stop ring 681 and the fourth stop ring 682 are respectively located on both sides of the stripping part 63. Among them, the third stop ring 681 is close to the movable clamping head 131. The second elastic member 662 is sleeved on the second sliding column 68, and both ends of the second elastic member 662 abut against the stripping part 63 and the fourth stop ring 682.

[0102] Specifically, the second elastic member 662 is a spring. The second elastic member 662 is used to elastically connect the stripping part 63 and the guiding module 65 so that the stripping part 63 can move along with the guiding module 65.

[0103] After the paper core 12 enters the inside of the storage box 61, the second elastic member 662 also drives the guiding module 65 to reset through the resilience until the stripping member 63 contacts the third stop ring 681.

[0104] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the embodiments of the present invention.
