Detailed Description

The invention is described in detail below with reference to the drawings and the detailed description.

Referring to fig. 1 to 3, the chain conveyor shown in the drawings includes a frame 100, and the entire frame 100 is divided lengthwise into at least a stacking area 110 and a forking area 120. The stacking region 110 and the forking region 120 can be directly connected, or an isolation region 130 can be disposed therebetween, which is set according to the requirement.

In the stacking zone 110, the finished board 200 is stacked by natural fall to the stacking zone 110 by means of the conveying of the rollers 300 in the production line.

In order to transfer the stacked finished boards of the stacking area 110 to the forking area 120, a plurality of chain transfer units 400 are disposed on the rack 100 at intervals in the width direction of the rack 100. Each chain transport unit includes at least a drive sprocket 410, a chain 420, and a reverse tension sprocket 430. Of course, the reverse tension sprocket 430 can be divided into a reverse sprocket and a tension sprocket. Other intermediate sprockets may be used to support the chain 420 as desired.

All of the drive sprockets 410 are disposed at the end of the stacking area 110, i.e., at one end of the length of the frame 100, and all of the reversing tension sprockets 430 are disposed at the end of the forking area 120, i.e., at the other end of the length of the frame 100. All the chains 420 are wound around the corresponding driving sprockets 410 and the reversing tension sprockets 430, so that the chains 420 in each chain conveying unit can circulate between the stacking area 110 and the forking area 120 by means of the rotation of the driving sprockets 410 and the reversing tension sprockets 430, all the chain conveying units 400 convey the finished boards stacked in the stacking area 110 to the forking area 120, and the stacked finished boards 200 conveyed to the forking area 120 are forked by a forklift.

In order to fork and deliver the stacked finished boards 200 conveyed to the forking area 120 by a forklift, a forklift arm for accommodating the forklift is provided between the chains 420 of the adjacent chain conveying units 400 of the forking area 120 to extend into the forklift groove 121, and the forklift groove 121 is located at a position lower than the position of the chains 420, so that the forklift arm can fork into the forklift groove 121 to fork the stacked finished boards 200 of the forking area 120.

All chain conveyor units are driven synchronously by means of a motor reducer unit 440. The motor reducer unit 440 is installed at the end of the stacking area 110, i.e., at the end of the lengthwise direction of the rack 100. The driving shaft 441 of the motor reducer unit 440 is fixedly connected to the driving sprockets 410 of all the chain conveying units, so that when the motor reducer unit 440 operates, the driving shaft 441 rotates to drive each driving sprocket 410 to rotate. All the reversing tension sprockets 430 arranged at the end of the fork area 120 are each journalled on the frame 100.

In order to prevent the first finished board 200 from hitting the chain 420 of the stacking area 110 when it falls into the stacking area 110, the present invention provides an elastic slant 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 slant plate mechanism 500 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 entry plate.

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

An upper surface 534 between an action point 533 between the swash plate 530 and the bolt head 552 of the spring bolt 550 and the end 531 of the swash plate 530 close to the chain 420 to be protected is a flat surface higher than the surface of the chain 420 to be protected, and an upper surface 535 between the action point 533 between the swash plate 530 and the bolt head 552 of the spring bolt 550 and the end 532 of the swash plate 530 far from the chain 420 to be protected is a slope inclined downward.

A cushion 512 is further disposed on the first swash plate bracket 510, and when the swash plate 530 is pressed by an external force, the cushion 512 forms a cushion support for the end 531 of the swash plate 530 close to the chain 420 to be protected.

Further, a plate mechanism 600 is provided on the other side of the chain 420 in each chain conveying unit 400 in the middle of the stacking area 110, and for the chain conveying unit 400 in the middle position, the plate mechanism 600 and the elastic slope plate mechanism 500 are provided on both sides in the moving direction of the chain 420. A plate mechanism 600 is also provided inside the chain 420 in the chain conveying unit 400 at the side of the stacking area 110 on the plate feeding side.

Each plate mechanism 600 further includes a plate holder 610 and a plate 620, the bottom of the plate holder 610 being fixed to the frame 100, and the plate 620 being fixed to the top of the plate holder 610. The upper surface of the plate 620 in each plate mechanism 600 is slightly lower than the surface of the chain 420, which facilitates the transportation of the stacked finished plates 200.

In addition, in order to smoothly guide the finished boards into the stacking area 110, a guide bar assembly 700 is disposed at each side of the stacking area 110 of the rack 100 parallel to the running direction of the chain 420, and the upper ends of the guide bars 710 of all the guide bar assemblies 700 are inclined outward. This facilitates the stacking of the product plates 200 by natural fall directed into the stacking area 110.

In addition, in order to sense whether the first finished board 200 is guided into the stacking area 110, a first sensing device 800 is disposed on the rack 100 of the stacking area 110 for sensing that the first finished board 200 enters the stacking area 110, and 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 for detecting the stacking height of the product plates in the stacking area 110 is disposed at the side of the rack 100 in the stacking area 110. The second sensing device 900 is a photoelectric switch for detecting the height of the stack, and further controlling the operating state of the motor reducer unit 440.
