The invention is further described below in connection with the accompanying drawings.

The plate material automatic packaging system includes a dimension measuring device, a carton cutting machine, a power transmission roller table, an automatic pre-folding device, a packaging plate transfer table and an automatic sealing device.

The first board 100 is a pre-packaged part after pre-wrapping a plurality of sorted same-order boards. Pre-wrapping refers to pre-wrapping multiple plates with pearl cotton and air bubble film in accordance with packaging regulations, and then winding them with adhesive tape. , the width of the prepackaged part corresponds to the maximum width of the plurality of boards, and the length of the prepackaged part corresponds to the maximum length of the plurality of boards. In this embodiment, the facing surface of the first plate member 100 is shown in FIG.

The dimension measuring device is used to measure the dimension of the first plate material 100, and the carton cutting machine cuts the cardboard material based on the dimension measured by the dimension measuring device to obtain a packaging board. The carton cutter is equipped with six corrugated cardboard storage bins, and the data measured by the dimension measuring device is sent to the carton cutter in a fixed format. The maximum width of corrugated cardboard is 2470mm, and most of the closet board uses the side board, which is mainly 2300mm*600mm, as the bottom board of the packaging. There is The cutting machine can only choose the normal state, and can choose to rotate 90 degrees or not, so the machine always reports that there is no corresponding cardboard size, or wastes a large amount of cardboard. , which is insufficient for cost savings. In contrast, the present application proposes the following, the data measured by the dimension measuring device is selected and optimized, and the dimension measuring device uses a set value (based on the actual utilization rate) of width or length. ), the data can be directly exchanged, rotated and sent to the cutting machine before sending the data, and the cutting direction can be directly controlled, greatly improving the utilization rate of cardboard. At the same time, more corrugated stock can be avoided.

The dimension measuring device currently in general use usually selects the infrared light grid measurement method to measure the height of the first plate material 100, and the randomness of the packaging after winding the adhesive tape. It is too strong, and the air bubble film often rises during transport, so the height of the packaging sensed by the grid is greater than the actual height of the first board, so the cut cartons are taller and the work is more difficult. The operator has to spend a lot of time correcting errors and having to manually re-measure cut sheets, which is inefficient and wastes corrugated board. In order to solve this problem, the present application changed the conventional grid measurement to a mechanical pressure measurement device for height detection, and solved the bubble film floating problem. After running for a period of time, when multiple plates are wrapped together, there will be a void at the detection position of the mechanical pressure measuring device, resulting in a smaller measured value, and finally a new problem that the cut carton will be smaller. Occurred. On this basis, the original scheme was further optimized to align the leading edges of the same order of sorted boards to ensure that all the leading edges of the boards are flush with each other when packaged. , In the process of material loading, ensure that the flush side is the front, so as not to affect the effect of height measurement. After two rounds of optimization, all packages can be successfully measured online.

As shown in FIG. 2, the packaging plate is divided into A folding surface area, B folding surface area and C folding surface area along the longitudinal direction, and the C folding surface area corresponds to the A folding surface area one-to-one. ing. The A folding surface area sequentially includes folding surface A1, folding surface A2, folding surface A3 and folding surface A4, the dimensions of folding surface A2 and folding surface A4 being adapted to the width and height of the first plate 100, The dimensions of folding plane A1 and folding plane A3 are adapted to the height of first plate 100 . The B-folding surface area sequentially includes folding surface B1, folding surface B2, folding surface B3, folding surface B4 and folding surface B5, and the dimensions of folding surface B2 and folding surface B4 are the length and width of the first plate 100. , and the dimensions of folding surface B1, folding surface B3 and folding surface B5 are adapted to the length and height of first plate 100. FIG. The C-folding plane region sequentially includes folding plane C1, folding plane C2, folding plane C3, and folding plane C4.

The swing rod assembly 410 includes a plurality of swing rods arranged side by side, each swing rod positioned between the rod shafts of the second transport unit 220 . The pre-folding is done because it is necessary to check the board material lot and mark the surface of the packaging box before sealing. When the first plate member 100 and the packaging plate reach the corresponding position in the longitudinal direction of the swing rod assembly 410, the moving rod assembly 420 moves toward the first plate member 100, and after reaching the predetermined position, moves the moving rod. The folding surface B3, the folding surface B4 and the folding surface B5 of the packaging plate are lifted upward by controlled lifting, and the operator raises his hand to pull down the folding surface B5, marking the outer surface of the folding surface B4 with letters or graphics.

The press plate is an all-steel monolithic or similar structure that allows the cardboard to be pressed flat and held by a delay setting until the hot-melt adhesive cools and solidifies and adheres firmly to the rollers. The potential problem of wrinkling and misalignment of the cardboard with a wheel press can be avoided. After the operator completes the marking, the second conveying unit 220 conveys the prepackaged first plate material 100 and the packaging plate to the working position of the third conveying unit 230, at which time the first The moving mechanism 510 moves the press plate back and forth to the proper position, the second moving mechanism 520 moves the press plate up and down, and the press mechanism presses the press plate downward. The first moving mechanism 510 is connected to the lower end of the press plate via a plurality of connecting rods interposed between adjacent rollers of the third conveying unit 230 . The first moving mechanism 510 moves back and forth a distance that fits the width of the first plate 100, and the second moving mechanism 520 moves up and down a distance that fits the height of the first plate 100. , after the displacement is completed, the lower end of the pressing plate is aligned with the connecting line between the folding surface B3 and the folding surface B4 of the packaging plate, and at this time, the pressing mechanism makes the folding surface B3 and the folding surface B4 perpendicular to each other. , the pressing plate is controlled to press downward to bring the folding surface B2 of the packaging plate into close contact with the top surface of the first plate 100, at this time, folding surface B5 and folding surface B1, folding surface A2 and folding surface A4, and folding Surface C2 and folding surface C4 are fixed with a hot melt adhesive.
