Bar automatic screening material stacking machine and method

Abstract

The invention provides a bar automatic screening material stacking machine and method. The section size of each bar is detected through a first CCD detection device, the bars are grabbed into a data plate through a clamping jaw, the size data of each bar in the data plate are recorded at the moment, the bars of the appropriate size are grabbed through the clamping jaw, placed in a rotation device,rotated to the appropriate angle, then pushed into an elastic clamp, arranged in rows and then pushed into a mold, and in this way, installation of each layer of bars is completed. By means of the bar automatic screening material stacking machine, the size of the bars installed in the mold can be matched with the mold size, the sizes of the bars can also be matched, no gaps are formed between thebars or between the bars and the mold, mutual abrasion cannot be caused between the bars in the transportation process, and quality of the bars is ensured.

Description

technical field [0001] The application relates to an automatic bar material screening and stacking machine and method. Background technique [0002] Rods generally refer to a material product whose cross-sectional shape is a simple figure such as a circle, square, hexagon, octagon, etc., and whose length is relatively large compared to the cross-sectional size, and is usually provided in a straight strip. [0003] In the prior art, the bar needs to be placed in the mold, and the placing process is usually done manually. When stacking bars, it is usually laid layer by layer, and the upper layer of bars is laid on the lower layer of bars. Taking the bar with a hexagonal cross-section as an example, the upper surfaces of two adjacent bars in the same layer just form a circle. The installation groove for a hexagonal rod can be installed, and the rods can be installed in the installation groove in turn to complete the laying of the upper layer of rods. [0004] However, the exi...

Problems solved by technology

[0004] However, the existing manual operation will have the following defects: due to the tolerance of the diameter of the rods, when laying manually, it cannot be guaranteed that the total width of a layer of rods after laying is just matched with the mold. There is a gap, and the rods will shake in the mold during transportation, which will cause the wear of the rods; when laying the upper rods in the lower rods one by one, it is necessary to select the appropriate size of the rods and the installation groove of the lower layer Matching, this process is very difficult to select by the naked eye, and it needs to be manually tried one by one

Taking the hexagonal bar as an example, there is also a tolerance between the distances between the opposite sides of each bar section, so not only must the appropriate bar be rotated, but also the placement angle of the bar needs to be adjusted to achieve the most suitable position, if This result is completed only by manpower, which is time-consuming, labor-intensive and inefficient
