Description

Technical Field

[0001] The invention relates to the technical field of sheet paper laying processing, and in particular to an automatic paper laying device and a melamine sheet paper laying production line. Background Art

[0002] The full name of melamine board is melamine impregnated film paper veneer artificial board. Melamine board is made by soaking surface paper with different colors or textures in melamine resin adhesive, then drying it to a certain degree of solidification, and laying it on the surface of particleboard, moisture-proof board, medium-density fiberboard, plywood, blockboard, multi-layer board or other hard fiberboard, and then hot pressing it to make a decorative board.

[0003] In the manufacturing process of melamine board, the melamine board and the face paper need to be laid on top of each other, and then the embossing of the substrate and the printed pattern of the paper need to be completely overlapped under the operation of the hot press. Such equipment can refer to a hot press disclosed in Chinese patent announcement number CN210705200U, which hot presses the melamine board and the face paper into shape through an upper mold and a lower mold.

[0004] In some products, both sides of the melamine board are covered with a layer of paper, and the upper surface of the paper has a pattern, and the lower surface is used for laminating. The paper is usually stacked on the operating table with the pattern facing upward. Therefore, when laying paper, it is necessary to first turn the paper 180 degrees, place it in the laying area, and then put the melamine board on it, and then lay the other paper on the upper surface of the melamine board. Usually, a paper laying device is used for double-sided paper laying, such as a separation, transfer and flipping device for melamine board facing paper disclosed in Chinese patent announcement number CN 220617687U, which includes a frame, a left-right motion mechanism, an up-and-down motion mechanism and a clamp; the left-and-right motion mechanism is arranged on the frame; the up-and-down motion mechanism is arranged on the left-and-right motion mechanism, and the left-and-right motion mechanism drives the up-and-down motion mechanism to reciprocate in the left-and-right direction; the clamp is arranged on the up-and-down motion mechanism, and the up-and-down motion mechanism drives the clamp to reciprocate in the up-and-down direction, and the clamp is used to absorb the facing paper.

[0005] In the actual processing process, due to the different placement positions, inclination angles and placement angles of the melamine board, if the facial paper is directly laid in the same flat laying action, the facial paper is prone to misalignment. The paper laying device in the prior art does not have the function of adjusting the placement position, inclination angle and placement angle of the facial paper, and cannot solve the problem of poor paper laying alignment.

[0006] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0007] In view of the above-mentioned deficiencies of the prior art, an object of the present invention is to provide an automatic paper laying device and a melamine board paper laying production line to solve the problem of poor paper laying alignment of the prior art paper laying device.

[0045] Please refer to Figures 1 to 13 This embodiment discloses a melamine board paper laying production line, including an automatic paper laying device, a frame 80, a processing table 91 and a storage table 93.

[0046] The frame 80 includes a fourth guide rail 81 arranged along the x-direction, a pulley 82 arranged on the sliding frame 10 and slidingly matched with the fourth guide rail 81, and a seventh driving device 83 arranged on the fourth guide rail 81 and used to drive the sliding frame 10 along the x-direction.

[0047] The processing table 91 is arranged below the fourth guide rail 81 and is used as a carrier for laying the surface paper 94 on both end surfaces of the melamine board 92;

[0048] The storage table 93 is disposed on any side of the processing table 91 along the x-direction and is used for stacking and placing tissue paper 94 .

[0049] The automatic paper laying device includes:

[0050] A sliding frame 10, the sliding frame 10 can move along the x direction;

[0051] The lifting mechanism 20 is arranged on the sliding frame 10 along the z direction;

[0052] The tilt adjustment mechanism 30 includes a first bracket 31 connected to the output end of the lifting mechanism 20, a second bracket 32 ​​hinged to one end of the first bracket 31 along the y direction, and a first driving device 33 provided on the first bracket 31 and used for driving the swing end of the second bracket 32 ​​along the z direction;

[0053] The position adjustment mechanism 40 includes a second driving device 41 disposed on the second bracket 32 ​​along the y direction, and a third bracket 42 driven by the second driving device 41;

[0054] The angle adjustment mechanism 50 includes a third driving device 51 disposed at both ends of the third bracket 42 along the y direction and drivable along the x direction, a fourth driving device 52, a first mounting frame 53 driven by the third driving device 51, a second mounting frame 54 driven by the fourth driving device 52, and two rotating shafts 55 connected between the first mounting frame 53 and the second mounting frame 54;

[0055] The clamping mechanism 60 includes a suction cup frame 61 fixed to the two rotating shafts 55 and a plurality of suction cups 62 provided on the suction cup frame 61 .

[0056] In the melamine board paper laying production line of this embodiment, during processing, the face paper 94 is first stacked and placed on the storage table 93, and the seventh driving device 83 is used to drive the sliding frame 10 to move along the x direction, so that the clamping mechanism 60 moves to above the face paper 94, and the lifting mechanism 20 is used to drive the clamping mechanism 60 to descend along the z direction, and the suction cup 62 of the clamping mechanism 60 is used to suck the face paper 94, and then the lifting mechanism 20 is used to raise the height of the face paper 94 along the z direction, and the seventh driving device 83 is used to drive the sliding frame 10 to move along the x direction, so that the face paper 94 is laid on the upper end surface of the melamine board 92 placed on the processing table 91, so that automatic paper laying can be achieved and the processing efficiency is improved.

[0057] It should be noted that the melamine board paper laying production line of this embodiment is also suitable for double-sided stickers of melamine board 92. The operation of double-sided stickers can refer to a melamine board facing paper separation, transfer and flipping device disclosed in Chinese patent announcement No. CN 220617687U, which can be specifically seen in the text content disclosed in paragraph 0041 of its specification and the attached drawings of its specification. Figures 4 to 11 , which will not be elaborated below.

[0058] In addition, in the actual processing, since the surface of the melamine board 92 to be bonded is not parallel to the xy plane, and the facial paper 94 is parallel to the xy plane and stacked on the storage table 93, if the seventh driving device 83, the lifting mechanism 20 and the clamping mechanism 60 directly clamp the facial paper 94 and lay it flat on the surface of the melamine board 92 to be bonded, it is easy to cause the facial paper 94 and the melamine board 92 to be misaligned. Based on this problem, please refer to Figure 7 and Figure 8 The melamine board paper laying production line of this embodiment is further provided with a tilt adjustment mechanism 30, through which the tilt adjustment mechanism 30 can adjust the tilt angle of the surface paper 94 around the x-axis, so as to adapt to various laminating scenarios.

[0059] It should be noted that the tiling mentioned above refers to the action of laying parallel to the xy plane.

[0060] Furthermore, the tilt adjustment mechanism 30 also includes a third mounting frame 34 fixed to one end of the first bracket 31 along the y direction, a first rotating shaft 35 fixed to the third mounting frame 34, a third bearing seat 36 provided on the second bracket 32 ​​and rotatably matched with the first rotating shaft 35, a fourth bearing seat 37 fixed to the other end of the first bracket 31 along the y direction, a second rotating shaft 38 fixed to the first driving device 33 and rotatably matched with the fourth bearing seat 37, a second joint bearing 39 connected to the first driving device 33, and a fifth bearing seat 310 fixed to the second bracket 32 ​​and rotatably matched with the second joint bearing 39. When it is necessary to adjust the tilt angle of the facial paper 94 around the x-axis, the swing end of the second bracket 32 ​​is driven upward or downward by the first driving device 33. Since the rotating end of the second bracket 32 ​​is rotatably connected to the third bearing seat 36 through the first rotating shaft 35, the second bracket 32 ​​can adjust the angle around the first rotating shaft 35, and then drive the clamping mechanism 60 below to adjust the tilt angle of the facial paper 94. The structure is simple, no manual adjustment is required, and the adjustment accuracy is high.

[0061] In addition, since the second bracket 32 ​​rotates around the first rotating shaft 35, in order to enable the first driving device 33 to smoothly drive the swinging end of the second bracket 32, this embodiment sets the fourth bearing seat 37, the second rotating shaft 38, the second joint bearing 39 and the fifth bearing seat 310, so that the first driving device 33 can push the second bracket 32 ​​while also rotating to adjust its posture to avoid the situation where it cannot be pushed.

[0062] Furthermore, the first driving device 33 of the present embodiment adopts an electric cylinder, which is compact and lighter, and no longer requires pumps, oil tanks, and pipelines, etc. It is safer, more environmentally friendly, and has lower noise; the electric cylinder has a fast response speed and can quickly adjust the tilt angle; the electric cylinder has high-precision position control capabilities and can achieve precise linear motion, thereby meeting the requirements of high-precision control of the tilt angle.

[0063] It should be noted that the first driving device 33 of this embodiment adopts an electric cylinder, which is only one of the preferred implementations. In other embodiments, linear driving devices such as air cylinders, hydraulic cylinders, and screw modules can also be used, and are not limited to the electric cylinder of this embodiment.

[0064] For further information, please refer to Figure 5The lifting mechanism 20 includes a fifth driving device 21 arranged on the sliding frame 10 along the z direction, a first joint bearing 22 connected to the output end of the fifth driving device 21, a first bearing seat 23 fixed to the first bracket 31 and rotatably matched with the first joint bearing 22, two second bearing seats 24 fixed to the sliding frame 10, a connecting rod 25 rotatably arranged on the two second bearing seats 24, a gear 26 connected to the two ends of the connecting rod 25 along the y direction, and a rack 27 arranged on the sliding frame 10 along the z direction and meshed with the gear 26. The first bracket 31 is driven by the fifth driving device 21, thereby driving the clamping mechanism 60 to rise and fall along the z direction.

[0065] In addition, in this embodiment, by providing the second bearing seat 24, the connecting rod 25, the gear 26 and the rack 27, when the fifth driving device 21 is driven, the meshing action of the gear 26 and the rack 27 can improve the stability of the movement of the first bracket 31 along the z direction.

[0066] As a preferred implementation, please refer to Figure 4 and Figure 5 The automatic paper laying device of this embodiment further includes a detection and positioning mechanism 70, which includes a first support rod 71 fixed to the first bracket 31, a second support rod 72, a first photoelectric sensor 73 fixed to the first support rod 71, a second photoelectric sensor 74 fixed to the second support rod 72, and a third photoelectric sensor 75. The straight line formed by the positions of the first photoelectric sensor 73 and the second photoelectric sensor 74 is parallel to the y-axis, and the third photoelectric sensor 75 is not on the straight line formed by the positions of the first photoelectric sensor 73 and the second photoelectric sensor 74 or the extension line of the straight line. The first photoelectric sensor 73 and the second photoelectric sensor 74 are used to detect one edge of the tissue paper 94, and then the sensing signal is fed back to the control system, so that the angle of the clamping mechanism 60 is adjusted by the angle adjustment mechanism 50, so that the two rotating shafts 55 are parallel to one edge of the tissue paper 94; the third photoelectric sensor 75 is used to detect the other edge of the tissue paper 94, and then the sensing signal is fed back to the control system, so that the position adjustment mechanism 40 is used to adjust the position of the clamping mechanism 60 along the y-direction, and the detection and positioning by three photoelectric sensors can ensure the subsequent paper laying accuracy of the tissue paper 94.

[0067] In the actual processing, since the position of the melamine board 92 along the y direction may be different from the position of the facial tissue 94 stacked on the storage table 93 along the y direction, if the seventh driving device 83, the lifting mechanism 20 and the clamping mechanism 60 directly clamp the facial tissue 94 and lay it flat on the surface to be bonded of the melamine board 92, it is easy to cause the facial tissue 94 and the melamine board 92 to be misaligned along the y direction. Based on this problem, please refer to Fig. 9 and Fig.10The melamine board paper laying production line of this embodiment is further provided with a position adjustment mechanism 40, through which the position of the surface paper 94 along the y direction can be adjusted to adapt to various laminating scenarios.

[0068] Furthermore, the position adjustment mechanism 40 of this embodiment also includes a connecting frame 43 fixed to the third bracket 42 and connected to the output end of the second driving device 41, a first guide rail 44 fixed to the second bracket 32, and a first slider 45 fixed to the third bracket 42 and slidably matched with the first guide rail 44. Through the arrangement of the first guide rail 44 and the first slider 45, the stability of the movement of the third bracket 42 along the y direction is improved.

[0069] In addition, in the actual processing, since the melamine board 92 is placed at an angle offset on the xy plane, and the facial tissue 94 is stacked and placed on the storage table 93 at a standard angle, if the seventh driving device 83, the lifting mechanism 20 and the clamping mechanism 60 directly clamp the facial tissue 94 and lay it flat on the surface to be bonded of the melamine board 92, it is easy for the facial tissue 94 to be misaligned with the melamine board 92. Based on this problem, please refer to Figure 7 and Figure 8 The melamine board paper laying production line of this embodiment is further provided with an angle adjustment mechanism 50, through which the placement angle of the surface paper 94 on the xy plane can be adjusted to adapt to various laminating scenarios.

[0070] The angle adjustment mechanism 50 of this embodiment also includes a first right-angle frame 56 for connecting the output end of the third driving device 51 and the first mounting frame 53, two first self-aligning bearings 57 fixed to the first mounting frame 53, a second right-angle frame 58 for connecting the output end of the fourth driving device 52 and the second mounting frame 54, and two second self-aligning bearings 59 fixed to the second mounting frame 54. The two ends of the rotating shaft 55 along the y direction are respectively matched with the first self-aligning bearing 57 and the second self-aligning bearing 59 on the same side. Through the linkage of the third driving device 51 and the fourth driving device 52, the positions of the first mounting frame 53 and the second mounting frame 54 along the x direction are adjusted. When the displacements of the first mounting frame 53 and the second mounting frame 54 are different, the two rotating shafts 55 can no longer be parallel to the y axis, thereby realizing the adjustment of the placement angle of the facial paper 94 on the xy plane.

[0071] It should be added that, since the third driving device 51 drives the first mounting frame 53 along a straight line, the fourth driving device 52 drives the second mounting frame 54 along a straight line, and the two rotating shafts 55 are connected between the first mounting frame 53 and the second mounting frame 54, in order to adjust the placement angle of the two rotating shafts 55 on the xy plane, this embodiment provides a first self-aligning bearing 57 and a second self-aligning bearing 59. The first self-aligning bearing 57 and the second self-aligning bearing 59 can adapt to the deviation or inclination between the two rotating shafts 55 and the seat hole while bearing radial and axial loads, thereby achieving smooth adjustment.

[0072] Furthermore, the angle adjustment mechanism 50 of the present embodiment also includes a second guide rail 510 fixed to the third bracket 42, a second slider 511 fixed to the first mounting frame 53 and slidingly matched with the second guide rail 510 along the x-direction, a third guide rail 512 fixed to the third bracket 42, and a third slider 513 fixed to the second mounting frame 54 and slidingly matched with the third guide rail 512 along the x-direction; by providing the second guide rail 510 and the second slider 511, the stability of the movement of the first mounting frame 53 along the x-direction is improved; by providing the third guide rail 512 and the third slider 513, the stability of the movement of the second mounting frame 54 along the x-direction is improved.

[0073] For further information, please refer to Fig.13 The clamping mechanism 60 of this embodiment also includes two sixth driving devices 63 for driving the two rotating shafts 55 to rotate respectively, two sixth bearing seats 64 fixed to the second mounting frame 54, and a third rotating shaft 65 fixed to the sixth driving device 63 and rotatably matched with the sixth bearing seat 64. The rotation of the two rotating shafts 55 can be controlled by the two sixth driving devices 63, thereby driving the adsorption ends of the two rows of suction cups 62 to be set downward or the adsorption ends to be set opposite to each other. When the adsorption ends of the two rows of suction cups 62 are set downward, they can be used to adsorb facial paper 94; when the adsorption ends of the two rows of suction cups 62 are set opposite to each other, they can be used to clamp the facial paper 94, thereby improving the clamping stability of the facial paper 94.

[0074] Furthermore, the suction cup frame 61 is also provided with a blowing member 66, and the blowing direction of the blowing member 66 is parallel to the suction direction of the suction cup 62. By providing the blowing member 66, while the suction cup 62 sucks the upper layer of paper 94, the blowing member 66 can be used to blow air toward the bottom of the upper layer of paper 94 to separate the upper layer of paper 94 from the lower layer of paper 94, thereby preventing the lower layer of paper 94 from being lifted up.
