Description

Technical Field

[0001] The utility model relates to the technical field of plate processing and manufacturing, in particular to a paper suction component and a paper laying device. Background Art

[0002] Currently, the production technology for artificial board veneer is relatively mature. Decorative paper is picked up by a paper-laying trolley and then moved to the corresponding surface of the slab for application. Decorative paper is stacked on a paper storage mechanism. The trolley then uses an array of vacuum suction cups to pick up each sheet individually before moving it onto the slab. During this process, each time a sheet is lifted, it inevitably exerts a slight suction force on the next sheet. Even with precise suction control, the tension between adjacent sheets can interfere with each other. As a result, when a sheet is lifted by the suction cups, the next sheet is also lifted, then falls under the influence of gravity. This inevitably causes the next sheet to shift, leading to skew. Consequently, each sheet of decorative paper placed on the slab is positioned differently, and some sheets can even be so skewed that they fail to fully cover the slab. Therefore, additional personnel are required at this station to inspect the decorative paper placed on the slab. If severe skew is detected, manual intervention is required to straighten the paper, increasing labor costs. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] (Example 1)

[0032] like Figures 1 to 3 The paper laying device shown includes a frame 1, a paper laying sports car 2 and a paper suction assembly 3, wherein the paper laying sports car 2 is arranged on the top of the frame 1 and can reciprocate in the horizontal direction. A pair of hanging frames 4 arranged vertically downward are fixedly installed at the bottom of the paper laying sports car 2, and a connecting frame 5 is fixedly connected between the bottoms of the two hanging frames 4. The paper suction assembly 3 can be installed on the connecting frame 5 in a liftable manner, thereby realizing the basic paper laying function. Through horizontal and vertical movement, the papers on the decorative paper stack are sucked up one by one and sent to the board.

[0033] Specifically, a belt conveyor 6 is fixedly provided on the top of the frame 1. The belt conveyor 6 includes two conveyor belts located on both sides of the paper-laying car 2, and the transmission direction is the same as the movement direction of the paper-laying car 2. A pair of crossbeams 1-1 arranged parallel to the conveyor belts are fixedly provided on the top of the frame 1. A chute 1-1-1 is provided on one side of the crossbeam 1-1 near the center of the paper-laying car 2. The paper-laying car 2 includes a frame 2-1. Rollers 2-2 are symmetrically mounted on both sides of the frame 2-1 for rotation. A limit portion 2-3 is provided at the bottom with a gap located within the chute 1-1-1, thereby limiting the reciprocating motion path of the paper-laying car 2 and preventing derailment during movement. The outer peripheral surface of the roller 2-2 contacts the upper surface of the crossbeam 1-1, achieving rolling friction between the paper-laying car 2 and the frame 2-1, thereby improving the smoothness of the reciprocating movement of the paper-laying car 2. To further enhance the smooth reciprocating motion of the paper-laying car 2, the position-limiting portion 2-3 of this embodiment utilizes sliding wheels rotatably connected to the carriage 2-1, achieving both position limiting and frictional resistance. The carriage 2-1 is positioned above the belt conveyor 6 and is flanked by outwardly extending side frames 2-4. The bottoms of the side frames 2-4 are fixedly connected to the corresponding conveyor belts, enabling reciprocating motion driven by the belt conveyor 6. The overall structure is simple, the power is stable, and the position of the paper-laying car 2 is precisely controlled, improving the accuracy of its resting position.

[0034] The paper suction assembly 3 includes a horizontal frame 3-1 and a paper suction bracket 3-2 that can be movably arranged along the length direction of the horizontal frame 3-1. Connecting plates 3-3 that can be movably arranged along the length direction perpendicular to the horizontal frame 3-1 are horizontally provided at both ends of the paper suction bracket 3-2. A horizontal rod 3-4 is provided between the connecting plates 3-3. Both ends of the horizontal rod 3-4 are universally movably connected to the connecting plates 3-3. Vacuum suction cups 3-5 arranged along the length direction are fixed at the bottom to absorb the decorative paper through the vacuum suction cups 3-5.

[0035] Near both ends of the horizontal frame 3-1, vertically upward-facing vertical beams 7 are fixedly mounted. A lifting cylinder 8 is installed on the outer side of the vertical beams 7. The cylinder body of the lifting cylinder 8 is fixedly mounted on the connecting frame 5, and the end of the piston rod is vertically downward and hinged to the horizontal frame 3-1, thereby achieving the lifting and lowering of the paper suction assembly 3. A synchronization rod 9 is rotatably connected between the two vertical beams 7. Near both ends of the connecting frame 5, a pair of vertically mounted racks 10 are fixedly mounted. Gears 11 that mesh with the racks 10 are coaxially fixed to each end of the synchronization rod 9, forming a synchronization mechanism that ensures that the paper suction assembly 3 is generally horizontal, preventing the vacuum suction cups 3-5 from effectively contacting the decorative paper and improving the success rate of paper suction.

[0036] A first connecting frame 12 is located at the left end of the horizontal frame 3-1, and a second connecting frame 13 is located at each end of the paper suction bracket 3-2. Both the first connecting frame 12 and the second connecting frame 13 are assembled using a quick-locking mechanism and connecting rods, and are mounted to the horizontal frame 3-1 and the paper suction bracket 3-2, respectively, using quick-locking mechanisms. A pair of first photoelectric sensors 14 are located at the end of the first connecting frame 12, and a second photoelectric sensor 15 is located at the end of each second connecting frame 13. This allows for adjustable installation of the photoelectric sensors, facilitating equipment commissioning and accommodating the positioning of a wider range of decorative paper specifications. The line connecting the two first photoelectric sensors 14 is parallel to the horizontal frame 3-1, and therefore parallel to the edge of the properly positioned decorative paper, used to detect skew. The distance between the two second photoelectric sensors 15 is equal to the length of the decorative paper, used to detect longitudinal alignment of the decorative paper and the paper suction assembly.

[0037] A mounting plate is fixed on the horizontal frame 3-1, and a first linear drive mechanism 16 is hinged on the mounting plate. The output end of the first linear drive mechanism 16 is hinged to the paper suction bracket 3-2, thereby driving the paper suction bracket 3-2 to move along the length direction of the horizontal frame 3-1. A second linear drive mechanism 17 is hinged at both ends of the paper suction bracket 3-2, and the output end of the second linear drive mechanism 17 is hinged to the connecting plate 3-3, thereby driving the connecting plate 3-3 to move perpendicular to the length direction of the horizontal frame 3-1. The first linear drive mechanism 16 and the second linear drive mechanism 17 can be a cylinder, a hydraulic cylinder or a servo electric cylinder, and the structure is simple. In this embodiment, a servo electric cylinder is preferably used, which can more accurately control the expansion and contraction formation. Since the end of the crossbar 3-4 is universally matched with the connecting plate, when the connecting plate moves forward or backward, the crossbar 3-4 will tilt, thereby adjusting it to be parallel to the edge of the decorative paper. In this embodiment, the crossbar 3-4 and the connecting plate 3-3 are preferably connected by a universal bearing or a spherical bearing for rotation, and the structure is simple and the connection is reliable.

[0038] In order to improve the stability of linear motion, in this embodiment, a first guide mechanism 18 arranged horizontally and parallel to the horizontal frame 3-1 is connected between the horizontal frame 3-1 and the paper suction bracket 3-2, and a second guide mechanism 19 arranged horizontally and parallel to the connecting plate 3-3 is connected between the connecting plate 3-3 and the paper suction bracket 3-2. Both the first guide mechanism 18 and the second guide mechanism 19 are linear guide rails with a simple structure.

[0039] In order to prevent the decorative paper from tilting when the vacuum cup 3-5 breaks the vacuum, this embodiment provides a liftable paper pressing rod 3-6 on the side of the paper suction bracket 3-2 away from the cross bar 3-4, so as to press the decorative paper after it is placed on the board. The lifting and lowering of the paper pressing rod 3-6 is also controlled by a cylinder, which is a relatively conventional drive structure design and will not be described in detail herein.

[0040] The workflow of this embodiment is as follows:

[0041] The paper-laying car 2 drives the paper suction assembly 3 to move horizontally above the decorative paper stack. The paper suction assembly 3 descends under the action of the lifting cylinder 8. When one of the first photoelectric sensors 14 detects the edge of the decorative paper, the decorative paper is sucked up by the vacuum suction cup 3-5, and the inclination angle of the cross bar 3-4 is adjusted by the second linear drive mechanism 17 until the other first photoelectric sensor 14 also detects the decorative paper. At this time, the skew state of the decorative paper has been corrected.

[0042] Then, the two second photoelectric sensors 15 and the first linear drive mechanism 16 cooperate to complete the alignment of the decorative paper in the length direction, and thus the entire correction is completed.

[0043] Finally, the paper laying car 2 drives the paper suction assembly 3 to deliver the decorative paper to the board. The paper pressing rod 3-6 descends to press the decorative paper and fix it, and then the vacuum is broken to complete the whole process.

[0044] In this embodiment, the paper suction assembly 3 detects the position of the decorative paper through two pairs of photoelectric sensors, and the movement of the paper suction bracket 3-2 drives the synchronous movement of the cross bar 3-4 to ensure that the arranged vacuum suction cups 3-5 are centered in the length direction of the decorative paper. By optimizing the connection relationship between the cross bar 3-4 and the connecting plate 3-3, a movable connection is achieved. The movement of the connecting plate 3-3 adjusts the skew angle of the cross bar 3-4 in the horizontal direction, thereby ensuring that the arranged vacuum suction cups 3-5 are parallel to the long side of the decorative paper, thereby realizing automatic correction of the relative position of the paper suction assembly 3 and the decorative paper, so that each piece of decorative paper placed on the board can be straightened, eliminating manual intervention and saving labor costs.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention.
