DETAILED DESCRIPTION

[0030] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the event of a change in position.

[0031] Existing transport devices for conveying wooden boards are generally only for flat wooden boards, and the flat wooden boards are directly transported by conveyor belts. They have poor adaptability when transporting some curved wooden boards. At the same time, the curved wooden boards are also easy to shake along their curved surfaces on the transport devices, causing damage to the wooden boards.

[0032] Embodiment 1: A sheet material automatic conveying and transferring device, Figure 1-Figure 4 As shown, it includes a support frame 1, an electric conveyor belt 11 is arranged in the middle of the support frame 1, two groups of symmetrically distributed first hydraulic rods 12 are fixedly connected to the support frame 1, and the telescopic ends of the two symmetrically distributed first hydraulic rods 12 are commonly fixedly connected to a first fixed plate 13, the middle part of the upper side of the first fixed plate 13 is cylindrical, and the first fixed plate 13 is rotatably connected to a rotating plate 14. When in use, the rotating plate 14 rotates around the middle part of the adjacent first fixed plate 13, and a second hydraulic rod 15 is fixedly connected to the upper side of the first fixed plate 13, and the telescopic end of the second hydraulic rod 15 is spherical. The second hydraulic rod 15 is slidably connected to the rotating plate 14 through the spherical telescopic end. The second hydraulic rod 15 is used to fix the rotating plate 14, and the rotation of the rotating plate 14 is controlled by the telescopic end of the second hydraulic rod 15. A transmission mechanism is arranged on the upper side of the rotating plate 14, and the transmission mechanism is used to drive the arc-shaped wooden board to move. A detection mechanism for detecting the shape of the arc-shaped wooden board is arranged on the upper side of the support frame 1.

[0033] by Figure 4-Figure 6 As shown, the transmission mechanism includes two electric rotating shafts 2 which are symmetrically distributed on the left and right. The two electric rotating shafts 2 which are symmetrically distributed on the left and right are commonly arranged on the upper side of the adjacent rotating plate 14 through a bracket. The electric rotating shaft 2 is fixedly connected with two sprocket wheels 21 which are symmetrically distributed front and back. A chain 22 is transmission-connected between the sprocket wheels 21 corresponding to the two symmetrically distributed electric rotating shafts 2. An inner transmission belt 23 is commonly fixedly connected to the outer sides of the two chains 22 which are symmetrically distributed front and back. A first rotating roller 24 is fixedly connected to the middle of the electric rotating shaft 2. The first rotating roller 24 is located between the two sprocket wheels 21 on the adjacent electric rotating shafts 2. The rotating plate 14 is fixedly connected with two support rods 25 which are symmetrically distributed on the left and right. Two first limiting rods 26 which are symmetrically distributed front and back are fixedly connected between the two support rods 25 which are symmetrically distributed on the left and right. The two support rods 25 and the two first limiting rods 26 on the same transmission mechanism form a rectangular frame. A uniformly distributed second rotating roller 27 is rotationally connected between the two symmetrically distributed first limiting rods 26. The second rotating roller 27 contacts and cooperates with the adjacent inner transmission belt 23. The second rotating roller 27 is used to support the inner transmission belt 23.

[0034] by Figure 5 and Figure 6As shown, a conveying shell 3 is fixedly connected to the middle part of the outer side surface of the inner transmission belt 23. The conveying shell 3 is made of soft material, the cross-section of the conveying shell 3 is m-shaped, and the edge part of the conveying shell 3 is U-shaped. The part of the M-shaped middle part of the conveying shell 3 connected to the inner transmission belt 23 cannot be stretched outward, but can be bent. The first limiting rod 26 is slidingly connected with the second limiting rods 31 distributed equidistantly, and the second limiting rods 31 can only move up and down in the adjacent first limiting rods 26. The second limiting rods 31 are rotatably connected with the first limiting columns 32. The first limiting columns 32 are squeezed and matched with the adjacent conveying shells 3. The first limiting columns 32 are located in the adjacent U-shaped grooves of the adjacent conveying shells 3, which are used to limit the edge of the conveying shell 3. The support rod 25 is fixedly connected to two third limiting rods 311 through a square block. The third limiting rods 311 The second limiting column 321 is rotatably connected, and the second limiting column 321 is squeezed and matched with the adjacent conveying shell 3. The second limiting column 321 is located in the adjacent U-shaped groove of the adjacent conveying shell 3. The second limiting column 321 makes the left and right parts of the upper side of the conveying shell 3 flat. The support rod 25 on the right side is fixedly connected with two third hydraulic rods 33 symmetrically distributed front and back. The telescopic end of the third hydraulic rod 33 is fixedly connected with a fourth limiting rod 34. The fourth limiting rod 34 slides in the adjacent first limiting rod 26. The fourth limiting rod 34 is squeezed and matched with the adjacent second limiting rod 31. The fourth limiting rod 34 is provided with equidistantly distributed inclined surfaces, and the inclined surfaces correspond to the adjacent second limiting rod 31. The direction of the inclined surface is inclined downward from right to left, and the second limiting rod 31 is moved up and down by the movement of the fourth limiting rod 34.

[0035] by Figure 5 and Figure 6 As shown, the upper and lower sides of the first limit rod 26 are fixed with equidistantly distributed fixing frames 35, and the equidistantly distributed fixing frames 35 are commonly fixed with a second fixing plate 36, and the second fixing plate 36 cannot be deformed. The second fixing plate 36 is located between the adjacent conveying shell 3 and the adjacent inner transmission belt 23, and the second fixing plate 36 is limitedly cooperated with the adjacent inner transmission belt 23. The second fixing plate 36 is used to limit the movement of the inner transmission belt 23 to prevent the inner transmission belt 23 from moving when the edge of the conveying shell 3 bends, causing the inner transmission belt 23 to deform synchronously, resulting in an inaccurate bending angle of the conveying shell 3.

[0036] by Figure 1 , Figure 7 and Figure 8As shown, the detection mechanism includes a third fixed plate 4, the third fixed plate 4 is fixedly connected to the right side of the support frame 1, a fixed tube 41 is fixedly connected to the middle of the third fixed plate 4, the upper part of the fixed tube 41 is connected to the first airbag 42, the fixed tube 41 and the first airbag 42 are fixed, and are used to detect the lowest point of the plate, the third fixed plate 4 is fixedly connected to two symmetrically distributed sliding tubes 43, the two sliding tubes 43 are respectively located at the front and rear sides of the fixed tube 41, the sliding tube 43 is connected to the second airbag 44, the first airbag 42 and the second airbag 44 are used to limit the plate, the fixed tube 41 and the sliding tube 43 are slidably connected with a detection rod 45, the detection rod 45 is used to detect the shape of the plate, the detection rod 45 is rotatably connected to the limiting plate 46, the first airbag 42 and the second airbag 44 are used to limit the plate. The airbag 42 is in contact with the adjacent limiting plate 46, and the second airbag 44 is in contact with the adjacent limiting plate 46. The limiting plate 46 prevents the first airbag 42 or the second airbag 44 from sliding relative to the detection rod 45, which may damage the detection rod 45 or the airbag. A spring 47 is fixed between the sliding tube 43 and the support frame 1. The spring 47 is used to drive the adjacent sliding tube 43 to rise. The third fixed plate 4 is slidably connected to an extrusion frame 48. The extrusion frame 48 is extruded and matched with the two symmetrically distributed sliding tubes 43. Initially, the two sliding tubes 43 are fixed under the extrusion of the extrusion frame 48. The third fixed plate 4 is rotatably connected to a screw 49. The screw 49 is threadedly connected to the extrusion frame 48. The screw 49 is used to drive the extrusion frame 48 to move forward and backward.

[0037] When using the device to transport curved wooden boards, the staff first rotates the screw 49 (initially, the extrusion frame 48 limits the two sliding tubes 43, and the spring 47 accumulates force). During the rotation, the screw 49 drives the extrusion frame 48 to move backward through the thread, so that the extrusion frame 48 gradually disengages from the two sliding tubes 43, releasing the limit on the sliding tubes 43, and then the spring 47 is released, and the spring 47 drives the adjacent sliding tubes 43 to move upward, and the sliding tube 43 drives the parts on its upper side to move upward, and the spring 47 stops after being fully released.

[0038] After the spring 47 is fully released, the staff puts the curved wooden board on the electric conveyor belt 11, the first airbag 42 and the two second airbags 44. In the process of placing the curved wooden board, the curved wooden board first squeezes the two second airbags 44 to move the second airbags 44 downward, and the second airbags 44 drive the adjacent sliding tubes 43 to squeeze the adjacent springs 47. At the same time, the second airbags 44 are deformed and fit the curved wooden board. The curved wooden board squeezes the limit plate 46 through the second airbags 44 to rotate the limit plate 46. The limit plate 46 is tangent to the curved wooden board, and then the curved wooden board continues to descend and gradually contacts the first airbag 42 and the electric conveyor belt 11. The curvature of the curved wooden board is detected by three detection rods 45 and transmitted to the control terminal. The curvature is indirectly measured by the first airbag 42 and the second airbag 44 fitting the curved wooden board and the isolation of the limit plate 46 to avoid direct contact between the detector and the curved wooden board and prevent scratches on the curved wooden board.

[0039] After the arc-shaped wooden board is placed, the worker rotates the screw rod 49 in the reverse direction, and the extrusion frame 48 moves forward through the thread. The extrusion frame 48 gradually squeezes the two sliding tubes 43, and stops rotating the screw rod 49 after the two sliding tubes 43 are fixed.

[0040] After the two sliding tubes 43 are fixed, the control terminal controls the first hydraulic rod 12, the second hydraulic rod 15 and the third hydraulic rod 33 through the data transmitted by the detection rod 45. The first hydraulic rod 12 drives the first fixed plate 13 to move upward, and the first fixed plate 13 drives the parts thereon to move upward, so that the conveying shell 3 contacts the curved wooden board. The second hydraulic rod 15 is used to drive the adjacent rotating plate 14 to rotate around the middle of the adjacent first fixed plate 13, so that the upper side of the conveying shell 3 is tangent to the curved wooden board. The third hydraulic rod 33 drives the adjacent rotating plate 14 to rotate around the middle of the adjacent first fixed plate 13, so that the upper side of the conveying shell 3 is tangent to the curved wooden board. The adjacent fourth limit rod 34 moves to the left, and the inclined surface on the fourth limit rod 34 squeezes the adjacent second limit rod 31, so that the second limit rod 31 moves upward, and the second limit rod 31 drives the adjacent first limit column 32 to move upward, and the first limit column 32 drives the adjacent edge of the conveying shell 3 to move upward, so that the two sides of the conveying shell 3 are tilted, and the cross-section of the middle part of the upper side of the conveying shell 3 is completely arc-shaped, so that the upper side surface of the conveying shell 3 is completely in contact with the arc-shaped wooden board, so as to adapt to the arc surface of the arc-shaped wooden board, and thus better transport the arc-shaped wooden board.

[0041] During the upward movement of the second limit rod 31, the positions of the third limit rod 311 and the second limit column 321 remain unchanged, so that the upper side parts on the left and right sides of the conveying shell 3 are transformed from arc surfaces to planes, thereby preventing the raised conveying shell 3 from passing through the first rotating roller 24, which would cause the conveying shell 3 to be completely deformed too much and reduce its service life. At the same time, the process of the upper side of the conveying shell 3 smoothly transforming from a plane to an arc surface can also guide the arc-shaped wooden board to a certain range, thereby centering the arc-shaped wooden board.

[0042] After the upper side of the conveying shell 3 is fitted with the curved wooden board, the control terminal controls the first hydraulic rod 12, the second hydraulic rod 15 and the third hydraulic rod 33 to be closed, and then the staff starts the two electric shafts 2 and the electric conveyor belt 11. The electric conveyor belt 11 drives the curved wooden board to move, and the two electric shafts 2 also drive the curved wooden board to move. Taking the electric shaft 2 on the front side as an example, the electric shaft 2 drives the two sprockets 21 to rotate, and the sprockets 21 drive the adjacent chains 22 to rotate. The chain 22 drives the inner transmission belt 23 to rotate counterclockwise from front to rear, and the inner transmission belt 23 drives the conveying shell 3 to rotate counterclockwise, and drives the curved wooden board to rotate counterclockwise through the conveying shell 3 to transport the curved wooden board.

[0043] In the subsequent process, the staff directly places the curved wooden board to contact the curved part of the conveying shell 3, and then transports the curved wooden board.

[0044] After the transportation is completed, the staff controls the first hydraulic rod 12, the second hydraulic rod 15 and the third hydraulic rod 33 through the control terminal to reset the conveying shell 3, and at the same time close the electric conveyor belt 11 and the electric shaft 2, and then reset the sliding tube 43.

[0045] Since the curved wooden board has a special curved surface, when the curved wooden board is grabbed by a suction cup, due to the curvature of the curved wooden board, gaps are easily left during adsorption of the existing suction cup, causing the wooden board to fall off. If the suction force is increased, greater pressure will be exerted on the wooden board, which may cause damage to the wooden board.

[0046] Embodiment 2: Based on embodiment 1, Fig. 9 and Fig.10 As shown, it also includes a mounting base 5, which is fixed to the right part of the upper side of the support frame 1. The mounting base 5 is rotatably connected to a rotating rod 51, which is electrically driven and can rotate around the mounting base 5. The end of the rotating rod 51 away from the mounting base 5 is fixed to a fourth hydraulic rod 52, and the telescopic end of the fourth hydraulic rod 52 is fixed to a fourth fixed plate 53. The fourth fixed plate 53 is fixed to a symmetrically distributed fifth hydraulic rod 54, and the fifth hydraulic rod 54 is ball-connected with a sliding plate 55. The symmetrically distributed sliding plates 55 are slidably connected to an elastic plate 56 together, and the sliding plate 55 is located on the upper side of the elastic plate 56. The fourth fixed plate 53 is fixed to the elastic plate 56, and the fourth fixed plate 53 fixes the middle part of the elastic plate 56. The elastic plate 56 is provided with equidistantly distributed adsorption components.

[0047] by Figure 10-12As shown, the adsorption assembly includes an elastic frame 6, which is cross-shaped. Both sides of the elastic frame 6 are fixedly connected with symmetrically distributed cylinders. The elastic frame 6 is fixedly connected to the elastic plate 56 through a fixed plate in the middle. A symmetrically distributed square plate 61 is provided on the elastic frame 6. Four rubber shells 62 are fixedly connected to the elastic frame 6. The four rubber shells 62 are cross-shaped. The rubber shells 62 are connected to an external suction fan through a pipeline to provide suction. The elastic frame 6 is slidably connected to the elastic plate 56 through the cylinder.

[0048] In the process of placing the curved wooden board on the conveyor belt, the staff drives the rotating rod 51 to rotate through the control terminal, and the rotating rod 51 drives the parts thereon to rotate. At the same time, the control terminal controls the telescopic ends of the two fifth hydraulic rods 54 to retract through the data detected by the detection rod 45. The telescopic end of the fifth hydraulic rod 54 drives the sliding plate 55 to move upward, and the sliding plate 55 slides on the elastic plate 56. The two sliding plates 55 drive the elastic plate 56 to tilt upward, so that the curvature of the elastic plate 56 is the same as the curvature of the curved wooden board, and then the telescopic end of the fourth hydraulic rod 52 is controlled to descend until the rubber shell 62 contacts the curved wooden board.

[0049] During the bending process of the elastic plate 56, taking an elastic frame 6 as an example, the elastic plate 56 squeezes the round rod on the elastic frame 6, and the round rod slides in the elastic plate 56, while driving the elastic frame 6 to deform, so that the lower side of the elastic frame 6 bends, and the bending angle is equal to the curvature of the curved wooden board. When the elastic frame 6 is completely bent, the two square plates 61 swing synchronously.

[0050] When the rubber shell 62 contacts the curved wooden board, the staff starts the external adsorption pump to extract the gas in the rubber shell 62 to generate negative pressure to adsorb the curved wooden board. The elastic frame 6 is fitted with the rubber shell 62 to improve the adsorption effect on the curved wooden board. Fig.12 For example, the upper and lower rubber shells 62 are fixed between the two square plates 61. Since the square plates 61 do not bend or deform, they are more stable during adsorption, providing the main suction force for adsorbing the curved wooden board and preventing the curved wooden board from falling.

[0051] After the curved wooden board is adsorbed, the control terminal moves the curved wooden board to the conveyor belt through the linkage of the rotating rod 51 and the fourth hydraulic rod 52, and then injects air into the rubber shell 62 through an external adsorption pump to cancel the adsorption of the curved wooden board and place the curved wooden board on the transmission belt. After use, the staff controls the fifth hydraulic rod 54 to reset through the control terminal to complete the transportation of the curved wooden board.

[0052] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
