[0029] The material receiving device 3 is located outside the outlet of the sanding machine body 1 and is used to receive the wood output by the sanding machine body 1;

[0030] The lifting device 4 is used to drive the material receiving device 3 to rise or fall;

[0031] The positioning device 5 includes a side positioning device 51 and a front positioning device 52, wherein the side positioning device 51 is used to position the side of the wood so that the side of the wood is aligned, and the front positioning device 52 is used to position the front of the wood so that the front of the wood is aligned;

[0032] The control device is respectively connected to the lifting device 4, the positioning device 5, and the sensing device 6 and controls the lifting device 4, the positioning device 5, and the sensing device 6;

[0033] The sensing device 6 includes a sheet material sensing device 61 and a positioning sensing device 62. The sheet material sensing device 61 is used to sense whether the wood is output from the sanding machine body 1 to the material receiving device 3. If the wood is located on the material receiving device 3, the control device controls the positioning device 5 to start to position the wood. The positioning sensing device 62 is used to sense whether the positioning of the wood is completed. If the positioning of the wood is completed, the control device controls the lifting device 4 to drive the material receiving device 3 to descend to the height of a piece of wood to receive the next piece of wood.

[0034] The wood sanding machine with automatic unloading of the present invention comprises a supporting frame 2, a material receiving device 3, a lifting device 4, a positioning device 5, a sensing device 6, and a control device. After the sanding machine body 1 processes the wood, it outputs the wood from its outlet, and the material receiving device 3 located outside the outlet receives the wood. When the sheet material sensing device 61 senses that the wood is completely located in the material receiving device 3, the control device controls the positioning device 5 to start, the side positioning device 51 positions the side of the wood, and the front positioning device 52 positions the front of the wood to ensure that the wood is flat on the material receiving device 3. When the positioning sensing device 62 senses that the wood is completely positioned, the control device starts the lifting device 4, and the lifting device 4 drives the material receiving device 3 to drop a height of a wood to receive the next piece of wood. The above operation is repeated to make the wood neatly stacked on the material receiving device 3, to avoid the wood from being misplaced and stuck, and to facilitate subsequent picking, thereby improving work efficiency.

[0035] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0036] In this embodiment, the material receiving device 3 includes a discharging pin assembly, which is arranged on the support frame 2 and can move up and down. The lifting device 4 includes a connecting rod 41, two hydraulic cylinders 42, two sets of matching sprockets 43 and chains 44. The connecting rod 41 is connected between the two sprockets 43, and the hydraulic cylinder 42 is used to drive the connecting rod 41 to move up and down. One end of the chain 44 is connected to the support frame 2, and the other end is connected to the discharging pin assembly. The discharging pin assembly can move up and down on the supporting frame 2, and the hydraulic cylinder 42 drives the connecting rod 41 to move up and down, thereby driving the sprocket 43 to move up and down. Since one end of the chain 44 is connected and fixed to the supporting frame 2, the end connected to the discharging pin assembly moves up and down driven by the sprocket 43, thereby driving the discharging pin assembly to move up and down, thereby realizing the lifting and lowering of the discharging pin assembly. Two hydraulic cylinders 42, two sets of matching sprockets 43 and chains 44 are used, and then they are connected by the connecting rod 41 to ensure that the discharging pin assembly is lifted and lowered more smoothly, and to ensure that the wooden board is placed horizontally on the discharging pin assembly.

[0037] In this embodiment, a support assembly 21 is provided on the support frame 2, and the support assembly 21 is used to support the sensing device 6 and the side positioning device 51. The support assembly 21 is provided on the support frame 2 to support the sensing device 6 and the side positioning device 51 through the support assembly 21.

[0038] In this embodiment, the support frame 2 is provided with a position adjustment component 22, and the position adjustment component 22 is used to adjust the height of the support component 21 according to the height of the wood. The position adjustment component 22 is provided on the support frame 2. Since the heights of different batches of wood may be different, the heights of the sensing device 6 and the side positioning device 51 need to be adjusted according to the height of the wood. Therefore, the height of the support component 21 is adjusted by the position adjustment component 22, and then the heights of the sensing device 6 and the side positioning device 51 are adjusted to match the wood of different heights.

[0039] In this embodiment, the positioning assembly 22 includes a cylinder, which is used to drive the support assembly 21 to move up and down. The positioning assembly 22 uses a cylinder to drive the support assembly 21 to move up and down, but is not limited to this. A drive assembly that can achieve up and down movement, such as a screw assembly, a sprocket 43 chain 44 assembly, etc., can also be used.

[0040] In this embodiment, the side positioning device 51 includes an inner plate 511, an outer plate 512, and a lateral drive cylinder 513. The inner plate 511 is arranged on the material receiving device 3 and aligned with the inner side of the material outlet of the sanding machine body 1. The outer plate 512 is aligned with the material outlet of the sanding machine body 1 in height. The lateral drive cylinder is connected to the support frame 2 and is used to drive the outer plate 512 to move inward and outward, so that the outer plate 512 moves toward or away from the inner plate 511. When the wood is completely located in the material receiving device 3, the side positioning device 51 drives the outer plate 512 to move inward by driving the cylinder to squeeze the wood, ensure that the wood board is tightly attached to the inner plate 511, and complete the positioning of the wood board in the lateral direction.

[0041] In this embodiment, the front positioning device 52 includes a support seat 521, a forward drive cylinder 522, and a front end plate 523. The support seat 521 is located at the front side of the support frame 2 and is used to support the forward drive cylinder 522. The forward drive cylinder 522 is used to drive the front end plate 523 to move left and right to move toward or away from the support frame 2. The front end plate 523 faces the outlet of the sanding machine body 1. When the wood is completely located in the material receiving device 3, the front positioning device 52 drives the front end plate 523 to move toward the support frame 2 through the forward drive cylinder 522. Since the front end plate 523 faces the outlet of the sanding machine body 1, the front end plate 523 will push the wood to move left and right to the set position, completing the positioning of the wood in the front direction. Combined with the positioning of the side, each piece of wood processed thereafter will be neatly stacked on the material receiving device 3 after positioning.

[0042] In this embodiment, the support seat 521 is connected to a transverse position adjustment component 53, and the transverse position adjustment component 53 is used to drive the support seat 521 to move left and right, so as to adjust the position of the support seat 521 according to the length of the wood. Since the lengths of different batches of wood may be different, it is necessary to adjust the position of the front positioning device 52 in the length direction to adapt to wood of different lengths. The transverse position adjustment component 53 is connected to the support seat 521, so as to drive the support seat 521 to move left and right through the transverse position adjustment component 53, and adjust the position of the front positioning device 52.

[0043] In this embodiment, the lateral position adjustment assembly 53 includes a base 531, a screw rod 532 and a screw rod slider 533 that cooperate with each other. The screw rod 532 is rotatably arranged on the base 531, the screw rod slider 533 is connected to the support seat 521, and a rotating handle 534 is arranged at one end of the screw rod 532. The lateral position adjustment assembly 53 drives the screw rod to rotate by rotating the rotating handle 534, and drives the screw rod slider 533 and the support seat 521 to move left and right, so as to adjust the position of the front positioning device 52.
