Description

Technical Field

[0001] The invention belongs to the technical field of furniture production, and in particular relates to a log and board clamping and conveying device. Background Art

[0002] With the improvement of people's consumption level, customized solid wood furniture is becoming more and more popular. Among them, the desktops of some solid wood office desks are produced with thick wooden boards, which are not only beautiful and natural, but also durable. At the same time, because they use a whole piece of wood, they reduce the use of adhesives and the release of harmful substances such as formaldehyde, which is more conducive to maintaining indoor air quality and preventing harmful substances from harming the human body.

[0003] Nowadays, when cutting large-diameter solid wood into boards, the logs are first placed between two tracks and fixed, and then the band saw is moved along the track to saw the logs. After the sawing is completed, a forklift is mostly used to remove the wooden board from the log. In order to prevent a dent in the middle of the table top when the table is in use, the wooden board is usually thick and heavy. This causes the wooden board to shake easily on the forklift when the forklift is used to transport the long and thick wooden board, posing a safety hazard. At the same time, when the forklift's fork is inserted between the wooden board and the log below, due to the heavy weight of the wooden board, the fork is easy to push the wooden board when inserted under the wooden board, causing the wooden board to slip from the log and fall to the ground, which can easily cause damage to the wooden board. At the same time, when the fork is in the process of forking the wooden board, the upper wooden board squeezes the fork, causing the fork to leave dents on the wooden board ground and the top surface of the log. When the dent is deep, it will cause more processing waste, and then cause property loss to the company. Summary of the invention

[0012] Preferably, the lifting part also includes a limit frame slidably connected to the track, the side of the hanger away from the sawing part is fixedly connected to an attraction plate, the side of the limit frame is fixedly connected to an electromagnet, both sides of the limit frame are fixedly connected to proximity switches, the proximity switches control the on and off of the electromagnet, and the inner top surface of the hanger is fixedly connected to multiple groups of downward telescopic rods, and the telescopic ends of the downward telescopic rods are hinged to fixed plates.

[0013] Preferably, a rubber plate is fixedly connected to the top surface of the transfer platform, and the telescopic end of the hydraulic rod extends out from the interior of the sliding block.

[0014] Preferably, a straight slide groove corresponding to the bracket is provided inside the slider, and a spring is elastically connected between the inner wall of the straight slide groove and the side surface of the bracket, and the spring pushes the bracket to move the chuck in a direction away from the slider.

[0018] 2. Secondly, through the provided lifting part, when sawing, the moving device drives the sawing part and the lifting part to move. After the cutting starts, as the band saw moves forward, a cutting mark is left on the log. At this time, when the lifting part moves forward, the long roller enters the cutting mark. As the lifting part continues to move, the hanging plate also enters the cutting mark. On the one hand, the thickness of the hanging plate props up the cut wooden board to prevent the cut part from being deformed due to gravity and close to the log below during the cutting process, causing the saw blade to be clamped from top to bottom, resulting in reduced cutting efficiency. At the same time, when the saw blade is clamped by the wooden board, its heat dissipation area is reduced, and metal fatigue is prone to occur, affecting the service life of the saw blade.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 7 As shown, an embodiment of the present invention provides a log and plank clamping and conveying device, comprising a track 1, a power unit 2 and a moving device 3, wherein the moving device 3 is slidably mounted on the track 1 and moves along the surface of the track 1, and further comprises:

[0029] A sawing part 4, which slides on the track 1 and saws the logs when working;

[0030] The lifting part 5 comprises a symmetrical second sliding seat 51 slidably connected to the track 1, a plurality of second sliding posts 52 are fixedly connected to the top surface of the second sliding seat 51, a hanger 53 that moves up and down is slidably connected to the second sliding posts 52, and the hanger 53 is inserted into the cut produced by the band saw 43 during the sawing process;

[0031] The conveying part 6 includes a sliding frame 61, and two screw rods 62 with opposite thread directions are rotatably installed inside the sliding frame 61. A slider 63 threadedly connected to the two screw rods 62 is slidably connected inside the sliding frame 61. A vertical rotating shaft 614 is rotatably installed inside the slider 63. The two ends of the rotating shaft 614 are coplanar with the outer surface of the slider 63. The top surface of the rotating shaft 614 is fixedly connected to a transfer platform 64. The interior of the transfer platform 64 is fixedly connected with two hydraulic rods 66 and two hydraulic motors 612. The hydraulic rod 66 is communicated with the hydraulic motor 612. The output shaft of the hydraulic motor 612 is fixedly sleeved with a first gear 613. The interior of the slider 63 is slidably connected with a bracket 67 extending on both sides of the slider in the forward direction. The interior of the bracket 67 is fixedly connected with a first rack 69, which is meshed with the first rack 69. The end of the bracket 67 away from the slider 63 is fixedly connected with a chuck 68.

[0032] In the present invention, through the provided conveying part 6, when the sawn wooden board is transported by the lifting part 5 and falls on the transfer platform 64, the wooden board pushes the telescopic end of the hydraulic rod 66, so that the hydraulic motor 612 rotates, thereby driving the first gear 613 to rotate, thereby driving the first rack 69 meshing with the first gear 613 to move, and the first rack 69 drives the bracket 67 connected thereto to approach each other, thereby bringing the two clamps 68 closer to each other, so that the two clamps 68 clamp the two ends of the wooden board to prevent the wooden board from shaking on the transfer platform 64 when the slider 63 moves. 63 moves, the second gear 615 contacts and meshes with the second rack 616, and the second gear 615 and the rotating shaft 614 rotate, thereby driving the transfer platform 64 to rotate. At this time, the clamped wooden board moves together with the rotation of the transfer platform 64, so that the long side of the wooden board is switched from being parallel to the sliding frame 61 to being perpendicular to the sliding frame 61. At this time, the two ends of the wooden board are no longer above the sliding frame 61. At this time, a hydraulic telescopic rod or other device can be used to lift it up and transfer it from the bottom of the wooden board, avoiding dents on the bottom surface of the wooden board when transported by a forklift, thereby ensuring the quality of the wooden board before and after transportation.

[0033] Secondly, through the provided lifting part 5, during sawing, the moving device 3 drives the sawing part 4 and the lifting part 5 to move. After the cutting starts, as the band saw 43 moves forward, a cutting mark is left on the log. At this time, when the lifting part 5 moves forward, the long roller enters the cutting mark. As the lifting part 5 continues to move, the hanging plate 59 also enters the cutting mark. On the one hand, the thickness of the hanging plate 59 props up the cut wooden board to prevent the cut part from being deformed due to gravity and close to the log below during the cutting process, causing the saw blade to be clamped from top to bottom, resulting in reduced cutting efficiency. At the same time, when the saw blade is clamped by the wooden board, its heat dissipation area is reduced, and metal fatigue is prone to occur, which affects the service life of the saw blade.

[0034] like Figure 1 As shown, the power unit 2 includes a reduction gear 21 and a motor 22 fixedly connected to the side of the sliding frame 61 away from the sawing portion 4. The reduction gear 21 is a dual-output reducer. The output end of the reduction gear 21 is transmission-connected to two screw rods 62, and the two output shafts of the reduction gear 21 rotate in opposite directions.

[0035] The deceleration device 21 serves to decelerate the power of the motor 22 to increase the torque and thus increase the load. When the two screw rods 62 are used to drive the slider 63 to move, the movement process of the slider 63 is more stable.

[0036] like Figure 2 As shown, the sawing part 4 includes a first sliding seat 41 symmetrically connected to the track 1 in a sliding manner, a plurality of first sliding columns 42 are fixedly connected to the top surface of the first sliding seat 41, a band saw 43 is slidingly connected to the outer surface of the first sliding column 42, a first telescopic rod 44 is fixedly connected to the top surface of the first sliding seat 41, and the telescopic end of the first telescopic rod 44 is fixed to the bottom surface of the band saw 43.

[0037] like Figure 3 and Figure 4 As shown, the lifting part 5 also includes a second telescopic rod 54 fixedly connected to the top surface of the second sliding seat 51, the telescopic end of the second telescopic rod 54 is connected to the hanger 53 and drives it to move up and down, a plurality of hanging plates 59 are fixedly connected to the inner side surface of the hanger 53, a plurality of long rollers 510 are rotatably installed on the inner side surface of the hanger 53, the diameter of the long rollers 510 is less than or equal to the height of the hanging plates 59, and the long rollers 510 are located in front of the side of the hanging plates 59 facing the sawing part 4. The lifting part 5 also includes a limit frame 56 slidably connected to the track 1, the side of the hanger 53 away from the sawing part 4 is fixedly connected to the suction plate 55, the side of the limit frame 56 is fixedly connected to the electromagnet 58, the two sides of the limit frame 56 are fixedly connected to the proximity switch 57, the proximity switch 57 controls the on and off of the electromagnet 58, and the inner top surface of the hanger 53 is fixedly connected to a plurality of groups of downward telescopic rods 511, and the telescopic ends of the downward telescopic rods 511 are hinged to the fixed plates 512.

[0038] The setting of the hanging plate 59 allows the hanging plate 59 to be inserted into the cutting mark after the sawing part 4 moves forward and saws the log, and then lifts the cut part upward to prevent the cut part from bending under the action of gravity and pressing the saw blade of the band saw 43, causing the working efficiency of the band saw 43 to decrease. At the same time, it also avoids the reduction of the heat dissipation area of ​​the band saw 43 after being clamped by the log, resulting in the metal performance degradation after the band saw overheats during the cutting process, and then resulting in its service life being reduced.

[0039] When the sawn wooden board is lifted by the hanger 53 and transported to the transfer platform 64, the wooden board falls on the transfer platform 64. At this time, the telescopic end of the hydraulic rod 66 is pushed downward, and the liquid in the hydraulic rod 66 is pushed into the hydraulic motor 612, so that the hydraulic motor 612 rotates, and then the first gear 613 rotates, driving the first rack 69 to move, and then the chucks 68 at both ends are close to each other, and then the two chucks 68 clamp the wooden board on the transfer platform 64 to prevent shaking during the movement of the slider 63.

[0040] like Figures 5 to 7 As shown, a rubber plate 65 is fixedly connected to the top surface of the transfer platform 64, and the telescopic end of the hydraulic rod 66 extends from the inside of the slider 63. A straight slide groove 610 corresponding to the bracket 67 is provided inside the slider 63, and a spring 611 is elastically connected between the inner wall of the straight slide groove 610 and the side of the bracket 67. The spring 611 pushes the bracket 67 to move the clamp 68 away from the slider 63. A second gear 615 is fixedly sleeved at the bottom end of the rotating shaft 614, and a second rack 616 is fixedly connected to the inner side of the sliding frame 61. The length of the second rack 616 is such that after the second gear 615 meshes with it and rotates, the second gear 615 rotates 90 degrees.

[0041] The setting of the rubber plate 65 ensures that after the wooden board contacts the rubber plate 65 , the friction force of the rubber plate 65 further fixes the wooden board, thereby preventing the wooden board from shaking during the rotation of the transfer platform 64 and affecting the subsequent transfer and transportation work.

[0042] When the wooden board leaves the transfer platform 64, the elastic force of the spring 611 pushes the first rack 69 to move to the outside of the slider 63, thereby resetting the chuck 68 and the bracket 67. When the motor 22 drives the slider 63 to move back to the sawing part 4, the second gear 615 and the second rack 616 are reversed through meshing transmission and automatically reset.

[0043] Working principle:

[0044] When using the device to assist in cutting boards and transporting the cut boards, first fix the log in front of the sawing section 4, then use the first telescopic rod 44 to adjust the height of the band saw 43, and then use the second telescopic rod 54 to adjust the height of the hanger 53, so that the bottom surface of the hanging plate 59 inside the hanger 53 and the cut surface of the top of the log are in the same plane, and then start the moving device 3 to drive the sawing section 4 and the lifting section 5 to move forward. After the band saw 43 cuts the log, as the cutting depth increases, the hanging plate 59 enters the cutting mark, and the cut part is lifted up by the hanging plate 59. When the sawing section 4 completes cutting the log, After that, the cut wooden board enters the hanger 53, so that the wooden board is lifted, and then the moving device 3 is controlled to return, so that the sawing part 4 enters the next cutting process. On the way back, the downward telescopic rod 511 is extended to make the fixed plate 512 abut against the surface of the wooden board to prevent the wooden board from shaking during the return process and affecting the transportation of the subsequent conveying part 6. As the lifting part 5 returns, it gradually approaches the limit frame 56. When it approaches and triggers the proximity switch 57, the electromagnet 58 is started, and the lifting part 5 is driven to move toward the limit frame 56 through the attraction plate 55. Finally, the hanger 53 contacts the limit frame 56 to ensure its accurate position.

[0045] When the wooden board is transported to the transfer platform 64, the wooden board pushes the telescopic end of the hydraulic rod 66 downward, thereby driving the hydraulic motor 612 to rotate. At this time, the hydraulic motor 612 drives the first rack 69 to move through the first gear 613, thereby causing the two clamps 68 to move toward the wooden board and clamp the wooden board to ensure the stability of the wooden board during movement. As the slider 63 moves, when it approaches the other end of the sliding frame 61, as the second gear 615 engages with the second rack 616, the transfer platform 64 rotates, thereby causing the wooden board to rotate. At this time, the wooden board can be lifted up by setting a telescopic rod or other device under the wooden board, so that the wooden board can be separated from the conveying part 6. After the wooden board leaves the conveying part 6, the two clamps 68 open under the drive of the spring 611. At this time, the conveying part 6 is returned again through the power unit 2, and the transfer platform 64 will be re-aligned under the meshing transmission of the second gear 615 and the second rack 616.
