DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] The face paper and back paper of the gypsum board are in a rolled state before being used to clamp the gypsum slurry, which usually includes a paper roll 11 and a paper core 12 in the axis of the paper roll 11, and the paper core 12 is in a hollow cylindrical shape.

[0033] The structure related to paper feeding and paper discharging in the existing automatic paper receiving machine 1 includes a paper roll support 13, which usually has two, one of which is a spare, when the paper roll 11 on one paper roll support 13 is used, the paper roll 11 on the other paper roll support 13 is in a standby state, when the standby paper roll 11 is used, the paper roll 11 on the original paper roll support 13 is only left with the paper core 12, which needs to be removed and replaced with a new paper roll 11.

[0034] Usually, the paper roll support 13 includes two clamping heads 131 and two force arms 132, the two force arms 132 can swing around one end, and 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.

[0035] Two force arms 132 can perform swing movement around a horizontal axis under the action of a hydraulic system or an electric motor, and perform linear movement along a horizontal line under the action of a hydraulic system or an electric motor, to realize the actions of driving the clamping heads 131 to ascend, descend, approach each other and move away from each other, so that the two 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 hung in the air to rotate.

[0036] Figure 1 A mechanical diagram showing the process of manually replacing the paper roll 11 is shown. An orbit 14 is arranged below the paper roll support 13, and an orbit trolley 15 is installed on the orbit 14. The paper roll 11 is usually placed beside the orbit 14.

[0037] The two clamping heads 131 have been previously moved away from each other and lifted to avoid the moving path of the orbit trolley 15. The paper core 12 is directly taken away by the worker.

[0038] The paper roll 11 is pushed onto the orbit trolley 15 by the worker, and then the orbit trolley 15 is moved through the orbit 14, so that the orbit trolley 15 and the paper roll 11 move between the two clamping heads 131.

[0039] Figure 2 (a) ~ Figure 2 (f) shows an action diagram of the above-mentioned steps of replacing the paper roll 11, in which:

[0040] As Figure 2 (a) shows that the two paper rolls 11 on the automatic paper receiving machine 1 are in a state that does not need to be replaced;

[0041] As Figure 2 (b) shows that one of the paper rolls 11 on the automatic paper receiving machine 1 is about to be used up;

[0042] As Figure 2 (c) shows that the two clamping heads 131 are moved away from each other, and the worker takes out one of the paper cores 12 on the automatic paper receiving machine 1;

[0043] As Figure 2 (d) shows that the worker pushes a new paper roll 11 between the two clamping heads 131;

[0044] As Figure 2 (e) shows that the two clamping heads 131 approach each other and clamp the new paper roll 11 for use;

[0045] As Figure 2 (f) shows that another paper roll 11 has been used up and needs to be replaced, and at this time the new paper roll 11 has been put into use.

[0046] Since the weight of the paper roll 11 is large, usually about 2 tons, the process of replacing the paper roll 11 is labor-intensive, and usually requires two people to perform the operation of replacing the paper roll 11, one of whom pushes the paper roll 11 to maintain its position, and the other manipulates the automatic paper receiving machine 1 to use the clamping head 131 to clamp the paper roll 11, which is high in labor cost.

[0047] To solve the above technical problems, as shown in the specific embodiment, the paper roll automatic feeding vehicle is provided to solve the above technical problems. Figures 3-6

[0048] The main structure includes a walking system 2 and a paper roll moving device 3.

[0049] The walking system 2 is used to carry the weight and walk on the ground, and the walking system 2 can be an RGV track car or an AVG intelligent car.

[0050] The paper roll moving device 3 moves on the ground through the walking system 2, and the paper roll moving device 3 is used to carry the paper roll 11 and cooperate with the action of the paper roll support 13 to complete the feeding action.

[0051] As shown in the specific embodiment, the paper roll moving device 3 includes an adaptive sliding table 31 arranged on the walking system 2 and capable of moving along a first direction, which is horizontal. Figure 3

[0052] A first driver 32 is connected between the adaptive sliding table 31 and the walking system 2, and the first driver 32 is used to drive the adaptive sliding table 31 back to the original position when the position of the adaptive sliding table 31 changes.

[0053] A paper roll carrying table 33 is arranged on the adaptive sliding table 31, and the paper roll carrying table 33 is used to carry the paper roll 11. When the paper roll 11 is placed on the paper roll carrying table 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 trail of the execution part of the paper roll support 13 is located is parallel to the axis of the paper roll 11.

[0054] As shown in the specific embodiment, the walking system 2 is used to drive the paper roll moving device 3 to move to the side of the automatic paper receiving machine 1, and the paper core 12 is substantially located between the two clamping heads 131. Figure 4 5 The execution part of the paper roll support 13 is the clamping head 131 and the force arm 132, and the clamping head 131 can also be regarded as the execution end of the paper roll support 13.

[0055] The execution part of the paper roll support 13 is the clamping head 131 and the force arm 132, and the clamping head 131 can also be regarded as the execution end of the paper roll support 13.

[0056] ​​​The clamping head 131 performs circumferential movement 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 curved surface of the sector, and 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, and when the clamping head 131 and the axis of the paper roll 11 are located on the intersection line, the clamping head 131 can be inserted into the inside of the paper core 12.

[0057] Since only one of the two force arms 132 performs linear movement under the action of the hydraulic system in the existing paper roll 11, during the process that the two clamping heads 131 are inserted into the paper core 12 and clamp the paper roll 11, the paper roll 11 will be pushed by the clamping head 131 to move along the axis direction of the paper roll 11, at this time, the self-adaptive sliding table 31 moves on the walking system 2, and the self-adaptive sliding table 31, the paper roll bearing table 33 and the paper roll 11 remain relatively stationary.

[0058] 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, lifts the paper roll 11, so that the paper roll 11 is separated from the paper roll bearing table 33, the self-adaptive sliding table 31 returns to the original position under the action of the first driver 32, the walking system 2 moves the paper roll transfer device 3 away, and the feeding work is completed.

[0059] Further:

[0060] In order to automatically achieve the result that the axis of the clamping head 131 is aligned with the axis of the paper core 12 in the above working steps, a controller capable of linkage control of the automatic paper receiving machine 1, the walking system 2 and the paper roll transfer device 3 is also needed, so that the paper automatic feeding vehicle can automatically perform the feeding action without manual operation.

[0061] Therefore, an optional embodiment is provided, and the specific structure is as follows.

[0062] A code disc (not shown in the figure) is installed on the rotating shaft of the paper roll support 13, and the code disc is used to read the rotating angle of the rotating shaft.

[0063] Specifically, the hydraulic system for controlling the swing of the force arm 132 in the paper roll support 13 is in communication connection with the controller, the controller reads the swing angle of the paper roll support 13 through the code disc, and sends a stop signal to the paper roll support 13 when the force arm 132 swings to a specified angle, so that the force arm 132 stops at the specified angle, and further so that the clamping head 131 stops at the specified height.

[0064] The paper roll support 13 stops swinging at the following two angles:

[0065] I. The angle at which the clamping head 131 rises to the highest height to avoid the walking system 2.

[0066] II. The angle at which the clamping head 131 is aligned with the axis of the paper core 12, so that the clamping head 131 can be inserted into the paper core 12.

[0067] The diameters of the paper rolls 11 of the same specification are the same, and the height of the axis of the paper roll 11 is fixed when the paper roll 11 is placed on the paper roll loading platform 33. Therefore, the diameters of the paper rolls 11 of different specifications can be input into the controller in advance, and the controller can calculate the height of the axis of the paper roll 11.

[0068] Subsequently, the controller calculates the angle at which the paper roll support 13 needs to be swung so that the clamping head 131 is aligned with the axis of the paper roll 11 according to the height of the axis of the paper roll 11, and then establishes a table of the specifications of the paper rolls 11 and the swinging angles of the paper roll support 13. Subsequently, the controller can obtain the angle at which the paper roll support 13 needs to be swung when clamping paper rolls 11 of different specifications by looking up the table.

[0069] Further, the controller can obtain the diameter of the paper roll 11 by the following methods.

[0070] When the specification of the paper roll 11 is changed, the diameter of the paper roll 11 changes, and the height of the axis of the paper roll 11 also changes accordingly. At this time, the rotation angle of the force arm 132 and / or the linear movement distance of the paper roll loading platform 33 in the horizontal direction need to be adjusted so that the axis of the paper roll 11 can still be aligned with the axis of the clamping head 131 when the diameter of the paper roll 11 is changed. For this purpose, the diameter of the paper roll 11 needs to be obtained, and then the rotation angle of the force arm 132 needs to be modified.

[0071] The following provides several optional embodiments for obtaining the diameter of the paper roll 11.

[0072] Optionally, the controller can obtain the diameter of the paper roll 11 by the following methods.

[0073] The paper roll moving device 3 comprises:

[0074] A visual detection device (not shown in the figure) is arranged on the walking system 2 and faces the paper roll loading platform 33. The visual detection device is used to obtain an image above the paper roll loading platform 33 from the first direction.

[0075] The visual detection device comprises a CCD camera and an image processor. The CCD camera obtains an end surface image of the paper roll 11 on the paper roll loading platform 33 from an axial perspective, and then the image processor obtains the diameter of the paper roll 11.

[0076] However, the CCD camera is greatly affected by the light environment and vibration, and is easily damaged in a collision. Therefore, the CCD camera is not suitable for being installed on the walking system 2 which moves around.

[0077] As another optional embodiment of the above embodiment:

[0078] The paper roll transfer device 3 comprises:

[0079] a driving roller 34 disposed on the paper roll support platform 33 and capable of driving rotation, an axis of the driving roller 34 being parallel to the first direction;

[0080] a driven roller 35 disposed on the paper roll support platform 33 and capable of driven rotation, an axis of the driven roller 35 being parallel to the axis of the driving roller 34;

[0081] a distance measuring device disposed on the paper roll support platform 33 and located between the driving roller 34 and the driven roller 35, the distance measuring device being used to measure a distance between an outer circumferential surface of the paper roll 11 and itself placed on the driving roller 34 and the driven roller 35.

[0082] The distance measuring device is not shown in the figure, and can be a laser distance measuring sensor.

[0083] The driving roller 34 and the driven roller 35 are used to drive the paper roll 11 to rotate one round, so that the distance measuring device can obtain the distance between each part of the paper roll 11 and itself, to obtain an average value, thereby eliminating the roundness error of the paper roll 11.

[0084] Since the distance between the driving roller 34 and the driven roller 35 is fixed, the distance between the outer circumferential surface of the paper roll 11 and the distance measuring device is measured, and the distance between the driving roller 34 and the driven roller 35 is combined, so as to calculate the arc of the outer circumferential surface of the paper roll 11, and further calculate the diameter of the paper roll 11 and the height of the axis thereof.

[0085] However, when the specification of the paper roll 11 changes greatly, so that the diameter of the paper roll 11 changes greatly, the distance between the driving roller 34 and the driven roller 35 should be adjusted, so that the driving roller 34 and the driven roller 35 can always better support the paper roll 11, at this time, the distance measuring device will no longer be applicable.

[0086] As shown in FIG. 2, as another alternative embodiment of the above embodiment: Figure 6

[0087] The paper roll transfer device 3 comprises:

[0088] a driving roller 34 disposed on the paper roll support platform 33 and capable of driving rotation, an axis of the driving roller 34 being parallel to the first direction;

[0089] a driven roller 35 disposed on the paper roll support platform 33 and capable of driven rotation, an axis of the driven roller 35 being parallel to the axis of the driving roller 34;

[0090] an ink jet device 36 disposed on the paper roll support platform 33 and located between the driving roller 34 and the driven roller 35, the ink jet device 36 being used to spray a point of pigment to the outer circumferential surface of the paper roll 11;

[0091] ​A detector 37 is arranged beside the ink jet 36, the detector 37 is used to sense the pigment point ejected by the ink jet 36 and send a signal.

[0092] The pigment ejected by the ink jet 36 can gradually disappear over time, or fade in high temperature when the gypsum board is dried, so that the pigment ejected by the ink jet 36 has no effect on the surface quality of the gypsum board.

[0093] The detector 37 can be a color sensor or a CCD camera, the detector 37 is communicatively connected to the controller, the pigment point passes through the detector 37 twice during the rotation of the paper roll 11, so that the detector 37 sends two signals, and the time difference between the two signals sent by the detector 37 can obtain the time required for the paper roll 11 to rotate one revolution.

[0094] Because the rotation speed and the circumference of the driving roller 34 are constant, the number of rotations of the driving roller 34 can be calculated by the time required for the paper roll 11 to rotate one revolution, and the circumference of the paper roll 11 can be calculated according to the number of rotations of the driving roller 34 and the circumference of the driving roller 34, and then the height of the axis of the paper roll 11 can be obtained.

[0095] Further:

[0096] The automatic paper receiving machine is provided with a CCD camera, which is used to detect the distance and angle between the axis of the paper roll 11 and the clamping head 131.

[0097] When the walking system 2 is an RGV rail car, the position of the paper roll 11 on the walking system 2 is fixed, and 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, so the paper roll 11 needs to be moved to coincide with the motion trajectory of the clamping head 131.

[0098] When the walking system 2 is an AVG intelligent car, the paper roll 11 can move synchronously with the walking system 2, so that the axis of the paper roll 11 can fall on the motion trajectory of the clamping head 131, but the axis of the paper roll 11 may form an angle with the motion trajectory of the clamping head 131, and the AVG intelligent car is difficult to accurately turn in a small range, so the paper roll 11 needs to be rotated to coincide with the motion trajectory of the clamping head 131.

[0099] In order to solve the above technical problems.

[0100] The paper roll moving device 3 comprises a second driver 38, the second driver 38 is connected to the adaptive sliding table 31 and the paper roll supporting table 33, the second driver 38 is communicatively connected to the controller, and the second driver 38 is used to drive the paper roll supporting table 33 to move so that the paper roll 11 is aligned with the paper roll support 13.

[0101] Optionally:

[0102] The second driver 38 comprises a servo slide and / or a servo turret;

[0103] The servo slide connects the adaptive slide 31 and the paper roll carrier 33, and is used to drive the paper roll carrier 33 to move a specified stroke along a second direction, which is horizontal and perpendicular to the first direction;

[0104] The servo turret connects the adaptive slide 31 and the paper roll carrier 33, and is used to drive the paper roll carrier 33 to rotate a specified angle around a vertical axis.

[0105] The specific structure of the paper roll carrier 33 and the second driver 38 should be selected according to actual needs.

[0106] When the walking system 2 is an RGV rail car, the relative distance between the walking system 2 and the automatic paper receiving machine 1 is fixed, and as long as the rail 14 is parallel to the axis of the clamping head 131, the axis of the paper roll 11 on the walking system 2 will necessarily be parallel to the axis of the clamping head 131.

[0107] Different paper rolls 11 have different diameters, so the axes of different paper rolls 11 are at different heights, but as long as the second driver 38 drives the paper roll carrier 33 to move along the horizontal direction, the axis of the paper core 12 will necessarily intersect with the axis of the clamping head 131.

[0108] Therefore, when the walking system 2 is an RGV rail car, the second driver 38 is a servo slide.

[0109] When the walking system 2 is an AVG intelligent car, the relative distance between the walking system 2 and the automatic paper receiving machine 1 can be automatically adjusted by the walking of the walking system 2, at this time, the problem that may exist is that the axis of the paper roll 11 has an angle with the axis of the clamping head 131, but as long as the second driver 38 drives the paper roll carrier 33 to rotate around a vertical axis, the axis of the paper core 12 will necessarily intersect with the axis of the clamping head 131.

[0110] Therefore, when the walking system 2 is an AVG intelligent car, the second driver 38 is a servo turret.

[0111] When the walking system 2 is driven by a worker, for example, the walking system 2 is a forklift, the second driver 38 is a combination of a servo slide and a servo turret, which eliminates the error of manual driving through multiple movements.

[0112] Optionally, as shown in Figure 3 and Figure 4 , the adaptive slide 31 comprises:

[0113] The adaptive slide 31 comprises:

[0114] The body 311 is connected to the paper roll carrier 33 by sliding connection.

[0115] The wheels 312 are arranged on the periphery of the body 311 and abut against the load bearing surface of the walking system 2.

[0116] The guide rod 313 horizontally penetrates the body 311 and is connected to the load bearing surface of the walking system 2.

[0117] The body 311 is used to bear the weight of the paper roll carrier 33, the weight of the body 311 is borne by the wheels 312, and the guide rod 313 is only used to guide the moving direction of the body 311, and the guide rod 313 itself is not stressed.

[0118] Optionally, as shown in Figure 3 and Figure 4 :

[0119] The first driver 32 comprises:

[0120] The elastic member 321 is connected to the load bearing surface of the walking system 2 and abuts against one side of the moving direction of the body 311;

[0121] The damping stopper 322 is connected to the load bearing surface of the walking system 2 and abuts against the other side of the moving direction of the body 311.

[0122] The elastic member 321 is a spring sleeved on the guide rod 313, and the damping stopper 322 is a hydraulic damper. During the process that the paper roll support 13 clamps the paper roll 11, the paper roll 11 moves with the clamping head 131, so that the body 311 moves on the load bearing surface of the walking system 2 through the wheels 312, and the elastic member 321 is compressed.

[0123] After the paper roll 11 is lifted by the paper roll support 13, the elastic member 321 drives the body 311 to reset by the elastic force of the elastic member 321, so that the body 311 hits the damping stopper 322 and stops moving.

[0124] Optionally:

[0125] The paper roll moving device 3 comprises 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 carrier 33.
