[0001] The utility model relates to the technical field of veneer lathes, in particular to an intelligent wood processing production line. Background Art

[0002] In wood processing, the function of a veneer lathe is to veneer a wooden core within a certain diameter range into single wood board pieces of different thicknesses; generally, a veneer lathe is usually used in conjunction with a conveyor. The single wood board pieces are veneered from a cylindrical wooden core, so that the surface of the single wood board pieces is affected by the original outer shape and becomes curved and uneven, and the thinner single wood board pieces are easily bent and broken. Therefore, the single wood board pieces are generally sorted and stacked manually.

[0003] As can be seen from the above, the single wood board pieces are generally stacked manually, and the automatic stacking of the single wood board pieces cannot be realized. In view of this, an intelligent wood processing production line is proposed in this article. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0023] Referring to the attached Figures 1-5 , an intelligent wood processing production line includes a veneer lathe 1. Below the discharge port of the veneer lathe 1, a conveyor 2 is in contact setting. At the same time, the upper surface of the conveyor 2 is slightly lower than the lower end edge of the discharge port of the veneer lathe 1, and the conveying speed of the conveyor 2 is greater than the discharging speed of the veneer lathe 1. That is, the discharging speed of the veneer lathe 1 for cutting a cylindrical wood core into equidistant single wood sheets is less than the conveying speed of the conveyor 2. That is to say, after the single wood sheets produced by the veneer lathe 1 are discharged onto the conveyor 2, multiple single wood sheets on the conveyor 2 will be arranged in an equidistant straight line due to the differential speed between the veneer lathe 1 and the conveyor 2. A stationary table 3 of equal height is fixedly installed on the end bracket of the conveyor 2.

[0024] In this embodiment, a palletizing robot 4 is provided at the end of the conveyor 2. At the end of the palletizing robot 4, eighteen vacuum discs 6 are connected through a connecting box plate 5. The eighteen vacuum discs 6 are arranged in a 3×6 matrix on the lower surface of the connecting box plate 5, and the cross-section of the connecting box plate 5 is the same as the upper surface size of the single wood sheet.

[0025] In this embodiment, ten pressure sensors 8 are fixedly installed on the lower surface of the connecting box plate 5. The lower surfaces of the suction cups 601 and the pressure sensors 8 are the same. The ten pressure sensors 8 are mainly used to detect the pressure between the suction cups 601 and the single wood sheet. That is, when the pressure detected by the pressure sensors 8 is greater than the preset pressure, the pressure sensors 8 are used to feedback a signal to the palletizing robot 4 to stop the suction cups 601 from pressing the single wood sheet further. The ten pressure sensors 8 and the palletizing robot 4 are connected for signal through wires and a controller to prevent the suction cups 601 from damaging the single wood sheet. A vision camera 7 is fixedly installed on one side of the connecting box plate 5. The vision camera 7 faces vertically downward and is mainly used to obtain the vision of the connecting box plate 5 for the single wood sheets below, so as to judge whether the single wood sheet has defects, so that the palletizing robot 4 can stack the complete and defective single wood sheets separately, into a defective stacking area or a complete area, and assist the palletizing robot 4 to align the connecting box plate 5 with the single wood sheet below.

[0026] In this embodiment, the vacuum disc 6 includes a suction cup 601 and a nozzle 606. The nozzle 606 is coaxially and fixedly installed inside the suction cup 601. The lower surface of the nozzle 606 is higher than the lower surface of the suction cup 601. The oil outlet of the nozzle 606 is vertically downward, mainly for spraying the wood protection oil in a conical shape. The top of the suction cup 601 is reinforced and fitted with a circular plate 608. A distance measuring sensor 607 is fixedly installed on the circular plate 608 and the suction cup 601. The distance measuring sensor 607 is also connected to the above-mentioned controller through a wire for signal connection. The distance measuring sensor 607 is mainly used to detect the distance between the suction cup 601 and the single wood board piece below;

[0027] The top of the nozzle 606 is fixedly connected to a connecting pipe 605. The connecting pipe 605 fixedly passes through the suction cup 601 and the circular plate 608. The nozzle 606 is connected to the wood protection oil through a high-pressure electric oil pump. And the oil outlet of the high-pressure electric oil pump is fixedly connected to eighteen solenoid valves I through a distributor. The oil inlet of the high-pressure electric oil pump is connected to the wood protection oil. The oil outlets of the eighteen solenoid valves I are respectively connected to the tops of the eighteen connecting pipes 605 through oil pipes. And the high-pressure electric oil pump and the eighteen solenoid valves I are also connected to the above-mentioned controller through wires for signal connection. When the eighteen vacuum discs 6 are pressed down close to the single wood board piece below, that is, the lower surface of the suction cup 601 does not contact the single wood board piece, but the nozzle 606 can just spray the wood protection oil in a conical shape onto the single wood board piece directly below the outer circle of the suction cup 601, set the first distance;

[0028] When the distance measuring sensors 607 of the vacuum discs 6 in at least two rows detect that the distance between the suction cup 601 and the single wood board piece reaches and is slightly less than the first distance, because the single wood board piece is sliced by rotary cutting, the upper surface of the sliced single wood board piece is uneven. Therefore, only the distance measuring sensors 607 of the vacuum discs 6 in one row detect the single wood board piece, which may be because the single wood board piece here protrudes upward. Therefore, the distance measuring sensors 607 of the vacuum discs 6 in at least two rows transmit signals to the connected solenoid valves I to open the oil circuit and transmit start signals to the high-pressure electric oil pump. When the high-pressure electric oil pump starts, the high-pressure electric oil pump is used to pump the wood protection oil and then spray the wood protection oil below the vacuum discs 6 that detect the first distance through the opened solenoid valves I. The wood protection oil sprayed on the above-mentioned single wood board piece can form an oil film between the suction cup and the single wood board piece, increasing the sealing between the suction cup 601 and the single wood board piece.

[0029] In this embodiment, the top end of the suction cup 601 is connected to a negative pressure suction power source. An annular box 602 is fixedly installed above the circular plate 608. Three uniformly distributed circular tubes 604 are connected and arranged below the annular box 602. The lower ends of the circular tubes 604 communicate with the inner cavity of the suction cup 601. A pipe joint 603 is connected above the annular box 602. The annular box 602 is fixedly connected to the connecting box plate 5. The negative pressure suction power source is specifically composed of a vacuum pump and a sealed box. The suction port of the vacuum pump communicates with the sealed box. The sealed box is evacuated by the working vacuum pump to form a negative pressure space with a suction function inside the sealed box. This negative pressure space is connected to an air path diverter through a gas guide pipe. The eighteen suction ports of the air path diverter are respectively connected to solenoid valves II. The vacuum pump and the eighteen solenoid valves II are respectively connected to a controller through wires. The suction ports of the eighteen solenoid valves II are respectively connected to the pipe joints 603 in the eighteen vacuum discs 6 through eighteen gas guide pipes;

[0030] When two or more pressure sensors 8 detect that the preset pressure is reached between the multiple vacuum discs 6 and the single wood board, that is, when the suction cup 601 outside the above-mentioned wood protection oil spraying nozzle 606 contacts the single wood board below, the distance detected by the distance sensor 607 at this time is the second distance. The distance sensor 607 and the pressure sensor 8 can transmit an opening signal to the vacuum pump and the multiple solenoid valves II through the controller. That is, only the vacuum disc 6 for oil spraying can generate suction and firmly suck the single wood board below, while the vacuum discs 6 on the defective parts of the single wood board will not spray oil or suck air. The above-mentioned sprayed wood protection oil is mainly used to increase the sealing performance between the suction cup 601 and the single wood board.

[0031] It should be noted that the peeling machine 1, the conveyor 2, the palletizing robot 4, the distance sensor 607, the vision camera 7, the pressure sensor 8, the solenoid valve I, the solenoid valve II, the vacuum pump and the high-pressure electric oil pump are respectively connected to an external power source through wires.

[0032] In this utility model, after the single wood board slices produced by the rotary cutting of the rotary cutting machine 1 reach the stationary table 3 statically, the palletizing robot 4 can identify the position and defects of the single wood board slices below through the vision camera 7, and vertically align the lower ends of the eighteen vacuum discs 6 below the connecting box board 5 with the single wood board slices, and press down vertically. The distance measuring sensors 607 in the eighteen vacuum discs 6 are used to detect the distance to the single wood board slices. When the distance measuring sensors 607 in the two rows detect the first distance or a distance less than the first distance, the vacuum discs 6 can avoid the defective parts of the single wood board slices below and spray wood protection oil, and then continue to press down the eighteen vacuum discs 6 until more than two pressure sensors 8 detect that the preset pressure is reached between the multiple vacuum discs 6 and the single wood board slices. The distance measuring sensors 607 and the pressure sensors 8 can transmit an opening signal to the vacuum pump and multiple solenoid valves II through the controller, that is, only the vacuum discs 6 that spray oil can generate suction and firmly suck the single wood board slices below. Then, the palletizing robot 4 can place the sucked single wood board slices in the defective palletizing area or the complete area, so as to realize the automatic sorting and palletizing of several single wood board slices. The vacuum discs 6 with defective parts on the single wood board slices will not spray oil or suck air. The above-mentioned sprayed wood protection oil is mainly used to increase the sealing performance between the suction cup 601 and the single wood board slices.

[0033] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
