[0026] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See also Figures 1 to 3 The chain conveyor shown in the figure includes a frame 100, and the entire frame 100 is divided into at least a stacking area 110 and a fork-off area 120 along the length direction. The stacking area 110 and the fork-off area 120 can be directly connected, or an isolation area 130 can be set in the middle, which is set according to needs.

[0028] In the stacking area 110, the finished panels 200 are stacked in the stacking area 110 by virtue of the natural drop of the rollers 300 in the production line.

[0029] In order to convey the stacked finished boards in the stacking area 110 to the forking area 120, a plurality of chain conveying units 400 are arranged on the frame 100 at intervals along the width direction of the frame 100. Each chain conveying unit at least includes a driving sprocket 410, a chain 420 and a reversing tensioning sprocket 430. Of course, the reversing tensioning sprocket 430 can be divided into a reversing sprocket and a tensioning sprocket. In addition, other intermediate sprockets can be used to support the chain 420 as needed.

[0030] All the driving sprockets 410 are arranged at the end of the stacking area 110, that is, the end position of one end in the length direction of the frame 100, and all the reversing tensioning sprockets 430 are arranged at the end of the fork separation area 120, that is, the end position of the other end in the length direction of the frame 100. All the chains 420 are wrapped around the corresponding driving sprockets 410 and the reversing tensioning sprockets 430, so that the chains 420 in each chain conveying unit can circulate between the stacking area 110 and the fork separation area 120 by relying on the rotation of the driving sprockets 410 and the reversing tensioning sprockets 430, and all the chain conveying units 400 convey the finished boards stacked in the stacking area 110 to the fork separation area 120, and the stacked finished boards 200 conveyed to the fork separation area 120 are forked and sent out by a forklift.

[0031] In order to enable the stacked finished panels 200 conveyed to the forklift area 120 to be forked out by a forklift, a forklift arm that allows a forklift to extend into a forklift slot 121 is provided between the chains 420 of the adjacent chain conveying units 400 in the forklift area 120. The position of the forklift slot 121 is lower than that of the chain 420, so that the forklift arm can fork into the forklift slot 121 to fork up the stacked finished panels 200 in the forklift area 120.

[0032] All chain conveying units are synchronously driven by a motor reducer unit 440. The motor reducer unit 440 is installed at the end of the stacking area 110, that is, the end position of one end in the length direction of the frame 100. The drive shaft 441 in the motor reducer unit 440 is fixedly connected to the driving sprockets 410 in all chain conveying units, so that when the motor reducer unit 440 is working, the drive shaft 441 rotates, driving each driving sprocket 410 to rotate. All the reversing tensioning sprockets 430 configured at the end of the fork separation area 120 are each axially arranged on the frame 100.

[0033] In order to prevent the first finished board 200 from colliding with the chain 420 of the stacking area 110 when falling into the stacking area 110, the present invention provides an elastic inclined plate mechanism 500 on one side of the chain 420 in each chain conveying unit 400 in the middle of the stacking area 110, and an elastic inclined plate mechanism 500 is also provided on the inner side of the chain 420 in the chain conveying unit 400 on the side of the stacking area 110 away from the board feeding side.

[0034] The elastic inclined plate mechanism 500 includes a first inclined plate bracket 510, a second inclined plate bracket 520, an inclined plate 530, a spring 540 and a spring bolt 550. The first inclined plate bracket 510 is located between the chain 420 and the second inclined plate bracket 520. The end 532 of the inclined plate 530 away from the chain 420 to be protected is hinged on the second inclined plate bracket 520. After the spring bolt 550 is sleeved with the spring 540, it passes through the through hole 511a on the spring base plate 511 on the first inclined plate bracket 510 and is tightened with a nut 551. The upper end of the spring 540 acts on the bolt head 552 of the spring bolt 550, and the lower end of the spring 540 acts on the spring base plate 511. The spring 540 drives the spring bolt 550 to float up and down; the bolt head 552 of the spring bolt 550 supports the inclined plate 530 under the action of the spring 540.

[0035] The upper surface 534 between the action point 533 between the inclined plate 530 and the bolt head 552 of the spring bolt 550 and the end 531 of the inclined plate 530 close to the chain 420 to be protected is a plane, which is higher than the surface of the chain 420 to be protected. The upper surface 535 between the action point 533 between the inclined plate 530 and the bolt head 552 of the spring bolt 550 and the end 532 of the inclined plate 530 away from the chain 420 to be protected is a downward inclined surface.

[0036] A buffer pad 512 is also provided on the first inclined plate bracket 510. When the inclined plate 530 is pressed downward by an external force, the buffer pad 512 forms a buffer support for the end 531 of the inclined plate 530 close to the chain 420 to be protected.

[0037] In addition, a flat plate mechanism 600 is provided on the other side of the chain 420 in each chain conveyor unit 400 in the middle of the stacking area 110. For the chain conveyor unit 400 in the middle position, the flat plate mechanism 600 and the elastic inclined plate mechanism 500 are respectively provided on both sides of the movement direction of the chain 420. A flat plate mechanism 600 is also provided on the inner side of the chain 420 in the chain conveyor unit 400 on the side where the stacking area 110 enters the board.

[0038] Each plate mechanism 600 further includes a plate support 610 and a plate 620, wherein the bottom of the plate support 610 is fixed to the frame 100, and the plate 620 is fixed to the top of the plate support 610. The upper surface of the plate 620 in each plate mechanism 600 is slightly lower than the surface of the chain 420, so as to facilitate the conveyance of the stacked finished plates 200.

[0039] In addition, in order to smoothly introduce the finished boards into the stacking area 110, an introduction bar assembly 700 is disposed on both sides of the stacking area 110 of the rack 100 parallel to the running direction of the chain 420, and the upper ends of the introduction bars 710 in all the introduction bar assemblies 700 are tilted outwards. In this way, the finished boards 200 can be introduced into the stacking area 110 for stacking by natural drop.

[0040] In addition, in order to sense whether the first finished board 200 is introduced into the stacking area 110, a first sensing device 800 is configured on the rack 100 of the stacking area 110 to sense the first finished board 200 entering the stacking area 110. The first sensing device 800 is a photoelectric switch. The sensing signal of the first sensing device 800 can be used to control the motor reducer unit 440 and the counting device. In addition, a second sensing device 900 is provided on the side of the rack 100 of the stacking area 110 to detect the stacking height of the finished boards in the stacking area 110. The second sensing device 900 is a photoelectric switch, which is used to detect the height of the stacking, and then control the working state of the motor reducer unit 440.
