Description

Technical Field

[0001] The utility model relates to the technical field of sheet processing and manufacturing, in particular to an automatic sheet laying device. Background Art

[0002] With the gradual increase in the price of solid wood, more and more people choose to use artificial boards with a higher environmental protection level as decoration materials. Most artificial boards are formed by pressing wood chips into sheets, and then veneer paper is adhered to the surface of the sheets to form paint-free boards with various surface patterns. When processing such paint-free boards, first, the sheets need to be sent to the processing surface of the board loading machine. With the rapid development of automation, more and more sheet processing manufacturers use automatic sheet laying trolleys to replace manual labor to horizontally translate the sheets conveyed by the previous conveyor to the board turning machine. However, the conveying plane of the conveyor is a horizontal plane, while the processing surface of the board loading machine is an inclined plane. The traditional automatic sheet laying trolley can only achieve horizontal translation. When the sheet is placed on the board loading machine, one side contacts the processing surface, and there is a large height difference between the other side and the processing surface. When the adsorption force of the sheet laying trolley is withdrawn, the other side of the sheet will have a large impact on the processing surface of the board loading machine, not only generating a large noise, but also causing the sheet to displace, requiring additional manual alignment. Even the surface of the sheet may be damaged after the impact, resulting in defective products. In the long term, there is also a certain risk of damage to the board loading machine. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an automatic sheet laying device for the deficiencies of the prior art, which can automatically move the horizontally placed sheet to the inclined processing surface of the board loading machine and fit it with the processing surface, eliminate the height difference, avoid the impact of the sheet on the processing surface of the board loading machine, reduce noise, effectively protect the sheet and the board loading machine, and improve the qualified rate of sheet processing.

[0004] The technical solution to achieve the purpose of the utility model is as follows:

[0005] An automatic sheet laying device includes a frame and a sheet laying trolley arranged on the top of the frame and capable of reciprocating horizontally. A bracket that can be lifted and lowered longitudinally is suspended on the sheet laying trolley.

The belt conveyor includes two conveyor belts located on both sides of the planking carriage. The planking carriage is located above the belt conveyor and is fixedly connected to the corresponding conveyor belts on both sides respectively.

[0011] Furthermore, a guide post arranged in the vertical direction is fixedly arranged on the planking carriage. The bracket penetrates through the guide post with a gap.

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings of the specification and specific embodiments.

[0034] (Embodiment 1)

[0036] Specifically, a belt conveyor 6 is fixedly provided at the top of the frame 1. The belt conveyor 6 includes two conveyor belts located on both sides of the platen carriage 2, and the transmission direction is the same as the moving direction of the platen carriage 2. A pair of crossbeams 1-1 parallel to the conveyor belts are fixedly provided at the top of the frame 1. A chute 1-1-1 is provided on the side of the crossbeam 1-1 close to the center of the platen carriage 2. The platen carriage 2 includes a frame 2-1. Roller wheels 2-2 are symmetrically and rotatably installed on both sides of the frame 2-1. A limiting portion 2-3 with a gap at the bottom is located in the chute 1-1-1, thereby limiting the reciprocating movement path of the platen carriage 2 and preventing derailment during movement. The outer peripheral surface of the roller wheel 2-2 is in contact with the upper surface of the crossbeam 1-1, realizing the rolling friction between the platen carriage 2 and the frame 2-1 and improving the smoothness of the reciprocating movement of the platen carriage 2. To further improve the smoothness of the reciprocating movement of the platen carriage 2, the limiting portion 2-3 in this embodiment adopts a sliding wheel rotatably connected to the frame 2-1, reducing the frictional resistance while realizing the limit. The frame 2-1 is located above the belt conveyor 6, and connecting brackets 2-4 extending outward are provided on both sides. The bottom of the connecting bracket 2-4 is fixedly connected to the corresponding conveyor belt, thereby realizing the reciprocating movement under the action of the belt conveyor 6. The overall structure is simple, the power is stable, it is convenient to accurately control the position of the platen carriage 2, and the accuracy of the stopping position of the platen carriage 2 is improved.

[0037] A lifting mechanism 7 is provided at the bottom of the platen carriage 2. The lifting mechanism 7 is a linear drive mechanism, and its fixed end and free end are respectively hinged to the platen carriage 2 and the plate suction assembly 4. The lifting is realized through the telescoping of the linear drive mechanism. The structure is simple and the control is convenient. A guide post 8 arranged in the vertical direction is fixedly provided on the platen carriage 2. The bracket 3 passes through the guide post 8 with a gap, thereby limiting the lifting of the bracket 3 and ensuring that it always moves in the vertical direction, preventing the plate suction assembly 4 at the lower end from shaking and improving the position accuracy of the placed plate. The linear drive mechanism can be a cylinder, a hydraulic cylinder or an electric cylinder to meet the requirements of different workshop sites. In this embodiment, a cylinder is adopted. Through grooves 8-1 are symmetrically provided at the upper and lower ends of the guide post 8. Guide wheels 9 rotatably installed on the guide post 8 are provided in the through grooves 8-1. The outer peripheral surface of the guide wheel 9 is in contact with the bracket 3, thereby reducing the frictional resistance during the lifting of the bracket 3, improving the smoothness of the lifting movement, reducing the load of the lifting mechanism 7 at the same time, and prolonging the service life.

[0038] The flipping mechanism 5 also adopts a linear drive mechanism. In this embodiment, a cylinder is selected. The fixed end and the free end of the linear drive mechanism are respectively hinged to the bracket 3 and the suction plate assembly 4, so as to drive the suction plate assembly 4 to flip through the telescopic action of the linear drive mechanism. The suction plate assembly 4 includes a suction plate frame 4-1 and vacuum suction nozzles 4-2 symmetrically suspended on both sides of the suction plate frame 4-1. The sheets are adsorbed through the vacuum suction nozzles 4-2. The structure is simple, the adsorption force is strong, the safety performance is excellent, and at the same time, the surface of the sheets will not be worn. A buffer assembly 4-3 is provided on the side of the suction plate frame 4-1. The buffer assembly 4-3 includes a sleeve fixedly installed on the suction plate frame 4-1 and a connecting shaft elastically inserted into the sleeve longitudinally. The lower end of the connecting shaft is lower than the lower end of the vacuum suction nozzle 4-2 and is fixedly installed with a rubber buffer pad. By adding the buffer assembly 4-3, when the suction plate assembly 4 descends to be about to contact the sheets, a certain buffering effect is achieved, so that the vacuum suction nozzles 4-2 and the sheets can contact slowly, avoiding impact and damaging the surface of the sheets or the vacuum suction nozzles.

[0039] In this embodiment, the boarding car 2 that reciprocates in the horizontal direction drives the suction plate assembly 4 to translate through the bracket 3, and the bracket 3 drives the suction plate assembly 4 to lift, so as to realize the basic function of automatically transferring the sheets. By adding the flipping mechanism 5 and optimizing the connection method between the suction plate assembly 4 and the bracket 3 into a rotational connection, furthermore, the side-mounted flipping mechanism 5 drives the entire suction plate assembly 4 to flip in the horizontal direction to form an inclination angle, ensuring that the sheets adsorbed by the suction plate assembly 4 can be parallel to the processing surface of the sheet loading machine, so that the height difference on both sides can be eliminated when the sheets fall, thus avoiding the impact between the sheets and the processing surface of the sheet loading machine, reducing noise, effectively protecting the sheets and the sheet loading machine at the same time, and improving the qualified rate of sheet processing.
