Description

Automatic stacking machine and method

The invention relates to an automatic stacking machine and an automatic stacking method which can control and neatly stack sheet materials in an automated manner.

At present, the sheet material is cut into a predetermined size and then stacked on a carrier board by an automatic stacker so as to be transported to the storage area for use or the next processing area for subsequent processing steps. The composition structure of the existing automatic stacker is mainly installed on the machine on the material conveying device. The rear end of the machine is provided with a lifting bearing device. The lifting bearing device has a bearing frame that can be driven by the driving mechanism to move up and down.

The auxiliary bracket 41 continues to stack the materials; the step of removing the carrier plate 70 with the stacked material 80 from the stacking area step is to move the carrier plate 70 stacked with a certain amount of material 80 from the stacking area and place it on the carrier 22 Reposition the carrier plate 70 and lift the carrier plate 70 below the auxiliary bracket 41; and the steps of retracting the auxiliary bracket 41 and the material 80 and transferring to the carrier plate 70 are to retract the auxiliary bracket 41 and make the original stack on the auxiliary bracket 41 The material 80 is transferred to the carrier plate 70 of the carrier 22, and the material transportation and Lamination step.

As shown in FIG. 14, with reference to FIGS. 8 to 12, another automatic stacking method provided by the present invention includes the following steps: Material conveying and stacking steps, which provide a large number of materials 80 to be sequentially conveyed to the stacking area. On the carrier plate 70 carried by the liftable carrier frame 22, the carrier plate 22 and the carrier plate 70 of the carrier material 80 are gradually lowered according to the amount of the stacked material 80 until the carrier plates 70 carried by the carrier frame 22 are stacked. A certain amount of material 80; providing an auxiliary bracket 41 to continue the step of stacking the material 80, so that the auxiliary bracket 41 extends above the carrier plate 70 on which the material 80 is stacked in the stacking area, and the material 80 is continuously conveyed to the stacking area The auxiliary bracket 41 continues to stack the material 80; the steps of moving the carrier plate 70 stacked with the material 80 away from the stacking area and transporting the carrier plate 70 to the carrier 22 in the stacking area make the stacking of the carrier plate with a certain amount of material 80 70 is transferred from the stacking area to the completion area, and at the same time, a carrier plate 70 is conveyed from the preparatory area to the carrier 22 in the stacking area, and then the carrier 70 is lifted from the carrier 22 in the stacking area to the auxiliary bracket 41; And the steps of retracting the auxiliary bracket 41 and the material 80 and transferring them to the carrier board 70 are to retract the auxiliary bracket The rack 41 moves the material 80 originally stacked on the auxiliary bracket 41 to the carrier plate 70 of the carrier 22, and returns to the material 80 conveying and stacking steps.

From the foregoing description, it can be known that the automatic stacker of the present invention uses an auxiliary support device installed in the machine to prepare a material of a predetermined height (or quantity) on a carrier plate carried by a carrier of a lifting and lowering device, and then prepares to move out of the stacking area. With the support of the support translation device, the pan translation drive unit drives the auxiliary support to extend above the carrier plate stacked with materials at the back of the machine, so that the machine's material conveying device can continuously transport the material to be stacked on the auxiliary support until The carrier rack repositions a carrier board, and the carrier rack and its carrier board are lifted to the lower side of the auxiliary bracket by the lifting frame. The bracket translation drive unit of the auxiliary supporting device drives the auxiliary bracket to be retracted into the machine, so that the original stacking The materials on the auxiliary bracket are directly transferred to the carrier plate on the carrier frame, and then the stacking operation is continued; the automatic stacking method proposed by the present invention also uses the same technical means as described above. In this way, the normal conveying speed of the material can be maintained, and the existing automatic stacker is required to suspend the material conveying device to transport the material when it is ready to move out of the stacking area after the material is stacked on the carrier board at a predetermined height (or quantity). Therefore, the present invention can effectively improve the operation efficiency of automatic stacking.
