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

[0027] like Figures 1 to 7 As shown, the automatic unloading and stacking device for bamboo curtains of this embodiment includes a frame 1, a material shifting mechanism 2, a material dividing mechanism 3, a manipulator 5, a stacking platform 6 and two material receiving rods 4. At least three telescopic support mechanisms 11 are provided on one side of the frame 1, and at least three telescopic support mechanisms 11 are provided on the other side. The two material receiving rods 4 are respectively supported on the telescopic support mechanisms 11 on both sides, and the telescopic support mechanisms 11 on both sides are arranged opposite to each other. The front end of the material receiving rod 4 can be extended into the gap of the bamboo curtain 8 at the end of the circulating chain 7 of the tunnel furnace. The material shifting mechanism 2 is used to shift the bamboo curtain 8 at the end of the circulating chain 7 backward along the material receiving rod 4. The material dividing mechanism 3 is movably arranged on the frame 1 for grouping the bamboo curtains 8 on the material receiving rod 4. The stacking platform 6 is arranged on the frame 1, and the manipulator 5 is arranged between the material receiving rod 4 and the stacking platform 6, and is used to flip the grouped bamboo curtains 8 to a horizontal state and place them on the stacking platform 6.

[0028] In this embodiment, three telescopic support mechanisms 11 are provided on each side of the frame 1. The receiving rod 4 is directly placed on the telescopic support mechanism 11, and the telescopic support mechanism 11 is in an extended state during support. The telescopic support mechanisms 11 are arranged on the receiving rod 4 from front to back at intervals.

[0029] When the bamboo curtain 8 reaches the end of the endless chain 7, the hooking seam of the bamboo curtain 8 penetrates into the front end of the receiving rod 4. At the same time, when the rotating hook is separated from the bamboo curtain 8, the material shifting mechanism 2 shifts the bamboo curtain 8 on the hook backwards, completing the action of unloading the bamboo curtain 8 from the endless chain 7 to the receiving rod 4. Then, the material dividing mechanism 3 starts to group the bamboo curtains 8 that are close to each other on the receiving rod 4. For example, taking a group of 10 bamboo curtains 8 as an example, the material dividing mechanism 8 divides the 10 bamboo curtains 8 into a group and pushes them backwards along the receiving rod 4 to separate them from other bamboo curtains 8. After grouping, the manipulator 6 flips to the vertical position, clamps a group of bamboo curtains 8, takes the bamboo curtains 8 away from the receiving rod 4, and then flips the bamboo curtains 8 from the vertical state to the horizontal state (see the manipulator 5 for material taking). Figure 7 The three parts a, b, and c in the figure are placed on the stacking platform 6 for stacking, and the stacking action of the bamboo curtain 8 is completed.

[0030] Since the bamboo curtains 8 will move on the receiving rod 4 when grouping, and the receiving rod 4 is supported by the telescopic support mechanism 11, there will be interference. Therefore, during the material division, when the number of bamboo curtains 8 at the front end of the receiving rod 4 reaches a certain amount, the receiving rod 4 on each side is supported by two telescopic support components 11 in the middle and rear ends, and the telescopic support component 11 near the front end is retracted in a direction perpendicular to the receiving rod 4, and the telescopic support component 11 leaves the receiving rod 4. At this time, the material division mechanism 3 divides a group of bamboo curtains 8 and moves a group of bamboo curtains 8 along the receiving rod 4 moves backward from the front to the back, and when it reaches the middle telescopic support assembly 11, the front telescopic support assembly 11 extends to continue supporting the material receiving rod 4, and the middle telescopic support assembly 11 is replaced and retracted, and the material receiving rod 4 is supported by the two telescopic support assemblies 11 at the front and rear ends, and the material dividing mechanism 3 continues to push a group of bamboo curtains 8 to the telescopic support assembly 11 at the rear end. At this time, the material receiving rod 4 is supported by the two telescopic support assemblies 11 at the front and middle ends, and the telescopic support assembly 11 at the rear end retracts, and the manipulator 5 takes a group of bamboo curtains 8 away from the material receiving rod 4. After that, the telescopic support assembly 11 at the rear end extends and resets, and the next cycle is carried out. Among them, the "front end" reference datum is the end of the material receiving rod 4 close to the circulation chain 7.

[0031] The automatic unloading and stacking device for bamboo curtains realizes the full-automatic unloading and stacking of bamboo curtains 8 after they are dried in the tunnel furnace through the arrangement of the material shifting mechanism 2, the material dividing mechanism 3, the manipulator 5, the two material receiving rods 4 and the telescopic support mechanism 11. No human intervention is required in the whole process, the degree of automation is high, and the labor cost is reduced.

[0032] In this embodiment, the end of the material receiving rod 4 facing the circulating chain 7 is a pointed end, which is convenient for inserting into the grouting of the bamboo curtain 8.

[0033] In this embodiment, the telescopic support mechanism 11 is specifically a telescopic cylinder, and a clamping seat 112 is provided at the extended end of the telescopic cylinder, and a horizontal U-shaped groove 111 is provided on the clamping seat 112. The notches of the U-shaped grooves 111 on both sides of the frame 1 are arranged facing each other, and the material receiving rod 4 is placed in each U-shaped groove 111 on the corresponding side. In this way, the telescopic cylinder can directly clamp or leave the material receiving rod 4 when it is extended or retracted.

[0034] In this embodiment, the material dividing mechanism 3 includes a material dividing trolley 31 and a material dividing rod 32. The frame 1 is provided with a material dividing track 12, the material dividing track 12 is arranged above the material receiving rod 4, the material dividing trolley 31 is arranged on the material dividing track 12, and the material dividing rod 32 is arranged on the material dividing trolley 31 in a manner that it can be raised and lowered. When dividing the materials, the material dividing trolley 31 moves to the front end with the material dividing rod 32, and the position of the 10th bamboo curtain is detected by the detection mechanism, and then the material dividing rod 32 is lowered and inserted between the 10th and 11th bamboo curtains 8, and the grouped bamboo curtains 8 are pushed backward to separate the grouped bamboo curtains 8 from the front bamboo curtains 8.

[0035] In this embodiment, the downward end of the material dividing rod 32 is a pointed end, which is convenient for inserting between two close bamboo curtains 8. Since the width of the bamboo curtain 8 is large, two groups of material dividing rods 32 are arranged on the material dividing trolley 31, and the two groups of material dividing rods 32 are arranged on the left and right sides. Each group of material dividing rods 32 is provided with two material dividing rods 32, which are arranged at intervals in front and behind. The front and rear two material dividing rods 32 can work alternately.

[0036] In this embodiment, the material shifting mechanism 2 includes a shifting fork 21, a rocker arm 22 and a material shifting shaft 23. Both ends of the material shifting shaft 23 are installed on the frame 1 through a shaft seat 24. The rocker arm 22 is fixedly connected to the material shifting shaft 23. The shifting fork 21 is vertically arranged and the upper end is hinged to the rocker arm 22.

[0037] Preferably, the power of the material-discharging rotating shaft 23 comes from the power of the endless chain 7. Specifically, a transition rotating shaft 13 is provided on the frame 1, a first driven sprocket 72 is provided on the driving shaft 71 of the endless chain 7, a second driven sprocket 131 and a third driven sprocket 132 are provided on the transition rotating shaft 13, a fourth driven sprocket 231 is provided on the material-discharging rotating shaft 23, a first chain (not shown in the figure) is wound around the first driven sprocket 72 and the second driven sprocket 131, and a second chain (not shown in the figure) is wound around the third driven sprocket 132 and the fourth driven sprocket 231. The driving shaft 71 rotates, the first driven sprocket 72 rotates, the second driven sprocket 131 rotates through the first chain, and then the transition shaft 13 rotates, the third driven sprocket 132 thereon rotates, and the fourth driven sprocket 231 rotates through the second chain, and then the material-dispensing shaft 23 rotates, and the swing rod 22 rotates, and the swing rod 22 swings and the fork 21 moves forward and backward to achieve the bamboo curtain 8 at the end of the circulating chain 7 to be shifted backward. This structure not only realizes that the material-dispensing mechanism 2 and the circulating chain 7 share a power, but also, in the material-dispensing mechanism 2, the material-dispensing shaft 23 rotates one circle, and the fork 21 can be moved up and down and forward and backward, so that the fork 21 can be pushed from the front to the back once, and then rise, retreat, and then fall to push the material again, so that the circulating chain 7 can deliver a bamboo curtain 8 to the front end of the material receiving rod 4, and the fork 21 can be shifted once.

[0038] In this embodiment, the stacking platform 6 is a stacking pallet, a transmission mechanism 14 is provided on the frame 1, and the stacking pallet is provided on the transmission mechanism 14. The stacked bamboo curtains 8 are output through the transmission mechanism 14. In order to improve the neatness of stacking, a pushing mechanism 9 for aligning the stacked bamboo curtains 8 is provided on both sides of the conveying direction of the bamboo curtains 8. When the manipulator 5 stacks the bamboo curtains 8 on the stacking pallet, the bamboo curtains 8 are aligned in the front and rear directions, but are not completely aligned in the left and right directions. By arranging the pushing mechanism 9 on the left and right sides to align the bamboo curtains 8 in the left and right directions, the bamboo curtains 8 are stacked neatly, which is convenient for subsequent production. The pushing mechanism 9 is specifically a pushing cylinder.

[0039] In this embodiment, a moving frame 15 and a moving track 16 are provided on the frame 1, the moving track 16 is provided above the material dividing track 12, and the manipulator 5 is installed on the moving frame 15. The moving track 16 overlaps the material dividing track 12 (material receiving rod 4) end to end, so that the moving frame 15 can move with the manipulator 5 to the top of the end of the material dividing track 12 to clamp the grouped bamboo curtains 8 at the end of the material receiving rod 4.
