Description

Technical Field

[0001] The invention relates to the technical field of plate production equipment, and in particular to single plate vacuum adsorption and transportation equipment. Background Art

[0002] In the traditional production of wood-based panels, the stacking and use of wood peeled veneers (thickness 1mm-5mm) have always been mainly done manually, and the transportation, selection, and drying are mostly done manually, with low production efficiency and high labor costs. Due to the small thickness and soft texture of veneers, it is difficult to use manipulators to operate single sheets, especially the feeding of veneer drying (i.e., continuous feeding of single sheets into the dryer, and then continuous stacking of single sheets out of the dryer), continuous splicing and loading of veneer splicing machines, and loading and gluing of gluing machines all rely on manual operation, which is slow and labor-intensive.

[0003] In recent years, many people have developed mechanical loading of single boards. Most designs use manipulators and suction cups as the main structure. They can run at low speeds and can be used for small boards smaller than 680mm*1280mm. However, after being spliced ​​into large boards of 1280mm*2500mm, the structure of manipulators and suction cups is unable to cope with the situation and the speed is slow (2-3 sheets / minute). Usually, after the manipulator picks up a single board, it has to move forward one station (about 3 meters), put it into the glue coating machine into the board rack, and then put it down and return to the board stacking station to transport the next single board. There are invalid strokes. Due to the large overall weight of the manipulator and the short running distance, it is difficult to achieve high-speed production. At the same time, the configuration cost of the manipulator is also very high. Usually, the cost of a manipulator plus suction cup kit exceeds 50,000 yuan. Obviously, the manipulator solution cannot meet the current development needs of industrial automation. Summary of the invention

[0004] The purpose of the present invention is to provide a single board vacuum adsorption transportation equipment to solve the above-mentioned technical problems.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is:

[0013] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] Example:

[0015] The single board vacuum adsorption and transportation equipment described in this embodiment includes an equipment body and a vacuum pump.

[0016] Reference Figure 1-2 The main body of the equipment includes a main frame and a conveyor belt mechanism; the main frame is a frame structure, consisting of four parallel rectangular tubes 1 and two short square tubes fixed at the front and rear ends of the rectangular tubes 1. The number of rectangular tubes 1 used is set according to the thickness and weight of the transported single board.

[0017] The bottom surface of the rectangular tube 1 is uniformly provided with a plurality of through holes 15 along its length direction; the conveyor belt mechanism comprises at least two conveyor belts 9 corresponding to the rectangular tubes 1 one by one and a conveyor belt driving device. The conveyor belt 9 is uniformly provided with a plurality of rows of micro holes 91 along its length direction; the conveyor belt 9 is mounted on the rectangular tube 1 along its length direction, and circulates along the length direction of the rectangular tube 1 under the drive of the conveyor belt driving device; the rectangular tube 1 is connected to a vacuum pump, and when the vacuum pump evacuates the rectangular tube 1, the through holes 15 on the bottom surface of the rectangular tube 1 are connected with the micro holes 91 on the conveyor belt, and the bottom surface of the conveyor belt 9 generates an adsorption force to adsorb the single board.

[0018] The conveyor belt driving device includes a driving motor 3 and a transmission shaft 5. The driving motor 3 is fixed on the motor seat 2 above the tail of the main frame. The tail of the main frame is fixedly installed with a rear bracket 6, and the front end is fixedly installed with a front bracket 8; the transmission shaft 5 is installed at the top of the rear bracket 6, and a transmission wheel and a plurality of conveyor belt driving wheels 51 are fixedly installed on the transmission shaft 5, and the power output end of the driving motor 3 drives the transmission wheel through the transmission belt 4; the lower tail end of the rear bracket 6 is installed with a rear guide wheel shaft 7, and a plurality of rear guide wheels 71 are installed on the rear guide wheel shaft 7; a plurality of tensioning wheels 61 that can be adjusted forward and backward are installed in the middle of the front end of the rear bracket 6; a front guide wheel shaft 81 is installed on the front bracket 8, and a plurality of front guide wheels 82 corresponding to the rear guide wheel 71 are installed on the front guide wheel shaft 81; each conveyor belt 9 is respectively assembled on the corresponding conveyor belt driving wheel 51, the rear guide wheel 71 and the front guide wheel 82, and the tension is adjusted by the tensioning wheel 61.

[0019] The inner cavities of the four rectangular tubes 1 are divided into a loading area 11, a transportation area 12 and a discharge area 13 from the back to the front by two partition plates 14; the loading areas 11 of each rectangular tube 1 are interconnected and connected to a vacuum pump; the transportation areas 12 of each rectangular tube 1 are interconnected and connected to a vacuum pump; the discharge areas 13 of each rectangular tube 1 are interconnected and connected to a vacuum pump. The vacuum degree of the three functional areas is independently controlled by three vacuum pumps, thereby realizing the functions of loading, transportation and discharge.

[0020] When the single board 10 approaches the conveyor belt corresponding to the loading area 11, the passage formed by the numerous micropores 91 on the conveyor belt and the through holes at the corresponding positions on the rectangular tube is blocked by the single board, and a vacuum area is formed between the upper surface of the single board 10 and the conveyor belt 9. The single board 10 is adsorbed on the conveyor belt 9, and the conveyor belt 9 is driven by the driving motor 3, and the conveyor belt 9 drives the single board 10 to move forward; when the single board 10 moves to the unloading area 13 with the conveyor belt 9, due to the low vacuum degree of the unloading area 13, the adsorption force on the single board 10 is less than the gravity of the single board 10, thereby completing the unloading and realizing the automatic and rapid transmission of the single board. The transmission speed can be achieved at 2-6 seconds per sheet (when the length of the single board is 640mm-2500mm), which is more than ten times faster than that of the robot.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, which are only used to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
