[0031] ReferenceFigure 1 、 Figure 2 、 Figure 3 and Figure 4 The utility model discloses an offline device of board, comprising:

[0032] Frame 1;

[0033] Bearing platform 7, bearing platform 7 includes bearing seat 71 and bearing piece 72, bearing piece 72 is fixed to the top of bearing seat 71, bearing seat 71 is slidably connected with frame 1 along the vertical direction, and the vertical direction is the direction of Z axis.

[0034] Limiting seat 10 and conveying roller 11 are arranged at intervals in the first direction and are respectively arranged on both sides of bearing platform 7, the first direction is perpendicular to the vertical direction and the length direction of bearing seat 71 respectively, conveying roller 11 is used to transmit board 15, board 15 is configured to be pushed offline, bearing piece 72 is used to bear board 15 pushed offline, frame 1, limiting seat 10 and conveying roller 11 form a space for the movement of bearing platform 7, and the first direction is Y axis direction.

[0035] Specifically, bearing piece 72 is provided with multiple and is arrayed along the length direction of bearing seat 71, the top of multiple bearing pieces 72 is used to support offline board 15, and the supporting capacity of multiple bearing pieces 72 is strong, since bearing seat 71 is limited to be slidably along the vertical direction, it is explained that bearing platform 7 can be lifted while keeping the sliding connection with frame 1 in the vertical direction, thereby, when the offline device starts to work, board 15 (cut well) is pushed out to bearing piece 72 by offline pushing assembly 20, at this time, bearing platform 7 is lowered along frame 1 by the thickness of a board 15, ensures that bearing piece 72 can receive the next board 15, and the repeated action is continued until the stacking of board 15 is completed, and since the sliding connection is arranged, it is ensured that bearing platform 7 always moves along the vertical direction, thereby guaranteeing that the stacked board 15 and bearing platform 7 can be lowered along frame 1 in the space formed by frame 1, limiting seat 10 and conveying roller 11 when stacking, reduce the risk of side turning.

[0036] When the stacking of board 15 reaches a certain height (in the bearing range of bearing platform 7), is lifted by a crown block and the like, to meet the processing demand of accident billet, and similarly, when working next time, bearing platform 7 also slides upward along frame 1, and side turning does not occur.

[0037] Further, the limiting guide assembly 6 is further included, which comprises guide pieces 61, elastic connecting pieces 62 and lifting frames 63, the lifting frames 63 are slidably arranged on the bearing seats 71 in the vertical direction, the guide pieces 61 are symmetrically arranged on both sides of the lifting frames 63 in the first direction, one end of the guide pieces 61 is hinged to the lifting frames 63, and the other end is a free end and located at the top end position of the bearing pieces 72, the elastic connecting pieces 62 are used for connecting the guide pieces 61 and the lifting frames 63, the lifting frames 63 are further provided with limiting guide driving assemblies, the limiting guide driving assemblies are connected with the two groups of guide pieces 61 to drive the two groups of guide pieces 61 to be opened and respectively close to the conveying rollers 11 and the limiting seats 10.

[0038] Specifically, a certain gap is arranged between the two sides of the bearing table 7 and the limiting seats 10 and the conveying rollers 11, so as to ensure that the space meets the storage of the plates 15, and it is also relatively easy to lift the plates 15 by the overhead crane and the like, and the stacked plates 15 can also be pushed out by the upward movement of the bearing table 7, so as to be lifted by the overhead crane and the like, considering the existence of the gap, the limiting guide assembly 6 and the limiting guide driving assembly are arranged, the two groups of guide pieces 61 are driven to be opened and respectively close to the conveying rollers 11 and the limiting seats 10 by the limiting guide driving assembly, so that the gap is reduced or even disappeared, the gap between the guide pieces 61 and the edges of the conveying rollers 11 and the limiting seats 10 is small enough or directly abuts on the roller frame of the conveying rollers 11 and the edges of the limiting seats 10, at this time, the opening formed between the two groups of guide pieces 61 and the bearing pieces 72 is upward, and the closer to the surface of the conveying rollers 11, the larger the opening, it can be seen that, since the guide pieces 61 are hinged to the lifting frames 63 and extend to the top end position of the bearing pieces 72, the guide pieces 61 are arranged in an inclined manner, that is, the space formed between the two groups of guide pieces 61 and the bearing pieces 72 for carrying the plates 15 is approximately inverted trapezoidal (as shown in the figure) Figure 3The two sets of guide pieces 61 are connected by elastic connecting pieces 62, and the two sets of guide pieces 61 are connected to the lifting frame 63. When the lifting frame 63 is lifted, the two sets of guide pieces 61 are opened, and when the lifting frame 63 is lowered, the two sets of guide pieces 61 are closed. When the two sets of guide pieces 61 are opened, the two ends of the bearing piece 72 are limited by the two sets of guide pieces 61, and the gap is reduced, so that the off-line plate 15 is pushed out, and the off-line plate 15 is guided, and the plate 15 is prevented from being stuck in the gap between the bearing table 7, the limiting seat 10 and the conveying roller 11. Further, since the lifting frame 63 is slidably arranged in the vertical direction, the limiting and guiding assembly 6 is vertically adjustable, and can adapt to the lowering of the bearing table 7, that is, as the stacking height of the plate 15 increases, the limiting and guiding assembly 6 can be lifted in the vertical direction (at least the same height), so that the guide pieces 61 can still play a limiting and guiding role after the bearing table 7 is lowered. Thus, when the plate 15 on the conveying roller 11 is off-line pushed out at the same position each time, the position of the plate 15 falling on the bearing table 7 changes less, the plate 15 tends to be stacked neatly, further plays a role in preventing side turning, thereby ensuring safe and smooth stacking. The elastic connecting pieces 62 are arranged to have a tendency to rotate towards each other, and can be in a stretched state, so that when the limiting and guiding driving assembly 61 is weakly opened, the guide pieces 61 can be reset under the contraction of the elastic connecting pieces 62.
